We've got some Tomatillos in the polytunnel. Wondering if I need to pinch them out as one does with tomatoes? None of the books

on our shelves mention them. The packet says nothing more than when to plant, temperature etc. The "googlebane"

results are all very non committal. Has anyone got experience with these and knows the answer to the deep and highly philosophical question. Tomatillos-To pinch out or not to pinch out?
