Lawn Care Guide: Optimal Aeration Timing for Cool and Warm Season Grasses in Oklahoma

Best Time to Aerate Cool and Warm Season Grasses in Oklahoma

Maintaining a beautiful lawn is crucial for property owners, whether it’s for aesthetic or functional purposes. Aeration is a vital lawn care practice that creates small holes in the soil to promote the growth of healthy grass roots. In Oklahoma, the best time to aerate varies depending on the type of grass. This article will guide you on the optimal time to aerate cool and warm season grasses in Oklahoma for improved lawn health.

Best time to aerate cool season grasses in Oklahoma:


Cool season grasses such as tall fescue, Kentucky bluegrass, and perennial ryegrass are prevalent in Oklahoma. They grow actively in the fall and spring, while their growth rate slows in the summer months. Aeration should take place during the fall, between late August and early November. Aerating during this period enables the grass to recover and develop deeper roots before the winter season sets in. Avoid aerating during summer months as it can cause grass stress and potential damage.


Best time to aerate warm season grasses in Oklahoma:

Oklahoma has several types of warm season grasses, including Bermuda grass, Zoysia grass, and buffalo grass. These grasses grow vigorously in the hot summer months and become dormant in winter. Late spring or early summer, between late May and early July, is the best time to aerate warm season grasses. Aerating during this period enables the grass to recover and develop deeper roots before the hot and dry summer months set in. Avoid aerating during the fall and winter as the cooler temperatures can cause grass stress and damage.


Lawn aeration is crucial for maintaining a healthy lawn, but the timing of the aeration process is essential for optimal results. In Oklahoma, the timing varies based on the type of grass you have. For cool season grasses, aerate in the fall, while warm season grasses should be aerated in late spring or early summer.

The Ultimate Guide to Weed Control and Fertilization for a Lush Lawn

Welcome to TurfWorks, your go-to resource for everything lawn care-related. In this post, we’ll provide you with the ultimate guide to weed control and fertilization for a lush lawn.

Achieving a healthy and green lawn takes effort and know-how. Two critical factors for a thriving lawn are weed control and fertilization. We’ll provide you with some tips and tricks to help you achieve the lawn of your dreams.

Weed Control

Weeds can be a nuisance to any lawn. They compete with grass for resources such as water, nutrients, and sunlight. Here are some weed control tips that can help you achieve a weed-free lawn:

  1. Proper mowing: Mowing your lawn to the right height is crucial for weed control. Mowing too short can stress the grass and create bare spots, which can make it easier for weeds to take root.
  2. Aeration: Aerating your lawn can help improve the health of your grass and reduce the likelihood of weeds taking root. By aerating, you allow water, nutrients, and air to penetrate the soil more easily, promoting stronger roots and better overall health.
  3. Post-emergent herbicides: Post-emergent herbicides can be applied directly to weeds that have already emerged. These herbicides work by killing the weed and leaving the grass unharmed.


Fertilizing your lawn provides it with the nutrients it needs to grow strong and healthy. Here are some fertilization tips that can help you achieve a lush, green lawn:

  1. Soil testing: Before applying fertilizer, test your soil to determine its nutrient content. This will help you choose the right type and amount of fertilizer for your lawn.
  2. Organic fertilizer in late summer: Late summer is an excellent time to apply organic fertilizers. These fertilizers release nutrients slowly over time, providing a steady supply of nutrients to your lawn. Organic fertilizers also improve soil health and promote microbial activity, making them an excellent choice for long-term lawn care.
  3. Timing is key: Applying fertilizer at the right time is crucial for optimal absorption by the grass. Apply fertilizer during the growing season and avoid fertilizing during drought or extreme heat.
  4. Watering: After applying fertilizer, be sure to water your lawn to help the nutrients penetrate the soil and reach the grass roots.

Weed control and fertilization are essential elements for achieving a lush, green lawn. By following these tips and tricks, you can help ensure that your lawn stays healthy, strong, and beautiful year-round. Remember to always read and follow the instructions on any products you use and to be mindful of any environmental concerns related to lawn care. With a little effort and know-how, you can enjoy a lawn that will be the envy of your neighborhood!

Irrigation and Oklahoma

Dealing with the hot temperatures as of late, you may be wondering if your irrigation can keep up with the lack of rain and hot temperatures. Well, let’s take a little time to discuss your irrigation system.
First off, during drought conditions, always remember that your irrigation system was designed to supplement water to your lawn, not be the only source of moisture. This is, to some extent, why it may take longer watering times to deliver the moisture necessary to keep you turf green and your plants happy.
The easiest way to extend watering times with the current program is to use the seasonal adjustment setting on your modern timer. It will adjust all of the times for all of your zones in one simple step. (How to video HERE)
The next step is taking a little time to make sure your plants are getting enough water. Your bedding plants will be feeling the pressure from the lack of rain and high temperatures, but most species and especially established woody plants can be kept looking pretty good during these times of drought with a little supplemental watering. Just keep an eye on them to make sure they don’t look wilted from under or over watering.
As far as turf is concerned, make sure to keep enough water on any parts of your lawn that are Fescue. Any Fescue that dies is dead forever. Fescue will not go dormant like Bermuda and bounce back after it receives adequate moisture. In this respect, taking care of Fescue has a bit of a steep learning curve. Some die back will be inevitable year after year, however, with proper over-seeding, preferably slit seeding, each fall you should be able to easily replace Fescue that has died from normal attrition. Moving on to Bermuda, you’ve got a little easier task. Currently, most Bermuda lawns without irrigation are definitely showing some areas of dormancy. To bring Bermuda out of dormancy only requires consistent, substantial watering. On most lawns with typical irrigation systems we would recommend starting with 30 minutes on rotor zones for each area of Bermuda in full sun. Your watering can definitely come down some once we start to see cooler temperatures and substantial rainfall later this summer or early fall. Additionally, sandy soils that are unable to hold moisture may need even more water, or unfortunately, be unable to support Bermuda without watering at least daily.
