How do you know when hey are ready to be picked. They are all black as of now but seem small. Does anyone have a pic of a berry thats ready with some sort of scale to go by like with a tape measure or in their hand? Should they be the size of a small blueberry or big Blueberry? I dont want to miss out on these this year as Ive found a few plants which are wild and may even try to transplant these when they go dormant.
