Things to Do This Month
|
Ornamental Annuals and Perennials
- Continue to treat roses and susceptible tall garden phlox with fungicide every two weeks to control foliar diseases. Don’t spray when temperatures exceed 80 degrees F.
- Make final pinch of mums before July 15th.
- Divide bearded iris this month.
- Deadhead perennials after flowering for a neat appearance, and deadhead annuals that require it for continued bloom.
- Water container gardens daily as required, and fertilize weekly with water soluble plant food.

Trees and Shrubs
- Keep watering newly planted trees and shrubs as needed.
- To propagate spring flowering shrubs, take semi-hardwood cuttings now.
- Spray hollies for leaf-miner control.
- Watch for spider mite damage on susceptible plants. Look for speckled, yellowing foliage, and in severe infestations, silky webbing.
Fruits and Vegetables
- Mulch tomatoes and peppers and water when soil begins to dry to prevent blossom-end rot.
- Set out transplants of cool-season crops such as broccoli, cabbage and cauliflower.
- Sow seeds of carrots, collards, kale, radishes and turnips.
- Spray second treatment for peach tree borers.
Miscellaneous
- Shop the garden centers for midsummer bargains. Think tropicals and water garden plants! No matter how cheap, avoid damaged, diseased or stressed plants. Perennials, trees and shrubs also can be planted now or healed in temporarily for fall planting. Be sure to monitor and water as needed.
