Hi folks. I live in zone 3, and I have a question about mulching. In most parts of the country, heavy mulching is the gospel. I've read a few books about cold weather gardening, and many of them suggest foregoing mulch, since the warming rays of the sun don't reach the soil. At this point I don't mulch, except putting fresh compost on each year, and was wondering if there are any cold weather gardeners out there who do use (or have used) mulch, and if so what type and what was your experience? I hate to see the soil becoming so compacted. Thanks!
