In the face of drought, the wise approach to lawn care is to embrace minimalism, according to Daniel Sandor, an assistant professor of turf grass science at Virginia Tech. Sandor's advice is a refreshing take on a common dilemma for homeowners in the D.C. region, where moderate to severe droughts are currently plaguing the area. His recommendation to 'do as little as possible' is not just a catchy phrase but a strategic move to help your lawn survive and thrive during these challenging times.
The focus should be on reducing stress on the grass, especially for those cool-season grasses like fescue and bluegrass that are particularly susceptible to drought stress. One of the primary stressors is mowing, so Sandor suggests raising the mowing height to at least three inches, or as high as your mower will go. This simple adjustment allows the grass to grow longer, which in turn encourages deeper root growth. Deeper roots mean the grass can access water at greater depths, making it more resilient during droughts.
The 'one-third' rule is another crucial tip. Sandor advises against cutting more than one-third of the grass blade in a single mow. This practice helps maintain the grass's health and strength, ensuring it can withstand the stress of drought. By mowing less frequently and higher, you're essentially giving the grass a break, allowing it to conserve energy and focus on survival.
Fertilizer, a common go-to for struggling lawns, should be avoided during droughts. Sandor explains that when the soil is dry, fertilizers struggle to break down and release nutrients. The grass needs to conserve its energy, and adding fertilizers can further strain an already stressed system. Instead, Sandor recommends waiting until fall, when root growth is more active and the soil is more conducive to nutrient absorption.
While it might be tempting to host backyard gatherings on the grass during droughts, Sandor suggests proceeding with caution. The extra foot traffic can add stress to the lawn, but he reassures that the grass will recover once rain returns. The key is to strike a balance between enjoying your outdoor space and giving the lawn time to rest and recover.
Looking ahead, Sandor's advice for next year involves a proactive approach. Fertilizing in the fall and conducting regular soil tests every three years are essential steps to ensure the lawn is well-prepared for the drought season. This proactive approach not only helps the grass during active growth periods but also significantly improves its drought resistance over time.
In the words of Sandor, 'Do as little as possible' is not just a mantra but a strategy for lawn survival. By embracing this minimalist approach, homeowners can help their grass endure the challenges of drought, ensuring a healthier and more resilient lawn in the long run.
