Q.Blueberry plant and raspberry not producing
I didn’t realize that blueberry plants need another variety to pollinate each other. How long will it take for the non producing bush to have blueberries? And do raspberry bushes also need another variety to pollinate?
Some varieties of blueberry are self fertile, and some aren't, so you need to find that out when you purchase a blueberry plant. However, there can also be cultural reasons why you're not getting fruit. This article will help you check on that: https://www.gardeningknowhow.com/edible/fruits/blueberries/growing-blueberry.htm
As for raspberries, most of them are self-fertile, but most people find planting at least two varieties brings in better fruit. This article has more information: https://www.gardeningknowhow.com/edible/fruits/raspberry/care-of-raspberry-plants.htm
