麗格秋海棠

麗格秋海棠的基本資料

栽培難度

適合中級者

壽命

多年生植物

體型

株高和冠幅均約30〜45公分

適宜溫度

16〜21℃

澆水

生育期每2週左右施用一次濃度稍淡的液肥，秋季減少施肥頻率，冬季停止施肥

光照和擺放位置

置於明亮的間接光下，避免強烈的直射日光。若光線單邊照射，應每週轉動花盆一次以保持株形均衡。

澆水

待土壤表面基本乾燥後再澆水，避免過度濕潤。部分品種在秋冬季休眠並落葉，此期間應減少澆水，等待春季新葉萌發。

溫度和越冬

日溫約21℃、夜溫約16℃最佳，低於此溫度會停止生長。相對濕度應保持在50%以上，某些品種需要更高的濕度。

土壤和換盆

使用通透性良好的輕質土壤，植於較淺的花盆中。當根莖從盆邊伸出時應進行換盆。

繁殖方法

可通過根莖扦插或葉插進行繁殖。過長的根莖經修剪後會萌發新葉。

病蟲害和注意事項

葉片保持濕潤容易導致白粉病。秋海棠屬植物含有水溶性草酸鹽（特別是地下部分），犬貓誤食會引起嘔吐和流涎。某些品種可能受植物品種保護法保護，因此在繁殖並銷售或轉讓具有品種名稱的植株前，應確認其是否為登記品種。

關於麗格秋海棠

Discover rex begonias, hybrid rhizomatous begonias grown for their striking silver, red, and purple leaf patterns. With over 500 cultivars, learn their key care basics here.

開始照料麗格秋海棠前需要了解的7件事

1. 1Bright, Indirect Light

   Rex begonias dislike direct sun, which can scorch their leaves. Place them in bright, indirect light, such as near a window filtered by a sheer curtain. Too much direct sun can also dull the vivid colors and patterns on the leaves.

2. 2Water After the Soil Dries

   Water thoroughly once the surface of the soil has dried out. Because rex begonias grow from rhizomes, constantly wet soil can lead to root rot, while letting the plant dry out too much causes the leaves to wilt. Avoid leaving standing water in the saucer beneath the pot.

3. 3Well-Draining Soil

   Choose a soil mix that drains well and allows good airflow around the roots to help prevent rot. A general houseplant potting mix combined with perlite or pumice works well. Avoid pots that tend to trap water at the bottom.

4. 4Size Depends on the Cultivar

   Rex begonias are a group of more than 500 cultivars, so leaf shape, color, and size vary widely. Plant in a light, airy mix in a fairly shallow pot, and repot when the rhizome starts to spill over the edge.

5. 5Repot When Rootbound

   Repot into a slightly larger container when you notice signs of being rootbound, such as roots emerging from the drainage holes or water draining poorly. Repotting while the plant is actively growing, rather than during its slower periods, puts less stress on the roots.

6. 6Watch Temperature in Winter

   It prefers about 21°C by day and 16°C at night, and growth stops below that. Keep it in a warm spot indoors as temperatures drop. Raise humidity with a humidifier or a tray of wet gravel, and keep the leaves dry.

7. 7Choosing a Healthy Plant

   When choosing a plant, look for firm leaves with clear, vivid color and pattern. Avoid plants with browning leaf edges or a loose, unstable base at the soil line, as these can be harder to care for afterward.

麗格秋海棠的常見問題

Q.Can beginners grow rex begonias?

A.Rex begonias are generally considered suitable for gardeners with some experience, since they're a bit particular about light and watering. A first-time grower can still succeed by carefully following the basic light and watering guidelines, though more attention may be needed than with easier houseplants.

Q.Why are the leaves turning brown?

A.Browning leaves are commonly caused by sunscorch from direct light, over- or under-watering, or overly dry air. Reviewing the plant's light exposure and watering schedule can often help improve the condition.

Q.Do rex begonias flower?

A.Rex begonias do produce flowers, but they're grown primarily for their colorful, patterned foliage rather than their blooms. Most growers treat them as foliage plants first and foremost.

Q.How should I keep humidity up?

A.Rex begonias like humidity of 50 percent or more, and some cultivars need even higher. Leaves left wet are prone to powdery mildew, though, so raise humidity with a humidifier or a tray of wet gravel rather than by misting.

Q.If the plant loses leaves in winter, has it died?

A.It's common for growth to slow and leaf count to decrease as temperatures drop, but this doesn't necessarily mean the plant has died. Keeping it warm and simply monitoring it often leads to renewed leaf growth once the weather warms again.
