How often should I fertilize my pencil tree (Euphorbia tirucalli)?
Answer
Minimal nutritional intervention is required. Pencil trees should be fed only during their growing season (March through September). A balanced, organic houseplant food, fed at half strength, every four weeks during the growing period is enough for pencil tree.
