Cascade Delight Raspberry

I have Tulameen raspberry and has a cane die off disease. I would like to replace with similar resistant variety. Can I order enough for a 50ft row

You will only need like 25-30 canes, so that should be fine

Do these have a finite lifespan? I've been growing 'Cascade Delight' for 14 years and they are lovely, but most of my row have died off over past 3 years while 'Willamette' variety in same row are thriving and filling the empty space? They show no signs of disease and produce heavy but one-by-one just don't throw up usable primocanes anymore. Then over a year or two the bases die off. If old age is a thing then I want to order more. But I don't want to waste the money/time if it's some other problem. Any ideas?

The short answer is yes. Typically a raspberry crown reachs the end of it's peak productive life at 4-5 years and declines after that.

can these be planted in containers?

They can yes. They will grow to 8 feet tall however so be prepared for that.

is the cascade delight raspberry thornless

Raspberries don't have really have thorns, but do have stiff hairs that can occasionally poke you. The only hairless/thornless raspberry is the Bushel and Berry Raspberry shortcake.

do you send only one cane or a group of 3?

We can send as few as one cane, yes.

Is this raspberry RBDV immune?

No, you will need something like Caroline for Heritage for resistance to RBDV. Please note that, like any virus, RBDV is prone to mutation and cultivars currently considered resistant or immune may not be in following years.

I purchased the cascade delight raspberry barefoot canes in February of this year and some of them are 9 feet tall which is nearly double the described height. What could cause that?

Good soil and lots of water. Congratulations!
