MAINTENANCE GUIDELINES

MARCH GUIDELINES

•       Apply ferti-lome Fire Blight Spray to help control and prevent blight on crabapple, pears and fruit bearing trees when they begin to bloom.  This is the only opportunity to apply this prevention.

•       Apply 3-4” of Marcum’s Gold Diamond Cedar to control weeds in beds.

•       Plant your container and Ball & Burlap (B & B) trees.

•       Plant onions, potatoes and cool season vegetables after night time temps stay above 30 degrees.

•       Get garden and flower beds ready to plant by tilling Red Bud Compost into soil.

•       Pre-emerge with ferti-lome For All Seasons II,  Hi-Yield Turf & Ornamental Weed and Grass Stopper (a summer annual herbicide) or Sandbur and Crabgrass Preventer to turf areas through mid-March to prevent summer weeds such as crabgrass from germinating.

•       Soil Temperature, Winter and Spring Weeds:

      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 Mesonet web site for Oklahoma to monitor soil temperature (mesonat.org). They also have a free app for Apple and android phones.  Better to be sure by applying pre-emergent early rather than too late.

•       The month of March marks the first of four applications to fertilize your cool-season lawns (Fescue and Rye Grass) with Marcum’s Slow Release Fertilizer 18-6-12 or Milorganite. Additional months for application include: May, October and November.

•       Apply ferti-lome Weed Free Zone, a post-emergent broadleaf herbicide, to cool and warm season lawns to control broadleaf weeds.

•       In mid-March seed cool-season turf grass or when daytime temps are between 55 and 70degrees. This time can be different each year.

•       Mow cool-season grasses at 1½ to 3¾ inches high.

•       Apply Wilt Stop to protect your small plants when temps are below 50 degrees to add to your plant’s ability to better tolerate the cold.

•       High Yield Dormant (Oil) Spray may still be applied to all deciduous shrubs and trees while they are dormant to control mites, galls and over wintering aphids, etc.

•       Prune roses just before growth starts and use ferti-lome Rose and Flower Food with Systemic Insecticide as the foliage appears.  Use very six weeks for best flowers and insect control.

•       In late March, detach warm season lawns (Bermuda and Zoysia).
