Do you forget to fertilize your container plants too? We know, it’s actually one of the most common gardening to-do’s that is forgotten. A great recommendation from Horticulture Agent, Dennis Patton, “use a water soluble plant food, following label rates and times. This usually provides a weekly feeding to keep the plants growing.” This is ideal for your container plants, but there is another option for those who are not gung-ho gardeners, but do want to keep your container plants healthy and growing.
Pick up a simple garden fertilizer with a 13-13-13 formula or similar and apply to your plants on a monthly basis. Patton states that for your larger containers (20 to 24 inches in diameter) about 2 tablespoons a month is good. For small containers, you can apply 1 tablespoon or less.
You can get away with using a simple garden fertilizer because your container plants actually need more phosphorus and potassium. Patton also mentions that,” the key is to apply fertilizer regularly, from spring through fall. The last application should be made in early September, to push the annuals right up until frost.”
