Cross pollination of blueberry bushes
After listening/reading to Lee Reich on Mike McGrath's You Bet Your Garden talk about using blueberry bushes as edible landscaping I decided to look into planting 3 Elliot blueberry bushes. Looking into it more I discovered another variety is needed for ideal fruit development via cross pollination.
I have a few questions about the cross pollination.
1. How close do they have to be? (I have a quarter acre)
2. Do you need a 1:1 ratio? Due to their size I was planning on planting 3 Elliot bushes adjacent to my garage because of their ornamental properties and was thinking of plant 1 plant of another variety in a less visible location. Is the 1 plant enough? Or do I need 3 plants of another variety adjacent to these 3 bushes to achieve the cross pollination benefit?
Thanks in advance for anyone's input!
