Groom and Prune Camellias

After flowering is the ideal time to prune camellias. All camellias benefit from tip pruning to keep the plants bushy and full. Thinning overgrown plants encourages them to sprout new growth from the inside of the plant. Rake and clean the soil under the plants when you are finished. Your last step should be to apply a slow-release acid fertilizer.

Deadhead Roses

Remove faded flowers from rose plants to keep them blooming throughout the summer months. After grooming, fertilize with a balanced product to encourage new flowers. Remember, no overhead watering for roses, which encourages fungus disease.

Fertilize Perennials

Apply a granular, slow-release, balanced product around the drip line of perennial plants. Dibble the fertilizer into the soil and then water. Perennials such as salvia, yarrow, astilbes, and daylilies benefit from regular fertilizing.

Treat Garden Hoses Kindly

You garden hose is your garden's best friend in the summer months. Purchase hoses with a lifetime warrantee. If you don't coil the hose after each use, leave it stretched out in a straight line to prevent kinks, the death of hoses. Make sure to reduce the pressure by turning off the water at the hose bib and giving the nozzle a final squirt. Water trapped inside the hose will expand and stretch the inner liner. Store hoses out of the sun to prolong life.

Plant Asters and Goldenrod

Plant asters and goldenrod and other umbrella-shaped flowers to invite predatory insects to your garden. Beneficial insects also thrive in the foliage of dill and fennel. Carnivorous (beneficial) insects devour many types of plant-nibbling insect pests, including aphids.
