Q.Coffee Grounds For Potted Gardenia?
I have a potted Gardenia out on my patio. it only gets AM sun. Is it alright to add coffee grounds to soil? I use Mir-Acid every two weeks. It looks great with new growth. I live in Arizona and so far the intense heat has not bothered. We’re in the hundreds. Will it survive this heat all Summer or should I bring it in the house?

On the coffee, if they are used grounds, they will not acidify the soil, but can help improve drainage. Your plant will let you know if the heat is too much. Keep it watered and fertilized. These articles should help:
