Ferns can be multiplied also by means of division of older plants and tissue culture. Ferns with below-ground, creeping rhizomes can form large masses as they become established since new growth is constantly developed during the growing season. Any of these can become invasive. Ferns with a crown or clump of clustered stems produce only new growth from this main area so they are more restrained from expanding. If it becomes necessary to move or divide either of these types, you need to remember that the clustered type does best when moved during the dormant period and the rhizome type can be moved spring or fall.
Most ferns live in rocks, trees, or very shallow soils that are loose and drain rapidly.
Ferns like to be moist but not waterlogged. Daily misting your plants is not a good idea either, as it can cause crown rot. Make sure to water deeply only when it is necessary for good plant health. The best way to do this is to check soil conditions before making the decision of whether water is needed. You can use a time- released type fertilizer or add fertilizer to your water once a month during the active growing season.
