How long does it take for ripe Blueberries to turn Blue?
Question:We are growing blueberries on a bush and there are these balls of green. When will they turn blue?
Answers:
Here are the developmental stages from flower to fruit ( for the Blueberry):
1.Fertilization of the ovary.
2.Flower swells rapidly for about a month and then stops.
3.Green berry develops with no change in size.
4.Calyx end turns purplish and rest of berry becomes translucent in appearance.
5.Next few days a light purple color begins to develop and then deeper purple.
6.During color change the berry volume increases rapidly.
Intensity of pigmentation increases during the first six days of color change. Therefore most of the anthocyanin (a water soluble pigment that imparts colors ranging from blue to shades of red) is developed in the fruit during this early stage of maturation.
The berries ripen at different times on the same bush. Just don't pick your berries as soon as they turn blue. Let the berries hang on the branches a few more days to develop their full sweetness and aroma.
Once blueberries color up, the fruit will continue to ripen and sweeten for up to a week on the bush. If you need to pull at a berry to get it off the branch, it's not ready yet.
ripe blueberries are already blue. If they're not blue, they're not ripe.
picking is best the last 2 weeks of August..so it takes about a month for them to ripen
It depends on the weather and your geographic location. I advise buying a net to keep the birds and squirrels away from the berries.
Native berries are not ripe here yet either.
