Growth Characteristics

Pseudoacakia var. umbraculi-pera is a tree primarily planted for ornamental purposes. Compared to other black locusts, it grows by providing a significant amount of shade. It generally grows to a height of about 5 to 10 meters. While this plant thrives in relatively dry soil, it prefers well-drained soil. Additionally, it requires plenty of sunlight to grow healthily.

Propagation Methods
It is mainly propagated by seeds or cuttings. For seed propagation, mature seeds should be sown in the spring, and the germination rate is relatively high. For cuttings, branches are cut in the summer to encourage rooting; care must be taken to ensure the cut branches retain moisture.

Cultivation Methods - Soil Preparation: Select well-draining soil and mix in plenty of organic fertilizer before planting.
 - Planting: Dig a hole suitable for the size of the roots, and compact the soil firmly after planting. 3. Watering: Initially, provide sufficient water to help the roots establish themselves; thereafter, water only when the soil is dry.
 - Fertilization: Apply fertilizer during the growing season in spring and summer to promote healthy growth.

Uses in the GardenAs a tree capable of providing shade, Umbraculifera is suitable for creating resting areas in gardens or parks. It is also aesthetically pleasing and widely used for landscaping. In particular, it can be effectively utilized to protect other plants or to create harmonious plant arrangements.

Important Pests and Control Methods

Through proper care and careful observation, the occurrence of pests and diseases can be minimized. In addition to this, you can maintain the tree's health through regular pruning and soil management.
