Boysenberry, Blackberry, Raspberry soil PH

ftanApril 4, 2009

I recently bought some Boysenberry plants that should be arriving any day now. Can anyone tell me what that PH needs to be for Boysenberry's to produce? I live in a Idaho where the soil has a tendency to have a PH around 8. Also, what does the PH need to be to successfully grow Blackberries and Raspberries? I have grown raspberries in the past with a lot of success without having to lower the PH. Will they produce even more if I'm able to lower the PH?

I think the first kind will probably not live through your winters anyway. Otherwise

"Monitor your soil pH
closely and keep it between 5.6 and 7.0"

We don't know what zone ftan lives in - Idaho has a wide range (zones 2 to 7), so I would not say that they will not live through the winter. It has not been below zero in over ten years here in Boise. The bulk of Idaho's population is in zone 6. Knowing where ftan lives would help.

Lowering the PH will likely help as the arid parts of Idaho (the parts that make up zones 5,6,7) do tend to have alkaline soil.

I've seen Boysenberry and related forms described as tender in local Extension publications. On the other hand, at least a few commercial web pages claim -10F.

Notice that it is not included in the table of recommended varieties at the pages I linked to above.

I planted Boysenberries years ago, and they failed to winter over in Northern Virginia. We rarely approach zero; never in the last 10 years that I can recall. I think that anything below 10 degrees will take out Boysenberries, or at least seriously damage them to the point they will not produce.

Boysen is one of the more cold-sensitive blackberry varieties. If raspberries have done well in the past without you having to manipulate the pH, I'm sure your Boysen will be fine.
