Thanks for keeping these coming. It sounds like you could profit from splitting your plot into experiments, including baseline for control.

How is your soil pH doing? Have you considered paying for soil analytics once to check for potential problems?

I’ll be adding some wild type sunchokes to my grass roof this autumn. The last time I used commercial cultivars which became a pest but never flowered.

Most of the new plants I add are eaten alive by snails and bugs. Jerusalem artichokes seem to thrive and bear fruit, which is rare.
