Information On How To Prune Roots On Houseplants

Sometimes, to cultivate plants for indoor use, you end up doing some root cutting. This is an acceptable way of dividing plants to either bring indoors, or to divide those that are pot bound so you can separate them into new pots. Whenever you have potted plants in your home, you end up with the issue of rootbound plants. This is when the pot is full of mostly roots and very little dirt is left. This happens as the plant matures. Eventually, the roots grow to the shape of the pot and you end up with a pot shaped clump of roots.

How to Prune Roots on Rootbound Plants

Most plants will tolerate simple root pruning. You will want to do root cutting on the thread roots, not the tap roots. The tap roots will be the larger roots and the thread roots will be the small roots that grow off the tap roots. All you have to do is take the plant and cut the tap roots apart, removing no more than one-third of the thread roots in the process. You shouldn't shorten the tap roots at all during this process, but using clippers to trim the thread roots is acceptable. Also, prune roots that are dead looking away. Root pruning is nothing more than stunting a plant for repotting. You don't want the pot to have a huge clump of roots in it because this means the plant will not get much nourishment from the dirt. This is because less soil will fit in the pot. Root cutting keeps the plant smaller and, therefore, in a smaller pot longer. Rootbound plants will eventually die. If you start seeing that the leaves are turning yellow or the whole plant is wilting, check the root system in the pot. Chances are you have one of those rootbound plants and will have to perform some root pruning to help this plant survive. Keep in mind that whenever you cut roots, you need to be careful. When you cut the roots, you are injuring them, and some plants that are sickly or unhealthy cannot handle that. This means that if you have to cut roots to repot your plants, be sure to do it very selectively and carefully. Pruning roots is a normal part of helping your houseplants grow. You just have to be careful whenever handling the root structure of any plant, and be sure to give plenty of water and fertilizer, if recommended in the plant instructions, after you do root pruning on any of your plants.
