When Can I Mow My Lawn After Seeding?

Over time lawns can become thin and patchy, this is down to a number of reasons whether it is excessive wear and tear or a result of insect or fungal attack. Lawns can often need thickening up to improve their appearance and will benefit from seeding or over-seeding. When this process has been carried out it is time to think about how to maintain it and when to start mowing to help develop it into the lush green and healthy lawn that you dream of.

As a professional lawn care company we carry out a variety of services when we seed our customer’s lawns. We may start a lawn from scratch with bare soil, or carry out a renovation which will include aeration and seeding. We love lawn care and we know that the correct over-seeding on a lawn is critical to how it grows and develops into a lush green and healthy lawn.

A common question that lawn owners ask us either before they have their lawns seeded or afterwards is “Can I mow my lawn after seeding and when?” After all they don’t want to damage their lawn after investing time and money into getting it into great shape.

Newly seeded lawnWe want to give you great advice when it comes to lawn care and we would recommend following these guidelines after your lawn has been seeded.


  •  Leave your newly seeded lawn for at least two weeks, and longer if possible, before you attempt to mow it. This will allow the new seed time to develop roots

  •  Mow newly seeded areas at approximately 3” high from the first 4-6 weeks after the seeds have germinated – This means mowing a little higher than usual. If grass blades  are a little taller it will help retain moisture as they will shade the soil better.

  •  If you have a large area to mow, where possible try to use a walk-behind lawn mower for the first month after new grass germinates – It may take a little more time and effort,  but if you do this for a couple of mowings it will really benefit and help your new lawn establish itself

  • Be extra careful when turning your mower – Turning your mower too vigorously can tear out new plants. Where possible try to take longer rounder turns. This is most  important when using a ride on mower.

  •  Don’t mow when the ground is soft and muddy – When the ground is too soft and muddy it can cause ruts and your footprints may well sink in which will ruin your seeded  lawn. New grass plants are fragile and easily damaged. Be careful as they will get buried into the ground in these conditions.

  •  Mulching is preferable to collecting grass clippings – The compost you will create with mulched grass clippings will help to retain much needed moisture for new grass plants  and also provide them with more nutrients.
