How long after a raspberry Bush flowers does it produce a raspberry?

There are probably 7 healthy white flowers on my raspberry bush (the bush isn't all that big). I don't want to cut them off to promote better growage, I wanna see if they can actually produce fruit. How long from this stage (the flower) will it take to produce a raspberry?


Or how long on a Blueberry bush?





Thanks All !

How long after a raspberry Bush flowers does it produce a raspberry?
That depends totally on whether or not the flowers get pollinated by the bees. If they do get pollinated, it will take about three weeks from flower to fruit.





For blueberries, I'd stretch that time out to about 6 weeks.
Reply:Many raspberry cultivars produce a non-bearing cane the first year, that flowers and grows berries during the second season. "Everbearing"


raspberry plants can bear two crops per year, one crop in the spring and the second crop in the fall. The ever bearing raspberry bushes can produce a crop the first season in the fall on primocanes. Popular everbearing raspberry bushes and vines are: Heritage red raspberry, Autumn Bliss and Amity red raspberries.





A new blueberry bush will produce fruit in the third year. Most large potted bushes are 2 yr olds, so the berries appear the next year.





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.
