Q.Gardenia wilting
Plant was doing well. Replanted it for better drainage. Immediately wilted. Soil is moist. Root measurement and wet soil at top 6, pH 7-8 (I am trying to get 6-7, use acid fertilizer once). There is no new growth. Sun filtered except for 80 min. Some say spray daily, some say don’t. How about filtered water? My friend bought his same time – has new green growth. Replanted using potting soil with a little dirt, as soil WET and Vit B. Leaves aren’t yellow. I have never had success with gardenias. HAMoerke
Your plant is likely stressed from the repotting.
I do recommend using only sterile good quality potting soil for your plant.
Using soil from the garden causes to much compaction and the roots will not be able to breath.
This certainly can add to the wilting issue.
Keep in mind that your plant is likely getting ready for winter, so the growth will be slowing down.
Do not over fertilize or try to fertilize it into health.
As the humidity drops as we enter fall, misting the plant can certainly help.
