Should I water me onions????

I noticed last night that one of my autumn sown Japanese numbers had bolted.  It has been so dry lately and I have tried to resist watering, but should I give them some, or is it the heat rather than the drought (?sp)  making them/it bolt?

I gave mine a splosh the other day directed very close along the row... they need to put on some weight fast 

when and onion bolts does it actually flower? The leaves on mine have grown really quick in the heat and are not very strong?

i water my onions when i water all my seedlings

Yes, to bolt means to go to seed (which means, flowers).
If the leaves on your plants don't look too robust, then give them a feeding of either your favourite veg fertilizer, or a mulch of some rotted manure or compost, or a good drink of comfrey or nettle tea.

I've never watered onions, but I do make sure the soil is good and water-retaining, with lots of organic matter and mulch where appropriate.

I've just mentioned it in another post, but it would be good if people could try leaving a small area of a crop unwatered, to see if the end results are really much different. I think people tend to water unnecessarily and we're all going to have to get used to water becoming more scarce. You'll find many traditionally-run large gardens don't use water apart from for seedlings, after transplanting, etc.
