Pardon if this has been asked before but I'm a newbie (both to vegetable
gardening and this newsgroup). I planted brussel sprouts for the first time
in my Massachusetts garden this year. The seedlings I started inside didn't
transplant well nor did many of the seeds I sowed directly take hold in the
garden. I only have about three plants growing. And now the leaves are
covered with holes and I'm finding inch-long smooth green worms on them.
They don't seem to be on any of my other vegetables or herbs. I try not to
use any pesticides on my small garden but I'd like to have my kids see at
least one impressive brussel sprout stalk grow to maturity...any suggestions
for non-chemical/pesticide deterrents for these pests?
Also advice on getting brussel sprouts to grow in the first place

Thanks
