Mini Gardenias – When to Cut
Q: I have a bank of “mini” gardenias that have made a four-foot high hedge under my front windows. They have bloomed three times so far. When is the best time to cut them back about a foot, top and sides?
A: Because yours bloom so readily I think just about anytime is good although the best time would be after the first bloom in spring. Leaves sprout faster then when temperatures are warm. Right now the gardenia is slowing down its growth and may not make many new leaves if you prune them off now.
