By mid-summer, many summer annuals have already produced plenty of flowers, and some may be starting to set seed. Once this happens, plants shift their energy toward maturing seeds instead of producing more blooms. You can encourage fresh flowers by “deadheading,” or removing the faded blossoms. Snip off the spent blooms, give the plant a boost with a liquid fertilizer following the label instructions, and keep it well-watered. This helps redirect energy back into growth and flowering instead of seed production. 

Marigolds, zinnias, cosmos, verbena, geraniums and petunias all respond well to deadheading. That said, many modern hybrids of petunias, zinnias, and verbena are bred to keep blooming steadily without it. If your plant is vigorous, green and producing new flowers, you can skip the step. 

Container plants often get overgrown or tired-looking by mid-summer. A good trim can spark fresh growth, but sometimes the best option is to replace them entirely. Swapping in new plants can instantly brighten an entryway or patio and give your outdoor spaces a refreshed look. 

Regular watering is essential during the hottest months. Annual flowers and vegetable gardens often need water every few days. Deep watering every other day is better than a light sprinkle daily, as it encourages roots to grow deeper. If a good summer rain soaks the soil, you can safely skip your next watering. 

If plants lose their rich green color or their growth slows, they may need feeding. Applying a liquid fertilizer as directed on the label can bring noticeable results in just a few days. For best results, water the soil first — feeding dry plants will have little effect. 

Trees and shrubs usually require less attention in summer. Established woody plants are fairly drought-tolerant and can often go a week to 10 days without rain. If summer storms damage limbs, prune them back at any time. You can also remove spent flowers from shrubs now but save major pruning for late winter or early spring.
