I have noticed yellowy patches on many of the leaves of my brassiccas
This seems to have especially affected the Greyhound cabbages and m
Swede. Having googled the problem i think it might be the 'Meal
I am quite dissapointed as spent quite a lot of money on Enviromesh i
an attempt to stop this sort of thing from happening but these thing
are sent to try us!
Has anyone experienced this before and if so do you know of an
remedies that might prevent me from losing everything as i am new t
growing any veg!
I'm in the exact same position as you. I'm a new vegetable grower and
only got my allotment last March.
But, because there was no fencing around my plot, I bought Enviromesh to
cover my brassicas to prevent attack from rabbits , birds and
butterflies. And in that respect I am very well pleased. The product
does work and my brassicas look terrific with little damage compared
with those of my neighbours.
And yet , I have also noticed, in recent weeks, some yellowing of some
of the leaves, especially the sprouts. However, I don't know what the
cause of this is or how detrimental this is to the plants.
Have you looked on the underside of the leaves of your plants. Do you
see the aphids?
I will certainly take a look myself tomorrow and see if I can spot
anything and let you know.
Maybe just a squirt of derris (or whatever insecticide you like) is all
that is necessary.
I am pretty sure they are the Mealy Cabbage Aphid. I first noticed the
on the sprouts but squashed them all! They seem to nest in folded part
of the outer leaves. I have now noticed them on the Calabrese, Swed
(ravaged) and Greyhound Cabbage.
I have pulled 2 cabbage out completely as they were badly affected an
i was worried that they might spread to the other plants and they woul
never have been very edible
The aphids seem to suck all the colour out of the leaf turning i
yellow and dry
I am trying to be as organic as possible and i don't use insecticide
unless it's a last resort.......this might be one of those occasions
You said you were using Enviromesh? Perhaps the aphids got in whilst
you were planting out or when you removed the mesh to do some weeding?
Now, regarding Enviromesh, tell me this... Is there enough slack in
your mesh cover to allow the calabrese and sprouts to grow to full
height? In my case, there is not, so I will have to construct some kind
of low cage with netting to keep the butterflies and birds off the
crops. But that will let the aphids in, I guess. What about your situation?
My sprouts are not under the mesh and they seem to be doing fin
without it (i have had to stake them to protect them from the wind). M
Calabrese, cabbages & Cauliflower are covered with Enviromesh and
think they will remain like that until they are ready to harvest
I think i will just stake around the bigger plants i.e. sprouts an
purple sprouting broc, and put some mesh or chicken wire over to sto
That's the plan anway
I am getting a bit confused with all the different types of cabbages
cauliflowers & calabrese i have planted and when they will be ready t
harvest......i think i will just keep going and if it looks ready
will eat it
