Everyone loves the greenhouse! The warmth, the wind break…crops, weeds, all plants love it in here. Now it seems flea beetles have acquired the taste as well. For whatever reason, the FBs usually stayed out of the (much smaller) little greenhouse, but here in the new big house—munch, munch, munch—bok choi is under attack. Hoped for a free pass on FBs in here as well, instead, it’s row cover. Learning as we go…
Watch the plants carefully. Row cover can trap flea beetles in. They’re soil dwellers.
Yep, for row cover to be effective against flea beetles, you have to apply it immediately, right when you transplant, and before direct seeded crops emerge…row cover everywhere! I’ve seen ’em attack the tiniest, just-emerged seed leaves of brassicas. We put it on right after seeding for salad greens, and water in through it. The FBs seem to have come and gone on this little test planting of bok choi – they do that sometimes in spring – and they haven’t hit other brassicas in the greenhouse, but I’ll cover future spring and summer seedings in there, just to be safe.
