Repotting a Flowering Begonia: Proceed with Caution

Minimize Root Disturbance

If the pot is truly too small (roots filling every gap), you can repot now:

1. Gently remove root ball intact—do not tease or break roots.
2. Move to a pot ≤4 inches wider in diameter.
3. Mix 2 parts soil : 1 part perlite for drainage.
4. Water in, keep in same light.

Better: Wait

Flowering plants need to be potbound to bloom. Disturbing roots often aborts flowers. Water daily if needed to keep moist in current pot.

Early growing season helps recovery, but risk remains.
