Note: whilst this step is optional and some of the products can be difficult to come by, if you want the absolute best lawn possible we recommend you follow each of the four parts below.
Part A: Add some PowerFeed to the soil.
For the Powerfeed, add one capful (10mL) to every 1L of water in a watering can and spread across the soil area.
PowerFeed contains a variety of different ingredients including fish, liquid compost and macro nutrients. It is basically a soil conditioner and liquid fertiliser combined. It is made by the same Australian company (Seasol International Pty Ltd) who make Seasol which is another excellent product. One of the other benefits of PowerFeed is that it works to break down clay soils and reduces nutrient loss in sandy soils.
Part B: Add some Bactivate.
Bactivate is available in 25kg bags. It is “a microbial soil conditioner composed of 5 specific bacillus species that enhance plant growth and protection.” Apply as per packet instructions.
Part C: Add some Bentonite Clay
Bentonite is a natural clay with no added chemicals. It will save you time and money in the long term due to its water and fertiliser efficiency. When used in conjunction with compost, it will aid soil wetability, increase water holding capacity and improve soil structure.
To apply Bentonite, spread its clay granules over the soil surface at a rate of 0.5 – 2kg per 1m2.
Part D: Add some Zeolite.
Zeolite is known to produce significant grass root improvement. It allows your turf to have a dense feeder root system and similar to Bentonite, it allows for less fertiliser to be used.
Zeolite is available in 15kg bags with 1kg needed per square meter.
