Seaweed is NOT Food!

Seaweed improves the performance of fertiliser and is not a substitute. As a guide we would say to apply granular or liquid fertiliser a week to a month after any application of seaweed. If you are maintaining a regular supply of seaweed into the lawn this becomes less important though you should always look to apply fertiliser at least a few days after any seaweed application.
