Spring can be a challenging season for grass, as fluctuating temperatures, excess moisture, and emerging weeds can quickly take a toll on your lawn’s health. Proper spring lawn care is essential to set the stage for strong, healthy growth throughout the year. Come read our top tips for spring lawn care in Virginia to get your lawn care started the right way!
Before tackling any major lawn care tasks, it’s important to clear away the debris left behind from winter. If you had heavy snow or ice during the winter, check for signs of damage, such as compacted soil or dead spots, which may require extra attention later in the season. As snow and ice melt away, dead leaves, twigs, and other organic matter may have accumulated on your lawn, creating a barrier that blocks sunlight and restricts airflow. This layer of debris, often called "thatch," can trap moisture and create an ideal environment for mold, fungi, and pests.
Raking your lawn improves air circulation, promotes soil aeration, and allows sunlight to reach the grass, stimulating growth and recovery. Clearing debris also helps prevent the growth of mold and mildew, which can thrive in damp, shaded areas and damage your lawn.
Spring is the perfect time to test your soil and make necessary amendments. Virginia’s soil tends to be slightly acidic, particularly in areas with high clay content. If your soil pH is too low, grass struggles to absorb essential nutrients, leading to weak, patchy growth. Testing your soil early in the season ensures that any imbalances can be corrected before new growth takes off.
The ideal soil pH for most lawns falls between 6.0 and 7.0. If your test results indicate acidity below this range, applying lime will help neutralize the soil and improve nutrient uptake. Lime takes time to break down, so early spring application allows it to work before summer growth begins. Conversely, if your soil is too alkaline, adding sulfur can help lower the pH.
Compacted soil restricts air, water, and nutrients from reaching the grassroots, leading to poor growth and increased susceptibility to drought and disease. Aeration is a crucial step in alleviating compaction and encouraging deeper root growth. Aeration involves removing small plugs of soil to create space for air and moisture to penetrate.
The best time to aerate is early to mid-spring, once the soil has thawed and dried out enough to allow easy penetration. Core aerators, which remove small plugs of soil, are the most effective, but for minor compaction, a spike aerator can help. After aerating, applying a light layer of compost or topsoil can further improve soil structure and provide essential nutrients to the grass.
As grass comes out of dormancy, it needs proper nutrition to fuel new growth. Spring fertilization replenishes nutrients lost during winter and gives your lawn the energy boost it needs to develop strong roots and lush, green blades. Cool-season grasses, such as tall fescue and Kentucky bluegrass, benefit from an early to mid-spring fertilization.
A balanced fertilizer with nitrogen, phosphorus, and potassium (such as a 20-5-10 blend) encourages healthy top growth while strengthening the root system. Slow-release fertilizers are ideal because they provide consistent nutrients over time rather than causing a rapid growth surge that can weaken the lawn.
Spring is the prime time for weed prevention, as many common lawn weeds, including crabgrass, dandelions, and chickweed, begin to germinate as temperatures rise. Controlling weeds early prevents them from spreading and competing with your grass for nutrients, sunlight, and water.
One of the most effective ways to combat weeds is by applying a pre-emergent herbicide in early spring before weed seeds sprout. Pre-emergents create a barrier that stops weed seedlings from developing, reducing the need for extensive weed control later in the season. Timing is critical—apply pre-emergent when soil temperatures reach 55°F for several consecutive days, usually in late March or early April in Virginia.
The first mow of the season is an important step in setting the stage for a healthy lawn. In Virginia, grass typically starts growing actively in mid to late March. When mowing for the first time, set your mower to a height of 2.5 to 3.5 inches, depending on your grass type. Cutting too short can stress the grass and make it more vulnerable to weeds and disease.
Regular mowing throughout spring helps encourage thicker growth, but it's crucial to follow these mowing best practices:
Spring showers often provide enough moisture for lawns, but as temperatures warm up, monitoring your lawn’s hydration needs is essential. Overwatering can lead to shallow roots and increase the risk of disease, while underwatering can cause stress as the season progresses. The goal is to promote deep root growth by watering deeply but infrequently.
A good rule of thumb is to provide about one inch of water per week, either from rainfall or irrigation. Watering early in the morning (between 5 & 9 AM) reduces evaporation and allows the grass to dry out during the day, preventing fungal issues. Avoid frequent, light watering, as this encourages shallow roots that make grass more susceptible to drought.
