The Oklahoma Horticultural Society encourages interest in horticulture in Oklahoma by sharing our knowledge of growing vegetables, fruits, flowers, trees and shrubs. We aquaint ourselves with the best plants and practices for our region by touring inspiring private and public gardens, hosting knowledgeable speakers and welcoming the public to these events.

YOUR INVITED TO JOIN
The Oklahoma Horticultural Society.
The Society was formed in 1970 to further the appreciation of gardening and horticulture throughout Oklahoma. This nonprofit organization recognizes and promotes excellence in gardening and horticulture across Oklahoma and the United States.
The OHS-supported gardening show airs weekly
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.
Oklahoma Gardening monthly tips is produced by the Oklahoma Cooperative Extension Service through the Department of Horticulture and Landscape Architecture and Agricultural Communications Services. Our studio garden is located at The Botanic Garden at Oklahoma State University.
It is a great time to be planning spring and summer gardens.
