Expert lawn care and maintenance services in London

A: In early spring, grass starts growing at an increased rate once the temperature rises above 5°C. You should consider mowing your lawn when the grass reaches 2.5 inches (above 6cm). Monitor its height—around 2.5 inches tall is the right height to mow after winter.

A: Mowing frequency depends on the season and how quickly your grass grows. During the growing season (spring to early autumn), mowing once a week is ideal for most lawns. In cooler months, or if growth slows, you can reduce it to every 2–4 weeks. Our gardeners can recommend a custom schedule based on your lawn’s condition and the time of year.

A: The ideal length for cutting grass in the UK is around 25mm. Cutting it shorter can stress the grass and lead to patchiness. During hot or dry weather, it’s best to raise the cutting height slightly to help retain moisture and keep your lawn green and healthy.

A: To retain a healthy, green appearance your lawn should not be mowed less than 25mm in height. During warm, dry periods you should increase the height of cut to retain moisture and a green appearance.

A: If you wish to keep your lawn green during drought it may be necessary to apply water. This is best done in the early morning or last thing in the evening using a sprinkler.

A: We recommend that you don't cut your lawn for 3 days either side of any treatment. This is to ensure that we can see the weeds and the treatment of them has a couple of days to reach the roots.

A: Absolutely. The gardener will, first, trim the grass and then, he’ll cut it with a professional petrol lawn mower.

A: Repairing a badly damaged lawn typically involves several steps. First, we assess the damage and remove dead grass or thatch through scarification. Next, aeration improves soil structure and allows nutrients to reach the roots. Overseeding helps restore bare patches, followed by top-dressing to support new growth. Regular mowing and fertilising complete the recovery process. Our team will tailor the treatment to your lawn’s specific needs for the best results.

A: Repairing a lawn overrun with weeds and moss involves several key steps. First, scarification removes moss and thatch buildup. Then, aeration helps improve soil health and drainage. Following that, overseeding fills in bare patches with healthy grass, while fertilising strengthens new growth and discourages weed regrowth. Our lawn care specialists can create a tailored treatment plan to restore your lawn and keep it healthy long-term.

A: Uneven lawns can often be improved without full levelling. Common solutions include top-dressing, where a mix of topsoil and sand is applied to low spots, and aeration, which helps relieve compacted soil. If the unevenness is severe, more extensive lawn repairs or turfing may be recommended. Our gardeners will assess your lawn and suggest the best approach to restore a level, healthy surface.

A: Common signs of an unhealthy lawn include yellowing or thinning grass, bare or patchy areas, moss or weed overgrowth, spongy or compacted soil, and slow or uneven growth. If you notice any of these issues, our professional gardeners can assess your lawn and recommend the right treatment to restore its health and appearance.

A: Signs of lawn disease include discoloured patches (yellow, brown, or grey), mould or mildew on the grass blades, thinning areas, and rapid spreading damage despite regular care. Common lawn diseases in the UK include red thread, fusarium patch, and dollar spot. If you suspect your lawn may be diseased, our professional gardeners can inspect the area, identify the issue, and recommend the right treatment to restore its health.

A: Treating lawn disease starts with correctly identifying the issue. Depending on the type (such as red thread, fusarium patch, or snow mould), treatment may include improving drainage, adjusting mowing habits, applying the right fertiliser, or using a fungicide. Our professional gardeners can assess your lawn, determine the cause, and apply targeted treatments to stop the disease and restore healthy growth.

A: Random patches of dying grass can be caused by a variety of issues, including pet urine, fungal diseases, pests, poor drainage, compacted soil, or uneven fertiliser application. Environmental stress like excess shade or drought can also create patchy damage. Our lawn care specialists can identify the root cause during a site visit and apply the right treatment, whether that’s overseeding, aeration, or targeted repair.

A: A lawn may look worse after mowing for several reasons. Common causes include cutting the grass too short (scalping), using dull mower blades that tear rather than cut, mowing when the grass is wet, or mowing too infrequently. These mistakes can stress the grass and lead to discolouration, uneven growth, or bald patches. Our professional gardeners use sharp, well-maintained equipment and apply best practices to keep your lawn healthy and looking its best after every cut.

A: If your grass looks worse after fertilising, it could be due to over-application, using the wrong type of fertiliser, or applying it in the wrong weather conditions. Over-fertilising can “burn” the grass, causing yellow or brown patches. Uneven spreading may also lead to patchy growth. Our lawn care experts assess your lawn and apply the correct type and amount of fertiliser at the right time, helping avoid these common mistakes and ensuring healthy, consistent results.

A: One of the most common mistakes is mowing the lawn too short, which stresses the grass and makes it more vulnerable to weeds and drought. Other frequent issues include overwatering, using the wrong fertiliser for the season, and applying treatments without proper timing. Our professional lawn care team ensures every step is done correctly to promote healthy, lasting growth.

A: You should begin to notice a difference within 12–16 days of your first treatment. Of course, some treatments, such as scarification, will show immediate results. Your lawn will then improve over the course of the treatments.

A: Lawn treatment frequency depends on the season and the specific needs of your grass. Mowing is usually done weekly or fortnightly during the growing season. Fertilising is best done 2–4 times a year depending on the grass type. Aeration and scarification are typically done once or twice a year (spring and/or autumn). Overseeding may be needed annually or after lawn damage. Our gardeners can assess your lawn and recommend a custom maintenance schedule to keep it healthy year-round.

A: The cost to level a lawn depends on the severity of the unevenness, the size of the area, and whether soil or turf is needed. While we don’t currently offer full-scale lawn levelling as a standalone service, related treatments like top-dressing and overseeding can help smooth out minor uneven areas. You can discuss your lawn’s condition with our gardeners during your on-site visit for tailored recommendations.

A: The cost of turfing a garden depends on the size of the area, the type of turf selected, and whether any ground preparation is needed beforehand. While turfing is not included in our standard lawn maintenance service, we may be able to assist with turf installation or refer you to our landscaping team. If you're unsure whether your lawn needs turfing or can be revived, our gardeners can assess it during a site visit.

A: Yes, our professional lawn care service is performed by skilled local gardeners, who are fully equipped with all the tools and machinery, required for the job.

A: The gardeners can work in most weather conditions and usually this doesn't affect the job results. However, bear in mind that lawn mowing when the grass is wet will damage the lawn.
