Lawn watering & irrigation

Understanding Lawn Needs in Drought Conditions: During the summer, particularly in prolonged dry spells, maintaining your lawn’s lushness requires careful consideration of its watering needs. While a typical British summer often brings enough rainfall to sustain lawns, extended dry periods demand supplemental watering. The frequency and amount of water required depend on factors like soil type, grass variety, and mowing height.

For instance, a lawn with heavy clay soil, sown with ryegrass and mowed at 25mm, will be more resilient in drought compared to a finely mowed lawn on sandy soil. Consequently, every lawn has its unique watering needs.

Drought Preparedness for Your Lawn:

  1. Combatting Dry Patches: Summer can bring about ‘dry patch’ issues. This occurs when soil becomes excessively dry, turning water-repellent, leading to grass loss. Though we can’t control the UK’s weather, we can adopt strategies to foster a robust root system and nurture drought-tolerant grass varieties.
  2. Aeration: Aeration creates pathways in the root zone, promoting deeper rooting for healthier grass. It also alleviates soil compaction. For detailed insights, refer to our aeration guide.
  3. Top Dressing: Following aeration, top dressing fills the created channels, providing an optimal environment for root growth. This is particularly effective post hollow tining.
  4. Nurturing Drought-Resilient Grass: Proper lawn care and management can foster grass varieties better equipped to handle drought. This includes judicious use of fertilizers and water to prevent overfeeding and overwatering.
  5. Adjusting Mowing Height: Elevating your mower’s cutting height can reduce the drought-induced stress on the grass. Ensuring sharp mower blades also aids in faster grass recovery post-mowing.

Deciding When to Water:

Hold off on immediate watering at the first sign of summer dryness. A slight dryness can actually benefit your lawn by encouraging root depth as they seek moisture. However, don’t wait until the lawn turns entirely yellow or brown. Watering becomes essential when the grass shifts from a vibrant green to a blueish-grey tone. Using a soil sampler can help gauge root zone moisture levels. If the soil feels extremely dry or hard, consider light spiking before watering to aid water absorption.

Determining Watering Frequency:

Lawn irrigation lacks a one-size-fits-all approach. Ideally, deeply water once a week, allowing the root zone to somewhat dry between sessions. Yet, in intense heat, more frequent watering might be necessary. Note that sandy soils dry faster than clayey counterparts, demanding more water. It’s crucial to avoid shallow, frequent watering, which can result in overhydration and foster shallow-rooted grasses.

In summary, understanding your lawn’s unique requirements and adjusting care techniques accordingly ensures its health and vitality, even in challenging drought conditions.
