Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority to U.S. Provisional Patent Application No. 62/813,572, filed on Mar. 4, 2019. The provisional application is incorporated by reference herein. 
    
    
     FIELD 
     This disclosure relates generally to devices and methods for protecting trees, shrubs, and vines. 
     BACKGROUND 
     Plants such as trees, shrubs, and vines are susceptible to various conditions or forces that can inhibit their growth. In some instances, these conditions or forces can damage or even kill the plant. This is particularly true during early stages of plant growth. Some forces that can harm or kill a plant are animals eating or contacting the plant. For example, deer frequently eat saplings and/or rub their antlers against the plant, which can kill or severely damage the plant. Other forces that can harm or kill a plant include contact with herbicides and pesticides that are sprayed around the plant. As a result, devices and methods for protecting plants are desirable.

     DETAILED DESCRIPTION 
     General Considerations 
     For purposes of this description, certain aspects, advantages, and novel features of the embodiments of this disclosure are described herein. The disclosed methods, apparatuses, and systems should not be construed as limiting in any way. Instead, the present disclosure is directed toward all novel and nonobvious features and aspects of the various disclosed embodiments, alone and in various combinations and sub-combinations with one another. The methods, apparatuses, and systems are not limited to any specific aspect or feature or combination thereof, nor do the disclosed embodiments require that any one or more specific advantages be present or problems be solved. 
     Although the operations of some of the disclosed methods are described in a particular, sequential order for convenient presentation, it should be understood that this manner of description encompasses rearrangement, unless a particular ordering is required by specific language. For example, operations described sequentially (e.g., assembly or disassembly of a grow tube) may in some cases be rearranged or performed concurrently. Moreover, for the sake of simplicity, the attached figures may not show the various ways in which the disclosed methods can be used in conjunction with other methods. As used herein, the terms “a”, “an” and “at least one” encompass one or more of the specified element. That is, if two of a particular element are present, one of these elements is also present and thus “an” element is present. The terms “a plurality of” and “plural” mean two or more of the specified element. 
     As used herein, the term “and/or” used between the last two of a list of elements means any one or more of the listed elements. For example, the phrase “A, B, and/or C” means “A,” “B,” “C,” “A and B,” “A and C,” “B and C,” or “A, B, and C.” 
     As used herein, the term “coupled” generally means physically coupled or linked. Two components that are coupled to the each other can be directly connected to each other or can be indirectly connected to each other with one or more intermediate elements between the coupled items. 
     As used herein the term “grow tube” means a device configured for facilitating growth of a plant and/or protecting the plant. For example, grow tubes include devices that can help a tree sapling or a vine cutting to grow. Grow tubes also include, for example, devices that are configured to protect a plant from animals (e.g., insects, rodents, etc.) and/or chemicals (e.g., pesticides, herbicides, etc.). 
     Exemplary Embodiments 
       FIGS. 1-9  show a grow tube  100 , according to one embodiment. The grow tube  100  can be placed around a plant to protect the plant, as shown in  FIG. 9 . The grow tube  100  can be formed of a thin, flexible material. This allows the grow tube  100  to be moved between a flat configuration and a tubular configuration.  FIG. 1  shows the grow tube  100  in the flat configuration. The flat configuration can be used, for example, when storing and/or transporting the grow tube  100 .  FIGS. 7-9  show the grow tube  100  in the tubular configuration. The tubular configuration can be used, for example, when positioning the grow tube  100  around the trunk or stem of a plant (see, e.g.,  FIG. 9 ) to protect the plant. In some embodiments, the grow tube  100  can comprise integrated locking features which allow the grow tube  100  to be quickly and easily moved between the flat and tubular configurations, as further explained below. 
     Referring to  FIGS. 1-3 , the grow tube  100  can comprise a first side  102 , a second side  104 , a first end portion  106 , a second end portion  108 , a first edge portion  110 , and a second edge portion  112 . The grow tube  100  can be folded into the tubular configuration by radially overlapping the first and second edge portions  110 ,  112 , as shown in  FIGS. 7-8 . 
