DE is the only way I can grow collards and kale without them being et up alive by the tiny bugs that love them.
Aphids? They’re totally evil. Satan’s little pets. They’ve killed countless numbers of my previously healthy and productive bush-type green bean plants. Yep, a good dose of DE will fix their little wagons. :-)
Another thing I like about it is, it’s (pardon the pun) dirt cheap.
