What it is

A potting mix built from a peat and pumice base with worm castings and compost, then amended with lime, gypsum, mussel meal, karanja and neem seed meals, Acadian kelp, basalt rock dust and potash. Made in Seacliff, Otago.

• Base: sphagnum peat moss, pumice, worm castings, compost
• Amendments: ag lime, gypsum, mussel meal, karanja seed meal, neem seed meal, Acadian kelp, basalt rock dust, potash

What it does

• Feeds slowly. With a working soil food web the amendments break down over time and release their nutrients to the plant through the crop.
• Suits high fertility single use growing straight from the bag, or forms the base of a super soil, living soil or no-till recycled soil with further amendments.
• Karanja and neem seed meals are in the mix; growers use them to deter soil pests.

How to use

• Houseplants and vegetables: pot up straight from the bag.
• Living soil or super soil base: use as the base and add further amendments to suit the crop, or move up to Living Soil v2, which is fully amended.
• Salt based feeding: can be used as the medium under a mineral nutrient program.
• Watering is where most problems start, both too much and too little, and letting the mix dry back is the usual cause. Keep it evenly moist rather than aiming for runoff: water in small rounds, check the edges for dry pockets, and use a moisture meter.