     To releasably secure the first and second edge portions  110 ,  112  in the overlapping configuration, the grow tube can, in some embodiments, include one or more integrally formed locking features. The locking features can comprise a locking element and a receiving element. In some embodiments, the locking element can, for example, be a tab or a flap, and the receiving element can, for example, an opening (which, in some instances, can be defined by a flap or tab) or a slit. For example, in the illustrated embodiment, the grow tube  100  comprises first tabs  114  (which can also be referred to as “receiving elements”) located adjacent to the first edge portion  110  of the grow tube  100  and second tabs  116  (which can also be referred to as “locking elements”) located adjacent to the second edge portion  112  of the grow tube  100 . In the illustrated embodiment, the grow tube  100  has two first tabs  114  and two second tabs  116  (i.e., a first pair of first and second tabs  114 ,  116  disposed adjacent to the first end portion  106  of the grow tube  100  and a second pair of first and second tabs  114 ,  116  disposed adjacent to the second end portion  108  of the grow tube  100 ). 
     In other embodiments, the grow tube  100  can have more or less than two pairs of tabs and/or the tabs can be located at various other locations. For example, in lieu of or in addition to the first and second pairs of tabs  114 ,  116 , the grow tube  100  can comprise a pair of tabs located at an intermediate location between the first and second end portions  106 ,  108  (e.g., proximate to the middle of the grow tube). 
     As shown in  FIGS. 7-8 , each of the first tabs  114  interlocks with a respective second tab  116  to retain the grow tube  100  in the tubular configuration. The grow tube  100  can also be moved from the tubular configuration to the flat configuration by disengaging the first and second tabs  114 ,  116  from each other. In this manner, the grow tube  100  can be moved between the flat and tubular configurations quickly, easily, and without requiring additional fasteners (e.g., zip-ties, rivets, screws, etc.). This also allows the grow tubes  100  to be re-useable. 
     Referring to  FIG. 4 , in some embodiments, the first tabs  114  can be generally semi-circular shaped. The first tabs  114  can be formed by making a generally “C-shaped” cut  118  that extends through the first and second sides  102 ,  104  of the grow tube  100 . As shown in  FIGS. 7-8 , the first tabs  114  can be folded inwardly (e.g., along a first fold line  120 ) such that the first tabs  114  extend away from the second side  104  of the grow tube  100  (or vice versa). Folding the first tabs  114  in this manner creates first openings  122  (which can also be referred to as “receiving openings”), as shown in  FIG. 7 . 
     Referring to  FIG. 6 , in some embodiments, the second tabs  116  can be generally “clamshell” shaped with base or stem portions  124  and main body portions  126  extending from the stem portions  124 . The second tabs  116  have locking surfaces  128  disposed between the stem portions  124  and the main body portions  126 . As best shown in  FIGS. 6-7 , the second tabs  116  can be folded outwardly (e.g., along a second fold line  130 ) such that the second tabs  116  extend outwardly from the first side  102  of the grow tube  100  (or vice versa). Folding the second tabs  116  in this manner creates second openings  132  (defined by the second tabs  116 ), as shown in  FIG. 8 . 
     As shown in  FIGS. 7-8 , the grow tube  100  can be assembled in the tubular configuration by radially overlapping the first and second edge portions  110 ,  112  of the grow tube and interlocking the first tabs  114  with respective second tabs  116 . The first and second tabs  114 ,  116  can be interlocked by inserting the first tabs  114  through respective second opening  132  such that the first tabs  114  extend from the first side  102  of the grow tube to the second side  104  of the grow tube  100  (or vice versa), as shown in  FIG. 8 . The first and second tabs  114 ,  116  are further interlocked by folding the main body portions  126  of the second tabs and inserting the second tabs  116  through respective first openings  122  such that the second tabs  116  extend from the second side  104  of the grow tube  100  to the first side  102  of the grow tube  100  (or vice versa), as shown in  FIG. 7 . 
