“Rotline Question” of the Week: Composting Pumpkins?

It is pumpkin season, but now that you don’t need your carefully carved pumpkin any more, don’t throw it away! Pumpkin is a great addition to both your compost and worm bin!

To add pumpkin to either bin, it is important that it is broken down into smaller pieces. Chop, cut, or saw the pumpkin into smaller pieces. If some neighborhood hooligan has already smashed your pumpkin, they saved you some work!


In the compost bin:

Pumpkin is a “green.” It is very high in nitrogen. Make sure to bury the pumpkin or follow the addition of the pumpkin with a layer of browns to detract pests. It is important that the pumpkin is cut into smaller pieces. If a whole pumpkin is put into a compost bin, it will take a lot longer to compost. Also, next time the bin is turned, you’ll inevitably get the whole pumpkin stuck on the pitchfork (and who wants to resurrect a partially decomposed pumpkin on a pitchfork?).

In the worm bin:

Worms will love the variety of pumpkin in their diet. Remember – worms have small mouths so it will take them a long time to work through a giant chunk of pumpkin. Smaller pieces will disappear from the worm bin more quickly. If you want to give the worms a special treat, blend the pumpkin into a slurry, pour it into your bin, and then cover with bedding. The worms will go crazy over this easily eaten treat!
