I purcahased a beautiful black lace elderberry plant at the arb plant sale. The location I want to plant it in, surprisingly has large, lateral roots, 2-3 feet deep from a birch tree about 5 feet away. Would they interfere with the elderberry’s ability to obtain sufficient water & nutrients? Or do these roots get their nutrients more from their ends? Do I need to find another place for the elderberry or consider removing some of the tree roots?? Thank you for any insights!
