岩月(Tylecodon wallichii)

岩月(Tylecodon wallichii)的基本数据

养护难度

适合中级者

寿命

生长非常缓慢，寿命长（有关寿命的资料较少）

体型

高度约50厘米（偶尔达1米），茎干粗度可达6厘米

浇水

生长期施用稀释的高钾肥料

光照和摆放位置

最好放在光照充足的地方，但在半日照环境中也能生长并开花。

浇水

冬生型。在晚夏至早春的生长期，当根部土壤几乎干燥时浇水。冬季寒冷时期应减少至大约每两周浇一次。

休眠期管理

晚春至夏季植株落叶进入休眠，此时应停止浇水并保持干燥。

温度和越冬

冬季最低温度应保持在5℃，最好在8℃以上。温度过低会导致叶片容易脱落。

用土和换盆

使用排水性极好的土壤（腐叶土与细碎树皮、河沙、轻石各半混合，或排水性好的仙人掌专用土），每2～3年混入缓效肥料进行一次换盆。植株基部应露出土壤表面，膨胀的茎干不要埋得过深。

病虫害和注意事项

整个植株，尤其是叶片含有强毒性，会导致家畜中毒。应将其放在儿童和宠物够不着的地方。容易受到介壳虫侵害，应定期检查分枝基部。

关于岩月(Tylecodon wallichii)

A winter-growing caudiciform succulent whose thick trunk is covered in yellow-green, wart-like bumps, with narrow leaves and urn-shaped summer flowers. Very slow-growing and best suited to intermediate growers.

开始养护岩月(Tylecodon wallichii)前需要了解的7件事

1. 1Light & Airflow

   During its winter growing season, place it outdoors or by a bright window with good airflow. In summer dormancy, avoid direct sun and keep it in bright, indirect light to prevent excess humidity around the plant.

2. 2Water on a Winter Cycle

   Its growing season runs from autumn through spring while leaves are present; water thoroughly once the soil has dried out. During summer dormancy, when the leaves drop, hold back on water and keep the soil on the dry side.

3. 3Well-Draining Soil

   A well-draining mix formulated for caudiciform or succulent plants, based on pumice or akadama, works well. Good drainage at the bottom of the pot also helps prevent root rot from excess moisture.

4. 4Repot During the Growing Season

   Repotting is easiest on the roots when done during the growing season (autumn to spring), while the plant is in leaf. Gently loosen the root ball, trim away any damaged roots, and replant in fresh, well-draining soil.

5. 5Summer Dormancy Care

   In summer, when the plant is leafless, it enters full dormancy and growth essentially stops. Keep watering minimal and place it somewhere cool with good airflow to reduce stress on the plant.

6. 6Choosing a Healthy Plant

   Look for a plant whose trunk and branches show a dense, well-formed covering of wart-like bumps, with no wobble at the base. If it's in its growing season, healthy leaf color is another useful indicator of condition.

7. 7A Slow, Long-Term Grower

   Because growth is extremely slow, this isn't a plant for anyone hoping to see dramatic change in a short time. It suits growers who enjoy nurturing a sturdy, characterful trunk over many years and don't mind taking things slowly.

岩月(Tylecodon wallichii)的常见问题

Q.Is Tylecodon wallichii suitable for beginners?

A.It's generally considered an intermediate-level plant, since it requires learning succulent-specific care such as adjusting watering around dormancy. Growers with some prior experience with caudiciform plants will find it manageable.

Q.Why does it lose its leaves in summer?

A.Tylecodon wallichii is a "winter grower" — it grows during the cooler months and goes dormant in summer, shedding its leaves as part of that cycle. This is normal behavior, not a sign of illness.

Q.How large does it grow?

A.It typically reaches around 50 cm in height, occasionally up to 1 m, with a trunk that can thicken to about 6 cm. Because growth is extremely slow, reaching these dimensions takes many years.

Q.When and what kind of flowers does it produce?

A.It blooms during its leafless summer dormancy, producing small, urn-shaped, yellow-green flowers that hang from the branch tips. This flowering period falls outside its normal leafy growing season.

Q.What are the wart-like bumps on the trunk?

A.They're raised tissue left behind where old leaves have dropped, and they become more pronounced as the plant matures. This textured trunk is one of the plant's signature features.
