Planting and Growing Euonymus

Euonymus is a low maintenance, easy to grow, shrub or small tree. Best grown in sun or partial shade in any reasonable, well drained, garden soil. Most species will happily grow in difficult clay or chalky soils, north-facing positions and will even tolerate drought once established. However, they dislike waterlogged conditions. Variegated evergreen forms need some sun to maintain their variegation.

Plant outside in early autumn or spring. Container grown plants can be planted out at any reasonable time of year.

E. japonicus is tolerant of pollution and a good choice for coastal gardens.

Taking Care of Euonymus

Water thoroughly during dry weather until well established.

Pruning Euonymus

Pruning is not necessary, except to tidy-up the plants and remove any damaged wood or overlong shoots. Most species can be cut back hard in the spring, should they become unkempt or too large.

Trim hedges in May and early autumn. Cut out any plain green reverted shoots on variegated forms.

Pests and Diseases

Susceptible to attack by caterpillars, aphids, euonymus scale and vine weevil.

The leaves can be affected by powdery mildews and a leaf spot.

Propagating Euonymus

Plant semi-ripe cuttings in summer or take heeled hard-wood cuttings in autumn, and root in a cold frame. Alternatively layer low lying branches in early summer.

Pot-up sections of creeping varieties that have self-rooted.

Seed of E. europaeus can be sown in March under cover.
