The new beans at over two weeks old are very different. I decided to top the NLxBigBud at the fourth node, and I also removed the branch that was growing out of the cotyledon, it felt like the right thing to do. Conversely the Purple Haze looks pretty healthy and standard but she has had the first node branches removed and I might take more. Because I have decided that the NLxBB is going to take over I'm going to try and just see if I can get the Purple Haze to grow one or maybe two main stems and now much else, otherwise she'll get swamped, I won't be topping her either.
