Title: Re: [NAFEX] St. Julian rootstock experience?

None of the Hansen hybrids work in the NW.  They are all very susceptible to Pseudomonas in the cold, wet spring, which causes the blossoms to blast and kills back the growth.  Most will grow out again when the weather turns warm and dry, making them look great, but in over ten years, I got about two fruits off of a couple of them.
I tried them years ago when places like Gurney's were still selling them regularly.
