If you are using the osmocote beads, they should last three months. I use blood fish and bone, the blood is pretty instant, the fishmeal breaks down in a couple of months and the bonemeal a bit longer. Generally I use one dose at the start of the season. For certain pot grown stuff, I add a soluble feed after a couple of months , tomatoes particularly run out of steam if not fed regularly.
