Q.Why does my elderberry plant have real small berries?
The plant is over 6 ft tall and lots of limbs. It looks really healthy and got so many clusters of flowers.Now it has berries but they are small and still pretty green. I thought that would be the size of small peas atleast. Is there a reason the berries are small? Should I cut it back this fall? Thanks very much.

When they are fully ripe, they will be the proper size, and will turn dark or red. This article will help you to know when to pick these: https://www.gardeningknowhow.com/edible/fruits/elderberry/tips-for-picking-elderberries.htm
