ᐅ Burnt Lawn – Can Water Retention Granules Help?

Hello,

we currently have a problem with the grass edges along the roadside burning. This is partly due to the concrete base underneath, which drains water underground, and partly because the grass edge stones/the road heat up, causing increased evaporation. Watering only helps to a limited extent because the concrete base means there is only a small amount of soil and therefore limited water capacity.

Many people in this housing development have the same issue and solve it by removing the grass, for example, and creating a gravel bed or something similar, or they have simply accepted the situation.

Are there other solutions? Would moisture-retaining granules possibly help?

We will then try using a primer plus a two-component waterproofing slurry. Especially in the areas where we have a metal lawn edging and the concrete wedge therefore reaches close to the top edge of the topsoil.

In 1 to 2 years, I might be able to say whether it makes a difference.

Installing moss is also green and retains moisture very effectively

Update 2023: no effect; the lawn still dried out. Although the waterproofing prevents the concrete from absorbing moisture, the heat exposure still damages the lawn edges reliably 😉 However, it only happens for a few months in autumn and spring again.

Sealing helps but is not enough. In areas with heavier watering, water more frequently or bury a drip irrigation hose.

You might have already thought of my idea and dismissed it for good reasons:
Since we greened our garage roof, I’ve become quite a fan of sedum (until then, I always thought sedum was unattractive). However, we only planted the sedum trays in May, so I don’t yet know how the different sedum varieties will look in autumn, winter, and spring.
