Broad Beans - Black Leaf Tips

[Pete]

Hi
Was feeling really proud when my first sowing of seeds (Broad Beans) started to sprout in my unheated greenhouse. Planning to plant out in next day or two in prepared bed.
But, the past couple of days the emerging leaves have dry, black (burnt like) tips.
HELP!
Any ideas

Hi Pete, can only think they have got hit by frost.

Hi, I think it was probably frost as well or if you have had any strong sunshine after you have watered the seedlings it could have been scorching from the sun hitting the water droplets on the leaves. They should be O.K. though as I bought some dwarf broad bean seedlings last year from Robinsons & the tips of a couple of the leaves were dry & brown but the plants quickly recovered & grew well.
