Please tell me how to get rid of grub worms from my flower pots .There is a lot of rainfall here in the hills. Some plants have black spots on the leaves eg impatiens and fuschia.
My potted plants are heavily affected by white mealybug and there are huge ant colonies inside the soil of the pots. They ate up at least 15 healthy marigold plants. Will the same solution help? Please reply! Don't want to use chemical..
