Q.Gardenia care
I recently received a gorgeous gardenia bush, and the leaves are lush green. There appears to be green buds too. I live in southwestern PA. Having never had a gardenia before, I am anxious to keep it healthy. There were no instructions. Would appreciate any advice you can offer.

Here are some article to help you with the care requirements.
