Worms allow your compost to breakdown much quicker and you will be rewarded with great organic soil improver. You can simply put your scraps in your compost heap. However, too much citrus or onions cause soil to become acidic, and meat and fish will attract flies. As the compost breaks down, ensure it does not become too hot for the worms. Don't forget to water your compost.
Worms love to be moist.
If you don't have a compost heap you can use a box. The large plastics firm, Reln, has been re-cycling plastic and come up with an environmentally friendly product called a 'worm factory'. The factory consists of 4 plastic trays. Your kitchen scraps go into the tray above the bedding to feed the worms, and the worms turn you unwanted garbage into great castings for your pot plants or garden. Each time you water it filters through the castings to the collector tray and makes liquid fertilizer for pot plants or gardens.
