Went out to check sproutage today...
Beets're lookin' good.
Even the old mustard seeds I didn't think would sprout did.
But what's this?!
Oh, you little BASTARDS! You got them ALL!!!
FINE. I'mma' gonna' get ALL o' YOU!!!!!
Bt. Bacillus thuringensis. Kills them ALL!
BOTH the cabbage looper and cross-striped cabbageworm.
Some tips for using Bt:
- Use fresh Bt. If your bottle is four years old, it's dead. Bt is alive, a bacteria that's dormant, and it dies over time or if left in prolonged heat. Speaking of that:
- Store it at room temp. If you left your bottle of Bt in the garage through last summer, it may be dead. Buy another one and this time store it under the kitchen sink.
- Mix a fresh batch each time. When you mix it with water, it "wakes it up" and it dies in about a day and a half. The worm has to eat it when it's alive, so spray in the evening if you can.
- Coat the entire plant. Pay close attention to the undersides of leaves. A lot of the time moths will lay their eggs under leaves to protect them from rain. When they hatch, the worms are so small they don't really move far, so if you don't spray under the leaves where they are, they'll likely survive and you'll have to deal with them later, when they're bigger and can eat more.
- Tip for coating underneath leaves: Starting at the bottom of the plant, use a broom or leaf rake to "rake" the leaves upwards and follow it closely with the spray before the leaves fall back down.
- One more tip: Some gardeners spray their entire garden once a week with Bt as a preventative. I don't (obviously), but I may start. Neem oil would be another good thing to use regularly since it would nip beetles in the bud when they're still tiny.
Now go get those little bastards. I did and feel much better for it.
