Setting-up a wormfarm is a worthwhile project as you get rid of your kitchen and garden vegetable scraps, you have the wormcasting for seedling mix, you can make wormcasting tea, and at the same time you can collect wormcasting liquid.

WormCasting also makes a good brew which is made the same way as compost tea.

Liquid WormCasting and WormCastings contain nitrogen (N), phosphorus (P) and potassium (K) as well as trace elements. The liquid is also ideal to use in hydroponics, tomatoes and cucumber thrive on it.

A good brew for young plants is also 25% brew and 75% water. a weak tea colour. For older plants it is 50/50. This is a strong brew so be careful not to burn the plants.

Before applying liquid fertilizer give your plants a good watering. This will help the plants to absorb the nutrients from the liquid fertilizer and prevent the risk of burning the plants roots and leaves.

Most plants like liquid fertilizer, especially tomatoes, lettuce, the brassicas family, (cabbage etc.) cucurbits (cucumber, pumpkin.)

Plants that like a little liquid fertilizer when they are beginning to produce their crops are peas, beans, and onions when they are starting to bulb, (not before or they will not store well).

Plants that dislike liquid fertilizer, or any other kind of fertilizer are root crops (carrots, potatoes, turnips etc.) if they are fertilised they will be all tops and no bottoms or fork out with very hairy legs.

A good basic rule to remember is that crops above the ground (leaf and fruit crops) like liquid fertilizer, compost and manures, plants that grow below the ground (root crops) dislike much liquid fertilizer, compost and manures.

It’s a good idea to plant a root crop after a leaf or fruit crop.

If you don't have the resources, or you don't have the time, there are organic foliage sprays you can buy off the shelf, but they are expensive.
