Send your water to a lab to be tested, if you can. With good, "soft" water, you'll be able to add any nutrients your plants need for their optimal growing season. With "hard" water, you may need to use reverse osmosis methods to filter out any unwanted heavy metals present in your water. You can also use a dissolved solids meter to check your water regularly. This is also called an electrical conductivity (EC) or parts per million (PPM) meter. Calcium and magnesium carbonates are quite common ingredients in both tap water and well water. Each are necessary nutrients for plant growth, but in limited amounts. Knowing how much of these elements are present in your water determines how much, if any, you need to add. The essential nutrients used include calcium nitrate, potassium sulphate, potassium nitrate, mono potassium phosphate, and magnesium sulphate. Each element involved in these nutrients provides a different benefit. Hydrogen forms water by combining with the oxygen. Nitrogen and sulfur are essential to the supply of amino acids and proteins. Phosphorus is used in photosynthesis and overall growth. Potassium and magnesium act as catalysts in the creation of starches and sugars. Magnesium and nitrogen also play a role in the production of chlorophyll. Calcium is a part of the make-up of cell walls, and plays a role in the growth of cells. Micronutrients, also called trace elements, are also essential, but they are only required in very small amounts. These elements effect growth, reproduction, and the effect that other nutrients have on the plant. Micronutrients used include boron, chlorine, copper, iron, manganese, sodium, zinc, molybdenum, nickel, cobalt, and silicon. There should be at least 10 trace elements present in your nutrient mix. The best temperature for plants is tepid: neither warm nor cold to the touch. If your solution is too cold, your plants won't germinate. They may mold or rot. If your solution is too hot, your plants might die from stress or oxygen deficiency. The optimal temperature for water is between 65 degrees (18 C) and 80 degrees (27 C). Plants grown in colder climates will thrive in cooler water, while plants grown in warmer regions prefer warmer water. When you add new water to your reservoir, make sure it's approximately the same temperature as the existing reservoir water. You can use a pH meter to check your balance. You want your pH balance to be between 5.5 and 7.0. Your water's pH balance ultimately impacts the plants' ability to take in nutrients. It's normal for pH balances to wander up and down. The balance will naturally change as elements are absorbed by the plants. Avoid adding too many chemicals as a reaction to the varying pH balance. If you have poor quality growing medium, this may affect the stability of your pH balance. Most municipal water systems raise the pH level of their water by adding calcium carbonate. The average pH balance of city water is often as high as 8.0. Remember that pH measuring kits will show different levels in different temperatures. Check your water temperature before adding chemicals to your water.

Measure from the point where the mattress touches the box spring to the top of the mattress. Add 3 inches (7.6 cm) to that number. A 12-inch (30.5-cm) deep mattress will have a drop length of 15 inches (31 cm). Multiply the drop length by 2. A drop length of 15 inches (31 cm) gives you 30 inches (76. 2 cm). Add the sum to the width of the mattress. A 54-inch (137-cm) wide mattress results in 84 inches (213.4 cm). Multiply the drop length by 2. A drop length of 15 inches (31 cm) gives you 30 inches (76.2 cm). Add the sum to the mattress length. If your mattress is 75 inches (109.5 cm) long, your total is 105 inches (266.7 cm).

One-sentence summary -- Measure the length and width of your mattress. Calculate the drop length. Determine the comforter's width. Calculate the comforter's length.

The "vi" part of this command selects the Vim text editor as the program to use. You'll replace "filename" with the name you wish to assign to your new file. For a file named "tamins", for example, you'd type vi tamins.txt. If your current directory has a file by the same name, this command will instead open that file. This will create your new file and open it in the Vim editor. You should see a blank Terminal window with a tilde (~) on each line, as well as your text file's name at the bottom of the window. Doing so will place your document in "Insert" mode, wherein you can enter text as needed. You should see -- INSERT -- pop up at the bottom of the window when you press the I key. It's typically in the upper-left corner of your computer's keyboard. This key will stop the insert mode. This key will place Vim in "Command" mode. You should see a cursor appear at the bottom of the window. This command will save your document as it currently is. Doing so will quit out of Vim and return you to Terminal's main interface. Your text file is now in your specified directory. You can check for the text file by typing ls into Terminal and pressing Enter and then looking for the file's name. You can also type :wq to save and quit in one command. Just as you did to create the file, you'll type vi filename.txt to open the file. This time when you open the file, you should see any saved changes that you made.

One-sentence summary -- Type vi filename.txt into Terminal. Press Enter. Press your computer's i key. Press the Esc key. Press the : (colon) key. Type :w into Terminal and press Enter. Type :q into Terminal and press Enter. Reopen the file from the Terminal window.

Foliar feed is a liquid plant food that is sprayed directly onto the leaves. In addition to providing the plant with nutrients, it also helps protect against disease. Begin feeding your Midnight Blue rose bush as soon as it's established in the spring (about 3-4 weeks after planting, or as soon as you see new growth on an older plant). Feed it a couple more times during the growing season once after the first blooms form and then a final time around midsummer. Water your rose bush before giving it fertilizer. Do not give fertilizer to a thirsty plant. Follow the dosage guidelines on the product packaging. Excess doses can damage the plant. You can opt to sprinkle a slow-release granule feed on top of the soil instead. The nutrients will be taken down to the roots the next few times you water the plant. Give container roses a feeding every 2-3 weeks through the spring and summer with a foliar feed or granule feed. Check the top inch of soil for moisture several times a week, and if it feels dry, saturate the soil with water. Ensure good drainage by putting the container up on feet. A layer of gravel at the bottom of the container can also help with drainage. If the rose outgrows the container it will need to be repotted into a larger one. Look for matted roots at the surface of the soil or roots growing out through the drainage holes. Consider hand-pulling the weeds, as this is the gentlest and safest way to remove weeds without damaging your rose bush. You can also put mulch down around your plant to help stop weed growth. Try to avoid hoeing weeds around your roses, as rose roots tend to be close to the soil surface and can be damaged by the hoe. Avoid chemical weed killers as well, since these can also harm your rose bush.
