I have 3 cardinal mountain ash trees that won’t flower.
Each tree was bought 1 year apart and they haven't flowered yet. How to pollinate trees if they haven't flowered yet? Trees are around 12+ feet tall
Grows best in full sunshine with moderate amounts of water during the growing season. If your tree is young, it may take a few more years before it's mature enough to produce berries. If it's been established for 4-5 years and is still not blooming, it may need more sunshine or additional water during the growing season.
