What's the first thing
you look at when you pick a head of broccoli out of your garden?
Personally, I flip the whole thing over and search for signs of cabbage worms. This year, each head I've harvested has been pristine.
What's the secret?
Starting the plants early so they bulk up before butterfly season is in
full swing. (Yes, the cabbage "moth" is really a butterfly.) I cover
this and other permaculture tactics for dealing with pest invertebrates
without chemicals in The Naturally Bug-Free Garden. Here's hoping your broccoli is just as sweet and caterpillar-free as ours have been this spring.
