To me companion panting includes a whole succession of diverse plants working together to achieve abundance.
It spirals out from this garden bed to our whole farm and plants grown for other gardeners (birds, insects, worms, fungi...) what we want to eat, and then scaled down through the farm to the whole garden rotation, annual and perennial crops, seasons, microclimates, seeds to save, earth covered for as long as possible.....A crazy dance.
Photo number 1 is of a mixed greens bed planted into the mulch of winter cover crop (Lettuce, radish, red onions, rocket, cornflower, sorrel, sweet pea, ) Last summer this was a kumara bed that was replaced with a diverse cover crop. The path is mulched with bark from the bottom of our woodshed as this path will be walked often when collecting salad.
Photo number 2 shows the rocket flowering and magenta spreen coming up. We have just planted some Hyasinth been vine down the middle to add beautiful flowers to our summer salad and shade to the salad greens. Because I will be saving the lettuce seed I will be leaving the lettuce in for a while. Next summer this bed will be a grain crop.
