- Fertilize warm season grasses using one of Marcum Nursery’s exclusive fertilizers made in Oklahoma: Kelly Ray’s Fast Growing Fertilizer 46-0-0, BR’s Lawn Tonic 28-6-12, Original Slow Release Fertilizer 18-6-12 or Big Mont’s Nitro Green 31-0-0.
- Mowing heights for cool-season grasses should be 3″ during hot, dry summer months. Gradually raise the mower height of bermuda grass lawns from 1 and 1\2 to 2 inches.
- Treat “Dollar Spot” disease on lawns with ferti-lome Liquid Systemic Fungicide or ferti-lome F-Stop. Be sure to fertilize prior to applying a fungicide.
- Meet water requirements of turf.
- The hotter and dryer it gets, the larger the spider mite populations become. Spray plant foliage with Hi-Yield 55% Malathion, Natural Guard by ferti-lome Insecticidal Soap Concentrate or Natural Guard by ferti-lome Spinosad.
- Look carefully for bagworms. These are tiny brown bags barely visible to the eye. If found, easier to treat at now than later. Apply Hi-Yield 55% Malathion, Natural Guard by ferti-lome Spinosad, or Natural Guard by ferti-lome Caterpillar Spray with BT.
- For preventative white grub treatments, apply Hi-Yield Grub Free Zone II in late June to mid-July.
- Expect some leaf fall, a normal reaction to drought.
- Revitalize your trees and shrubs with ferti-lome’s Fish Emulsion.
- Don’t forget to mulch! Marcum’s has many choices of premium mulches to choose from.
- See Marcum’s Watering Guidelines for planting trees and shrubs.
