Aronia Maturity Chart by Sam Pick | Apr 25, 2016 | Harvesting Research | 3 comments Aronia Maturity Chart 3 Comments Dave Emerson on August 11, 2016 at 4:59 pm My name is Dave Emerson. I am growing 2 acres of Viking plants in Harrison County, Kentucky. Our first acre was planted 2 years ago. Second acre was planted last year. I was surprised that the first acre had LOTS of blooms this spring, so I allowed them to fruit. The fruit is now all a dark purple. I have looked at your chart My question is: how can I actually tell it is time to harvest?

A good rule of thumb you can do is order a refractometer($15-25 on amazon). This reads your Brix level. Normally when you get to 18 Brix or above the berries are ready. Some seasons the berries won’t get there. pH is another good indicator, once the juice reaches 6.5pH its another sign they are ready. You certainly can let mother nature tell you too by how easy berries pull off of the plant and cutting into the berries and making sure they are dark purple all the way through.
