How to Manage Gardenia Winter Cold DamageUh-oh. Does your outdoor gardenia have brittle branches and brown leaves following a bout of freezing temperatures?
If you’re left wondering whether the ornamental shrub, Gardenia jasminoides, could come back from that damage, my answer is a definite, “Maybe.”

So, it’s not a given that a gardenia will succumb to the cold.

Will it survive? This depends on whether the plant was healthy ahead of the freeze and how much damage it incurred. Keep reading for tips on assessing the
