We will be planting some frost proof Crown Jewel Gardenias and are wondering what is the best soil to add. Also, what is the best way to care for frost proof gardenias during very c old weather. Thank you.

While these plants are technically able to survive in our area, some reports suggest that they might not thrive and will definitely need some protection in our difficult winters. That would include placing it in a somewhat protected place, perhaps in a nook or against an eastern-facing brick wall. You may also want to build a wire cylinder around it and stuff it with dry leaves or wrap it with burlap.
As far as planting, these plants enjoy an acidic soil, so mix in some peat moss, or compost and fertilize with Hollytone.
