Q.Proper supports for pole beans
I have planted beans in large pits this year, using 3m high dowels as supports. One of the plants has already reached the top of the support. Will it keep growing? And what should I use now for supports?
Got a little over-achiever going there, don't you? You can just let the top dangle -- when it finds it has nothing else to climb, it should turn it's interest to making beans. Or you might try getting some even longer poles and setting them up as teepees, to support the monster. Here's an article that might give you some ideas: https://www.gardeningknowhow.com/edible/vegetables/beans/pole-bean-supports.htm
