Lawn aeration is one of the highest-impact things you can do for a garden — it punches small holes in the soil so water, nutrients, and oxygen can reach the roots instead of sitting on a sealed surface. The video above walks through the full process visually; the guide below gives you the steps in order so you can plan and execute with confidence. Whether you manage a private home garden, a holiday rental, or the grounds of a hotel in Greece, aerating once a year can transform a thin, patchy lawn into a dense, vibrant one.
Why Lawns in Greece Need Aeration
Greek summers are hard on lawns. Heavy clay soils common in many regions, combined with intense foot traffic around pools, terraces, and holiday rental grounds, compact the earth over time. Compacted soil prevents water from percolating down to the root zone, so even with regular irrigation the grass stays shallow-rooted and drought-stressed.
Aeration reverses this by physically opening up the soil profile. It also reduces thatch — the spongy mat of dead stems that builds up between the grass blades and the soil surface — which blocks water just as effectively as compaction.
Core Aeration vs. Spike Aeration
There are two main methods. Spike aeration uses solid tines to push holes into the soil, which is fast and cheap but can actually worsen compaction around each hole. Core aeration (also called plug aeration) uses hollow tines that extract a cylinder of soil and deposit it on the surface — the removed plugs allow the surrounding soil to expand and relieve pressure properly.
For most garden lawns, holiday rental outdoor spaces, and hotel grounds, core aeration is the right choice. The extracted plugs break down naturally within a week or two and return organic matter to the surface.
How to Aerate Your Lawn: 5 Steps
- 1
Water the lawn the day before
Aeration works best when the soil is moist but not waterlogged. Give the lawn a thorough watering 24 hours before you plan to aerate — roughly 25 to 30 mm. This softens the ground so the hollow tines can penetrate to their full depth (ideally 5–8 cm) and pull clean plugs rather than crumbling at the surface.
- 2
Mark or flag any obstacles
Walk the lawn and mark sprinkler heads, shallow irrigation lines, electric cables, or edging stones with small flags or bright spray paint. A core aerator is a heavy machine and will snap a plastic sprinkler head or damage irrigation lines if you drive over them. Taking five minutes to flag hazards prevents an expensive repair.
- 3
Make at least two overlapping passes
Set up your core aerator (rental machines are widely available) and make one pass across the entire lawn. Then turn 90 degrees and make a second pass perpendicular to the first. Overlapping passes in both directions ensures you pull plugs roughly every 8–10 cm across the surface — the density needed to genuinely relieve compaction rather than just poke a few random holes.
- 4
Leave the plugs on the surface
Resist the urge to rake up the soil plugs the machine deposits. Leave them in place. Within one to two weeks they will break down, return beneficial microbes and organic matter to the lawn, and help fill in the aeration holes naturally. This is an important part of the process — removing the plugs wastes most of the benefit.
- 5
Overseed and fertilise immediately after
Aeration creates the ideal moment to improve your lawn because the holes provide direct seed-to-soil contact and a clear path for fertiliser to reach the roots. Broadcast grass seed suited to the Greek climate (drought-tolerant Bermuda or tall fescue blends work well), apply a starter fertiliser, and water lightly every day for two weeks to establish new grass in the aeration channels.

FAQ
- When is the best time to aerate a lawn in Greece?
- For warm-season grasses such as Bermuda, the best window is late spring to early summer (May–June) when the grass is actively growing and can recover quickly. For cool-season grasses or mixed lawns in northern Greece, early autumn (September–October) works well because temperatures drop enough for strong root growth before winter.
- How often should I aerate my lawn?
- For most home gardens and rental properties with moderate foot traffic, once a year is sufficient. Lawns that see heavy use — poolside areas, children's play zones, hotel grounds — benefit from aerating twice a year, in spring and again in autumn, to stay ahead of compaction.
- Can I aerate a small lawn by hand instead of renting a machine?
- Yes. For lawns under roughly 50 square metres, a manual core aerator (a long-handled tool with two hollow tines) or even a garden fork pushed in at 15 cm intervals is practical. It takes more effort but produces the same result. For larger areas, renting a walk-behind core aerator for half a day is far more efficient and usually costs around €60–90 in Greece.
