Help with runner bean problem (pest/disease?) - Picks included

[Samuel1988]

Afternoon all,

I was wondering if you could I.D what is up with my young runner beans as they dont seem to look very healthy.

I did spot a few aphids on one but a few couldn't surely be responsible for such signs surely?

Thanks for your help,

Samuel

Looks like a bit of wind burn or sun scorch to me. If I am right they will get over it.

Agree with Potty...they should be fine...If they are in buckets as they appear to be, maybe move them somewhere with a bit more shelter ?

Many thanks.

I have heard of sun scorch but never wind burn.

Is it possible to get sun scorch if the plants are watered say late afternoon?

I think my grandad must have watered them when the sun was pelting down as I do not recall watering them when the sun was beating down on the plants.

Many thanks again,

Samuel

I've tried to give plants scorch by watering them in the sunshine ~ it's impossible.

Your problem is def. wind burn, it happens a lot to tender plants like the S.American beans

Ah I see. How does wind burn damage the plant? Just shows you learn something new everyday!

Have you never come indoors with red cheeks from the wind?

Wind is very dehydrating


The RHS explains it better:

When the wind blows, the rapid air movement causes moisture to be lost from foliage .. if the soil is also dry, plants may not be able to replace moisture lost from leaves fast enough. ..The leaves soon become desiccated and scorched.

They look just like mine, which are behind windbreaks and a large area of new willow. As an eternal optimist I'm trying to grow them in the open in Orkney. Not working I'm afraid As soon as I have a polytunnel I'm going to grow them inside.... when probably it will be too warm for them.

I have seen them grown up in here in sheltered (high walled gardens) allotments - so getting them out of the wind seems to be the best option.
