There are thousands of varieties of earthworms, which range in size from 2-14 inches.
Earthworms are an important part of maintaining healthy soil and helping plants to grow healthy and strong. Earthworms burrow in the soil, eating organic matter and creating castings which provide nutrients and minerals vital to plant and soil health. They can eat up to 2-3 times their weight every day and produce lots of great vermicast to make your garden healthy and vibrant.
What to Feed Earthworms
Earthworms love to eat all kinds of organic matter as they burrow in your garden or worm bin and add nutrient rich vermicast to the soil. Earthworms have hearty appetites and like to eat Fruit, Vegetables, Egg Shells, Coffee Grinds (and Filters), Leaves and Garden Waste, Shredded Cardboard and Newspapers.
Red Worms are the ultimate composting worms, because they require minimal care and reproduce quickly. Red worms consume large quantities of organic waste materials and can tolerate a broad range of temperatures. They mainly burrow in the top few inches of soil and release copious amounts of oxygen from their skin so long as their beds are kept moist and food is available. Otherwise, they will escape looking for a more fertile home!
Alabama Jumpers are the most reliable and best all-purpose earthworms around. Their extremely durable skin allows them to burrow through a variety of soils, including dense clay or sandy soil. Overtime, by leaving castings behind as they burrow, Alabama Jumpers will convert the most unproductive earth into a rich, organic soil where plants will thrive. Alabama Jumpers are strong and do not stay at the surface. They are the best natural aeration and burrow deeply, creating air passages in the soil that facilitates root growth and soil health. Alabama Jumpers also have a hearty appetite and will gobble up any compost materials they encounter. They also are productive breeders and should be released in batches.
African Night Crawlers
African Night Crawlers are great for both composting and as bait. They are two times the size of a red worm and can grow to eight inches in size. African Night Crawlers flourish in warmer temperatures and do not tolerate the cold. They have a large appetite and reproduce rapidly. African Night Crawlers are very active and strong and can burrow through dense, clay-like soil conditions. They do very well in raised beds.
European Night Crawlers
European Night Crawlers are a small to medium earthworm. They have a hearty appetite and will eat any kind of compost material and organic matter. European Night Crawlers are approximately twice as big as red worms and reproduce rapidly. They are able to tolerate fluctuations in temperature and environment. However, European Night Crawlers are not fond of extreme heat and will burrow deeper into the soil to when the temperature rises.