     Referring still to  FIG. 7 , in some embodiments, the main body portions  126  of the second tabs  116  can be configured so as to be larger than the first openings  122 . As a result, the locking surfaces  128  of the second tabs  116  engage the first side  102  of the grow tube  100  adjacent to respective first openings  122 . Thus, the locking surfaces  128  can prevent the second tabs  116  from inadvertently retracting through the first openings  122  when a radial force is applied to the grow tube  100 . 
     In other embodiments, the first and second tabs  114 ,  116  can comprise various shapes and/or locking features. For example, in some embodiments, the second tabs  116  can be generally “arrow” shaped. In such embodiments, the “head” of the arrow comprises locking surfaces configured to engage the grow tube adjacent to an opening and/or slit (e.g., similar to the locking surfaces  128  of the second tab  116 ) and the “shaft” of the arrow can be configured to extend through an opening or slit (e.g., similar to the stem portion  124  of the second tab  116 ). 
     Forming the first and/or second tabs  114 ,  116  as tabs disposed between the first and second edge portions  110 ,  112  (rather than as projections extending outwardly from an edge) can provide one or more advantages. For example, it can improve interlocking because each tab also forms an opening from receiving another tab. It can also reduce raw material consumption. It can also reduce the likelihood that the tabs will be damaged during shipping and/or storage. 
     Referring again to  FIG. 1 , the grow tube  100  can also comprise one or more anchoring features that are configured to secure the grow tube  100  relative to the ground. For example, the grow tube  100  can include a plurality of anchor-receiving openings  134  (e.g., two in the illustrated embodiment). As shown in  FIG. 5 , the anchor-receiving openings  134  can be formed by making a generally horizontal slit that extends through the first and second sides  102 ,  104  of the grow tube  100 . The anchor-receiving openings  134  can be configured for receiving an anchoring member (e.g., a stake  200 ), as shown in  FIG. 9 . The stake  200  can be used, for example, to secure the grow tube  100  relative to a tree  202  and the ground  204 . 
     In other embodiments, the grow tube  100  can comprise more or less than two (e.g., 1 or 3-6) anchor-receiving openings  134  and/or the location of the anchor-receiving openings  134  on the grow tube  100  can be altered. 
     In some embodiments, the grow tube  100  can comprise a vent. The vent can be configured to allow airflow through the grow tube  100  while also reducing the likelihood that materials (e.g., chemicals such as pesticide and herbicide) will enter the grow tube  100  through the vent and contact a plant disposed within the grow tube. For example,  FIGS. 10-12  show the grow tube  100  with an optional vent  136 . As shown in  FIG. 12 , the vent  136  comprises a flap  138  and an opening  140 . The opening  140  of the vent  136  is configured to allow airflow into and/or through the grow tube  100 , and the flap  138  of the vent  136  is configured to reduce the likelihood that materials (e.g., chemicals such as pesticide and herbicide) will enter the grow tube  100  through the opening  140  and contact a plant disposed within the grow tube. 
     The vent  136  allows air to flow into the grow tube  100  through the opening  140  of the vent  136 . In some instances, the vent  136  can create an updraft of airflow through the interior (i.e., the second side  104 ) of the grow tube  100  as air flows through the opening  140  and upwardly toward the first end portion  106  of the grow tube  100 . Also, when chemicals are sprayed onto the first side  102  of the grow tube  100 , the flap  138  of the vent  136  partially covers the opening  140  of the vent  136  and can prevent the chemicals from entering the grow tube  100  through the opening  140  (particularly when chemicals are sprayed from a height above the vent  136  and below the first end portion  106  of the grow tube  100 ). As a result, the chemicals will run down the grow tube  100  and, rather than running into the grow tube  100  through the opening  140 , the chemicals will drip off the tip of the flap  138  onto the ground at a location outside of the grow tube  100 . 
