When your lawn is looking yellow, patchy or overgrown with weeds and moss, topdressing could be the solution. Topdressing a lawn refers to the process of applying materials over the lawn's surface. This gardening method has a lot of benefits, but the one it's most widely known for is producing stunning-looking lawns.

Gardening experts at Moowy recommend topping lawns with sand to "remedy heavily-stressed or poorly-nourished soil". Soils in poor condition are often too dense to allow root spread, so adding sand improves the pore size of your lawn soil. This helps water, nutrients, and oxygen penetrate the earth to feed your lawn's roots and get rid of any weeds and moss.

The pros claimed that you'll "see results from a single sanding". They explained, "You'll notice an improvement in your lawn's appearance due to the increased water, light, and nutrients. And over time, you'll see a thicker turf because the roots will have improved.

"In the long term, you'll notice your turf has looser topsoil and more dense, lush, and deep green leaves.

"You'll also see a more significant difference after applying lawn fertiliser, as your lawn becomes more capable of absorbing and holding onto nutrients."

The experts also pointed out that sand will "kill and prevent moss and weeds" from attacking your lawn.

It's worth noting that not all sand is good lawn sand. You want to avoid building sand and beach sand, as the chemicals or salt levels can kill your lawn.

The "ideal lawn sand" is a treatment mix of sand and iron sulphate. The ratio varies, but good mixes contain between 2% and 4% iron.

For most lawns, it is recommended to apply sand at least once a year. But if your soil is particularly heavy clay or stressed, apply lawn sand twice.

Avoid laying sand if you're due for heavy rainfall, as it'll wash the sand away. Choose a dry, warm day if you can.
