What do you need to do to onion plants while they are maturing in
order for them to grow into large slicing onions?

You need to choose the right varieties for your location, long
day/spring
planted in the north, short day/fall planted in the south. ZThere are
some
'day neutral' onions that can be grown north and south ('Super Star'
is an
All American Winner in this class). ...

A better term for Candy and Super Star might be "intermediate day".
In Phx AZ I've been trying Super Star since its introduction as an AAS
winner in 2001 and Candy a few years before that. Get a few 3 inch
bulbs but most either go to seed or stop growing when it gets too hot.
The short day varieties like Grano and Granex (Vidalia type) are pretty
reliable here. Our onion season is pretty much over with. Still have a
few Granos going for seeds. -Olin
