I’m just wondering if it’s possible to make a solution and apply Sulphate of Iron as a moss control to a lawn with a knapsack sprayer? i.e. Will it work the same as applying the dry granuals?The directions say to apply with a spreader at a 30g/Sq metre ratio so just wondering if i can dilute with water instead.
30 g per square metre is a high rate and as little as one-third or even one-quarter of this is the normal rate. On the other hand, this might be already mixed with a carrier. The pure salt is pale green.
