Gardenias, a cure for yellowing leaves
I have done the following first aid on my Gardenia with yellow leaves. I first removed the mulch from around the base of the plant. I than spread 1/2 cups of regular yellow corn meal. I than diluted four table spoons of Liquid Iron and 1/2 cup of Epsom Salt in 2 gals.of water and sprinkled that over the corn meal. I than replaced the mulch. Next I sprayed the top and bottom of the leaves with a solution of three tablespoons of Ultra Fine and one tablespoon of Liquid Iron (Chleated Iron) with one gallon of water.
I finished off the first aid with two cups of fertilizer (Sunniland 8-4-8)placed over the mulch and watered in.
The result is that I have had no more yellow leaves and a whole lot of additional new leave growth. Next will be those wonderful fragrant blooms.
I hope this information will help.
