onion seeds

HI, bit late I know....but could I get away with sowing some onion seeds and keeping them warm, to plant out as a bit belated autumn planed sets.

Will keep the rest to sow next year.

Cheers

Steve

 

Not even if I keep them on the kichen window sill????

Is it all about daylight hours???

They will grow long an leggy on the widow sill.

Best left like John says, till January at the earliest.

 

If you want to sow onions indoors get some for spring sowing and sow them just after Christmas. You have missed the boat by a long way for autumn sown varieties. You can get some spring sown varieties that mature not much later than the autumn ones.
I tend to sow all my spring sown onions indoors in January or February. I find they take up little room and grow bigger and with fewer bolters than sets. There is also more choice and with the numbers I grow much cheaper even with F1 hybrids.
