November Lawn Care Guidelines for Oklahoma
- Continue to plant sping flowering bulbs, pansies, kale, and cabbage.
- In the first week, fertilize cool season grasses again.
- Continue mowing cool-season lawns on a regular basis.
- Remove leaves from cool-season grasses or mow with a mulching mower.
- Continue to control broadleaf weeds in well established warm or cool-season lawns with a post-emergent broadleaf weed killer.
- Now is a good time for a soil test to correct nutrient deficiencies before winter.
- Dispose of pine cones of pines infested with Diplodia and Dothistroma. Prune out dead tips.
- Compost annual debris and leaves but do not compost diseased plant parts.
- November 15 to March 15 is the best time to prune most trees and shrubs.
- Prepare the landscape for winter.
- Scale insects can be controlled with dormant oil sprays applied when the temperature is above 40o F in late fall and winter. Do not use “dormant” oils on evergreens.
- Drain gasoline from power equipment or use fuel stabilizer before winter storage. Drain and store water hoses and wrap hydrants. Clean up all tools. Coat metal surfaces with a thin film of oil to prevent rust.
- Remove diseased plant material from the landscape to reduce disease problems next year.
