You may also have ants harvesting sugars and bringing more in so tackle those too. A syrup madeup of 1 cup sugar 1/2 cup hot water 1 tablespoon borax 1 tablespoon boracic acid which is boiled for 2 -3 minutes and cooled. Just dob it around where you see ant trails they will soon disappear. Also look at whether your soil is alkaline. Gardenias are like camellias and azaleas where they like acid soils. If you are near the beach suburbs replace it with something else you'll have no hope. |
