光照與放置位置

需要明亮的間接光或半陰環境。直射陽光會導致葉片灼傷和卷曲。

澆水

保持土壤微濕，但避免過濕。缺水會導致葉片卷曲，過濕則會導致根腐。

溫度和越冬

保持室溫約18～24℃，濕度約60%。冷風會使葉片變褐色，冬季應遠離窗邊。

關於條紋竹芋

Calathea ornata is known for its pinstripe-patterned leaves in pink, white, and deep green. This humidity-loving perennial from Colombia and Venezuela folds its leaves at night and suits intermediate growers.

開始照料條紋竹芋前需要了解的7件事

1. 1Bright, Indirect Light

   Direct sun can scorch the leaves and dull that pinstripe pattern, so place it in bright, indirect light such as behind a sheer curtain. Too little light will fade the leaf color, so aim for a spot with steady, gentle brightness.

2. 2Watering and Misting

   Water thoroughly once the surface soil feels dry, and avoid letting it dry out completely. Since it favors high humidity, regular misting of the leaves helps too. At the same time, constantly soggy soil from overwatering puts stress on the roots.

3. 3Well-Draining, Moisture-Retentive Soil

   A mix that drains well but still holds some moisture suits this plant best. Blending general houseplant potting soil with leaf mold or peat moss helps keep the roots from sitting in excess water.

4. 4Repotting Timing

   Repot into a slightly larger pot roughly every one to two years. Roots emerging from the drainage holes or slower water drainage are signs it has become root-bound. Repotting during the warmer growing season puts less stress on the plant.

5. 5Seasonal Temperature and Humidity Care

   It is sensitive to cold, so in winter keep it away from chilly windowsills and direct airflow from heating or air conditioning. During dry spells, a humidifier or extra misting helps prevent the leaf tips from browning.

6. 6Choosing a Healthy Plant

   Look for a plant with firm, taut leaves and a crisp, well-defined pinstripe pattern. Avoid ones with dried leaf tips or many yellowing leaves, and check that the base feels sturdy rather than loose in the soil.

7. 7Leaves Closing at Night Is Normal

   Calathea ornata raises and folds its leaves at night, then opens them again in the morning. This is a natural trait rather than a sign of a problem, so there is no need to worry if you notice this movement for the first time.

條紋竹芋的常見問題

Q.Can it be grown in direct sunlight?

A.Strong direct sun tends to scorch the leaves, so it is not ideal for this plant. Bright, indirect light such as behind a sheer curtain is a better fit.

Q.Does the plant closing its leaves at night mean it's sick?

A.No, this is a natural characteristic of Calathea ornata. The leaves rise and fold at night, then reopen in the morning.

Q.Why do the leaf tips turn brown and dry?

A.Dry air and insufficient watering are common causes. Misting to raise humidity and watering promptly once the soil surface dries can help improve the condition.

Q.What should I watch for over winter?

A.Since it is sensitive to cold, keep it away from chilly windows and direct heating or air conditioning drafts. The air tends to dry out in winter, so a humidifier or misting helps maintain humidity.

Q.How often does it need repotting?

A.As a general guide, repot into a slightly larger pot every one to two years. If you notice signs of being root-bound, such as roots emerging from the drainage holes, you can repot sooner.
