Bolting Onions!!!!!!!!!!!!!!
« on: October 13, 2007, 06:43 »
Hi,
I am browsing through my seed catalogue and provisionally deciding my seeds for next year.

In the Onion set section they have a some Heat treated sets, which the brochure says reduces 'bolting'. I have heard this term 'bolting' quite a lot and have read the glossary of terms in which it says that when bolted a plant is producing seed.
What causes bolting particularly in Onions and what percentage do none[/u] heat treated Onion sets bolt? Is it worth buying the heat treated sets? Is bolting a problem enough in Onions to warrant the extra payment for Heat treated sets.

Also what are the negatives to buying heat treated sets other than the extra cost? Do they produce a better or worse crop, do they taste any different?

Taste is the most important thing to me, its one of the main reasons why I have got my Plot.
99% Organic and 1% Slug Pellets.

Good morning, Fb,

Unfortunately, it can depend on variety, I know Red  Baron being prone to bolting, but am still growing it for flavour.

On the whole, I think it's safe to say, it's not a big problem, bolting decreases yields, but in onions it can be controled if noticed early, pinch out middle thick shoot, bulb won't spoil. :wink:

I grew red onions from seed one year and had less bolting than from setts in other other years.

But as I did not grow both setts and from seed that year, I do not know if it was just a year when not many red onions bolted.

What experience have others had with red onions from seed compared to setts?

Hi, David,

I have got a bit of a similar problem, so cannot report on red ones. I've planted them next to each other, sets and seedlings and I cannot remember which ones had the bolting ones.

Of white onions, sown from seed have not had a single one bolting the last two years, which is the no of years I grew them from seed. :)

I find that the red ones bolt even grown from heat treated sets,doing better from seed this year.

The most common causes for onions bolting are planting too early,a cold spring or most important planting in loose soil. :shock:

It pays to firm up the soil when you plant,and this step alone can put an end to the problem :wink:

I'm with Henry - don't plant sets too early.  

Whether from sets or seeds, remember that any onion with does NOT bolt is an unfulfilled onion - bolting is what they want to do.  Your job as a gardener is to convince them that life is good (plenty food and water), and that they should build up a bit more strength in the bulb before bolting.  Then harvest before they actually do!

So, the tradition of the shortest day, would that then be too early, do you think?

Also, as somethiing particular to onions is being dug up by wild life, if that happens a few times, that would stress them out, me thinks. This does not happen to seedlings.

But nobody seems to sing the praises of the heat treated ones. :roll:
