What can I do for my yellowing Gardenia?
I have a 4ft gardenia in a 3 gallon pot. I've had it for about six months and recently its started getting a few yellowing leaves on the lower branches. I gave it a tablespoon of epson salt 8 days ago and two tablespoons of all purpose fertilizer(16-16-16) 5 days ago but the yellowing has continued. I water it when the soil feels dry, which works out to be every day or two. Is it dropping unnecessary leaves or is this a problem and what can I do?
