- Why are there yellowing leaves on gardenia plant?
Gardenias are notorious for getting yellow leaves and it can happen for many reasons. Yellow leaves normally signal that the plant is under some type of stress. In order to remedy the problem, you must first try to pinpoint the issue. Anything from poor drainage, root problems, high pH levels, or not enough nutrients can all lead to leaf yellowing in gardenia plants. Start by checking the plant?s soil. If it?s too wet, this could signal an issue with drainage or even overwatering. Testing the soil is another good idea to see what, if any, nutrients are missing or if the soil pH is too high. I would also check the plant for pests. A number of insects attack these plants, which can cause yellowing.
