Hi there,

I have a couple of rows of garden peas planted and over the last couple of
weeks a white powdery substance has appeared on them and it would seem that
the plants are suffering as a result, although the mature peas seem to be
uninfected.

Any suggestions please as to the cause of the powder.

many thanks

Mildew? Often occurs in dry weather. Make sure the peas are kept well
watered. If you already do that, then I'm out of suggestions!


By "well watered" Chris means a watering can (1.5 gals) for every, say, 5ft
of the row. You may already be doing that but I see some allotment holders
using only enough water to change the colour of the earth not water the
plants and then wondering why they don't look like mine.

Thanks for the reply Chris. Yes they were watered aplenty, but the ground
doesn't hold water that well so your suggestion could well be the problem.

Thanks for the reply Bob. They were watered with using a hose pipe and a
copper pipe adaptation that I made up with a watering can hose on the end
(fairly severe erosion of the bottom couple of vertebrae of the spine make
one more inventive to save bending and carrying) and they were very well
watered, but as I replied to Chris, the ground doesn't hold water well (too
free-draining) so that could well be the problem.

In my experience, peas do not do well in my soil, which is light
like yours. I now grow only snap peas, and get a decent crop
only every few years. I am not prepared to water heavily every
day.

You could try doing what one of my old mentors used to do with his runner
beans. He dug a trench where he intended to plant his beans and lined it
with damp newspaper and filled with compost, not even well rotted, covered
with soil and planted into that. The compost and newspaper held moisture for
the plants.
The problem this year is that it is so hot you may have a problem no matter
how much you water, peas just don't do heat IME. Perhaps give up on maincrop
peas, as we have, and go for "Early Onward" so they are cropped and in the
freezer by now.
