If you want to maximize the flower show, you should fertilize shrubs after they finish flowering. Pruning should be completed before July in order to give plants enough time to bloom. Fertilize your plants with a balanced fertilizer every two to three weeks, depending on the type of plant you’re growing.
You can also add a small amount of compost to the soil to help promote healthy root growth. If you don’t have access to a compost pile, you can use a soil amendment such as peat moss or composted cow manure. Mix the mixture into the potting mix and allow it to sit for a few days before adding to your soil mix.
