Sod Maintenance Tips

Sod Maintenance Tips for Iowa’s Climate

If you’re looking for sod maintenance tips for your new Iowa lawn, it’s important to take our local climate into account. Iowa is known for its hot, harsh summers as well as its brutally cold winters. With unpredictable temperate swings and fluctuation between heavy rain and drought periods, it’s essential to choose the right type of sod and learn to maintain it. Proper maintenance will help keep your sod strong, undamaged, and vibrant.

Understanding Iowa’s Climate and Soil Conditions

Iowa is a beautiful state, complete with acres of rolling hills and soil that is nutrient-rich and capable of growing a variety of crop types. That being said, there is a high prevalence of clay-heavy soils in Iowa, and only certain types of sod do well in a clay-rich environment.

This soil type combined with Iowa’s ever-changing climate makes for a potentially difficult combination when it comes to growing sod. With seasonal temperature extremes — ranging from polar temperatures in the winter, to excessive spring rainfall, to extreme summer heat — choosing the right type of sod and learning how to care for it is crucial.

Choosing the Right Sod for Iowa

The experts here at Siouxland Sod have been working with Iowa’s soil and climate for decades, which means we’ve spent a lot of time experimenting with and learning about sod types. We believe we’ve cracked the code in finding the best cool-season grasses to fit conditions in our state, which is why it’s so important to select sod from a local farm within your growing zone.

We specialize in the following grass types:

Tall Fescue: A cool-season grass that is able to withstand shade, high foot traffic, and the extreme temperatures of the midwestern climate. Its dense root system grows well in clay-heavy soil.

Kentucky Bluegrass: This high-density option can withstand the elements and can thrive in both shaded and full-sun environments.

Both of these options are blends, which we choose over single-variety sod due to the increased resilience and drought resistance that comes from blending grass varieties.

Watering Sod in Iowa

• Newly-installed sod can thrive in our climate and soil type, so long as proper watering protocols are followed.
• Water for 15-20 minutes, twice a day for the first 2 weeks after installation
• In the third week, transition to fewer watering times per week, but aim for longer, deeper watering sessions
• Adjust your watering based on weather conditions like heavy rain or drought periods
• 5 weeks after installation, begin watering in the early morning, between 6:00 and 10:00 am

Mowing Best Practices for Iowa Lawns

With cool-season grasses, basic mowing best-practices are all you need to maintain a lush, healthy sod lawn. Mow regularly and consistently, leaving the grass 2.5 to 3 inches high during the summer, and never cut more than one-third of the grass height at once. Consistent mowing helps with this.

Make sure your mower blades are sharp to avoid breakage and scalping, and avoid mowing your lawn during extreme heat or drought conditions. This reduces stress and encourages survival when the climate is adverse.

Fertilization and Nutrient Management

Fertilization can be done in Spring, Summer, and Fall, but the type of fertilizer varies depending on the time of year.

• Spring: Use balanced, slow-release fertilizer
• Summer: Use fertilizers designed to maintain growth, thickness, and color
• Fall: Use fertilizer with higher phosphorus and potassium for root growth

When temperatures are extremely high in the summer, it’s important to avoid over fertilization. Soil testing is a great way to determine your lawn’s fertilization needs, and we recommend you do that ___ times a year.

Weed, Pest, and Disease Control

In addition to proper watering and fertilizing, sod lawn owners have other natural elements to control.

Weeds: Some of the most common Iowa lawn weeds include dandelions, crab grass, clover, creeping Charlie, and broadleaf plantain.

Grubs and Insects: Grub worms and insects like ants, mole crickets, mosquitos and more can all have detrimental effects on your lawn. From biting and spreading disease to eating grass roots and destroying sod, it’s important to keep these controlled.

Fungal Disease: When temperatures rise along with humidity, grass and soil stay moist for long periods of time, skyrocketing the risk of fungal lawn disease.

Siouxland Sod encourages an integrated approach to these pest and disease risks, which requires local expertise and comprehensive strategy. We will work with you to assess your geographic location’s highest risks, and prescribe a plan for your lawn that keeps these natural threats at bay.

Aeration and Overseeding

Keeping a lawn thriving in our Iowa soil and climate requires certain maintenance methods that are simple, affordable, and effective. One of these methods is aeration — the process of coring small holes in your lawn’s soil. This mitigates compacted soil and improves root growth by allowing oxygen, water, and nutrients to flow more freely throughout your lawn.

After aeration, we recommend overseeding. In this process, grass seed is spread over the lawn after aeration in order to encourage growth and fill in any bare spots in your lawn.

Seasonal Sod Care Checklist

We know — this is a lot of information to keep track of! Here’s a handy checklist of the major seasonal maintenance milestones:

Spring

• Clean up your yard after the winter season
• Apply spring fertilizer; something balanced with slow release
• Apply pre-emergent weed control products

Summer

• Employ heat stress management throughout the summer, based on the weather. This can look like leaving your grass a little longer to shade the soil, and watering very early in the morning
• Adjust water based on precipitation levels. Water more in higher heat.

Fall

• Aeration
• Overseeding
• Fall fertilization – aim for high phosphorous and potassium levels

Winter

• Keep your lawn clean and free from debris and leaves
• Avoid foot traffic on frozen turf, as it can cause damage

10. Common Sod Maintenance Mistakes to Avoid

As you care for your lawn, be sure to avoid the following common sod maintenance mistakes:

Overwatering and underwatering: Underwatering is one of the leading causes of sod death, so it’s important to understand how much water your lawn needs by discussing this with your sod source. Overwatering, however, is also a common mistake. Look for puddling of water, “soggy soil,” and excessive runoff.

Cutting grass too short: Keep your lawn as close to ___ as possible. When you cut your grass too short, it puts excessive stress on the turf and interferes with successful growth.

Ignoring soil compaction: Soil compaction might not seem like a big deal, but overly compact soil impedes nutrient absorption, and hinders moisture distribution.

Fertilizing at the wrong time: Talk to your sod source about appropriate fertilization methods. Certain fertilizers should be used at certain times of the year for the best success.

11. When to Call a Professional

Many people are able to care for and maintain their sod lawns successfully without help, but there are times when the best choice is to call a professional. This protects your investment and prevents the loss of significant sections of your lawn. If you see signs of poor sod establishment — bare dirt patches, sudden weed overgrowth, grass discoloration — it’s time to call in an expert.

Other warning signs are persistent weeds and disease symptoms, and obvious water drainage issues. In these cases, you are best off contacting a professional, who will not only help you fix your issues, but teach you how to prevent them from happening in the future.
