  • Apply Captan, Fruit Tree Spray by Bonide, or organic Copper Soap Fungicide by Natural Guard ferti-lome or Liqui-Cop®. by Monterey to peach and nectarine trees to prevent peach leaf curl before bud swell.
  • Apply Image Herbicide Consumer Concentrate to eliminate Annual Bluegrass (Poa annua), common chickweed, henbit, dollarweed, wild onion and wild garlic.
  • Pre-emerge with Sure Green (Surflan), Hi-Yield Turf & Ornamental Weed and Grass Stopper (a summer annual herbicide), ferti-lome For All Seasons II, orzalyn, or ferti-lome Broadleaf Weed Control with Gallery to turf areas through mid-March to prevent summer weeds such as crabgrass from germinating.
  • Post-emerge to help control those winter weeds. Apply Hi-Yield Kill-Zall as well as ferti-lomeWeed Free Zone on dormant Bermuda when temperatures are above 50 degrees.
  • Plant your container and ball and burlap (B&B) trees.
  • Plant your vegetable garden with potatoes, onion, radishes, broccoli, etc. using and organic product such as our own Redbud Compost to rejuvenate your soil. For clay soils, use gypsum to loosen soil and add calcium to keep down blossom end rot in your tomatoes.
  • At the end of the month, start your garden seeds in a controlled environment to ensure readiness by the first week of April.
  • November through February are the recommended months to apply ferti-lome Tree & Shrub Drench to your young pines for tip borers.
  • When Oklahoma temps are over 40 degrees, apply ferti-lome Dormant Oil Spray to deciduous trees and shrubs to control overwintering insects. NEVER use dormant oil sprays on evergreen trees and shrubs.
  • Soil temperatures determine when weeds emerge in winter and spring.
  • Most weeds germinate after three consecutive days of 50 degrees soil temperature at a depth of 2 inches. You may use the Oklahoma Mesonet site to monitor soil temperature. They also have a free app for Apple and android phones. Better to be sure by applying pre-emerge early rather than too late.
  • For best fertilizer application results, we recommend soil testing.  For quick and easy testing without leaving home, try SoilKit (includes sample bag, pre-paid lab process fee, and return stamped envelope for mailing sample to lab) available at Marcum’s Nursery. Results emailed within 24 – 48 hours with recommendations for soil remediation.
