Do you know your onions?
Here at Chesters Grove Garden Centre on the outskirts of Chester le Street, we’re seriously thinking about our onion sets. So we thought it might be a good idea to offer a gentle reminder regarding preperation.
Start by planting your onions (15cm) apart or space out (10cm) in rows (20-30cm) apart. Remember, closer spacing will only produce smaller bulbs so there’s no need to space over (15cm) apart unless you are trying to grow giants.
One of the most common problems with onions is bolting. When you see the onion putting up a stong central stalk with a seed head, you need to remove it as soon as you can, use these onions before any of the others.
Remember to add a good fertiliser a week or so before planting out. Fish, blood & bone or even Growmore all work well.
High potash levels will reduce any sulphur uptake, which creates the strong flavour of some onions. Alternativley, try using a low potash fertilizer and although your onions will be smaller, they’ll be more tasty! Yum!
If you’d like more free advice, call into Chesters Grove Garden Centre and ask any member of staff!
Enjoy your Allium cepa
