Soil Type

Water: Amur Cork Tree originates from East Asia and adapts to low moisture. It requires watering every two weeks, with reduced needs in winter dormancy and increased demand in spring. Thriving outdoors, amur Cork Tree prefers consistent moisture but tolerates moderate drought.

Fertilize: Amur Cork Tree thrives on balanced nutrition through bi-annual fertilization during the growing season, with higher nitrogen in early development. Adjust nutrient intake according to seasonal changes and avoid over-fertilization. Water the soil prior to application to enhance nutrient uptake.

Pruning: Amur Cork Tree is a deciduous tree with corky bark and vibrant yellow fall leaves. Prune in early spring, removing dead and crossing branches to enhance air circulation. Avoid heavy summer pruning to prevent stress and promote healthy growth and aesthetics.

Propagation: Amur Cork Tree is a resilient tree prized for its ornamental and medicinal properties. For successful propagation, sow seeds immediately after collection to prevent viability loss. While stratification can aid germination, it is not essential. Alternatively, late summer semi-hardwood cuttings provide a reliable rooting method.
