Lawns could benefit from some care as the UK is about to enter the autumn period, when numerous weeds flourish and moss typically prospers. Kate Turner, a horticultural expert and gardening specialist from Love The Garden, has cautioned that weeds represent a frequent lawn irritation, and moss indicates poor turf condition stemming from problems such as poor drainage, too much shade, lack of nutrients, cutting grass excessively short, or constant foot traffic.
She said, “Moss in lawns is a sign that there is an underlying problem with the lawn. This can be caused by any of several factors, including poor drainage, shade, lack of fertiliser, [the] grass [being] cut too short or heavy foot traffic.” However, there’s no need to worry as there exists a simple solution for eliminating both weeds and moss, which also prevents moss from returning uninvited – that involves scarifying your turf. Scarifying is a technique aimed at eliminating the thatch layer that builds up gradually between the earth and grass on a lawn.
Thatch comprises different organic matter, including deceased grass, plant roots, foliage, and additional garden debris, which can prevent water, oxygen, and nutrients from reaching the earth, resulting in numerous turf issues.
Several of the most significant issues thatch creates include inadequate drainage, restricted root development, compressed earth, uneven grass coverage, heightened pest vulnerability, plus weeds and moss establishing themselves on your turf.
Scarifying a lawn is a straightforward procedure where you simply need to rake across the grass in spring and autumn, removing surplus thatch whilst helping to pull out weeds.
Kate explained: “If the moss and weed problem is mild, it may be possible to get on top of it by simply scarifying and then improving the overall health of the lawn with regular lawn care to stop the moss and weeds from coming back.”
She continued: “Always mow before scarifying and try not to be too vigorous in spring, only scarify until you can see soil underneath.”
While effective, scarifying lawns tears the grass plants in the process, leaving a bit of a mess. To fix this, it is recommended to overseed.
Overseeding is the process of laying fresh grass seed over an existing lawn to make it healthier and greener.
Replenishing your lawn like this also helps to add density, covering over bald patches that will accommodate weeds and moss.
To apply it, simply sprinkle on the seeds by hand and rake it into the soil — this ensures that the seed makes good contact with the earth, which it needs for germination.
While it’s not necessary to cover the seeds with soil, you do need to apply pressure to the seeds to ensure they stick to the soil for them to germinate.
Once the seeds are pressed into the soil, it’s time for a light watering. It’s better to water lightly three or four times a day than heavily once a day.
