Gardenia bush turning yellow
I'll bet this is a common concern but unable to find solution. Five gardenia bushes were planted this time last year. One has always been poor and has not grown much. Now almost all the leaves are yellow. What is the best treatment to invigorate this plant. It receives sun most of the day and we keep it watered. I get totally confused about what is best fertilizer to use on gardenias. What ever you suggest I'll do for sure. I live in Central Mississippi.