     Configuring the vent  136  with the flap  138  (rather than just an uncovered opening) can provide one or more advantages. For example, the flap  138  allows air flow through the opening  140  but also prevents or reduces the likelihood that chemical spray on or around the grow tube  100  will inadvertently enter the interior of the grow tube  100  through the opening  140  and contact a plant disposed within the grow tube. 
     Although the flap  138  of the vent  136  is shown extending radially outwardly in  FIGS. 11 and 12 , the flap  138  can, in some instances, extend radially inwardly. A radially inwardly extending flap can be configured to direct material onto the ground at a location spaced apart from the plant. 
     In the illustrated embodiment, the vent  136  is configured in a “V” or triangle shape. Configuring the flap  138  in this shape can provide one or more advantages. For example, the V-shaped flap  138  acts like a funnel that can direct chemical spray away from the opening  140 . In other embodiments, the vent  136  can have another shape (e.g., rectangular, semi-circular, semi-ovular, W-shaped, etc.), each of which has particular advantages. 
     Although the illustrated embodiment depicts only one vent, in other embodiments, the grow tube can include more than one vent. For example, in some embodiments, the grow tube  100  can have 2-10 vents. 
     In the illustrated embodiment, the vent  136  is disposed generally adjacent to the second end portion  108  of the grow tube  100 . This location can provide particular advantages such as providing an updraft airflow direction through the grow tube. It can also reduce the chance that chemical spray will enter the grow tube  100  through the vent  136  because sources of chemical spray are typically located above the location of the vent  136 . 
     In other embodiments, the vent  136  can be disposed at various locations on the grow tube  100 . For example, the vent can be disposed closer to the first end portion  106  of the grow tube  100  and/or moved closer toward either the first or second edge portion of the grow tube than depicted in the illustrated embodiment. 
     In some embodiments, a grow tube can comprise a vent (e.g., the vent  136 ) but can omit other features of the grow tube  100  (e.g., the first and/or second tabs  114 ,  116 ). In such, embodiments, the grow tube may include one or more openings or slits and/or one or more coupling members configured to secure the grow tube in a tubular configuration. For example, the coupling member can be a fastener (e.g., a tip-tie, rivet, screw, etc.), a stake or rod, or other means for coupling. The grow tube can be coupled together by overlapping the edges of the grow tube and inserting a stake through the openings or slits of the grow tube to retain the grow tube in the tubular configuration. 
     In some embodiments, the grow tube  100  can include an adjustment mechanism that allows the diameter of the grow tube  100  in the tubular configuration to be adjusted to a desired size. For example,  FIG. 13  shows the grow tube  100  with an optional adjustment mechanism  142 . In the illustrated embodiment, the adjustment mechanism  142  comprises a plurality of first tabs  114  adjacent to each end portion  106 ,  108  of the grow tube  100 . Specifically, the grow tube  100  includes three first tabs  114   a ,  114   b ,  114   c  adjacent to the first end portion  106  of the grow tube  100  and three first tabs  114   d ,  114   e ,  114   f  adjacent to the second end portion  108  of the grow tube  100 . In other embodiments, the grow tube can have more or less than three (e.g., 2-5) first tabs  114  adjacent to each end portion of the grow tube. 
     As shown in  FIGS. 15-17 , the adjustment mechanism  142  ( FIG. 13 ) allows the grow tube  100  to be adjusted to various diameters. For example,  FIG. 15  shows the grow tube  100  in a first tubular configuration in which the first tabs  114   a ,  114   d  are interlocked with respective second tabs  116 .  FIG. 16  shows the grow tube  100  in a second tubular configuration in which the first tabs  114   b ,  114   e  are interlocked with respective second tabs  116 .  FIG. 17  shows the grow tube  100  in a third tubular configuration in which the first tabs  114   c ,  114   f  are interlocked with respective second tabs  116 . The grow tube  100  has a larger diameter in the first tubular configuration ( FIG. 15 ) than in the second configuration ( FIG. 16 ) and the third configuration ( FIG. 17 ), and the grow tube  100  has a larger diameter in the second configuration than in the third configuration. 
