To start, you’ll want to dig a large enough hole for your tree so that its roots can have plenty of room to spread out. Then, gently place your Mountain Ash into the hole and back-fill the soil around it, making sure you don’t compact the soil too much. Lastly, water your tree to help it get off to a healthy start.

Caring For Your Mountain Ash
