A long time ago, I covered companion planting basics with each of my plants. I’ll go over it again soon, but for now you will have to settle for pictures.
Dill and asparagus:
Basil + asparagus = ladybugs!
I’ve also sewn nasturtium and marigold seeds around the perimeter of the asparagus beds.
Beebalm to bring the pollinators to the blueberries:
Acid loving bay laurel to companion with the acid loving blueberries. It may die over the winter, but only one way to find out if it can survive!
Snow peas to climb the accidental corn:
And finally, clover with just about everything else that is a heavy nitrogen feeder (hops, asparagus, blueberries, as a living mulch in fallow beds)