     In other embodiments, the adjustment mechanism can comprise only two first tabs  114  (i.e., one first tab adjacent to the first end portion  106  of the grow tube  100  and another first tab  114  adjacent to the second end portion  108  of the grow tube  100 , see, e.g.,  FIG. 1 ), a first plurality of second tabs  116  (e.g., 2-5 second tabs) disposed adjacent to the first end portion  106  of the grow tube  100  and a plurality of second tabs  116  (e.g., 2-5 second tabs) disposed adjacent to the second end portion  108  of the grow tube  100 . 
     In yet other embodiments, the adjustment mechanism can comprise a first plurality of first tabs  114  and a first plurality of second tabs  116  disposed adjacent to the first end portion  106  of the grow tube  100  and a second plurality of first tabs  114  and a second plurality of second tabs  116  disposed adjacent to the second end portion  108  of the grow tube  100 . Such embodiments can, for example, provide a more secure connection between the first and second edge portions  110 ,  112 . 
     In some embodiments, the grow tube  100  can comprise a vent and an adjustment mechanism. For example,  FIG. 14  shows the grow tube  100  with the vent  136  and the adjustment mechanism  142 . 
       FIG. 18  shows a grow tube  300 , according to another embodiment. The grow tube  300  can comprise a first side  302 , a second side (not shown), a first end portion  304 , a second end portion  306 , a first edge portion  308 , and a second edge portion  310 . Although not shown, the grow tube  300  can be folded into the tubular configuration by radially overlapping the first and second edge portions  308 ,  310  (e.g., similar to the manner shown in  FIGS. 7-8  with the grow tube  100 ). 
     The grow tube  300  can further comprise integrally formed locking features to retain the grow tube in the tubular configuration. For example, the locking features of the grow tube  300  comprise receiving elements (e.g., openings  312 ) and locking elements (e.g., locking tabs  314 ). The locking tabs  314  can be inserted through the openings  312  and can engage the grow tube  300  adjacent to the openings  312  (e.g., similar to the manner in which the second tabs  116  engage the grow tube  100  adjacent to the openings  122 , as shown in  FIGS. 7-8 ). 
     In the illustrated embodiment, the openings  312  of the grow tube  300  comprise a circular shape. However, in other embodiments, the openings  312  can comprise various other shapes such as ovular, rectangular, etc. 
     In the illustrated embodiment, the locking tabs  314  of the grow tube  300  comprise a clamshell shape. However, in other embodiments, the locking tabs  314  can comprise various other shapes such as arrow shaped or other shapes comprising one or more locking surfaces. 
     In some embodiments, the grow tube  300  can comprise an adjustment mechanism comprising a plurality of openings  312  and/or a plurality of locking tabs  314  (e.g., similar to the adjustment mechanism  142  of the grow tube  100  shown in  FIG. 13 ). Additionally or alternatively, in some embodiments, the grow tube  300  can comprise one or more vents (e.g., similar to the vent  136  of the grow tube  100 ) and/or one or more anchor-receiving openings (e.g., similar to the anchor-receiving openings  134  of the grow tube  100 ). 
       FIG. 19  shows a grow tube  400 , according to yet another embodiment. The grow tube  400  can comprise a first side  402 , a second side (not shown), a first end portion  404 , a second end portion  406 , a first edge portion  408 , and a second edge portion  410 . Although not shown, the grow tube  400  can be folded into the tubular configuration by radially overlapping the first and second edge portions  408 ,  410  (e.g., similar to the manner shown in  FIGS. 7-8  with the grow tube  100 ). 
     The grow tube  400  can further comprise integrally formed locking features to retain the grow tube in the tubular configuration. For example, the locking features of the grow tube  400  comprise receiving elements (e.g., slits  412 ) and locking elements (e.g., locking tabs  414 ). The locking tabs  414  can be inserted through the slits  412  and engage the grow tube  400  adjacent to the slits  412  (e.g., similar to the manner in which the second tabs  116  engage the grow tube  100  adjacent to the openings  122 , as shown in  FIGS. 7-8 ). 
