MAINTENANCE GUIDELINES

JUNE GUIDELINES

  • Plant your container Ball & Burlap (B & B) trees.
  • Remove all dead branches on established trees.
  • Remain alert for insect damage and add spider mites to the list. Foliage may become pale and speckled; juniper foliage turns a pale yellowish color. Shake a branch over white paper and watch for tiny specks that crawl.
  • Look carefully for bagworms. These are tiny brown bags barely visible to the eye. If found, easier to treat at earlier stages rather than later. Apply Hi-Yield Malathion, Natural Guard by ferti-lome Spinosad
  • Pine needle disease treatments are needed again in mid-June. Apply Copper Fungicide.
  • Cultivate and mulch using Gold Diamond Cedar Mulch. This reduces  evaporative water loss from the soil surface,  growth of weeds and prevents soil compaction.
  • Fertilize warm season grasses with Marcum’s Nursery’s exclusive fertilizers made for Oklahoma: Kelly Ray’s  (46-0-0), Big Mont’s Nitro Green (31-0-0), BR’s Lawn Tonic (28-6-12) or The Marcum’s Original Slow Release (18-6-12). 
  • By mid-May, “Dollar Spot” disease may be visible on lawns. Apply ferti-lome Liquid Systemic Fungicide or ferti-lome F-Stop. Be sure to fertilize prior to applying a fungicide.
  • Seed warm-season grasses (Bermuda and Zoysia) in mid-May through the end of June to reduce winter kill losses..
  • Meet water requirements of turf.
  • Post-emergent control of crabgrass and summer annual grasses is best performed on young plants using ferti-lome Weed Out with Q. This product kills crabgrass, dandelion, clover, plus 200 other listed weeds.
  • Apply Image Nutsedge Killer, Image All-In-One Lawn Weed Killer or Monterey Nutgrass Killer II Selective Herbicide to eliminate yellow and purple nutsedge.
  • See Marcum’s Watering Guidelines for new and established trees.
  • For preventative white grub treatments, apply Hi-Yield Grub Free Zone III in late June to mid-July.
