Trees need to be planted in early spring or late autumn. Spring planting is better because the soil is still warm enough to allow the roots to spread out. Fall planting allows the soil to dry up so the roots can grow deeper into it. Digging holes wider than the rootball helps prevent the tree from sinking. Removing the rootball from the container should be done by carefully lifting out the entire rootball without breaking it into pieces. Then you should tease it apart before setting the rootball upright in the hole. After backfilling the hole, you should lightly tamp the soil to make sure there are no air pockets. You should give the area about an inch of water, and then apply two or three inches of mulch.

  • Soil Needed: The plants do best in moist, fertile soil. They also need well-drained soil. Plants do not do well when exposed to salt or fertilizer.
  • Fertilizer: Trees take up nutrients when they grow. Fertilizing them too soon after planting may cause the tree to grow weakly. Watering and fertilizing during the growing season promote healthy growth.
  • Pests and Diseases: This plant spreads very easily and can impact the landscape, so please consider planting native plants or dwarf varieties that do not bear fruit. Leaves and berries are toxic to livestock and other domestic animals. Fruits contain cyanide, which is toxic to birds if ingested in large quantities.
