How To Apply

Watering can: mix the amount suggested (typically 10‐30ml)/9 litres of water.

Hoseon Bottle (Seasol/weed n feed etc.) or hortex sprayer: mix the minimum amount of water with the product/s to allow you to cover the required area/s. For example, for my front yard, using an old weed n feed hose‐on bottle I add 100ml of each Seaweed Secrets, Activ8mate or Activ8EXTRA and Natures Soil Wetter, then top up with enough water to allow you to evenly cover it using the hose‐on bottle (I add about 600ml water), then evenly hose‐on. If using a Hortex sprayer on setting 2 without the restrictor, you shouldn’t need to add water, but if you do, just add as little amount to cover the required area.

Pressure/knapsack sprayer: You need about 15 litres (a little more or less won’t hurt) of water to be applied per 100m2, so take that into consideration when applying. If you have a smaller sprayer, either do several smaller applications i.e. covering 50m at a time and repeat until the entire area is covered, or over a larger area spray with the required amount and if you haven’t used 15 litres/100m2, give a light water‐in
