Knowing how to grow a Euonymus plant is essential for adding excellent texture to your garden. The good news is it’s actually pretty easy.
This type of shrub comes in 175 different varieties which include everything from dwarf shrubs up to 15 feet tall trees and even climbing vines.
They are favoured for their attractive foliage and their stunning autumn color. Some of these plants even have unique fruit and seed pods.
They are available in a huge range of colour and size. You can get them as deciduous plants or evergreens.
Whether you need them for
This shrub will have you covered.
Pruning the tips can be done anytime to keep its shape and size but I wouldn’t cut the plant back hard until it is dormant. Your plant will get very stressed if you cut it back hard when it is still in its growing stage.
In our Canadian Hardiness zone 6a the plant should be dormant from the end of November until the beginning of April. If you want to rejuvenate your bush, you can cut it back to about a foot or so. It will take a few years to reach maturity again but it will be worth it. Your shrub will look like new again.
There are many types of shrubs to choose from. Here are a few I have in my landscape and offer in my plant nursery:
These are great choices for hedges, borders, stand alone specimens, and more with year round interest. Which one is your favourite?
The main 2 problems with the Euonymus plant are scale insects and crown gall. There are other pests and diseases to watch for but they are less severe.
Scale Insects – They are sap sucking insects that wear a hard waxy coating for protection. They resemble small bumps on the stems of plants that rarely move once they become adults. If the infestation becomes bad enough they will kill the plant.
They are difficult to control but keeping the plant healthy and well watered during drought will help prevent them. If it is just a small infestation rub the stems with your finger or a small brush that has been dipped in rubbing alcohol. You can also prune out any heavy infected branches and dispose of them into the garbage. You can also use horticulture oil.
Besides scale insects you need to watch for:
Crown Gall – This is a soil inhabitant bacterium that interferes with the water and nutrients that the plant needs to grow. It can stunt the plants growth; cause leaves to turn yellow and fall off and stems to die back. The plant will develop rough round circular masses with a corky texture.
There isn’t a cure for crown gall but branches that have been affected can be pruned out and disposed of. A plant can survive for several years with this disease but if it gets really bad you may have to dispose of the plant. The soil around where the plant was will still be infected with the disease for 2-3 years. If you want to plant something in place of the removed shrub, pick something that won’t be affected by gall. Boxwoods, barberries and holly are good choices.
Other diseases that might affect your plant are:
There are many ways to propagate the Euonymus plant. It depends on the variety on which one you want to do. However, they can all be propagated through stem cuttings.
The easiest way to propagate is by stem cuttings. Take a cutting about 4” long put it in a pot of potting soil, wet down the soil and cutting thoroughly and cover with a white plastic bag. Check it about twice a week to make sure it is kept moist and in a few weeks it should have roots. For more on rooting cuttings check out my propagation article.
You can also propagate them through:
