MOVING YOUR WORMS INSIDE
Red composting worms can handle some dramatic temperature changes, especially here in Manitoba. Morning temperatures can hover around zero and soar into the twenties on a sunny afternoon at this time of year. If you’re only vermicomposting outside you may want to consider starting an indoor colony so you don’t have to buy worms in the spring.
If your outdoor vermicomposter is large enough not to freeze solid, your worms will most likely survive the winter. This can be a bit risky however, so it’s always a good idea to protect a little colony over the colder months.
Grab yourself a bin, line it with shredded newspaper if you choose and scoop us some outdoor compost worms and all. Your done, it’s as simple as that, as we’ve discussed before vermicomposting need not be a complicated technical affair.
We always introduce a batch of fresh outdoor compost into the indoor bins in the fall anyway. Like an aquarium, your indoor bin is a balanced mini Eco-system, but like any “closed” system it can get out of balance. Red worms can handle a higher acid ph than most worms but adding material from a successful compost is like giving them vitamins. Just in case they’re missing some nutrients or micro-organisms.
Another preventative measure you can take for your indoor bin at this time of year is to add some dry leaves or grass. This will ensure that the Nitrogen Carbon balance inside remains healthy.
