Fertilising Your Lawn

FertilisingInitial Maintenance Your new lawn has no roots system established yet, so fertilising program will be different for the first 12 months. It will always depend on your soil type and how much fresh & improved soil you have added to your site as to the frequency of the application of fertiliser.

Hopefully you have fertilised when the lawn was laid, this will be adequate for the first month or so, often you see a change in colour which tells you it is time to feed the lawn.

4 – 6 week period apply ‘Sir Walter’ Fertiliser @ 25 grams to the square metre (2.5Kg per 100 m2)
10-12 week period apply ‘Sir Walter’ Fertiliser @ 25 grams to the square metre (2.5Kg per 100 m2)

Continue this on a regular basis for the first 12 months, that is each time the colour starts to change, 8 – 12 weeks apart.

Regular Maintenance
Regular applications of fertiliser are essential for strong, healthy and deep rooted lawns. A mixture of organic and artificial fertiliser is recommended to promote steady growth, and the best times to do that are Autumn and Spring. Depending upon your soil, it may be necessary to fertilise more in the first couple of years until the roots of the turf have fully established.

TIP: Fertilise when first laying turf. Use a starter fertiliser such as Sir Launcher.

You can continue using ‘Sir Walter’ Fertiliser constantly if you like as it is a complete fertiliser, however lawns are generally not fussy and anything with the N:P:K in the area of 15: 2 : 10 is okay.
