Keep soil consistently moist but not waterlogged, especially for young or newly planted Acer species. Water deeply when the top 2-3 cm of soil feels dry. Reduce watering frequency during winter dormancy.

Avoid overhead watering to prevent fungal diseases.

Prune in late winter or early spring before sap flow begins to minimize "bleeding. " Remove dead, damaged, or crossing branches. Pruning for shape or size should be done judiciously.

For most Acer species, heavy pruning is not recommended.

Acer species can be propagated by seeds, cuttings, or grafting. Seeds often require stratification (a period of cold treatment). Softwood or semi-hardwood cuttings can be taken in summer and treated with rooting hormone.

Grafting is common for specific cultivars.

Repot young Acer species every 2-3 years, or when root-bound. Mature trees rarely need repotting. Use a well-draining potting mix. Repot in early spring before new growth emerges.

Trim back about one-third of the root mass to encourage new root development.
