Frequently Asked Questions

Why is my Begonia Rex dropping leaves after I brought it home?

Rex begonias are sensitive to changes in light, humidity, and temperature. Some leaf drop after a move or repotting is normal transplant stress — keep conditions stable and it should recover within a few weeks.

Can I propagate Begonia Rex from a single leaf?

Yes — Rex begonias are well known for leaf-cutting propagation. Lay a leaf flat on moist soil with the veins nicked, or cut it into wedges, and new plantlets will sprout from the veins.
