肉質天竺葵

肉質天竺葵的基本資料

栽培難度

適合高級者

壽命

壽命長的多年生植物（壽命資料有限）

體型

高度約60cm（最大可達1.2m）

澆水

生育期施肥1次，使用稀釋的低氮多肉植物肥料

休眠期管理

冬型植物，秋季至春季生長，夏季落葉休眠。澆水時期為春季（2-4月）和秋季（8-11月），盛夏和深冬保持乾燥。

光照和擺放位置

自然生長在岩石縫隙或其他植物的蔭蔽處，因此夏季應置於明亮的半蔭處或只有朝日照射的涼爽位置，並保持通風良好。

澆水

澆水時期以最低溫度14℃以上為基準。過度澆水會使株型變形，過茂的葉片容易患病。

溫度和越冬

避免霜凍，在乾燥狀態下保持最低溫度8℃以上。

介質和換盆

使用幾乎不含有機質的介質。由於不喜歡換盆，應在同一盆中長期栽培。

肥料

肥料以生育期施肥1次為限，使用低氮多肉植物肥料，用量應低於建議濃度。

關於肉質天竺葵

Pelargonium carnosum is a winter-growing caudiciform succulent from southern Africa, prized for its thick grey-green stems and finely divided soft leaves. It sheds its leaves and goes dormant in summer.

開始照料肉質天竺葵前需要了解的7件事

1. 1Light & Placement

   During the autumn-to-spring growing season, give it strong light with good air circulation outdoors or by a bright window. During its leafless summer dormancy, keep it out of direct sun in a spot that won't stay damp.

2. 2Water Sparingly in Spring and Autumn

   It is a winter grower that grows from autumn to spring and drops its leaves in summer, but watering is done in spring (February to April) and autumn (August to November), keeping it dry in midsummer and midwinter. Water only when minimum temperatures are at least 14°C. Too much water ruins its naturally compact shape and makes lush foliage prone to disease, so err on the sparing side.

3. 3Low-Organic Soil

   Use a free-draining mix with almost no organic matter. Limit feeding to one application during the growing season of a low-nitrogen succulent fertilizer, diluted weaker than the label rate.

4. 4Keep Repotting to a Minimum

   Pelargonium carnosum dislikes being repotted, so keep it in the same pot for as long as possible. Choosing a free-draining mix and pot from the start makes this easier.

5. 5Summer Leaf Drop Is Normal

   As temperatures rise in summer, the plant sheds its leaves and rests as a bare stem. This can look alarming, but it's a normal part of its cycle — there's no need to water more or worry.

6. 6Watch Cold Tolerance in Season

   Despite being a winter grower, it's still sensitive to hard frost even during its active autumn-to-spring period. Bring it to a bright spot indoors when temperatures drop sharply.

7. 7Choosing a Healthy Plant

   Look for a plant with a thick, firm, grey-green stem showing clear knotted texture. If you're looking during the growing season, well-developed leaves are another good sign of vigor.

肉質天竺葵的常見問題

Q.All the leaves fell off in summer — is it dying?

A.No, this is normal dormancy. Pelargonium carnosum is a winter-growing species that sheds its leaves and rests during the hot summer months. As long as the stem stays firm, there's no cause for concern.

Q.Can it stay outdoors in winter?

A.Even during its autumn-to-spring growing season, it's sensitive to hard frost. In regions or periods with sharp temperature drops, it's best moved to a bright spot indoors.

Q.How large does it grow?

A.It typically reaches about 60cm in height, with larger specimens growing to around 1.2m. Growth is slow, and the plant's character develops gradually over time.

Q.Is it suitable for beginners?

A.It's generally considered an advanced-level plant. Getting the winter-growing watering rhythm right takes some practice, so it suits growers who already have experience with succulents or caudiciform plants.

Q.How often does it need repotting?

A.It dislikes being repotted, so the basic approach is to keep it in the same pot for as long as possible.
