Answer: You are indeed a mimosa's best friend! Mimosas like full sun although they will put up with a little shade, especially later in the day. Give them a site with good drainage.
If you can add compost to a large area of soil, and mix it in about 6-10 inches deep, this will help them take off to a great early start. Only amending the soil in the planting hole is not recommended however, as their roots quickly outgrow this small area. Plus, in a heavy soil like clay this can become a soggy underground pot.
Mulch a wide area around the young, growing trees to protect soil and reduce weed competition. Your trees with respond with rapid growth.
