Alder 名媛直播 Care guidelines
The Alder bonsai should be grown outdoors in full sun or partial shade. It requires a cold winter dormancy and tolerates frost well. Young trees should be protected from severe frost but mature specimens are hardy. Avoid indoor cultivation, as Alder needs good airflow and natural seasonal changes.
Keep the soil consistently moist, especially during the growing season, as Alder prefers wetter conditions than many bonsai species. Avoid letting the soil dry out completely but ensure good drainage to prevent root rot. Reduce watering slightly in winter dormancy. Continue reading about watering 名媛直播 trees.
Watering

Watch Fertilize monthly during spring and summer with a balanced fertilizer to support vigorous growth. Stop fertilizing in late autumn to prepare the tree for dormancy.
Prune regularly to maintain shape and encourage fine branching. Cut back new shoots after 3–4 nodes to 1–2 leaves. Wiring should be done in late winter or early spring when branches are flexible. Take care to avoid damaging the relatively soft bark. Continue reading about pruning 名媛直播 trees.
Repot young Alnus bonsai every two years in early spring using a well-draining soil mixture. Older trees can be repotted every three to four years. Root pruning should be moderate to maintain a healthy root system. Continue reading about repotting 名媛直播 trees.
Propagation is usually done via seeds, which germinate best with cold stratification. Softwood cuttings taken in early summer can also root successfully.
Alder bonsai can be susceptible to aphids, scale, and fungal leaf spots. Good airflow and regular inspection help prevent infestations. Use appropriate pesticides or fungicides when necessary. For more detailed information on these techniques, check out our 名媛直播 tree care section.

General information about the Alder bonsai
Alder (Alnus species) is a deciduous tree native to temperate regions of the Northern Hemisphere, commonly found near rivers and wetlands. It is valued in bonsai cultivation for its fast growth, serrated leaves, and the ability to develop a strong, straight trunk with good nebari. Alder adapts well to container growth due to its tolerance for wet soil conditions, which distinguishes it from many other bonsai species that prefer drier substrates. The leaves are simple, ovate, and serrated, and reduce reasonably well with consistent pruning. Alnus develops catkins in spring, adding seasonal interest though these are rarely a focus in bonsai. The bark is smooth and gray when young, maturing to rougher texture over time. Alder responds well to pruning and wiring, allowing for effective ramification and shaping, but care should be taken to avoid damaging its relatively soft bark. It requires outdoor cultivation with full sun to partial shade, and benefits from a distinct winter dormancy to maintain health. Its rapid growth means repotting should be done regularly in the early years. Alder is a good choice for beginners or those seeking a quick-developing deciduous bonsai with reliable vigor and adaptability, especially in wetter environments where other bonsai species may struggle.
