Onions from seed?
« on: April 27, 2024, 08:11 »
Has anyone on here grown their onions from seed this year?
Iím really interested in this as I like to experiment.
Iíve got a couple of trays that were started in January, but they still look nowhere near ready to go out into the big wide world, but Iíve nothing to compare with.

Would love to hear some experiences and advice please!  :)

we started like you in January in propagators now planted out and doing ok i would guess about 8-10 inches high mostly in rows about 4 inch apart 6 inch between rows some [red baron] are in groups of about 6 dotted around other plants  our main white onion is Ailsa Craig which normally gives us large onions that store well we are just using the last now. good luck.
from bow like to grow

I have never managed to grow on seed onions and leeks to the size recommended for planting out, but as soon as the weather is looking ok mine go out in the garden anyway.  I planted the onions and leeks out last week, although the onions weren't huge and the leeks no better than bits of grass, never mind the recommended thickness of a pencil.  Both have grown on quickly in only a week, so it's worth having a go.

Thanks both for your replies. Iíve prepped a couple of beds ready for them and hope to get them out one day next week.

steven c - thatís really helpful re the spacings. Thatís a good idea to dot any spares around.

jaydig - Iím glad you said that as I always lol when it says ďplant out when thickness of a pencilĒ , mine are barely the thickness of the lead inside a pencil!  :lol:

I will definitely persevere then, thanks for the encouragement!

Forgot to mention that onions and leeks do better with a bit of lime raked into the soil, and generous doses of manure or fertiliser when they get going later in the season.  Managed to get seed for the old Kelsae last year, and got huge, very mild onions just like the Spanish onions we used to be able to get years ago.  As a friend's husband used to say, Ya could ate em like an opple!! Translation: You could eat them like an apple. :D

Try it and report back, you might just get small onions . You can still plant sets ASAP though and get decent sized onions


I always start seeds end of february, also west of Scotland. Grow on in greenhouse and planted out early April. I've had to put some sets in to replace some that got eaten though.


As for leeks I put them out after the potatoes, typically in June. I'll have potted them on by then and they should be as thick as a pencil, touch wood

When is the best time to add the lime jaydig?
I was planning to plant the seedlings out, maybe on Monday so could pick up some lime tomorrow, but would that be harmful to plant out so soon after liming?
Sorry for all the questions!

I have grown mine from seed for the last 8 years or more.
I find the quality is far better than a set.

Start mine by chitting the seed in damp paper then sow in 12cm root trainer's before planting out.
Mine are due for final planting in the next couple of weeks.

Cavolo Hero -      I usually add just a sprinkle of lime and rake it in well about a week before planting out. The feed/chicken pellets/6X or whatever you choose can be added when they start to look more like little onions/leeks than bits of grass. Keep them watered well and hopefully you should get a decent crop.

I always grow from seed. It doesn't seem financially logical to grow from sets but so far dire. Hardly any seeds have come up. Growing in trays in greenhouse/conservatory.
Might be the seeds are passed it though. I do have some doing very well which I planted in the autumn. I must admit they are rarely large but on the other hand it's dirt cheap to grow from seed. Specially as I buy from premier seeds! Twice the amount for half the price!

I started trying to grow from seed last year because, frankly, sets just seemed like a waste. I'd plant maybe 10 and there'd be all the rest of this massive bag... I'm not trying to grow too many as the wife isn't overly keen but seriously, who's growing that many onions??

Anyway, biggest tip I've learned so far is to trim the seedlings to about 2 inches off the soil so that they don't collapse and die off. This year I'm going to try planting in Sep and overwintering seedlings to get a really good start next year. Well that's the theory.

Thanks for the tip. Iíll bear it in mind when I start the process later on this year.
How are your current ones getting on?
What varieties have you gone for?
Mine have done surprisingly well, and Iím definitely going to try from seeds again  :)
