Q: We enjoy several gardenias in large pots, but they are becoming root bound. Is it advisable to put them in the ground next season?
A: It depends on the variety. Gardenia jasminoides ‘Veitchii’ (florist gardenia) needs indoor protection in most winters. Beside a sunny garage window is a good spot. Florist gardenia placed in living spaces typically suffers leaf scorch due to dry air. On the other hand, varieties such as ‘August Beauty’, ‘Mystery’ and ‘Radicans’ can usually survive fine in a pot kept outdoors. Put them close to a north- or east-facing wall to give protection from wind. These last three also thrive in the landscape. ‘Pinwheel’ and ‘Kleim’s Hardy’ are even more cold-hardy.
