.... the new bio dynamic way. Most of the produce crops we grow here are not native to this continent so the predatory insect life has very little history with them. Instead they evolved and developed eating the native weeds that we fight so hard to get rid of. I sometimes have to ask why? I learned a while back that if you leave a few weeds growing in your crop rows that these predatory insects will target that which they're familiar with. The only reason they want to target your cucumbers ( or tomatoes or brassicas etc.) is because you've removed everything BUT cucumbers.
Take a look at this pigweed for example growing in an Armenian cucumber row . The insects have clearly targeted this plant and practically left the Armenian cucumber alone. I jokingly said practically because I had to struggle to find a minute amount of insect damage on this vine. Although it's tough to ascertain because they're behind the leaves, this plant is full of flowers and fruits and has not been hurt by this lone pig weed plant growing here. This is the better looking of the pig weeds and some of them have been completely stripped of their leaves. I never did trust Garden's or Farms's that are completely weed free because I don't think that's the way to go. We are a part of nature and it's about time we start taking a minute out of our" busy" lives ,set the phone down and try to understand our relationship in it. We are intrinsically connected to the world around us. Think about that the next time you feel like you need to get out and weed and are offended by every little purslane, dandelion or pigweed growing around you, every time you remove it you remove food for these predatory insects. Removing most of them is in all of our best interest but leaving a few of them is in the better interest in the long run. I'm wondering if the birds are going to target the seeds and leave my strawberries alone? That's my next observation 😀

Oops, I lost the photo... lost the original post...
Anyway, it's not working for me.
I have SO MANY NATIVE PLANTS to feed the bugs and birds and mammals.
No matter.
They go for my peas, carrots, celery, even my dang broccoli.
