Garlic in a Zone 5 season
Zone 5 gives about 154 frost-free days. Garlic needs roughly 240 days from sowing. That is longer than the outdoor season here, so this one needs an indoor start, and even then it may want a tunnel or row cover to finish.
How to grow garlic
Plant individual cloves 4-6 weeks before your first fall frost, pointy end up. Mulch for winter and harvest the following summer when lower leaves brown.
