Due to wild life pressure and the need to preserve seeds, I grow some edamame/soybean in pots this season. They are large pots, like 15 to 20 gallon plastic ones.
Here is a photo of FledderJohn. The large plant is about 18" tall. The catalog says it can grow to 24" to 36".
I do not know if this variety is determinate or not. At this rate, the plants can reach the mature height rather quickly. I assume I’ll need to support the plants at that high and they are in pots.
