Both deciduous and evergreen varieties of Euonymus bushes, often known as spindle plants or trees, are available. Euonymus bushes belong to the genus Euonymus. The leaves and fruits of deciduous varieties are often brightly coloured in the autumn. The most common kinds of trees and shrubs are evergreens that have variegated leaves. In the spring, euonymus has blooms that are quite unimportant. If evergreen varieties are neglected for an extended period of time without proper care, they may need severe trimming to stimulate new growth. When it comes to evergreen kinds, yearly pruning is the most effective way to shape and regenerate growth.
About Evergreen Euonymus
The Japanese spindle, also known as Euonymus japonicus, may grow up to a height of 20 feet. According to Missouri Botanical Garden, this species has glossy, oval leaves that range in colour from light to dark green and is hardy in plant hardiness zones 6 through 9 according to the United States Department of Agriculture. There are a lot of different cultivars out there. The growth shape of a cultivar may range from narrow and compact to spreading or mounding, depending on the desired effect.
The Gold Spot plant, also known as Euonymus japonicus ‘Aureovariegatus,’ has leaves that are green on the outside and brilliant yellow in the middle. The Green Spire (Euonymus japonicus ‘Green Spire’) has a growth habit that is columnar and thin, and its leaves have a dark green colour. The leaves of the Silver King (Euonymus japonicus ‘Silver King’) have a silvery-white border that runs the length of the leaf. Shrubs should be pruned in the spring, after they have finished blooming, in order to retain the ideal shape and to eliminate green shoots from variegated varieties. Growing older bushes have the potential to be trained into tiny trees.
About Deciduous Euonymus
There are two types of burning bushes native to the United States: the bursting heart burning bush, often known as the strawberry bush (Euonymus americanus), which can survive in USDA zones 6 through 9, and the western burning bush, which may be grown in USDA zones 3 through 9. Both feature vibrant reddish-orange fruits in the autumn. Both the winterberry euonymus (Euonymus bungeanus) and the flaming bush euonymus (Euonymus alatus) are euonymous species that are indigenous to China. Leaves become crimson in autumn. According to Missouri Botanical Garden, both species may be found growing in USDA zones 4 through 8.
Some species of deciduous euonymus grow more slowly and, as a result, may not need as much trimming. The height of these plants ranges anywhere from four to six feet for the strawberry bush to around eleven feet for the winged burning bush and twenty feet for the winterberry euonymus. You should plan to do light maintenance pruning in the late winter or early spring, and more extensive pruning in the late spring or early summer.
Pruning and Trimming Euonymus Bushes
It is recommended by Hawks Landscape that if the development of deciduous euonymus shrubs gets crowded, the plants should be opened up in the late winter or early spring before the leaves appear. During this time, the branching structure may still be seen clearly. Take off any branches that are broken or damaged, any branches that are crossing one other, and any branches that are too close together. Always use sharp pruning shears that have been cleaned after each cut with rubbing alcohol or a solution that consists of one part household bleach to ten parts water.
Always keep an eye on your evergreen variegated euonymus bushes throughout the year to remove any branches that are solid green. In the event that they mature, it is probable that the variegated shape will be lost forever. When working with fast-growing cultivars, frequent pruning in the spring and summer helps establish the appropriate form and size of the plant.
After the euonymus bushes have finished blooming in late spring or early summer, the growth should be pruned down so that they form a hedge. When it comes to areas where the presence of autumn fruits is essential, prune judiciously by hand with pruning shears rather than using loppers or electric trimmers in order to keep the foliage in its autumnal hue. In areas of the euonymus that have not been maintained on a routine basis, the stems should be pruned to a low, fundamental framework in the late winter or early spring. This will reduce the amount of blooming and fruiting that happens during that year due to the fact that flowering occurs on old wood.
