Onions - Autumn planting
Any one else having a go this year?
First time trying onions, ive ordered a bag of mixed sets to try.
Ive got a couple of questions
As my garden is all concrete i bought a large reusable grow-bag, (H23cm x L100cm x D40cm) i believe this should be suitable for about 2 rows of 10. Figured it'd be better than pots.
Ive bought bulb compost to fill the grow bag and blood/fish/bone to scatter in as i fill the bag. Then some netting to go over the top to stop the birds getting to them.
Is there anything else i need to do?
How big do onions from sets get come June/July?
