Can You Convert a Gardenia Bonsai to a Regular Pot?

True bonsai gardenias are trained for years to stay miniaturized in shallow trays. Moving to a slightly deeper planter is possible but risky—shock is likely unless you have bonsai repotting experience. A much larger pot will cause root rot.

Better Option

Set up a watering reminder or give the plant to someone who can maintain its demanding schedule. Gardenias need constant moisture, cool temps, and high humidity to bloom.
