The better the foundation of soil you are sowing your seeds in, the better chance you have at successful growth.
Grasses need a firm, but not compacted soil, in which to grow. Good surface drainage is also important, particularly in heavy traffic, sloping or shaded areas.
Munns tip: We recommend that all lawns be planted in a coarse sandy loam mixture of 80% sand and 20% loam, to a depth of 10 – 15cm.
Do you have to prepare the soil differently depending on the type I have?
The short answer to this is yes. If you have a clay soil, you will want to use a rotary hoe to add Gypsum into the top soil at the rate of 1kg per 2 square metres.
Munns tip: It would also be beneficial to add course sand when you are adding the Gypsum.
On the other hand, if you have sandy soil you should again use a rotary hoe but this time add in Bentonite (Munns Weta-Lawn and Garden) to the top 5cm of the soil at the rate of 1kg per 2 square metres.
This will help trap moisture and add beneficial trace elements and body to the sand.
Munns tip: It would also be beneficial to add organic material when you are adding the Bentonite (Munns Weta-Lawn and Garden).
