This tree seem to love sandy soil, being more common here in Coon Rapids compare to Minneapolis and St. Paul, which is made of clayish loam. It seem to be a bit vulnerable to winter burns, especially near roads, so don't plant them near the street due to salts. It also dislike shade, not as strongly as Red Cedar, so don't plant it 30 feet or closer to a large tree - even when the other tree are still about 3 to 4 feet tall. Trees will grow fast, becoming large in 20 to 30 years. They tend to shed, making it difficult for mows to shred the leaves and can be painful to walk on barefoot. Use the area around the tree as a mulch and plant groundcover or maybe even try acid loving plants! (Of course, you need to add acid fertilizers).
