Topic: Black tips on broad beans

[caroline7758]

Quite a few of my broad bean seedlings have developed black tips and one or two have gone completely balck. they were in trays in a cold greenhouse. Any ideas why? I was thinking cold, but I thought BB's were hardy?

They are... but are prone to damage on new leaves when hardening off... usually when they have been watered... a bit like scorch I think.

Thanks- do you think they will recover? They are still in the greenhouseand only a couple of inches tall. I'll sow some more as back-up!

One of our plot holders beans are affected in the same way.

My conclusion was scorch caused by watering over head, surplus water resting in curled up leaves in the growing tip then the winter sun shining through the greenhouse glass boiled them for want of a better expression.

The tips were quite crispy!

But they will grow out of it in my opinion providing the growing tip is still intact!

Thanks- probably should have planted them out today with the rest as the sun was shining again!
