Anyone here growing Boysenberries in zone 6?

General Fruit Growing
1

I have 3 boysenberry plants that I got from Stark Bros and have been growing in pots on a trellis since last year. They’re 6-7 ft tall now, and getting out of control, but I’ve gotten no fruit so far. I wanted to taste them before putting them in ground to make sure I like them. Anyone growing these in ground in z6? Are they worth growing or would I be better off with a good blackberry instead? Looking for feedback.

Here is a review from 10 years ago… from Z6A

Boysenberry: Best fresh tasting berry I have ever eaten out of the

Old garden. This is the second year and immediately after eating

My first set of berries I purchased 3 additional plants. Thorned

Variety is very hardy and performs well in my 6a zone.

Thank you so much for this. I’ll give them a whirl. I think I’ll overwinter the 3 x 8 gallon boysenberries in my unheated garage this winter and plant them in ground next spring.

I would be tempted to plant one in the ground… maybe spray some wiltstop on it… or cover it with burlap or frost cloth… and probably plant one as is…unprotected… could save you a year of trial and error.

We never know if we are going to have a mild winter or the worst winter in decades…

I’m afraid the roots won’t be established enough to withstand our winters here in MA if I transplant now.

Not trying to sway you one way or another… but this is almost never discussed.

a point to consider…

IF that boysenberry tip rooted…around this time of year…it would continue to grow roots all fall…into winter…and in the spring time if you tried to dig it up there would be roots everywhere… it is its own method of propagating…

I am no expert by any means…but it does seem that cane fruits prefer to grow roots in the fall and thru winter by their own propagation… to have that explosion of growth in the spring…

Only a handful of fruit tree vendors sell for fall planting due to the nature of us humans to want things to be planted in the spring…

Maybe there is some science out there to justify one or the other?

I do know that Rubus does is own natural propagation Fall/Winter… and focus is on vegetative biennial growth in the spring/summer.

I have had some success planting blueberries in the early fall in a hole I dug and sulfured in the spring.
