<human>:  How do I plant a tree?
<bot>: To plant a tree, start by selecting a location that provides adequate sunlight and water drainage. Dig a hole twice as wide as the tree's root ball but no deeper. Carefully place the tree into the hole, making sure that the root ball is level with the surrounding soil. Backfill the hole with soil, and press the soil around the tree firmly. Water the tree deeply and add a layer of mulch to help retain moisture and reduce weed growth.
