onions bolting
« on: May 20, 2011, 10:04 »
We were given around 60 small onion plants grown from seed by our neighbour.  We were going along fine, had heavy rain for Feb March and virtually all of the onions have thrown up flowers!  Pretty as they are we wanted onions!  Its not only us with onion flowers, all the neighbours have the same problem! I think we have 6 non flowering onions!
Is it due to the weather or the seeds?

hi
had similar problem,be vigilant and pick off flower heads as soon as you see them developing,seems to work for me,hopefully the energy will then go into developing bulbs
good luck

Yes they will develop bulbs, but you're always going to have that bit of flower stem inside the bulb that will rot quickly once they're lifted, hence the bulbs won't store well.
Did it really tell you to do THAT on the packet?

What causes them to bolt?  Is it the wet ground we had?

It's usually the3 dry spells that do it.

This is John's take on it:

Whilst most likely to be the weather over fertilising can also contibute to it

We had a quite dry December into january and the rains started towards the end Feb, so that is probably the problem.  I didn't fertilise as we were not expecting to plant.
Many thanks!
