Make every drop of water count

6th Jun 2020

Most parts of the UK have had a stunning spring weather-wise. Following the wettest February on record, weeks of blue skies, clear air and warm sunshine have been a much welcomed distraction during a period of such uncertainty for the whole nation. May was the sunniest calendar month on record and also one of the driest, so it’s unsurprising that lawns are starting to feel the effects.

Adding wetting agent to your treatment plan

Improved water infiltration

When there’s little or no rainfall for a prolonged period of time, lawns can become stressed and start turning brown. When it rains we expect it to help, but sometimes the soil becomes so dry it becomes water-repellent and moisture is unable to move down through the soil profile.

The result of hydrophobic soil is pooling of surface water, which is counterproductive in that it cannot be taken up by the plant and it evaporates. Dry Patch is a common occurrence as hydrophobic soil becomes difficult to re-wet. To help make the most of the rainfall, we can apply a penetrant wetting agent to your lawn. Wetting agents reduce the surface tension of water to promote infiltration and penetration deeper into the soil profile, then when it rains or you use a sprinkler, all the moisture is put to good use by the grass plant and none is wasted. Our wetting agent can be applied at any time, including at the same time as your feed and weed treatment. Please ask your local Lawn Master for more information.

Hold back on the mowing

Keeping your grass a little longer in the summer helps it cope better with dry conditions.

Quench its thirst the right way

It’s surprising how quickly lawns dry out. If there’s no rainfall, it’s essential to water your lawn if you want to maintain its green colour. The most beneficial and economical time to water is early in the morning before it gets hot. Watering in the heat of the day is wasteful and ineffective as the moisture simply evaporates.

If you have a sandy soil lawn, you will typically need to water more and sooner during dry conditions. Those with heavy clay soil will not have to water as quickly or as frequently because clay does not drain as quickly as sand.

Different areas of your lawn will fare better in the heat, so spot watering may be a good option. Areas around trees and shrubs dry out quicker as their roots take up a lot of available moisture from the soil. Lawn in shaded areas will typically retain moisture longer because it is not in as much direct sunlight.

If you choose not to water your lawn over the summer, the grass will turn brown but it is not dead; it becomes dormant and the green colour will gradually return once rainfall returns to normal levels.

Clear the decks

Try to move garden furniture and children’s toys off the lawn when they’re not in use to give the grass exposure to sunlight, air flow and rainfall. It will help prevent it yellowing and dying off.

If we’re treating your lawn, speak with your local Lawn Master who will be happy to discuss the best way to manage your lawn over the summer. If you’re not yet a customer and your lawn’s letting your garden down, here’s how to get started.
