1. Maintain Your Lawn Health
Healthy grass will be far more resilient to hotter temperatures as the deep roots, and healthy leaves are better able to provide reserves of water. This means that lawn maintenance throughout the year is crucial to keeping your lawn looking green. If you’re unsure about lawn maintenance and care, you can seek advice from a local garden maintenance specialist.
2. Mow Frequently and High
In hotter weather, it is vital that you raise your lawn mower blades all the way to the top. While it may be tempting to crop the grass shorter, a longer leaf will help shade the soil and slow moisture loss. Longer grass will also be less resistant to drying out as it contains more moisture. So, plan for frequent mowing that will allow a fine mulch of grass clippings to remain on the soil surface and protect the moisture in your soil.
Many homeowners notice that the grass under garden benches and seating tends to stay green even in a heatwave, and this is because it is protected from the hottest parts of the day. So, if there are sections of your lawn that are prone to drying out and look brown, try to give them some shade. Set up a patio umbrella or move your garden table around, to keep those areas protected and looking much greener.
Dry, hot lawns can easily become hydrophobic where the soil will start to actually repel water. Rather than soaking in, the water will simply run off, which can compromise the root structures of your grass. Spiking or aerating your lawn will encourage water down into the root zone for more effective watering. It can also help to minimise compaction for a healthier lawn.
5. Reduce Your Lawn Feeding
When your lawn starts to look browner and unhealthy, your first instinct may be to reach for the lawn feed, but this can be a big mistake. Applying nitrogen in hot weather conditions may cause the dry grass to react. Water will be sucked out of the grass, causing it to be vulnerable to scorching. So, plan your summer feed program carefully with your landscaping company; using potassium based feeds, rather than nitrogen, or leave the feed altogether.
6. Keep Watering, Where Possible
The most common reason for lawns to go brown is that they dry out due to a lack of water. Since most of the homes in the Australia are on a water meter, many people try to conserve water use. Additionally, hosepipe bans quickly come into effect, which further compromises your ability to water. When you’re able to water your lawn, it is better to take a deep, infrequent approach. Allowing the soil to be thoroughly wet will encourage strong roots to prevent drying out. Trying to water shallowly can actually have the reverse effect, with shallow roots that are more vulnerable to drying out. To increase the effectiveness of your watering, try to do it early in the morning as this can slow transpiration water loss.
7. Consider Water Conserving Treatments
If you can water your garden, consider using a water conserving treatment. This will help your grass to use water in a more effective way, as the hydrophobic effects of the dry soil are broken down to prevent runoff. This type of treatment can be applied as a part of your typical lawn care routine.
If your lawn does start to look brown, don’t worry too much. Grass tends to be hardy and can bounce back when it begins to rain. If you do have concerns about your lawn, speak to your local landscape gardener for further help and guidance.
