How do you dry your garlic out?
First, do not wash off any freshly dug bulbs. Washing after harvesting encourages rot. To dry them, lay them out on a flat, newspaper-covered surface in a cool, dark, and dry area. You may even want to use a fan over them to circulate the air. They should be dry in about a week, at which time they can be stored until ready for use.
I bought garlic to plant in the fall (instead of my using rather small heads that were grown) but, of course, I got busy and didn't plant it. I live in the lower mainland of British Columbia, Canada. It is quite warm now (no snow, yesterday it was a record high 14% C. ) Can I still plant it now and get good results - I suppose there is no harm in trying it.
Yes, as long as the ground is not frozen yet, you can go ahead and plant it.
I want to know how to plant and care for garlic bulbs.

When do I fertilize my garlic, and what fertilizer do you recommend?
Use a phosphorus rich fertilizer (typically sold as "bloom booster" fertilizer) and fertilize them when you plant them.
Can I use garlic bulbs from the grocery store to plant and grow my own garlic?

I've neglected to harvest my garlic. Now there is quite a large bunch of garlic crowded together. Should I separate or just leave it alone until harvest time?
I was given German red (or purple) garlic plants two years ago. They produced an abundance of seeds from their lovely flower tops. I planted them last year and they grew like onions. I am now separating them and replanting. I have a bushel of them, and I gave away many. So will they form cloves ever, or will they remain like an onion?
They should produce a full bulb in their next year of growth.
