June landscaping may include visit to plant clinic

NORTHWEST FLORIDA—June brings hotter temperatures, humidity, and possible thunderstorms. In addition, school is out, and many people go on vacation. This leaves less time for landscape and garden tasks. But there are things to do in the June landscape and garden here in the Northwest Florida area.

In today’s article, I’ll share some ideas from the UF/IFAS Extension North Florida Gardening Calendar for the month of June and invite you to attend our June plant clinic.

Annuals that can take full sun during hot summer months include celosia, portulaca, vinca, and some coleus. See Annuals.

Add bright color to the landscape with perennials. See Perennial Landscape Plants.

Summer’s warm, rainy weather is the perfect time to plant palms. Make sure not to cover the trunk with soil. And choose cold-hardy palm species for North Florida. See Palms.

Plant heat-loving herbs, including basil, Mexican tarragon and rosemary. Pinch back regularly to prevent flowering and enhance branching. See Herbs.

Plant okra, southern pea, and sweet potato. See Vegetable Gardening in Florida.

If rainfall has been lacking, watch for drought stress and water as needed. See Landscape Irrigation.

Prune lightly during the warmer months to encourage more branching and blooming. Azaleas can still be pruned in June without removing next spring’s flower buds. See Pruning Landscape Trees and Shrubs.

Yellow and brown patches in St. Augustinegrass can be caused by chinch bugs, disease, or lack of water. Take time to determine the cause so your remedy is effective. Rejuvenate areas where grass does not grow well by replacing it with a more adapted turf or groundcover, such as mondograss, perennial peanut, or Asiatic Jasmine.

You could also use mulch instead of lawn grass on slopes or underneath large trees. Choose wisely. See Garden Pest Insects and The Florida-Friendly Landscaping™ Guide to Plant Selection & Landscape Design.

The June plant clinic will be held on Friday, June 21, from 9 a.m. to 12 p.m. at the temporary UF/IFAS Extension Annex, located in the back of the Okaloosa Technical College Campus at 1976 Lewis Turner Boulevard in Fort Walton Beach.

If you have a plant problem you’d like diagnosed, bring a sample of the weed, plant, insect, etc., to the clinic. The sample should be fresh and represent what is seen in the landscape. This may include a plant stem with several leaves, a 4-inch square of grass with roots attached, etc.

You also may bring a sample of soil for pH testing.
