Doesn't look like a bad harvest. I've got some growing in a pot that I planted really late in the season last year. It's just starting to put on new shoots again now as we are coming in to spring. Not really sure if I should dig around and see what I find or leave it to have a whole season growing from now.
So what will you do differently next time?

Well next year I'm going to mulch them and give them I little more water.
