Ok I didn't read any of the responses but my plants fall over each year! I leave them. I actually pray for them to fall over. The plants I let stand I might get 25% less. The greater the surface area the better. The plant starts to fight for light. If you try stand it back up it starts to blow in the wind and will snap because it's weak on one side strong on the other. My advice is just leave it. I can show you pics of mine tomorrow. Plants look like shit but believe me I'd rather a smashed up plant on the ground any day
