贵石斛

贵石斛的基本数据

养护难度

适合中级者

寿命

多年生，通过分株或高芽可以长期更新（寿命信息资料较少）

体型

花径最大约7.5厘米

浇水

春夏生长期施肥，秋季以后停止施肥

光照和摆放位置

春秋冬季应在光照充足处栽培，仅在盛夏需遮挡强光。光照不足会导致难以形成花芽。

浇水

春夏生长期充分浇水，秋季叶片开始泛黄后大幅减少浇水。

温度和越冬

分布范围从凉爽山地到炎热低地，对温度变化的耐受范围较广。秋季经历低温后，霜冻来临前移入室内。

基质和换盆

用水苔或树皮种在较小的花盆中。换盆应在花谢后、新芽开始伸长时进行。

休眠期管理

秋冬季明显减少浇水和施肥以促进休眠，这对来年春季的开花效果至关重要。

关于贵石斛

The wild species behind Nobile-type Dendrobium hybrids. Its upright, yellow-tinged canes bear waxy, fragrant flowers in clusters of two to four, ranging from white to pink and purple. Suited to growers with some orchid experience; propagate through division or keiki.

开始养护贵石斛前需要了解的7件事

1. 1Plenty of Sun From Spring to Autumn

   From spring through autumn, grow it in a sunny spot; too little light makes it reluctant to set flower buds. Shade it only from the strongest midsummer sun. After letting it experience cooler temperatures in autumn, bring it indoors before the first frost.

2. 2Adjust Watering by Season

   Water generously while new growth is actively developing. From autumn onward, cut back gradually, and keep the plant on the dry side through winter — this dry rest period helps trigger flower buds.

3. 3Use a Well-Draining Mix

   Dendrobium nobile does best in a fast-draining medium such as sphagnum moss or bark. Constantly soggy potting mix can lead to root rot, so avoid letting it stay wet.

4. 4Repot After Flowering

   The best time to repot is right after flowering ends, before new roots start to grow. If you're dividing the plant, doing it at this point gives it the best chance to settle in quickly.

5. 5Winter Chill and Dryness Matter

   A cool, dry period in autumn and winter encourages Dendrobium nobile to set flower buds. If it's kept too warm and moist during this time, it tends to produce keiki (side shoots) instead of flowers.

6. 6Choose a Plant Carefully

   Look for canes that are plump and firm, without wrinkling or dark patches. Healthy leaf color and roots that are well anchored in the pot are also good signs.

7. 7Renewed by Division or Keiki

   After a few years, new canes form at the base and the plant grows larger, at which point it can be divided to start fresh plants. Keiki that appear along the canes can be cut away and potted once they've grown their own roots.

贵石斛的常见问题

Q.Is this a good orchid for beginners?

A.Dendrobium nobile is generally considered suited to growers with some orchid experience. If you're new to orchids, it may help to start with an easier species first and build up your skills before trying this one.

Q.What do the flowers look like and smell like?

A.The flowers have a waxy texture and a light fragrance. Colors range from white to pink to purple depending on the plant, and even the same plant can look a little different from one season to the next.

Q.How many flowers does each cane produce?

A.Flowers appear in clusters of two to four at each node along the cane. Since a single cane has several nodes, a well-grown plant can produce a good number of blooms overall.

Q.Why does my plant grow keiki instead of flowering?

A.If the plant is kept warm and moist through autumn and winter, it tends to produce keiki (side shoots) instead of flower buds. Giving it a cooler, drier period during this season encourages flowering instead.

Q.How can I propagate this plant?

A.Once the plant has grown large enough after a few years, you can divide it into separate plants. You can also cut away keiki once they've developed their own roots and pot them individually.
