Fluctuating winter weather can have varying effects on your lawn, depending on the specific conditions. Below are some potential impacts.
It is rare that it gets cold enough to snow here in Texas, but on the off chance that snowfall occurs, it can act as a natural insulator, protecting your lawn from extreme cold as well as wind.
However, if temperatures fluctuate wildly, the melting and refreezing of snow can lead to ice formation, potentially damaging grass blades.
Thawing & Freezing Cycles
Rapid changes in temperature can cause the soil to alternate between thawing and freezing.
So, if temperatures drop below freezing at night and then rise during the day, the freeze-thaw cycle can expand and contract water in the soil.
This can lead to soil heaving, where plants are pushed up and out of the ground, which could damage grass roots as well as create air pockets in the soil.
Fluctuating temperatures can also affect moisture levels in the soil. Thawing can lead to increased soil moisture, which is beneficial.
However, if followed by rapid freezing, it can lead to soil compaction and potential root damage.
Most grasses go dormant during winter, slowing down their growth processes. Fluctuating temperatures could disrupt this dormancy, causing stress to the grass.
Snow Mold & fungal Diseases
This doesn’t seem to be as much of an issue in Texas.
Still, it’s worth a warning that extended snow cover periods, especially in fluctuating temperatures, can create conditions conducive to developing snow mold and other fungal diseases.
If there happen to be freeze-thaw cycles, it’s best to avoid walking on frozen grass. The blades are brittle during this time and can break, causing damage.
You can’t control the weather, but there are some things you can do to help the situation. The main issue in every situation is inconsistency.
5 Tips to Mitigate Potential Damage
A couple of things you can do to mitigate potential damage is follow the tips below to maintain consistency for the things you can control.
1. Limit Foot Traffic
This is one of the most important tips. Wait until the ground thaws before walking on the lawn to prevent damage.
2. Clear Debris
Remove any debris, such as leaves and branches, from the lawn to promote air circulation.
3. Maintain Proper Mowing Height
Before winter begins, ensure your grass is at the right height for your specific grass type.
Longer grass can provide some insulation and protection. If you need some tips on mowing heights, check out our mowing guide.
4. Aerate in Fall and Spring
Regular aeration encourages deep root growth and assists your grass in absorbing nutrients. Aerating in the fall is beneficial because it’s an active time of root growth.
If you forgot to schedule a fall aeration, make sure to schedule one for spring.
Once the ground thaws and temperatures stabilize, aerating your lawn will help alleviate any compaction that may have occurred during the winter.
5. Apply Fertilizer Carefully
If you choose to apply fertilizer alone, be cautious about timing and dosage, as excessive nutrients can harm your lawn.
It is always best to aerate first and then fertilize, as fertilizer focuses on feeding the root system, while aeration ensures more direct contact with the roots.

Winter Lawn Care
Remember, while winter weather can impact your lawn, it’s generally resilient and often recovers in the spring.
Regular maintenance practices and timely intervention can help minimize any potential damage.
