Garden Tip for April
- Most bedding plants, summer flowering bulbs and annual flowers seeds can be planted after danger of frost. This happens around mid-April in most of Oklahoma.
- Let spring flowering bulb foliage remain as long as possible before removing it.
- Wait a little longer for temperatures to warm up before planting cucurbit crops and okra.
- Plant vegetable crops in successive planting to ensure steady supply of produce rather than harvesting all at once.
- Hummingbirds arrive in early April. Get your bird feeders ready by using one part sugar and four parts water. Do not use red coloring.
Lawn and Turf Tips
- Warm season grass lawns can be established beginning late April from sprigs, plugs or sod.
- Fertilizer programs can begin for warm-season grasses in April.
- Mowing of warm season lawns can begin now. Cutting height for bermuda and zoysia should be mowed at one to one and a half inches high and buffalo grass at one and half and three inches high.
Trees and Shrubs
- Don’t spray insecticides during fruit tree bloom or pollinations may be affected. Disease sprays can continue according to schedule and label directions.
- Continue spray schedules for disease prone fruit and pine trees.
- Proper watering of newly planted trees and shrubs often means the difference between success and replacement.
- Fire blight bacterial disease can be controlled at this time. Plant disease resistant varieties to avoid disease.
- Remove any winter damaged branches or plants that have not begun to grow. Prune spring flowering plants as soon as they are finished blooming.
