Whenever your summer blooms faded and have bloomed away, make sure to deadhead the plants. This implies grabbing the flower heads off. This will promote new plants to grow next year, and it will also strengthen the place. Considering that the flower heads have seeds, you can even save the flower heads which you have squeezed off for planting at another time.
A great way to keep bugs and insects at bay in your backyard is to spray your flowers with a dish soap and water mixture. A mixture of one half teaspoon dish detergent and one-quart water may kill-off those pesky parasites.
