leaf drop on Euphorbia Tirucalli
Quick answer
If your Euphorbia Tirucalli has leaf drop, the most likely cause is: Euphorbia tirucalli (pencil tree) maintains photosynthetic epidermis on stems up to 6cm diameter through unique bark dilatation. Expansion cracks (vertical epidermal ruptures) form between stomatal zones, delaying periderm formation to prolong stem photosynthesis. This adaptation requires stable environmental conditions—sudden changes disrupt photosynthetic tissue continuity.
Start here:
- 1. 1. Keep in stable environment—avoid drafts, heating vents, air conditioning
- 2. 2. Handle carefully when moving—the photosynthetic bark is sensitive to physical damage
