Hi, I have been growing glads for a few years now, and I never do anything special for them, they always come out beautiful. Sometimes they may need staking when the blooms open. I never fertilize.
Good luck!

I agree, prepare for staking or they fall over when in full bloom. Al

Thanks for the input, folks.

>prepare for staking or they fall over when in full bloomSo what do you use for staking? I have between 50 and 100 glads in a bed. Would you stake each and every one? Or do you suspend some kind of netting among them?

Depending on the shape of the bed I would run strings through between the plants at right angles about two feet off the ground. Pick a material as invisible as possible. Once they start falling over it will be difficult to do. Al

>Depending on the shape of the bed I would run strings through between the plants at right angles about two feet off the ground.Will just one layer of support at about 2' off the ground do the trick? I was thinking of perhaps using garden netting like the one pictured a the URL below.

All your glads should end up blooming at about the same height and I don't see the need for more than one level of support. The netting looks like it would fine, but you will need to have it high enough to be effective and each glad will need to be hand directed into the net. Al

I plant my glads in amongst my Oriental Lilies. The lily stems are very stout & support the glads as well as, or better, than staking & don't look as intrusive in the garden.

Wish I could grow lilies of any kind and not just to help support glads.

Deer nip flowers off an entire stand in one night.

A neighbor had them interplanted with Pachysandra and they're were gorgeous. I mean about 100 lilies. Gone in one night. They're coming up again this year and everyone is just waiting for them to bloom as they're stunning but it's painful to see them all gone one morning as we drive by.
