Indoor Care Guide for String of Hearts (Ceropegia woodii)
Location: Toronto, Canada
String of Hearts is a semi-succulent trailing plant native to South Africa, known for its delicate heart-shaped leaves and long cascading vines.
1) Light Requirements
Prefers bright, indirect light with some gentle direct sunlight.
Best placed near a south- or west-facing window. If summer sun is too strong, provide some shade.
Insufficient light can lead to leggy growth—long, weak stems with widely spaced leaves.
In winter, when daylight is limited, consider using a grow light to supplement light.
2) Temperature & Humidity
Ideal temperature: 18-25°C (64-77°F).
Minimum tolerated temperature: 10°C (50°F)—keep away from cold drafts or heating vents.
Toronto’s indoor air is very dry in winter—use a humidity tray (pebble tray with water) to slightly increase moisture levels around the plant.
3) Watering
Drought-tolerant—water only when the soil is completely dry.
In Toronto, watering every 1-2 weeks is usually sufficient, but check the soil first—insert a finger into the soil, and if it feels dry, it’s time to water.
Overwatering can cause root rot, so ensure good drainage.
4) Soil & Repotting
Requires well-draining soil.
A good mix includes potting soil, perlite, and coarse sand in a 2:1:1 ratio.
Repot every 2-3 years or when roots become crowded.
5) Fertilizing
Feed once a month with a balanced liquid fertilizer.
Recommended fertilizer NPK ratio: 20-20-20 or 10-15-10.
6) Pruning & Propagation
Prune to maintain a compact shape and encourage new growth.
Easy to propagate:
Place stem cuttings with nodes in moist soil or water—they will root easily.
The plant produces bead-like aerial tubers on the vines—bury them in soil to grow new plants.
7) Common Issues & Solutions
Yellow leaves: Overwatering—let soil dry completely before watering again.
Leggy growth (thin, sparse stems, wide leaf spacing): Not enough light—move to a brighter location.
Wrinkled leaves: Underwatering—water when soil is completely dry.
Root rot: Too much moisture or poor drainage—use a well-draining soil mix and allow the soil to dry between waterings.
8) Additional Notes
Fast-growing under ideal conditions—vines can reach up to 12 feet (3.6 meters).
Pet-friendly—non-toxic to cats and dogs.
Avoid low-light areas and excessive humidity to prevent weak growth and root rot.
爱之蔓的室内养护方法
坐标：加拿大多伦多
爱之蔓（String of Hearts, Ceropegia woodii），是原产南非的半多肉植物，有精致的心形叶片，细长的悬垂藤蔓。
1）光照：
喜欢明亮的散射光和少量直射阳光，
可以摆放在朝南或朝西的窗口旁，当夏天阳光过于猛烈时，需要让植物避开直射光线。
如果光照不足，会造成徒长，叶片间距边长，叶片细小等问题。
在冬天阴天日子持续，需要使用植物生长灯补充光照。
2）温度和湿度：
理想的生长温度是18-25°C，最低耐受温度是10°C，不能放在冷风口和暖气口附近。
多伦多冬天室内空气异常干燥，可以把花盆放在一个放有石子和水的托盘上，用这个方法增加湿度。
3）浇水
耐旱能力强，等盆土干透了再浇水。
在多伦多，每1到2周浇水一次，温度和湿度都会影响盆土变干的速度，用手指摸盆土表面，感觉不到水汽了就可以浇水。
浇水过多会导致烂根。
4）土壤和换盆：
使用排水良好的多肉土，可以用营养土、珍珠岩和河沙按2:1:1配土。
每2到3年，或者根系长满花盆时，需要换盆。
5）施肥
每月施肥一次，使用营养均衡的液体肥，建议氮磷钾比例20-20-20或者10-15-10。
6）修剪和繁殖
为了保持良好的造型，并刺激长新的枝条，把过长的、弱小的枝条修剪掉。
繁殖很容易，取带有节点的茎段埋到湿润的土壤，或者放在水里，都会繁殖出新芽，茎蔓上长出珠状的气生块茎，埋到土里也会长出新植物。
7）常见问题：
黄叶：浇水太多，需要等土壤干透再浇水
徒长（茎叶稀疏、瘦弱、叶距变大）：缺乏光照，需要摆放到有明亮光照的位置。
叶片发皱：浇水不足，盆土过干。
烂根：湿度过大，排水不良。
8）补充内容：
当生长条件适宜时，它的生长速度是很快的，最长能达12英尺（3.6米）。
对宠物无毒无害，适合养宠物的家庭。
避免摆放在光照不足，或者湿度过大的位置，这会引起生长不良或者烂根。
