Crab Shell should be worked in the soil before planting, or top dressed. It can be applied to lawns with a broadcast spreader. It shows amazing results on lawns and all plants.
Apply in early spring as soon as soil can be worked. For perennial crops, apply at the end of dormancy. Mix thoroughly with the soil or growing media, taking care not to apply in concentrated form directly to the roots. For trees and turf, apply directly as a top dressing.
