How To Care For new lawns

Watering, mowing and fertilising practices are important for a newly laid lawn

A newly laid lawn should not be allowed to dry out over the first couple of weeks. Once established, your should first mow your turf when it has grown to 6cm high remembering never to mow more than 1/3 of the leaf. We also recommend using a fertiliser to keep your lawn green and healthy.

Short term care for new lawns


For the first 7-14 days, or until the turf has taken root, you must keep the soil moist. This will ensure your new lawn can establish a good root system and will help it last through hot and dry weather.

After your lawn has taken root you shouldn’t be able to pull corners of the turf up, water carefully for the next 3 weeks.


New turf must be firmly rooted before you can start mowing. The first mow happens when the lawn reaches about 6cm in height, do not let it grow higher than this before the first mowing.

Subsequent mowings, while they turf is still establishing, should not be done below 4cm.

Remember to never mow more than 1/3 of the leaf.


We recommend you fertilise your lawn six weeks after laying, followed by a deep watering. This will help give the new turf the nutrients it needs to grow into a strong and healthy lawn.

Long term care for established lawns


Once established, your lawn only needs watering when necessary. This is usually one deep watering a week, about 25mm is sufficient, and will help to produce a more drought tolerant lawn. Remember, sandy soils may need a little more watering.


Weekly mowing is recommended during the summer months as this when your lawn will grow quickest. As the growth pattern slow, less mowing is required. Always remember not to mow more than 1/3 of the leaf.


Though an established lawn doesn’t require it as often, we recommend spreading a fertiliser across the turf during the spring, summer and autumn months.

Frequently Asked Questions / More Detail

Do different turf varieties need mowing at different heights

Our recommended mowing heights are as follows:

  • Sir Walter 35mm – 40mm
  • Eureka Kikuyu 20mm – 25mm
How do I know when I've watered my lawn enough?

By placing a container on the lawn when watering, you can take note of the time it takes to collect around 25mm in the container. This will give you a good idea of how long it takes to water your new lawn.

How often should I fertilise an established lawn?

If you’re using a granular fertiliser, we recommend you fertilise your lawn in spring, summer and autumn.

For an organic (liquid) fertiliser, we recommend a monthly application during spring, summer and autumn.
