Japanese larch

Japanese larch should be watered deeply once a week during the growing season (April-September). Ideally, the soil should be allowed to dry out between waterings. Water the larch until the top 12 inches of soil is moist but not soggy. In hotter months, the plant may need more frequent watering. In cooler months, reduce watering to avoid root rot. Always check the soil before watering; if still slightly damp it may not need water.

Japanese larch (Larix kaempferi 'Stiff Weeping') thrives best in full sun to partial shade, which is 5 to 6 hours of direct sunlight per day. If the tree receives more hours of direct sunlight, it will thrive. If the tree receives too little sunlight, it may become weakened from the lack of energy and start to decline. During the summer months, the Japanese larch needs plenty of light for optimum growth and health. When kept in full sun during these months, the Japanese larch can grow and prosper.

Japanese larch should be pruned in late winter after the coldest weather has passed but before leaf buds swell. Pruning should be done cautiously and judiciously, as it can be difficult to repair. Remove dead, broken and diseased branches first, followed by any weak-wooded or crossing branches. Pruning should be no more than 10-25%, and should be done sparingly and gradually over several years. Remember to leave plenty of foliage to ensure good health for the tree.
