I followed your advice and only used a few seeds each in my 8 planters. I had a wall of borage up to my shoulders. Granted the flowers were pretty and the bees liked them but before they could produce seed I yanked them all and we cut up for the compost pile. It was a load. I don’t want ANY coming up next year. The other flowers were great.
Good! Skip the Borage. The rest of them will still bring in the Good Bugs. :)

The queen of compost herbs is comfrey (Symphytum officinale), which produces many very large, hairy leaves. Its roots travel deep into the soil, and mine the subsoil for key nutrients like potassium, phosphorus, and calcium. Comfrey grows rather quickly which means leaves can be harvested several times per growing season.
