![]() In these conditions, the hosta can be successfully grown for many years until the tree becomes very large. As a result, the plant will be able to quickly take up free space and compete with the roots of the tree. Do not touch roots more than an inch thick.įor planting, it is better to choose hostas with a strong rhizome. Use a sharp knife or scissors to cut all of the tree’s roots. Then start digging, using a good quality, sharp shovel.Īccording to scientific research, many trees can withstand 10% root system damage without serious consequences.ĭig a hole twice the size of the root ball. Step back at least 1 foot (30 cm) from the trunk for young trees and at least 3 feet for larger trees. Remember a simple rule: the younger the tree, the easier it will be to grow plants under it. Under these conditions, hostas will need special care, which we will talk about later. Oak and conifers are the trees under which you can successfully grow hostas. The hostas will grow quite well for a few years. You can dig a hole and trim the roots of the maple and then plant the hostas there. However, if the maple is mature and of considerable size, hostas may not grow well under it. You can successfully grow hostas under these trees for many years without harming them. Red and Japanese maples may be an exception. Therefore, I do not recommend planting hostas under these trees. However, the roots of some trees are less aggressive and other plants can be grown under them.Īll maple species, and especially silver maple, have very fibrous and dense roots. Most trees have a shallow root system, and almost all of their roots are 14-16 inches (35-40 cm) deep. If you follow my recommendations, you may be successful. ![]() Under some trees, hostas grow better than under others, but in general, it is possible. The hosta is able to grow near the roots of most trees. This is especially true of pine, which has a suitable crown shape. There are many examples of the successful cultivation of hostas under coniferous plants. However, growing hostas in such conditions requires additional care. The superficial roots of oak do not interfere with the growth of other plants around. Walnut releases a toxin (juglone) that can cause significant damage not only to hostas but also to many other plants. In addition, these plants quickly dry out the soil around them. Willows have thin roots that form a dense carpet. ![]() Maple roots are very aggressive and it is almost impossible to grow other plants under their canopy.
