August Gardening Tips

August gardening tips in Northeast Florida come after the passing of summer vacations with children back to school, the arrival of afternoon thundershowers, and sweltering afternoon heat.

August soil and air temperatures make it prime time for tree planting. Vitex trees, powder puff trees, Lil’Gem magnolias, crape myrtles, cassia, and bottlebrush are a few of the varieties available here at Earth Works.

Manager Matt talks in this video about a wide variety of trees available to buy and what to expect from each and their care needs.

Stake plants that need additional support for average growth and protection against bad weather. A few that come to mind include vegetables, roses, hibiscus, newly planted palms, and citrus trees.

Continue blowing and raking unwanted leaf litter off the lawn and out of the flower beds. Refresh pine straw used as mulch that, as it breaks down, adds much-needed organic matter to your soil required for healthy soil microbial action.

Deadheading flowers preserve plant energy for new growth and blooms. Otherwise, pruning in August should be based on the 4 “Ds,” which is to prune dead, dying, diseased, or damaged branches at this time. Prune Spring blooming plants soon after they bloom. Wait until winter to prune your summer bloomers.

Fill in patches of empty spots in your flower beds with new plantings or temporarily with other potted plants. Don’t stress the transition between your Spring and Fall flower beds at their prime. Enjoy the view. Consider our monthly container gardening recipes to spur your ideas on what to grow and display now and in the coming seasons.

Closely monitor your plant’s watering needs specific to their growing conditions and requirements in-ground, new plantings, transplants, potted container plants, and indoor plants. If your lawn and garden irrigation timer run on manual settings adjust where appropriate as the days are shorter, and precipitation and temperatures vary dramatically daily. Be wary of fungal diseases from overwatering or watering at the wrong time.

In August, all the major lawn pest threats can be at the peak of their lifecycle in our lawns. These pests include chinch bugs, mole crickets, and sod-webworms. Garden pests during August include Thrips & fungus are typically a higher threat for roses than many plants risk from mealybugs, spider mites, and scale. Sooty mold covering leaf surfaces naturally grows on the honeydew secretions of sucking insects. Regularly have a person-to-plant meeting with each plant, observing its condition to stay ahead of threats to their health. Our garden center managers can make a solid recommendation for specific pest needs with your pest & plan picture brought to us at the garden center.

If you haven’t planted seeds by early August, you can purchase seedlings of your favorite herbs and veggies at our garden center. In August, gardeners sow carrots, beans, beets, carrots, kale, lettuce, and spinach. We have weekly shipments of select herbs and veggies including heirlooms in season.

“Fertilization” is a complicated topic often oversimplified. In comparison, some houseplants may get weekly balanced feedings while the turf stays lacking in nitrogen fertilization due to some county fertilization blackout periods through August and September to protect lakes, rivers, and the ocean as wildlife habitats from algae blooms. Palms, typically deficient in iron, manganese, magnesium, and sulfur, can be supplemented with Palm Nutritional by Southern Ag. Azaleas and camellias can use a boost in August. Heavy feeders like birds of paradise would appreciate periodic composted cow manure dosing too. The water lilies benefit from Aquabloom Aquatic Plant Fertilizer that’s slow release and doesn’t harm other aquatic life. In the following video Jason Duffney discusses water lily transplanting and care.

Gardening is a labor of love that gives back what you put into it. August gardening tips wrap with a reminder to stop and smell the roses. Enjoy the fruits of your labor.
