My onions were awful last year - many just rotted in ground & others succumbed when stored.

So what I would like to know is...

Does anyone have experience of planting onion sets in a poly tunnel in March?

Will I get a successful crop?

Help!!

I will be interested in the replies to this post....

I planted my onions/shallots out last Sunday and found I had six left...I didn't want to have half a row, so I have planted them in my greenhouse border
I am in my own little world, ...it's OK, ...they know me there!

Slightly off topic, but might be helpful.

I stopped growing onions a few years because of almost total losses from sooty mould. I started growing my shallots (also usually badly affected) in the polytunnel, and have always had an excellent crop. Fortunately they can be planted very close and don't take up to much room - also they are out of the bed in June and there's plenty of time for a following crop.

Timetable is this:

1 Plant in seed trays mid to late January

2 Plant out mid February when green tops and roots are well developed

3 During April and May thin out and eat as spring onions*

4 June lift crop and hang up to dry

Steps 1 and 2 could, of course, be combined by planting directly, but I never seem to have the bed available/prepared until February.

I don't see why this would not work with onions.

* we have neighbours who are mad for the first slotch (our local pronunciation of shallots!), cooked with potatoes in buttermilk.

Thanks Alan & Weed

As you will see not many replies so I shall have to try with sets now & see what happens.

Many years ago I was fortunate enough to see Bernard Salt's Keder House - he had smashing onions growing in there - about May I think it was. They were sets he had planted in the autumn. Unfortunately his book Gardening under Plastic does not mention onions.

Hi LG I plant onions and garlic in my pollytunnel every year, usually winter onions and garlic at the same time in the Autumn but I am up in NE scotland and global warming has'nt reached us yet.I do get good crops and my local village veg shop pays me 50P each for the garlic. I also have 8 Asparagus plants as well and they are prolific.If I had the money I would cover my whole garden in pollytunnel.
So I would say go for it plant some inside and some out and see what happens.
