If they are two different species, and it sounds like they are, they will not breed. You should also know that worms pulled out of your garden soil will probably not do well in a worm bin.

There are three categories of worms: Deep burrowing, soil dwelling horizontal burrowers and surface dwellers. It sounds like you have one each of the first two. Composting worms are in the third category.

Worms must be both the same species and the same size. The size is because of the physical mechanism by which they mate.

Do note that this precludes the existence of so-called "hybrid" worms. There are no such thing, and if there were, they would not be any better than the original worm types.

If you are willing to start from a small quantity of worms, just go to any store that sells fishing worms (nearly all stores that sell fishing gear will sell worms) and ask for "red wigglers". That's the typical composting worm in all but the hottest climates.

we really don't have any fishing stores here. all the fishing stores here are all just sports stores meaning they sell fishing gear along with other sports gear like hunting gear, basketball gear,etc.. so it's hard to actually find a store that sells them not even nurseries here sell them.

but if that is the case i might just go back into the garden and find more worms.

hopefully they are composting worms otherwise i mean im just wasting my time in the end i probably will have to buy worms anyways but they cost like $40 here just for 1/4 a pound which is extreme expensive

Maybe give this a try. Find a leafy area that you have access too. The next food scraps you get, say an apple core, a bananna peel, and three watermellon rinds put them in a shady spot down under the leaves, all in a pile. In 3 6 and 9 days flip them over and look with in the top half inch of soil. If you find some worms. these have a good chance of being compost worms.

i will try that method. but instead i will dig up the earth bury the scraps as their is a lot of fruit flies here i'll have to try around the area i found that 1 big worm i mean it wasn't even deep maybe 2-3 inches into the soil that i tilled
