I just bought a Kwanzan Cherry Tree and planning to put it in front yard with the Bermuda grass. Can I build a ring around it with stones; maybe around one foot off the ground and fill the ring with soil? Then plant the cherry tree to match the soil line of the ring, so I can plant flowers around the tree. The ring be around 6ft in diameter or smaller. I think planting the tree straight in the yard won’t look good with anything around it. Also, I just took out a Bradford pear tree last week, can I just plant the cherry tree over the stump? It be grounded down a bit. What kind of soil do I feel the ring with?
