The Chinese Elm can be grown Outdoor or Indoor Tree. If grown outdoors it should be grown in full sun.

To retain and produce small leaves, do not feed high nitrogen fast-acting fertilizers. Feeding three or four times a year is sufficient to maintain good color and healthy growth without enlarging the size of the leaves. Do not feed when tree is without leaf.
Leaf and Branch Pruning:
Most shaping can be done by pruning. Heavy pruning is best left to when the plant has gone dormant just before spring.
Re-potting & Growing Medium:
Repot younger plants every year and older plants every 3-4 years. It can deal with most types of soils as long as they are well drained. Use a deep or larger than normal pot as the tree is well rooted and likes room to grow. Soil Mix: 1 Part Akadama, 1 Part Fuji Grit, 1 Part Leaf Compost, 1 Part Pine Bark.
Not normally necessary most shaping is done through pruning. If wiring is required, be wary as the Branch are quite brittle and the flakes and bark marks quite easily.
