I have gardenias iin the ground . If we have a mild winter, we get blooms. But I'm keeping eight gardenias iin the greenhouse ovet the winter so we will have blooms on them regardless of the winter. When I bring them out, I dig them in about halfway down the pot so the wind doesn't blow them over. They ate easier to water if they aren't sidewasys! So today I brought them out and dug five of them in. Some already have buds.