     In the illustrated embodiment, the locking tabs  414  of the grow tube  400  comprise a clamshell shape. However, in other embodiments, the locking tabs  414  can comprise various other shapes such as arrow shaped or other shapes comprising one or more locking surfaces. 
     In some embodiments, the grow tube  400  can comprise an adjustment mechanism comprising a plurality of slits  412  and/or a plurality of locking tabs  414  (e.g., similar to the adjustment mechanism  142  of the grow tube  100  shown in  FIG. 13 ). Additionally or alternatively, in some embodiments, the grow tube  400  can comprise one or more vents (e.g., similar to the vent  136  of the grow tube  100 ) and/or one or more anchor-receiving openings (e.g., similar to the anchor-receiving openings  134  of the grow tube  100 ). 
       FIGS. 20-22  shows a grow tube  500 , according to yet another embodiment. Referring to  FIG. 20 , the grow tube  500  can comprise a first side  502 , a second side (not shown), a first end portion  504 , a second end portion  506 , a first edge portion  508 , and a second edge portion  510 . 
     The grow tube  500  can further comprise integrally formed locking features to retain the grow tube in the tubular configuration. For example, the locking features of the grow tube  300  comprise receiving elements (e.g., receiving tabs  512   a ,  512   b , collectively referred to as “the receiving tabs  512 ”) and locking elements (e.g., locking tabs  514   a ,  514   b , collectively referred to as “the locking tabs  514 ”). As shown in  FIG. 20 , the receiving tabs  512  are located diagonally relative to each other (e.g., a first receiving tab  512   a  is disposed at the corner formed by the first end portion  504  and the first edge portion  508  and a second receiving tab  512   b  is disposed at the corner formed by the second end portion  506  and the second edge portion  510 ). The locking tabs  514  are also located diagonally relative to each other (e.g., a first locking tab  514   a  is disposed at the corner formed by the first end portion  504  and the second edge portion  510  and a second locking tab  514   b  is disposed at the corner formed by the second end portion  506  and the first edge portion  508 ). The locking tabs  314  can be inserted through the openings  312 . The locking tabs  314  can engage the grow tube  300  adjacent to the openings  312  (e.g., similar to the manner in which the second tabs  116  engage the grow tube  100  as shown in  FIGS. 7-8 ). 
     Configuring the grow tube  500  with the receiving tabs  512  located diagonally from each other with the locking tabs  514  located diagonally relative to each other allows the grow tube to be folded into a plurality of tubular configurations, as shown in  FIGS. 21-22 . 
     For example, as shown in  FIG. 21 , the grow tube  500  can be folded into a first tubular configuration by radially overlapping the first and second edge portions  508 ,  510 , interlocking the first receiving tab  512   a  with the first locking tab  514   a , and interlocking the second receiving tab  512   b  with the second locking tab  514   b . Folding the grow tube  500  in this manner creates a relatively tall, narrow tubular configuration. 
       FIG. 22  shows the grow tube folded into a second tubular configuration by radially overlapping the first and second end portions  504 ,  516 , interlocking the first receiving tab  512   a  with the second locking tab  514   b , and interlocking the first locking tab  514   a  with the second receiving tab  512   b . Folding the grow tube  500  in this manner creates a relatively wide, short tubular configuration. 
     In the illustrated embodiment, the receiving tabs  512  of the grow tube  500  comprise a semi-circular shape. However, in other embodiments, the receiving tabs  512  can comprise various other shapes such as ovular, rectangular, etc. In yet other embodiments, the grow tube  500  can comprise openings and/or slits in lieu of the tabs  512 . 
     In the illustrated embodiment, the locking tabs  514  of the grow tube  500  comprise a clamshell shape. However, in other embodiments, the locking tabs  514  can comprise various other shapes such as arrow shaped or other shapes comprising a locking surface. 
