Additive Humiclay 25L Bag


Humiclay has all the benefits of Turf Perfect, with the addition of bentonite clay to help transform sands into more functional soils. Clay can help you overcome water repellency and protect your soil’s valuable organic matter from being lost. It can also support compost in storing more water and nutrients in the soil, and building soil biology. For new garden beds apply 10mm to the surface and turn in to no more than 100mm. For phosphorus sensitive natives, apply no more than 1mm thickness for any situation, or mix 1-2 cups into the planting hole of a new shrub.
