Gardenias and Frost
I have 3 bushes, just planted this past spring with a possible frost coming over night. I covered the bushes with plastic bags, but only the top leaves. Will this help and is it ok to leave the trunk uncovered?

First, I would not recommend covering a plant with plastic for frost. Condensation builds up under the plastic and that can harm the plant in the cold. In the future, cover it with a sheet or blanket. The plastic can be placed on top of that.
Other than this, it will help to keep away damage from light frosts to do this.
