Mine rarely last more than two years, and recently buy, bloom, die.
I bought a cluster from Beck's last year, and now am waiting to see what survived.
The other half planted them, then I replanted them more the way they should be,so losses will not be a surprise but survivors will be.
Either way I may dig up the whole garden, partly to redo paver stones, that should have been done when the garden was dug up two years ago, that are part of a decoration.
There was not an ice-cap on that garden this year, as there is more often than not, which I am sure causes problems, so I am expecting a better survival rate than I was when I planted.
Irises are putting out leaves now , so I know which are still alive and which are kaput.
With a large empty spot, it will be interesting to see how may, if any , I bought last year came through.
I am going to have to figure out where to put some for next year as between tulips and iris a lot of empty holes plus Sharon just bought 8 Peony for this fall and she is going to redo a lot also.
That empty roof drip line is annoying ; if I could find a not ugly, according to Sharon, way of saving the water I would.
I may spend bigger bucks for a full wine or whiskey barrel/s to put there.
