Your young tree should be watered regularly for its first couple years, until it becomes well established. Be sure to allow at least 10 feet of space between your mountain ash and surrounding plants.

Our Mystery Plant (Mountain ash, Rowan, Sorbus americana) has a close relative in Europe, another species which looks very similar to ours. This species is beautiful all year long.

Some mountain ash, or rowan as it is also known, have the berries stripped off by pigeons as early as August, soon after the berries have begun to colour and the tree is still in full leaf.
