About Brussels Sprouts

Brussels sprouts have a long season but reward patience — sprouts actually improve after a light frost.

Start indoors 8 weeks before last frost. Plant in the sunniest spot. Needs a long season — start early. Frost improves flavour. Stake in exposed positions against autumn winds.
