Anyone? Almost went to page 2 with no replies so I had to bump :)

I have always cut mine back in the spring, when they show new growth. Did you cut a length of the stem off when you deadheaded? This could be why no new flower buds have formed yet. I am finding secondary buds coming on the ones I just deadheaded, just taking the spent bloom off and not much stem.

I do a pretty hard deahead because the Shastas I have are quite tall, and tend to flop over. I do get some secondary flowering, but I think that's from volunteers, because you can't possibly get all the seeds. At the end of the fall,sometimes earlier, I cut them all back to about 6 inches. I do not really expect a second bloom, so I have some sort of annual in front of them to hide what's left, because it ain't pretty!!

I've never gotten a second bloom from Shastas.

Shastas are basal rosette plants that send up tall flower stalks. The flower stalks die off after flowering, so they get cut back to the bottom. It looks like that is the browning in the pictures - the top of the flower stalks beginning to die off. However, it is very hard to get any perspective from the pictures.

So glad to see others with Shasta daisies that peter out in early July... is there something I should be doing to make them last longer? We've certainly had plenty of rain this year, that's for sure!