     In some embodiments, the grow tube  500  can comprise an adjustment mechanism comprising a plurality of receiving tabs  512  and/or a plurality of locking tabs  514 . In some embodiments, the grow tube  500  can have a plurality of tabs  512 ,  514  extending in a row along the end portions  504 ,  506  (i.e., horizontally in the orientation depicted in  FIG. 20 ), which allows the diameter of the grow to be adjusted when the grow tube is in the first tubular configuration (e.g.,  FIG. 21 ). Additionally or alternatively, the grow tube  500  can have a plurality of tabs  512 ,  514  extending in a column along the edge portions  508 ,  510  (i.e., vertically in the orientation depicted in  FIG. 20 ), which allows the diameter of the grow tube  500  to be adjusted when the grow tube is in the second tubular configuration. 
     In some embodiments, the grow tube  500  can comprise one or more vents (e.g., similar to the vent  136  of the grow tube  100 ) and/or one or more anchor-receiving openings (e.g., similar to the anchor-receiving openings  134  of the grow tube  100 ). 
     The grow tubes described herein can be formed of various materials. For example, the grow tubes can be formed of various polymeric materials such as polyethylene and/or polypropylene. It is also contemplated that the grow tubes can be formed of various other materials including metals (e.g., steel) or plant-based products (e.g., cardboard, fiberboard, bioplastic, etc.). 
     In some embodiments, the grow tube can be formed such that it is biased to the tubular configuration. This can be accomplished, for example, by cutting the grow tube from a roll of material (as opposed to a sheet of material). In this manner, the grow tube will tend to assume the tubular configuration. In such configurations, the grow tube can be retained in the flat configuration (e.g., for forming the openings, vents, etc. and/or for transporting or storing) by strapping, a box, and/or other holding mechanism. Accordingly, as used herein, the term “flat configuration” means that the edge portions of the grow tube are released from each other and the grow tube is capable of being flattened to a single layer (see, e.g.,  FIG. 1 ), not necessarily that the grow tube is flat without any external forces applied thereto. Thus, the tubular configuration can also be referred to as a “secured configuration,” and the flat configuration can also be referred to as an “unsecured configuration.” 
     In some embodiments, the grow tube can also be formed from a single-wall material (as opposed to multi-layer materials and/or corrugated materials). This allows the grow tube to be relatively inexpensive, easy to manufacture, and/or reduces raw material consumption. In other embodiments, the grow tube can be formed from multi-layer material and/or corrugated material. 
     Configuring the grow tube so that it can be moved between the flat and tubular configurations and/or from a single-wall material also provides advantages for transporting and storing the grow tubes. For example, the grow tubes can be transported and/or stored in the flat configuration. This allows more grow tubes to be transported and/or stored per unit volume than grow tubes that are always in a tubular configuration or that are formed of a multi-layer material. 
     The grow tubes disclosed herein can be configured to accommodate various types of plants. For example, in some embodiments, the grow tubes can be configured for use with hazelnut trees and/or grape vines. 
     The structural features described herein, with regard to any example, can be used separately and/or combined with other structural features described in any one or more of the other examples. For example, a grow tube can comprise the vent  136 , but omit one or more other features such as the first and second tabs  114 ,  116  and/or the anchor-receiving openings  134  (or vice versa). As another example, the grow tube  300 ,  400 , and/or  500  can comprise the vent  136  of the grow tube  100 . In another example, the grow tube  100  can comprise the openings  312  of the grow tube  300  rather than the first tabs  114  (or vice versa). In yet another example, the grow tube  100  can comprise the slits  412  of the grow tube  400  rather than the first tabs  114  (vice versa). 
     In view of the many possible embodiments to which the principles of the disclosure may be applied, it should be recognized that the illustrated embodiments are only examples and should not be taken as limiting the scope of the claims. Rather, the scope of the claimed subject matter is defined by the following claims and their equivalents.
