The people who sold us our worm farm gave us this advice for giving the worms a special treat: put some melon in their bin. Red wiggler worms love melon, they assured us, and will mob any pieces you give them. On the way home from church yesterday, we bought a watermelon from a local farmer. It was red, sweet, dripping, and delicious...and I couldn't wait to share the remains with the worms.
When I last checked, they hadn't shown any interest, possibly because I froze the melon pieces first, so they would also provide some Worm A/C. I'll check again tomorrow. However, I can report that they are going absolutely bananas for their Carnegie Mellon moisture mat.
On the left is what it looked like when I first put it in the bin, not quite two months ago. On the right, what it looks like now. If you click on the picture and enlarge it, you'll see a few worms (red-brown), some melon (green and pink), a lot of castings (brown), and the shredded-paper bedding showing through a large hole that they have eaten through the middle. (The green is another piece of cloth on which I place the frozen water bottle for cooling; I've pulled it aside so you can see the hole.) What you can't see is the masses of worms swarming under and through the mat; "infesting" would be a good word.It's true: Worms love melons. But they can't spell.
