8 Tips for a Heatwave Healthy Lawn
The summer heat does no favours for the freshness of your lawn, leading to brown/yellow grass and areas of stunted growth. However, with these tips you can help retain grass moisture and ensure that your lawn remains green in colour.
Water your lawn in the mornings
Your lawn is likely to be dry in the morning, meaning that this is the most effective time to water your garden to reduce the evaporation loss from the summer heat. My advice is to ensure that you complete your watering by midday, or for better results before 9am. This should be carried out 2-3 times per week.
Avoid night watering
You may think that this is an optimum time to water your lawn, due to the lawn being dry and out of direct heat at night, but it will leave your garden more vulnerable to diseases and problems.
Invest in a sprinkler system
This will enable you to ensure that our garden is watered efficiently each morning, without having to worry about timings or completing the job manually. However, it is recommended that problem areas are watered by hand, as they may need more attention in extreme heat.
If temperatures exceed 30 degrees Celsius, it is necessary to hydrate your garden with around 5cm of water per week. If the soil is dry and hard, you grass will benefit from poking holes with a garden fork to help the water seep through.
Though it is necessary to note that too much water can make your lawn less drought-resistant in the case of extreme high temperatures or the risk of a hosepipe ban.
Mowing puts stress on your grass and weakens it, so mowing less regularly can help reduce this.
Leave grass trimmings
When mowing the leftover grass clippings can help to retain soil moisture by limiting the extent of evaporation from the surface. Smaller pieces evenly spread over the lawn will work better to achieve this.
Weeds will compete to attain the waters moisture with the grass, so it’s important to eliminate them if possible, leaving the grass with more hydration.
Carry out lawn repairs in the autumn
This will be after the extreme temperature fluctuations of summer heatwaves and adds stability for possible drought-like conditions in the next summer. Areas of scarcity will require over-seeding, but the use of weed killers on drought-affected lawns needs to be avoided.
