A healthy lawn starts below the surface. While many homeowners focus on fertilization and mowing, proper watering is often the difference between a lawn that thrives and one that struggles through a Minnesota summer.
In the Brainerd Lakes Area, sandy soils, changing rainfall patterns, and warm summer temperatures can make lawn watering a little tricky. At TurfCare, we regularly see lawns damaged not by too little water, but by watering the wrong way.
Water Deeply, Not Daily
One of the most common mistakes homeowners make is watering lightly every day. Frequent shallow watering encourages grass roots to stay close to the surface, making the lawn more vulnerable to drought, heat stress, and disease.
Instead, aim to provide approximately 1 inch of water per week, including rainfall. That water should usually be applied in one to three deeper watering sessions rather than a little bit every day. Deep watering encourages roots to grow farther into the soil, where moisture remains available longer during dry periods.
Water Early in the Morning
The best time to water your lawn is between 4:00 a.m. and 9:00 a.m.
Morning watering allows moisture to soak into the soil before the heat of the day causes evaporation. It also gives grass blades time to dry, reducing the risk of fungal disease that can develop when turf stays wet overnight.
Avoid watering during the afternoon when temperatures are highest, and avoid evening watering whenever possible.
Adjust for Brainerd Lakes Area Sandy Soils
Many lawns throughout the Brainerd Lakes region are built on sandy or sandy-loam soils. These soils drain quickly and do not hold moisture as long as heavier clay soils.
Because of this, some properties may benefit from watering more often than once per week, but still with enough water to reach the root zone. If water seems to move through the soil too quickly, consider splitting irrigation into shorter cycles with soak periods in between. This allows water to penetrate more effectively and helps reduce waste.
Know the Signs of Drought Stress
Grass often tells you when it needs water. Watch for these early signs of moisture stress:
- Footprints that remain visible after walking across the lawn
- Grass blades that fold or curl
- A bluish-gray tint to the turf
- Areas that appear wilted or dry
When these signs appear, your lawn may benefit from irrigation before the stress becomes more serious.
Keep Your Grass Taller
Proper mowing and proper watering go hand in hand.
Maintaining a mowing height of approximately 3 to 3.5 inches helps shade the soil, reduce evaporation, and encourage deeper root growth. Taller grass naturally conserves moisture better and often requires less frequent watering during the summer months.
Special Watering Guidelines for New Seed and Sod
Newly seeded lawns and fresh sod require different watering practices than established turf.
For new seed, the goal is to keep the soil surface consistently moist until germination occurs. This usually requires light, frequent watering for the first few weeks. Once the grass becomes established, gradually transition to deeper, less frequent watering.
New sod should receive thorough watering immediately after installation and remain consistently moist while roots establish. After rooting begins, watering frequency can be reduced while watering depth is increased.
The TurfCare Recommendation
For most established lawns in the Brainerd Lakes Area, TurfCare recommends the following watering practices:
- Water early in the morning, ideally between 4:00 a.m. and 9:00 a.m.
- Aim for about 1 inch of water per week, including rainfall
- Water deeply rather than lightly and frequently
- Adjust irrigation based on weather conditions
- Maintain mowing heights around 3 to 3.5 inches
- Monitor your lawn for signs of drought stress
Following these simple practices can help develop deeper roots, improve drought tolerance, and keep your lawn looking its best throughout the Minnesota summer.
