To get you started you need the following:-
Soil amendment (2KG per square meter) to mix into the top layer of your existing soil.
A 10 cm layer of our specialised soil grow mix to overlay on your existing soil (Or the soil in your above ground garden bed or your potted plants). The cost per square meter of both combined is $80 Plus GST.
Feed for your weekly feeding routine. This is necessary because you are growing vegetables intensively and they extract nutrients from the soil. The feeds you need are detailed below. Most components in the feed will last you at least a year.
