Euonymus shrubs are a versatile addition to any garden, providing year-round interest with their deciduous or evergreen foliage. 

To encourage new growth and improve the health and appearance of the plant, you will need to trim the branches every once in the while.

Most euonymus species are ready for some barbering during late winter and early spring. However, for several varieties that bloom in spring, you should save the date until after flowering and it should be immediately, don’t hold off for too long.

When deciding the timing, consider your goals for pruning.

Maintenance pruning, which involves removing dead or damaged material and giving the plant a light tidy, is best done in late winter or early spring. 

However, if you have a hedge or formal shrub that requires shaping, additional pruning in summer may be necessary. 

It’s important to avoid pruning too late in the season, as this can expose new growth to winter frosts.

Deciduous types of Euonymus, such as the European spindle and E. alata, generally require minimal pruning. 

These shrubs have well-formed shapes and coexist harmoniously with other plants in beds or borders. 

While they can be used for hedging, they are usually more suited for informal hedgerows. 

If pruning is necessary, it’s typically limited to removing dead or damaged material and correcting any wayward branches.

Evergreen Euonymus

Evergreen Euonymus, like E. fortunei and E. japonicus, often exhibit pleasing natural forms and may not require much shaping. 

Remember to select a variety that suits the available space, as some can grow larger than others. 

Depending on your preferences, there are three types of pruning you can consider:

1) Maintenance Pruning

In a more naturalistic scheme, maintenance pruning involves removing dead, damaged, or unsightly material in late winter or early spring. 

While not always necessary, light trimming can encourage bushiness and stimulate new growth. 

It can also help control the size and shape of the plant, giving it a more balanced appearance.

2) Pruning for Hedging or Topiary Forms

If you’re growing Euonymus for a formal hedge or topiary form, more precise pruning is required. 

Loose and informal hedgerows may only need occasional trimming to maintain their shape. 

However, for a neat, formal appearance, accurate pruning is necessary to shape and control growth. 

It’s recommended to use secateurs or loppers instead of hedge trimmers to avoid unsightly leaf cuts.

3) Renovation Pruning

While not a common practice, renovation pruning can rejuvenate mature Euonymus shrubs or aging hedges. This involves cutting back evergreen Euonymus by 30-50% to promote lush and bushy growth. 

I know this seems too much but once the plant recovers, you will get much more vibrant and healthier bushes. Still, it might take some time for the process to manifest.

  • Remember: this drastic pruning method may not be suitable for all Euonymus varieties. Familiarize yourself with the characteristics of your specific Euonymus before opting for renovation pruning.
