  • Vegetables
  • Trees and Shrubs

  • Fruits
    • Continue insect combat and control in the orchard, garden, and landscape. EPP-7306EPP-7313HLA-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
    • Water plants deeply and early in the morning. Most plants need approximately 1 to 2½ 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.” Beneficial Insects 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.
  • Lawn and Turf
    • Brown patch disease of cool-season grasses can be a problem. Lawn Management in OK HLA-6420
    • Meet water requirements of turfgrasses.
    • Fertilization of warm-season grasses can continue if water is present for growth.
    • Vegetative establishment of warm-season grasses should be completed by the end of July to ensure the least risk of winter kill. Establishing a Lawn in Oklahoma, HLA-6419
    • Mowing heights for cool-season turfgrasses should be at 3 inches during hot, dry summer months. Gradually raise mowing height of bermudagrass lawns from 1½ to 2 inches.
    • Sharpen or replace mower blades as needed. Shredded leaf blades are an invitation to disease and allow more stress on the grass.
