Anyone grown Edemane beans?

I tried these for the first time this year, but even in the polytunnel they didn’t do very well - just a handful of beans off half a dozen plants. Too cold here in the north east of the UK perhaps?

I was wondering if anyone has grown these successfully?

Ever the optimist I have another go at soya, both indoors and out, every couple of years. And like you I just get a handful of pods. As far as I can tell it is more a day length than a temperature problem. Edamame is a Japanese crop and although a great deal of soya is grown in Hokkaido, where weather is not that different from NE England, it is still a good bit further south so day lengths are different. There are now varieties that yield quite well right across southern England, ten degrees north of Hokkaido, but they are all being bred for commercial field scale bean production and are only available to large scale commercial growers under very strict licensing conditions. (We are in “grow this without a license and we sue” territory here. Like GM crops.) They also like pretty light soil - are you growing them in raised beds or on the flat in the polytunnel? They do a little better for me on raised beds. My raised beds, indoors and out, are currently standing in six inches of water. Meant to pick the last of the tomatoes today but there’s a hole in my wellies below water level.

You are a font of knowledge Catherine! I hadn’t thought to check on day length needs which is rather remiss of me. This is the sort of info that seed companies really need to get better at putting on their seed packs!

In answer to your question, mine were growing in raised beds, admittedly on clay soil. The plants never looked that happy, like there might have been nutrient deficiency. It might also be that I planted them a little early - and before much nitrogen was available in the soil them.

I grew soya beans here in North Yorkshire one year when there was a lot of sunshine, but under no special conditions. They grew very well in the front garden and produced lots of pods. Not wanting them to eat as green edamame beans I just let them go on to mature and form seed, which they did very well. One day I found the hens plus cockerel in amongst them and exhibiting a peculiar activity. They just ran en masse to different parts of the plot. When I went outside, I could hear the bean pods popping open, and saw them all rush to the sound of the popping and consume the beans as they flew out. A warning perhaps for anyone wanting to save seed and keep chickens! Never grown them since, but in my opinion, warmth made them successful.

Can you remember which variety it was Sheila?
