I use mainly Fish, Blood & Bone which is a slow-release organic fertiliser - it comes in powder or granules and can be mixed with the compost when potting on, or sprinkl.ed on the surface and watered in.
I also use Chicken Manure Pellets for veg which again can be sprinkled on the surface and watered in.
I only use these two or three times a year at the most as they are slow release.
I use liquid tomato food for tomatoes, courgettes and flowering plants. If you don't need to use it all in one go you can get a large plastic bottle or two to store it in a shady place, but please label it clearly with a permanent marker.
