During the growing season in spring and summer, use a diluted, balanced fertilizer to nourish your plant. Fertilize every 4-6 weeks for best results.

Pruning Methods ✂️

Regular pruning helps maintain the health of your Euphorbia. Remove any dead or damaged stems, ideally in early spring before new growth begins.

Ongoing Care 🛡️
