火把樹

火把樹的基本資料

栽培難度

適合中級者

壽命

長壽命灌木，成熟需時60～100年

體型

高度2.5～6公尺（偶見10公尺），莖幹基部直徑約6公分

澆水

生育期間適度澆水

光照及擺放位置

在全日光至半日光條件下生長最佳。

澆水

生育期間葉片長出時應適度澆水，葉片脫落休眠期間則保持介質乾燥。

介質和換盆

本植物生於乾燥岩場，應使用排水性良好的介質栽植。實生苗具粗大直根，應採用較深的花盆。

修剪和造型

欲展現根部肥厚的外形，可剪除側枝，如此主幹基部會更容易增粗。

繁殖方法

可用種子和插條繁殖。在自生地，將切下的莖插入地面能輕易發根並形成活籬，發根能力極強。

關於火把樹

Fouquieria splendens (ocotillo) is a North American desert plant with spiny stems that leaf out after rain and bear red tubular flowers. In the wild it is a shrub 2.5 to 6 meters tall.

開始照料火把樹前需要了解的7件事

1. 1Light & placement

   Ocotillo thrives in strong, direct sun, so an all-day sun spot outdoors suits it best. If kept indoors, place it by the brightest south-facing window you have and make sure air circulates around it.

2. 2Watering rhythm

   While the plant is actively leafing out, water thoroughly whenever the topsoil dries. Once it drops its leaves and enters dormancy, cut back watering sharply and keep it on the dry side.

3. 3Fast-draining soil

   A well-draining cactus or succulent mix suits ocotillo well. Blending in pumice or hard akadama helps ensure the drainage that keeps roots from rotting over the long term.

4. 4Repotting

   Repot every few years during dormancy to prevent the roots from becoming pot-bound. The roots are delicate, so work quickly, and hold off on watering for a while afterward to let them recover.

5. 5Seasonal care shifts

   Care needs change dramatically between the growing season and dormancy. Give it plenty of sun and water while it's in leaf, then switch to a drier, cooler regimen once it drops its leaves for the season.

6. 6Choosing a healthy plant

   Look for a plant with firm, unwrinkled stems, since shriveling can signal dehydration. The condition of the spines and the base of the stems is another good health indicator, and during the leafing season, good leaf coverage is a useful sign too.

7. 7Cold protection & winter

   Ocotillo enjoys heat but doesn't tolerate cold well, so bring it to a bright spot indoors as temperatures drop. Keep it on the dry side through dormancy so it winters over without excess moisture.

火把樹的常見問題

Q.Is it normal for the leaves to appear and drop repeatedly?

A.This isn't a sign of disease — it's simply how ocotillo behaves naturally. It flushes with new leaves within days of rainfall, then drops them again and goes dormant as conditions dry out.

Q.Can it be grown indoors?

A.Yes, it can be kept indoors as long as the spot gets plenty of light and airflow. It's hard to match the intensity of outdoor direct sun indoors, though, so place it at the brightest window available.

Q.When does it bloom?

A.During its active growing season, clusters of red tubular flowers appear in spikes at the stem tips. Whether and when it flowers can vary depending on the individual plant's condition and growing conditions.

Q.Is this suitable for beginners?

A.It's generally considered an intermediate-level plant to grow. Because watering needs to shift dramatically between the growing season and dormancy, prior experience with succulents or cacti will make it easier to manage.

Q.How large does it grow?

A.In the wild it typically reaches 2.5 to 6 meters tall, occasionally as much as 10 meters, with stems around 6cm thick at the base.
