Horticultural Information (bonsai specific):

Placement

The Larch and the Golden larch grow best in full sun, preferably semi-shaded in summer during the hottest hours. Larix trees are very frost hardy trees, but they should be protected from excess rain in winter. The Pseudolarix prefers semi-shade during hot summer weeks and should be protected from drying winds. It is not frost hardy and should be kept in a cold frame during winter.

Watering

Larches must be watered thoroughly when the soil gets dry. The Pseudolarix needs a lot of water and should be kept moist, never let the rootball dry out. In summer the pot of the Pseudolarix can be placed in a shallow water bowl to ensure sufficient moisture on hot days. Larix and Pseudolarix both don't like very calcareous water.
