i want to plant a blueberry bush in a pot. I read that you need 2 bushes because of pollination. Is this right?
Yes, or at least if you want good pollination you do. And two different clones too!
Do I have to plant one in each pot
Unless it's a huge pot yes I would say so.
Go to Dorset Blueberry Company/Trehane Nursery for good information about which types to choose.
We have had a bumper crop this year too - netted them for the first time. We were picking from mid June til early August. I have two plants of the same variety - Earliblue
