Griffin Posted July 9, 2011 Share Posted July 9, 2011 I've never grown onions before and earlier on this year I planted out red onions. Some of them are in flower now. When do I harvest them? Quote Link to comment Share on other sites More sharing options...
sjp Posted July 9, 2011 Share Posted July 9, 2011 the ones in flower have bolted and need the flower heads removeing if any of those are a useable size then pick them bolted onions don't store so will need using first any that arn't of a useable size go in the compost. the none flowering ones you leave until the green dies back and turns a strawy brown colour then lift them and put them somewere to dry potting shed bench or on an upturned crate the blue mushroom flats are ideal in a cold frame with the lid open at max to allow for airflow but set to keep the rain off to finnish drying. spring planted onoins should be ready to harvest about mid to late August red onion sets are prone to bolting you can lose about 50% of the crop to bolting. seed grown red onions don't tend to bolt Quote Link to comment Share on other sites More sharing options...

counturchickens Posted July 10, 2011 Share Posted July 10, 2011 Griffin, don't worry. Our onions have been a nightmare this year, I think it was just too dry in the spring. Quote Link to comment Share on other sites More sharing options...
Ain't Nobody Here Posted July 10, 2011 Share Posted July 10, 2011 Glad you asked the question, I didn't know all that either . Will be checking my onions tomorrow . Quote Link to comment Share on other sites More sharing options...
Griffin Posted July 10, 2011 Author Share Posted July 10, 2011 I harvested the most pathetic crop of red onions known to man Glad to have a bit of extra room in the garden now though, I was able to move Tiger and her new chicks to a bigger run Quote Link to comment Share on other sites More sharing options...
Lesley Posted July 11, 2011 Share Posted July 11, 2011 I had to harvest onions and garlic early as well once I'd noticed some garlic with white mould - I lost about a third of my crop to it a couple of years ago. Quite a few of my onions had started to produce a flower and had thick middles. They've dried reasonable well and we're using the odd ones first.

Yes, if you notice them start you can cut the flower head off but once they've really grown then you need to harvest those. The hot dry Spring made it worse this year.

chickencam Posted July 11, 2011 Share Posted July 11, 2011 Red onions are the most prone to bolting in light soils and dry weather, we only ever get a few each year. Onions are ready to harvest when their tops fall over and start to turn brown, we lift ours and put them to dry somewhere sunny and hot, not always easy, we lost a lot last year because they didn't dry properly in the damp autumn and lost lots more to the frost in storage. We are normally totolly self sufficient in onions, but not last year. This year's crop will be small onions but we planted an awful lot so should be ok hopefully.

I've got one bed that's got it in.plus we've got allium leaf miner on the allotment and I've just found out how my onions at home are getting flated my cream legbar grower can get through the electric netting as it's not electrified Quote Link to comment Share on other sites More sharing options...
