Trees

• Prune spring flowering shrubs- After they are done blooming, approximately early June
• Keep trees & shrubs well watered throughout the summer, with approximately 1 inch of water per week. Apply water in one application so that is soaks in deeply and moistens the top 18-24 inches of the soil.

Lawn Care

• Apply 2nd application of pre-emergence to lawn for crabgrass control, July 1-July 7
• Apply grub control- using Merit or GrubX, apply from May through June, but before July 1st
• Sharpen your lawn mower blade monthly
• Lawns maintained at the correct height are less likely to have disease and weed infestation. Kentucky bluegrass and tall fescue should be mowed at two or three inches in height. Mow frequently, removing no more than one third of the blade at each cutting.

Vegetable Garden

• Turn compost pile
• Cabbage loopers and imported cabbage worms are green worms. They leave large holes in the leaves of plants in the cabbage family. For control, caterpillars can be picked off by hand or sprayed with Bt (Bacillus thuringiensis), a natural, non-toxic preparation available by various trade names.
• Newly transplanted vegetable plants should be protected from cutworms with collars. Cut strips of cardboard two inches wide by eight inches long, staple them into circles and place them around the plants. Press the collar about one inch into the soil. These collars will fence out the cutworms and protect the stems of the vegetable plants.
• Stay out of the garden when the vegetable plant leaves are wet. Walking through a wet garden spreads disease from one plant to another.
• Four or five layers of newspaper will serve as an effective mulch in the garden. Cover it with grass clippings or straw to prevent it from blowing away.

Ornamentals

• Watering roses with soaker hoses or drip irrigation will reduce the spread of black spot disease.
• Deadhead annuals as their flowers start to fade. This will encourage continued blooming throughout the summer. Many perennials also respond well to deadheading.
• Grass clippings can be used as a mulch in flower beds and vegetable gardens if allowed to dry well before use. Never use clippings from a lawn that has been treated with a herbicide.

Garden Planning

• Make notes of plants that are not doing well throughout the growing season and plan to relocate them in fall to a better site in the garden.
