1. Start early.

Established weeds can be eliminated, but by the time they appear, significant damage has already been done. Crabgrass growth robs turf of valuable nutrients and moisture, forcing it to struggle for survival. By preventing most weed seeds from germinating, the turf can grow in thicker and healthier.

• Timing is critical: Crabgrass seeds begin to germinate when soil temperatures consistently reach 55°F for a few days, typically in early spring. Applying a high-quality pre-emergent herbicide before this threshold creates a protective barrier, stopping weed seeds from taking root. At HillSide, we pair this pre-emergent application with our first fertilization treatment, ensuring your lawn gets both weed protection and the nutrients it needs for strong, early-season growth.
• Don’t skimp on quality: HillSide’s early spring pre-emergent weed control application is one of the most effective and long-lasting solutions for preventing crabgrass infestations. By eliminating weed competition before it starts and providing essential fertilization at the same time, your lawn retains more nutrients, moisture, and space to grow in thicker, healthier, and more resilient against drought, heat, and foot traffic.

2. Prepare your soil.

Spring is the ideal time to assess soil health. Proper preparation ensures your lawn gets the nutrients and care it needs to thrive, including:

• Soil testing: A soil test helps identify imbalances in pH and nutrient levels so that proper fertilizers or amendments can be applied.
• Evaluation: An assessment of the texture and structure of your soil will determine if it’s compacted. Healthy soil should drain well but retain enough moisture for grass roots to thrive.

3. Mow the right way.

Mowing does more than just keep your lawn tidy; it’s a crucial step in promoting health and vibrance. Although HillSide does not provide mowing services, we recommend the following:

• Mow at the right height: Mowing at approximately 4 inches allows for taller grass blades that shade the soil, preventing crabgrass germination and reducing stress on the grass.
• Sharpen your blades: Dull mower blades can tear grass, exposing it to disease and discoloration. Keep mower blades sharp for clean, healthy cuts.
• Mow when dry: Mowing wet grass leads to clumping and uneven cuts, which can harm your lawn.

4. Feed regularly.

A thick, lush lawn seldom contains crabgrass because there’s simply no room for it. HillSide’s lawn care programs follow an optimum feeding regimen. Feeding your grass properly helps it grow strong and resistant to stressors, especially when summer heat arrives. Follow these tips:

• Tailored nutrients: A soil test will reveal what your lawn needs. The main nutrients—nitrogen, phosphorus, and potassium—should be applied in balanced amounts for healthy growth.
• Choose safety and quality: HillSide Lawn Service is committed to quality products and environmentally friendly practices. Our fertilizer program complies with Maryland nutrient management regulations.
• Timing matters: Apply fertilizer once your lawn is actively growing in the spring. Depending on the weather and grass type, the timing may vary.
• Application is important: To ensure an even spread, use a broadcast spreader and follow recommended application rates to avoid over or under-fertilizing.

5. Rely on deep watering.

Weeds thrive in tough conditions, often outcompeting lawn grass when moisture is inconsistent. Frequent, shallow watering encourages weak, shallow root growth, making your lawn more susceptible to weeds. Instead, focus on deep and infrequent watering, ensuring moisture penetrates at least six inches deep into the soil. This approach promotes stronger, deeper roots, helping grass resist drought stress and outcompete weeds naturally. Timing matters, too:

• Water in the early morning: This reduces evaporation and allows grass to absorb moisture before the heat of the day.
• Avoid evening watering: Wet grass overnight increases the risk of fungal diseases.
