1. Apply weed and feed fertilizer to control broadleaf weeds and clover. Apply in the morning on wet grass so that particles cling to weed foliage. Plan your application for when dry weather is forecast for at least 48 hours.
2. Remember to raise mowing height to 3 inches to conserve water during the hot months of July and August. Lawns will need a high nitrogen feeding during this time.
3. Apply a weekly fertilizer to give vegetable plants a healthy start and keep them producing all summer long.
4. Start seeds for fall vegetable crops.
5. Stake tomato plants and remove suckers to ensure maximum production.
6. Replant heat-tolerant lettuce varieties for summer salads.
7. Feed roses with rose food and systemic insect control.
8. Deadhead annual and perennial flowers to encourage repeat bloom. Discard spent flowers to avoid spreading disease.
9. If transplanting spring-flowering bulbs, such as daffodils, tulips, and minor bulbs, lift and separate at this time. Apply a fungicide treatment; store in a cool, well-ventilated space; and allow bulbs to rest until fall before replanting.
10. Apply a layer of mulch to beds to control weeds and conserve moisture.
11. Give plants a weekly feeding of liquid fertilizer to keep them performing all summer long.
12. Fertilize flowering trees and shrubs such as rhododendrons, azaleas, and other broadleaf evergreens after blooming. This is also the best time to prune, before next year's buds have set.
13. Continue to plant out container-grown trees, shrubs, perennials and annuals.
14. In colder regions early June is the time to plant out cannas, gladiolus and dahlias.
15. Over-plant with annuals to cover late-summer bare spots.
16. Now is the time to plant out fall crops such as brussels sprouts and cabbages.
17. Sow warm-weather vegetables and herbs such as parsley, coriander and basil.
18. Time to tidy up the dogwoods and crabapples. Prune out diseased wood and water sprouts.
19. Followup on your rose feeding schedule. They should be fed monthly through the summer.
20. Take precautions to water spring-planted trees and shrubs. When rain is in short supply, water deeply weekly.
21. June is a great time to visit arboretums, garden centers and garden tours to get inspiration and ideas for plant selection and garden design.
22. Water the lawn as need to provide at least an inch and a half of water per week. Use a rain gauge to best estimate the amount of time needed for sprinkler applications.
23. Make it a weekly practice to get out in the garden and weed. They're easier to pull when young and chemical control will not be necessary later.
24. Towards the end of June you will want to thin out the cool-season vegetables such as spinach, carrots, radishes and cool-season peas. Remove lettuce as the heads bolt during warm weather.
25. Place netting over ripening berries to protect from birds and deer.
26. Keep vegetables and berry bushes well watered.
27. Get creative. There is no reason why roses cannot be added to perennial borders and vice versa.
28. You can attract colorful songbirds throughout the summer by continuing your bird feeding schedule. Supplement with fresh fruit. Remove suet cakes as they turn rancid quickly during warm weather.
29. Plan on planting out several perennial plants designed to attract butterflies.
30. Add the element of fragrance to your home landscape through select roses, perennials and shrubs.
