Optimizing Your Lawn Care: Dormant or Watered During Summer

As the temperatures rise in summertime, the decision on whether to water your grass or let it go dormant might seem like a protracted debate. This article explores the best practices and potential outcomes of each approach, aiming to help you make an informed choice with the well-being of your lawn as the ultimate goal.

Understanding Summer Grass Care

The summer season brings warm temperatures and varying levels of humidity, which can significantly impact your lawn's health and appearance. Grass goes through different phases, and depending on its maturity and the local weather conditions, you might find yourself deciding whether to water your lawn or let it naturally go dormant.

Letting Your Lawn Go Dormant

Many seasoned gardeners and lawn enthusiasts recommend letting your lawn go dormant during hot summer weather. Dormancy is a natural process that allows grass to conserve energy and water during periods of extreme dryness.

Pros of Dormancy:

Water Conservation: When grass goes dormant, it doesn't require as much water, which can save you a significant amount of money and resources. For example, watering a modest lawn may cost around $150 per month, which can be a considerable sum. Environmental Benefits: Reducing the amount of water used during summer helps preserve groundwater and supports overall sustainability. Reduced Pest and Fungal Problems: Dormant grass is less susceptible to pests and diseases that thrive in moist environments, leading to healthier grass overall.

However, it's important to understand that not all lawns are alike, and the decision to let your lawn go dormant depends on several factors.

When to Water Your Lawn

While dormancy can be beneficial, there are times when your grass requires water, particularly when it's a new lawn. Here are some key factors to consider:

1. New Establishment: New lawns have shallow and underdeveloped root systems, making them more susceptible to the harsh conditions of summer. Without proper hydration, they may struggle to survive.

2. Adjusting to Summer Weather: Established lawns may be able to go dormant, but the transition period can be challenging. Watering during this period can help the grass transition smoothly into dormancy.

Watering Guidelines:

Quantity: Water deeply but infrequently. Aim for about one inch of water per week. This encourages the grass to develop a deep root system, essential for resilience. Schedule: Water early in the morning to reduce water loss due to evaporation and to minimize stress on the grass. Avoid watering during the heat of the day or in the evening to prevent fungal growth. Quality: Use rainwater if possible, as it is often free of harmful chemicals and pollutants. If tap water is your only option, ensure it is safe to use by checking for any water bans or restrictions.

Consequences of Overwatering

Overwatering during the hot summer months can lead to several negative outcomes:

Eroded Soil: Excess water can lead to soil erosion, reducing the nutrients available to the grass and making the lawn more susceptible to damage. Increased Moisture: More moisture in the soil can create a breeding ground for pests and fungi, leading to potential disease issues. Water Waste: Overwatering can result in significant financial costs and an unnecessary waste of a valuable resource, especially in drought-prone regions.

During the 2022 drought in Southeast England, it was crucial to manage water resources carefully. The implementation of hosepipe bans highlighted the importance of efficient water usage. However, once the rains returned, the grass quickly recovered, showcasing the resilience of properly maintained lawns.

Conclusion

Deciding whether to water your grass in summertime or let it go dormant is a multifaceted issue. Both approaches have their merits, but the key is to make a choice based on your lawn's maturity, local weather conditions, and long-term sustainability goals. By understanding the implications of each option, you can ensure that your lawn remains healthy and vibrant throughout the changing seasons.
