Do I water in Plant Doctor products?

Some Plant Doctor products require watering in while others are left to be absorbed through the leaf of the plant. The application process (pressure sprayer, hose on bottle, watering can etc) will also influence the requirement to water in or not. It is always best to read the label prior to applying to ensure it is applied correctly which in turn will produce the best result. Activ8mate when applied with a pressure sprayer needs to be watered in lightly.

Should I mow before or after liquid fertiliser?

Ideally liquid fertiliser is applied after the lawn has been mowed, do not mow the lawn shortly after applying liquid fertiliser particularly if it is applied foliar as the effectiveness will be reduced.
