When I plant my corn, I put 2-3 seeds in each spot, right now some are abt 2 inches tall & others are about 1 – 1  1/2 inches tall. How tall should they be before I start thinning them out to 1 stalk per spot?  Also, I planted bush beans, I did the same thing as far as planting 2-3 seeds per spot, do I need to thin them out to 1 bush per spot or can I leave them all in the same spot? The bush beans are just now coming up, if I need to thin them down to 1 per spot, how tall do they need to be before I thin them out?

Thank you for any help anyone can give me,
