October Lawn Care Guidelines for Oklahoma
- Plant spring flowering bulbs now in well-drained soils with good sunlight. Planting depth is two times bulb diameter.
- Plant pansies, kale, and cabbage.
- Dig and store tender bulbs and tubers in a cool dry place.
- Container-grown shade trees and pines are most successfully planted in the fall. Broadleaf evergreens or bare-root plants are best planted in the spring.
- In mid-month, fertilize cool season lawns.
- Seeding of cool-season grasses for perennial lawns can continue through mid-October.
- Over-seeding of warm-season lawns with cool-season grasses for winter should be performed late this month. Warm-season lawns are healthiest if winter over-seeding is not performed!
- Continue mowing cool-season lawns on a regular basis, even if warm-season grasses have quit growing.
- Remove leaves from cool-season grasses or mow with mulching mower.
- October is an excellent time to control broadleaf weeds in well established warm or cool-season lawns with a postemergent broadleaf weed killer. Donít apply to seedling fescue.
- Mow and edge neatly before killing frost. Clean up marginal water garden plants after first frost kills the tops.
- Place a net over the water garden to prevent leaves from falling in the water.
- Remove diseased plant material from the landscape to reduce disease problems next year.
