After years of working in the industry and building nurseries around Oklahoma’s inclement climate, we suggest the following maintenance guidelines.

  • Get ready for mums, pansies, and kale fall plantings.
  • Plant your container and evergreen trees.
  • Select your deciduous B & B (Ball and Burlap) trees for fall/winter planting.
  • Last nitrogen fertilizer application of the year on warm-season grasses should be applied no later than September 15.
  • Apply ferti-lome F-STOP for brown patch disease for fescue grass.
  • Apply Hi-Yield Grub Free Zone II to keep mole crickets and white grubs away all season long.
  • Pre-emerge using Orzalyn (Surflan), ferti-lome For All Seasons II Lawn Food Plus Crabgrass and Weed Preventer containing prodiamine (Barricade) or Hi-Yield Turf and Ornamental Weed & Grass Stopper to keep annual Blue grass from emerging plus other winter weeds. Apply by the second week of September. NOTE: Do NOT treat areas that will be seeded in the fall for fescue lawns.
  • Seed bluegrass, fescue, or ryegrass as needed in shady areas in late-September through mid-October.
  • See Marcum’s watering guidelines for plants, trees, and shrubs.
  • Spring bulbs (tulips, daffadils, hyacinth, etc.) arrive in mid-September.
