But with the scorching heat, it’s crucial to stay on top of garden maintenance and keep your landscape healthy throughout the hottest days of the year.

Planting Strategies for July

While some areas might be too hot to plant anything in July, there are regions in the Northeast, Midwest, and Pacific Northwest that offer a great opportunity to add quick-growing wildflowers and vegetables to extend your gardening season. In the Northeast, you can plant stunning varieties like Alyssum, Red Poppy, Zinnia, and Cosmos that bloom in just a few weeks, creating a magnificent late-season display. These wildflowers not only fill empty spots in your flower beds but also provide nectar for bees, butterflies, and hummingbirds.

For colder regions, July is the perfect time to plant a second round of fast-growing vegetables like beets, radishes, beans, lettuce, carrots, and heat-tolerant greens. These vegetables thrive in cooler temperatures and will prolong your harvest well into the fall.

Maintenance Tips for a Healthy July Garden

Watering in Hot, Dry Regions

July brings some of the hottest and driest days of the year in most regions, making watering a top priority. To keep your plants thriving, it’s best to be proactive and conserve water as much as possible. Remember these watering tips:

  • Give your plants a thorough soaking each time you water, even if it’s only once a week. This ensures their roots receive sufficient hydration.
  • Water your plants in the early morning or evening when the sun is less intense. This prevents rapid evaporation and allows the water to penetrate the soil and reach the roots.
  • Avoid watering the foliage, as it can promote the spread of mildews, rusts, and molds. Consider installing soaker hoses, which deliver water directly to the soil and conserve water, especially in vegetable gardens.
  • Select drought-tolerant varieties like Sedum, Lavender, Echinacea, and Rudbeckia for your landscape. These perennials require less water and thrive in the July heat. Wildflowers are also an excellent low-water solution for sunny spots in your garden.

In regions with high temperatures, extreme moisture, and humidity, keeping your garden healthy can be a challenge. Here are some tips to combat wilting plants, mold, mildew, and fungus:

  1. Prune, thin, and weed regularly to provide adequate air circulation and sunlight, which help plants dry out and stay healthy.
  2. As soon as you spot a diseased plant, immediately trim off the infected area and dispose of it properly.
  3. Water your plants early in the day and at ground level to allow sufficient drying time and prevent mildew.
  4. Opt for tropical bulbs like Canna Lilies, Elephant Ear, Calla Lilies, and Caladium, which thrive in hot and humid weather.
  5. Consider planting varieties that tolerate humidity well, such as Joe Pye Weed, Hibiscus, Swamp Milkweed, Japanese Iris, and Cardinal Flower.
