Bare root plants are a tricky subject, being neither dead nor alive when shipped, with several months before you can tell whether they will survive or not, and even then it's not easy to decide fairly whose fault it is.
Did your supplier offer any sort of guarantee in the event of failure?
That's exactly what we're afraid of, by the time you can tell it's too late to do much and they can say it's your fault, you should have complained earlier.
I ordered my raspberry canes from Blackmoor nurseries, and they came with a replacement undertaking should they fail to grow in the first year following planting, as long as I can prove they were treated and planted correctly.
That could clearly be tricky, and presumably I'd also have to wait until the following winter for any replacements, but then again the canes appeared to have been carefully harvested and packed, so no reason to be concerned at this stage.
If your trees came without a similar guarantee, I suggest you make sure you give them written notice about your concerns and your intention to demand a refund should any of them fail to survive.
