Lawn Care Calendar: What to Do Each Season in the South East

Spring: wake the lawn up carefully

Spring is about assessment first, then light corrective work. Do not rush in with heavy feeding, aggressive raking or very short mowing as soon as the weather improves. Wait until the grass is actively growing and the ground is not saturated.

Start by walking the lawn and checking for thinning patches, moss, standing water, bare areas near paths, and compacted ground where people regularly step off patios or side returns. In London and Surrey, smaller lawns in terraced and semi-detached properties often suffer most around edges, under fences, and in shaded corners where airflow is poor.

Your first few cuts should be gentle. Set the mower higher than usual and remove no more than a third of the grass blade in one go. Cutting too low early in the season weakens the lawn and opens up space for moss and weeds.

• Rake out winter debris such as leaves, twigs and surface moss by hand or with a light spring-tine rake
• Mow only when the lawn is dry enough to avoid smearing the surface and compacting the soil
• Re-seed bare patches once temperatures are consistently mild and the soil has warmed
• Check lawn edges against beds and paths, as broken edges often make a lawn look untidy even when the grass is healthy
• If water sits on the surface for more than a day after rain, note the area for later drainage or soil improvement work

Summer: mow properly and water with purpose

Summer lawn care is mainly about avoiding stress. The most common mistake is cutting too short during hot or dry spells. Slightly longer grass shades the soil, slows moisture loss and helps the lawn cope better with heat and foot traffic.

Watering is useful, but only if done properly. Frequent light watering encourages shallow roots and a weaker lawn. A thorough soak less often is better, ideally early in the morning so water can reach the soil before the day heats up.

Small urban gardens and flat conversions can have awkward access to taps, limited hose storage and uneven exposure to sun and shade. In these settings, it often makes more sense to accept that one part of the lawn will perform differently from another, rather than trying to force a uniform finish across the whole space.

• Raise the mowing height in hot weather rather than trying to keep the lawn very short
• Leave off mowing altogether during severe drought if the grass is not growing
• Water early in the morning, not in the middle of the day or late evening
• Watch for pale grey-green colour, folded blades and lingering footprints, which are early signs of drought stress
• Move paddling pools, furniture and planters regularly to avoid yellow patches and dead circles

Autumn: the most important season for repair

For most lawns in the South East, autumn is the best time to make real improvements. The soil is still warm, rainfall is usually more reliable, and grass can establish without the heat stress of summer. If your lawn has been thin, mossy or patchy all year, this is the season to act.

This is the point to deal with compaction, poor surface levels and bare areas. Lawns in older London and Surrey gardens are often built on tired, compacted ground or disturbed soil from past building work, extensions or utility repairs. If those underlying issues are not addressed, re-seeding alone rarely gives a lasting result.

Regular leaf clearance matters in autumn, especially in gardens bordered by mature trees. Wet leaves left sitting on the grass block light, trap moisture and encourage disease and dieback.

• Aerate compacted areas to improve airflow, drainage and root growth
• Overseed thin sections while the soil is still warm enough for germination
• Top-dress uneven or worn patches lightly rather than burying the existing grass
• Keep leaves cleared from the lawn and from drainage channels around patios and paths
• Plan any fencing repairs or replacement before winter if shade, wear or poor boundaries are affecting the lawn

Winter: protect the lawn by doing less

Winter is usually the season to leave the lawn alone as much as possible. Grass growth slows sharply, the soil stays wetter for longer, and foot traffic causes far more damage than it does in drier months. Repeated use of the same route can leave compacted stripes and muddy areas that take months to recover.

Avoid mowing unless conditions are unusually mild and the lawn is clearly still growing. Even then, keep the cut light. Never mow frozen grass, and do not walk repeatedly over frosty lawns, as the blades can be physically damaged when frozen.

This is also the time to observe rather than intervene. Watch where water collects, which edges stay waterlogged, and whether certain spots remain bare or mossy. Those winter patterns tell you what to tackle properly in spring or autumn.

• Keep off the lawn during frosty mornings where possible
• Use stepping stones or a temporary route if access across the grass is unavoidable
• Remove debris after storms, but avoid heavy raking on wet ground
• Clear gutters, downpipes and nearby drains if overflow is contributing to lawn saturation

When to deal with it yourself and when to call a professional

Basic seasonal mowing, light raking, leaf clearance, small patch repairs and sensible watering are all realistic jobs for most homeowners. The key is to stay consistent and avoid heavy-handed fixes. Many lawn problems get worse because too much is done at the wrong time rather than too little.

Professional help is worth considering when the issue goes beyond routine maintenance. Persistent standing water, widespread moss, severe compaction, repeated bare patches, poor levels, heavy shade, or damage linked to fencing, drainage or access usually need a broader solution.

For London and Surrey homes, practical factors matter as well. Small gardens, narrow side access, shared entrances, on-street parking and limited storage can all make larger garden jobs harder to manage yourself. CS Services can help with garden maintenance, planting and fencing, with bespoke, no-obligation quotes and the scope agreed before work starts.

• DIY is suitable for regular mowing, light seasonal tidying and minor patch seeding
• Call a professional if the lawn stays wet for long periods or deteriorates in the same places every year
• Ask for help if neighbouring trees, broken fencing, compacted access routes or garden layout are part of the problem
• Use regular maintenance if you want the lawn kept in order without having to manage every seasonal task yourself
