Fertilizing Your Lawn In Oklahoma

Posted on: February 19th, 2024

Fertilizing your lawn in Oklahoma requires careful consideration of the climate and the specific needs of your grass.

Here are some guidelines on when and how to fertilize your lawn in Oklahoma:

1. Determine the type of grass: Identify the type of grass in your lawn, as different grasses have different fertilization requirements. Common grasses in Oklahoma include Bermuda grass, Zoysia grass, and Tall Fescue. Each grass type has specific preferences for fertilization.
2. Soil testing: Before applying any fertilizer, it is recommended to conduct a soil test. This will help you understand the nutrient levels and pH of your soil, enabling you to choose the appropriate fertilizer and determine the exact amount needed. Contact your local agricultural extension office or a professional lawn care service to assist you with soil testing.
3. Spring fertilization: In Oklahoma, the primary fertilization period for warm-season grasses like Bermuda and Zoysia is during late spring or early summer, around May or June. Apply a slow-release nitrogen fertilizer with a ratio of 3:1:2 or 4:1:2 (nitrogen, phosphorus, and potassium). This will promote healthy growth and green color.
4. Fall fertilization: For cool-season grasses like Tall Fescue, fall is the most critical fertilization period. Apply a slow-release nitrogen fertilizer around September or October, following the recommended application rates based on your soil test results. This fall fertilization helps the grass store nutrients for winter survival and promotes early spring green-up.
5. Proper application: When applying fertilizer, it is essential to follow the manufacturer’s instructions and use the correct equipment. A broadcast spreader is commonly used for even distribution. Calibrate the spreader according to the instructions and walk at a steady pace to ensure uniform coverage. Avoid overlapping or skipping areas to prevent uneven growth.
6. Watering: After fertilizing, water your lawn thoroughly. This helps the fertilizer penetrate the soil and aids in nutrient absorption. Watering also helps reduce the risk of fertilizer burn. Provide around 1 inch of water within 24 hours of application and follow your regular watering schedule afterward.
7. Environmental considerations: Be mindful of environmental concerns when fertilizing your lawn. Avoid fertilizing near water bodies, as excessive nutrients can contribute to water pollution. Sweep any fertilizer that lands on hard surfaces back onto the lawn to prevent runoff. Use phosphorus-free fertilizers unless your soil test indicates a deficiency.
8. Regular maintenance: Fertilization is just one aspect of lawn care. Regular mowing, proper watering, and adequate pest control are also crucial for maintaining a healthy lawn in Oklahoma. Follow a consistent maintenance routine to achieve the best results.

Remember, these guidelines are general recommendations. It is always beneficial to consult a lawn care professional for personalized advice based on your specific lawn conditions and grass type.

Professional weed control companies often provide an integrated approach that combines fertilization and weed control. They understand the relationship between proper fertilization and weed prevention. By hiring these services, you can ensure that both aspects are addressed effectively and in a coordinated manner.
