Hi Plantmark,
I don’t see any supports in place for your Peas?
The second thing is they really shouldn’t need fleece at this time of year as they will take all but the hardest of frosts.
Onions don’t need fleece ever (except Spring Onions). Yellowing leaves usually indicate a nutrient deficiency but in this case I would suggest too high temoerature.
I personally haven’t seen this situation (Onions under fleece) before so I can’t be absolutely certain of my diagnosis. Wait to see what Charles suggests.Don.
What a gigantic effort you have put in there Plantmark! Could the yellowing be residues of horrible weedkillers in the hay/ straw bedding from the horses?
I wished to add an interesting observation from this season; I multi-sowed Santero onion in modules and had good germination. Upon planting, all but one odd module of plants went under fleece for the whole of April – there just wasn’t quite enough fleece for that last clump! The result is the interesting bit; the fleeced onion plants are approximately four times as large as the uncovered clump. Same soil, same amendments – possibly the influence of warmth provided by the fleece?
Hey plantmark,
The project loooooooks really really good. Am impressed! 🙂 Was thinking about the same thing as Stringfellow regarding your peas. Were they growing in well rotted horse manure too?
Yes fleece has helped onions this year.
And they should be greening up now, even without fleece.
Mark your efforts are exemplary yet I am afraid there is some aminopyralid herbicide in that manure, for your peas to be almost dead and the onions not much better.
Its a rotten situation because everybody knows that this particular herbicide has lethal persistence, and any farmer buying it has to sign a statement that he/she won’t sell any treated produce off the farm.
Yet there are more and more stories coming out like this.
Veg families that are affected worst are legumes (e.g. your peas) and solanums, to a lesser extent I think are alliums and lettuce family (endive, asters). However your lettuce look ok, even good, so I can’t be totally sure. Potatoes would suffer, if they emerge with curling leaves that would confirm it, have you planted any?Well those lettuce look pretty fine, except for top right. Check this post I put up last June 2015 where there is a photo demonstrating effects of aminopyralid.
You can see the lettuce looking stunted.
It takes around one growing season for soill organisms to break the aminopyralid down.
But I do not know the answers to most of your questions: you could contact Defra with a photo, and Dow Chemicals who make the herbicide.
However Mark from here its hard to be sure, perhaps there is another cause.
re flowers, I would google aminopyralid.
But as I say, its not a certainty, at least not until you check e.g. runner bean, potato, tomato.This is a helpful pic and hooray, those beans look healthy, no sign of ap imo. `They would not have grown so tall or be so full of healthy flowers & the tops look ok.
That is certainly good news for Plantmark. It would have been a crying shame if all his efforts had been set back by that herbicide. He has done a fantastic job ob his plot – obviously learnt quiet a bit from your course.
But it brings us back to his original question as to why the Peas are wilting and the Onions have yellowish leaves?
Could it be that they were just getting too hot under the fleece?Don.
Oh dear, the spinach looks terribly affected and that is ap damage.
It must vary across your beds because the manure was from different sources.
For the tomato it needs a pic of the growing point. That curl on a leaf margin is nothing severe and could be temperature variations etc.
