Some tips on keeping your garden at its prime for summer are:

-Make sure to keep your eyes out for white flies and aphids.  Spray upper and lower leaves or invest in beneficial insects like ladybugs to keep the aphids and white flys from destroying your plants.  

-prune your roses after the first bloom, either dead heading or cutting them back to get them under control again.  A homemade formula for blackspot on your roses is, 1 TBSP of Baking soda and 1/4 TSP of dishwashing detergent in 1 GAL of water.

- pinch back fall and late summer perennials to keep them at a manageable size and health.  

- prune all of your spring flowering shrubs like Rhododendrons, azaleas and lilacs so they can prepared for next springs blooms.
