Greetings. My name is Bob and I need some advise. The soil in my yard is awful (hard, lots of rocks, dry etc...) so I grow everything in pots. I was given some pole bean seeds and I put then in a 5 gallon bucket with plenty of holes for drainage and they have sprouted but have not grown in over 2 weeks. I thought that rather than having the vines climb up a pole, I'd have them grow down over the edge of my deck that is about 20' off the ground. They simply won't grow any larger. They're not larger than 1/32" tall. Anyone have any ideas. Thanks in advance.
