Notice the lowly earthworm, squirming away, going about its everyday business. Simple creatures you may think but they have quite a important use in the garden. Did you know the earthworms are nature’s first gardeners? They don’t exist just for kids to eat and fishermen to use as bait 🙂
Some Basic Earthworm Facts
Earthworms are present in almost every type of soil but the healthier the soil the greater the numbers. A healthy soil permits lots of air and moisture, both of which are needed by the earthworm for a continued existence. Earthworms have no lungs like you or me but instead breathe through their skin. Their whole skin absorbs oxygen and releases carbon dioxide. They also need moisture to assist them in respiration but too much moisture is not good for them.
There are four types of earthworm that you may run into:
Nightcrawlers: 8 to 10 inches long and the fisherman’s favourite.
Garden Worms: 5 to 7 inches long and found commonly in damp soils.
Manure Worms: 4 to 5 inches long and found in manure rich soils.
Red Worms: 3 to 4 inches long and the most commercially available.
