We have provided some general instructions for how much to use on our packaging. As further guidance, a good general rule of thumb to follow would be about 1 litre of solid Arktivate for 1 square metre of planted area. If you are planting in pots, an easy indication would be a loose handful for a pot 4 inches (10cm) in diameter; you can scale up or down accordingly based on the size of your pot. For liquid Arktivate, we recommend a fortnightly application of 1:50 dilution for seedlings, young plants and smaller plants, and a 1:20 dilution for older and more mature plants, including shrubs and small trees – using the same amount of water as you would when usually watering.
