We are getting a good yield from basically 2 Blueberry bushes.
The 2016 crop yielded 44 quarts, and the 2017 crop was 32ish quarts due to a late freeze. There is a 3rd bush on the right in the pictures, but it has been removed due to poor quality and low yield.
We were getting maybe 8-10 quarts total per year due to hungry birds. So I built that cage in time for the 2016 bloom. It is 6' high x 22 long and 14 deep.
Blueberries are very labor intensive. At least ours are. Very rare for us to pick a cluster. Usually just 1-3 berries at a time.
They thrive in Georgia heat and like water at least once a week, and rich acid soil.
We gave away 29 quarts of the 2016 crop when the 2017 crop started coming in. Looks like maybe 10 to 12 quarts this year of the 2017 crop to give away, as there weren't as many harvested in 2017. We are indeed being blessed, so we share.
Most of ours are used in morning smoothies. With the occasional cobbler, etc..
Don't know if I will live long enough for the Berries we eat to pay for the cage, but learned long ago the cheapest way to go for veggies is the grocery store. This is just a hobby that didn't cost too much to get into, and actually pays us to participate. Only expense now is our time, a couple cups of fertilizer, and some water.
