Fertilizing Your Sod: A Key to Thickness and Vibrancy
One of the most important aspects of maintaining your sod’s quality in Utah is regular fertilization. While new sod has a strong initial root system, continued fertilizing throughout the season ensures your grass stays healthy and lush. In Utah’s climate, where soil quality is usually below average, fertilizing at least four times per season is essential.
- Early Spring: Start the growing season with a balanced fertilizer that includes both nitrogen and phosphorus to help your sod establish strong roots after the winter.
- Late Spring: As your grass starts to grow actively, switch to a nitrogen-rich fertilizer to promote vibrant, thick growth. 24-5-10 + 5% XRT Fe
- Mid-Summer: Continue using a high nitrogen fertilizer like 19-3-5 + 5% XRT Fe to maintain steady growth during the hotter months, ensuring your grass doesn’t go dormant too early.
- Fall: A final feeding in early fall helps your sod prepare for winter by providing necessary nutrients to sustain it through the cold months.
By following a consistent fertilization schedule, your sod will not only stay thick and green, but it will also be better equipped to resist stress from heat, drought, and foot traffic.
Training Your Sod With Water: Deep Roots Are Essential For Drought Resistant Lawns
Proper watering is critical for the long-term health of your sod, especially in Utah’s dry climate. While it may be tempting to water frequently, this can lead to shallow root systems that struggle to endure heat and drought. The goal is to promote deep, resilient roots that can access water more efficiently.
Heavy, Infrequent Watering: Watering deeply but less often is the key to establishing deep roots. Typically, sod requires about 1 to 1.5 inches of water per week, but this can vary depending on the grass type, weather conditions, and soil texture. The rule of thumb is to water deeply enough so that the moisture reaches the root zone (about 6 to 8 inches deep for most grasses). Roots will chase water deeper and deeper into the soil over time, eventually pulling water from soil deep enough to stay fairly moist throughout the day. During hot periods, increase your watering intervals if needed, but be mindful not to overdo it.
Irrigation Audits for Efficiency: Maximizing water efficiency should be a priority in Utah, where water conservation is crucial. Conducting and irrigation audits helps ensure that your system is working optimally. Look for any areas where water may be wasted, such as sprinklers that are broken or improperly adjusted, or areas where water is pooling or running off. Fine-tuning your system can save you money, conserve water, and keep your sod healthy by delivering the right amount of water where it’s needed most.

Avoiding Overwatering: While water is essential for your sod’s health, overwatering can lead to root rot, fungal diseases, and nutrient leaching. Avoid watering too frequently or at the wrong times of day. Early morning or late evening watering is best to reduce evaporation and ensure that water has time to soak into the soil before the sun heats up.
Mowing: Keep It Sharp and Frequent
Mowing may seem like a simple task, but it plays a significant role in maintaining sod health. Regular mowing encourages new growth, helps your sod fill in thicker, reduces the chances of pest and diseases, and reduces weeds.
Keep the Mower Blade Sharp: A dull mower blade can tear grass instead of cutting it cleanly, which can stress the sod and make it more vulnerable to disease and pests. Make sure your mower blade is sharpened regularly. A clean cut helps your sod heal more quickly and improves water holding capacity.
Mow Frequently: During the growing season, mowing your lawn regularly (about twice a week during peak growth) helps prevent the grass from becoming too tall. Taller grass can become prone to pests, diseases, and may even suffer from nutrient deficiencies. Aim to cut no more than one-third of the grass height at a time to avoid stressing the grass.
Avoid Cutting Too Short: For many sod varieties in Utah, keeping the grass height around 2.5 to 3 inches is ideal. Mowing too short can stress the grass, reduce its ability to photosynthesize, and encourage weed growth. Leave the grass a bit taller during the hotter months to help it retain moisture and shade the soil.
The Bottom Line: Consistency is Key
Maintaining high-quality sod in Utah requires consistent attention to detail. Regular fertilization, efficient watering practices, proper mowing, and other upkeep practices work together to keep your lawn thick, green, and healthy. By committing to a routine of deep watering, frequent mowing, and strategic fertilization, you’ll not only boost the aesthetic appeal of your yard but also improve its long-term sustainability—making it more resistant to stress from heat, drought, and disease.
By focusing on these fundamental practices, you ensure that your sod thrives year after year, helping to conserve water, reduce maintenance, and create a lawn that enhances your home and community. Whether you’re a new sod owner or someone looking to improve an established lawn, maintaining the health of your grass is one of the best investments you can make for your landscape’s future.
