June Gardening Calendar

Vegetables

• Weeks 1-2: As soon as cucumber and squash vines start to ‘run,’ begin spray treatments to control cucumber beetles and squash vine borers.
• Weeks 1-2: Repeat plantings of corn and beans to extend the harvest season.
• Weeks 2-4: Set out transplants of Brussels sprouts started last month. These will mature for a fall harvest.
• Weeks 2-4: To minimize diseases, water with overhead irrigation early enough in the day to allow the foliage to dry before nightfall.
• Weeks 2-4: Soaker hoses and drip irrigation systems make the most efficient use of water during dry times.
• Weeks 2-3: Start seedlings of broccoli, cabbage and cauliflower. These will provide transplants for the fall garden.

Fruits

• Week 1: Enjoy the strawberry harvest
• Week 1: Thinning overloaded fruit trees will result in larger and healthier fruits at harvest time. Thinned fruits should be a hands-width apart.
• Weeks 2-3: Begin control for apple maggot flies. Red painted balls that have been coated with tanglefoot may be hung in apple trees to trap egg-laying females.

Lawns

• Mow bluegrass at 2 to 3.5 inch height. Turfgrasses growing in shaded conditions should be mowed at the higher recommendations.
• Gradually increase the mowing height of zoysia lawns throughout the summer. By September, the mowing height should be 2 to 2.5 inches.
• Mow lawns frequently enough to remove no more than one-third the total height per mowing. There is no need to remove clippings unless excessive.

Ornamentals

• Week 1: Deadhead bulbs and spring flowering perennials as blossoms fade.
• Weeks 2-4: Plant tropical water lilies when water temperatures rise above 70 degrees.
• Weeks 2-4: When night temperatures stay above 50 degrees, bring houseplants outdoors for the summer.
