Garden Tips of July

David Hillock

Vegetable Garden

  • Make fall vegetable garden plantings in late July. Fact Sheet HLA-6009 gives planting recommendations.

Lawn

  • Brown patch disease of cool-season grasses can be a problem. (HLA-6420)
  • Meet water requirements of turfgrasses. (HLA-6420)
  • Fertilization of warm-season grasses can continue if water is present for growth. (HLA-6420)
  • Vegetative establishment of warm-season grasses should be completed by the end of July to ensure the least risk of winter kill. (HLA-6419)
  • Mowing heights for cool-season turf grasses should be at 3” during hot, dry summer months. Gradually raise mowing height of bermudagrass lawns from 1 ½ to 2”.
  • Sharpen or replace mower blades as needed. Shredded leaf blades are an invitation to disease and allow more stress on the grass.

Tree and Shrub

  • Control bermudagrass around trees and shrubs with products containing sethoxydim, fusilade, or glyphosate herbicides. Follow directions closely to avoid harming desirable plants.

Fruits

  • Continue insect combat and control in the orchard, garden, and landscape. (EPP-7306, EPP-7313, EPP-7319)
  • Check pesticide labels for “stop” spraying recommendations prior to harvest.
  • Harvest fruit from the orchard early in the morning and refrigerate as soon as possible.

Flowers

  • Divide and replant crowded Hybrid iris (Bearded Iris) after flowering until August.

General Landscape

  • Water plants deeply and early in the morning. Most plants need approximately 1 to 2 ½ inches of water per week.
  • Providing birdbaths, shelter and food will help turn your landscape into a backyard wildlife habitat.
  • Insect identification is important so you don’t get rid of the “Good Guys.” (EPP-7307)
  • The hotter and drier it gets, the larger the spider mite populations!
  • Expect some leaf fall, a normal reaction to drought. Water young plantings well.
