Don't hybernate from your garden just because there's snow outside.
Here are some things you can do to get ready for the coming growing season.
Read catalogs and dream. Order seeds early, taking care not to order if you still have viable seeds from last year.
Check stored vegetables frequently, removing those that have rot or other spoilage indicators.
If you haven't already, cover compost pile with tarp to prevent rain and snow from leaching nutrients out of the pile.
