Decaisnea fargesii, the blue sausage fruit, blue bean shrub, or dead men's fingers, is a member of the family Lardizabalaceae, and is native to Nepal, Tibet and China. It is a deciduous shrub that grows to 4 m tall and broad, but may achieve 8 m (26 ft) eventually.
The Blue bean tree is well resistant to disease and is generally not susceptible to illnesses. Regarding upkeep, this plant is fairly low-maintenance. Planted outdoors, it needs little watering, and larger specimens typically do not require pruning. Smaller plants should be pruned after they finish blooming. The Blue bean tree is suitable for anyone with an outdoor area, such as a garden or deck, and does not demand extensive care experience.
How to keep Decaisnea Fargesii.
Light
The blue bean tree does best in abundant sunlight, which fosters strong health and growth. Native to areas with plenty of daylight, it is not well adapted to shade. Throughout its stages of development it consistently requires ample sun exposure. Both too little and too much light can harm its vitality.
Temperature
The blue bean tree is an unusual plant native to cooler regions but can tolerate temperatures from 59 to 95 °F (15 to 35 °C). It prefers moderate conditions; too much heat or cold can impede its growth. In extremely cold periods, consider moving it to a warmer location to meet its temperature requirements.
Fertilizer
The Blue bean tree plant needs sufficient nutrients to achieve optimal fruit production. Apply fertilizer in early spring to promote new growth and flowering. Regular fertilization keeps the plant healthy, produces tastier fruit, and prevents nutrient deficiency problems like yellowing leaves and poor fruit production.
