Remove your young lychee tree from its nursery container. Do this gently so as not to damage the roots of your tree.
Fill the new container one-third of the way up with a mixture of potting mix and organic fertilizer such as peat moss and compost.
Place the tree root-side-down into the container. Hold the tree in place as you fill the container the rest of the way with a mixture of potting mix and organic fertilizer such as peat moss and compost.
Place the potted tree into a sunny location, such as a room with bright windows that receive full sun exposure or on a full-sun deck during daylight hours. Turn the tree if it receives sun exposure on only one side, to ensure the tree receives sunlight on each side.
Water the tree thoroughly each day. Container lychee trees often dry out very easily, which may result in leaf drop.
Treat the soil of the tree with a mycorrhizal fungi treatment and add earthworms to replenish the soil. Doing so keeps the soil and the tree healthy, maintaining your tree's life for years to come.
Pollinate the flowers of the tree so that it bears fruit. If you set the tree outdoors during the daytime, insects pollinate for you. If you leave the tree inside all the time, purchase a manual pollinator and pollinate the flowers yourself.
Repot the tree each year, selecting a new pot that is just large enough to hold your tree while giving the roots slightly more room to grow. Trim the roots of the tree while you have it out to for repotting. Trimming the roots prevents the roots from matting together and eventually killing the tree.
