常春藤

常春藤的基本数据

养护难度

适合新手

寿命

多年生（常绿蔓生植物）

体型

室外可攀爬至6～24m或更高的高度。盆栽中可通过修剪蔓茎进行控制。

浇水

生长期适量使用观叶植物专用肥料。

光照与放置位置

从全日照到深荫都能适应。室内放置在明亮处叶片生长较好。

浇水

盆土表面干燥后浇水。过湿易导致根腐和茎腐。

温度·越冬

耐寒性强，室外也能越冬。室内冬季管理也不困难。

用土·换盆

使用排水良好的用土。室外地植可能蔓延至墙壁、排水沟和周围树木而难以清除，因此盆栽或容器栽培较为安全。

繁殖方法

可通过蔓茎扦插轻松繁殖。但带品种名的植株中也有植物品种保护法登记品种，繁殖后销售或转让前需确认是否为登记品种。

病害虫·注意事项

注意蚜虫、粉虱、红蜘蛛、介壳虫以及叶斑病和白粉病。叶片含有皂苷，犬和猫食用会导致呕吐、腹痛、流涎和腹泻。树液可能引起皮肤接触性皮炎，修剪时应戴手套。

关于常春藤

English Ivy (Hedera helix) is a hardy evergreen vine that climbs with aerial roots, prized for its wide variety of leaf shapes and variegation. Easy for beginners and popular in hanging baskets.

开始养护常春藤前需要了解的7件事

1. 1Bright, Indirect Light

   Direct, intense sun can scorch the leaves, so a bright spot with indirect light, such as near a sheer-curtained window, works best. Variegated cultivars need slightly brighter light than solid green types, or their patterning tends to fade.

2. 2Water When Topsoil Dries

   Water thoroughly once the top of the soil feels dry, letting excess drain freely from the pot. Always empty the saucer afterward, since sitting in water can lead to root rot.

3. 3Well-Draining Soil

   English Ivy prefers well-draining soil, so mixing perlite or pumice into a standard houseplant potting mix helps prevent soggy roots. It dislikes both waterlogging and extreme dryness, so aim for a mix that balances drainage with moisture retention.

4. 4Repot Every 1-2 Years

   Because it grows vigorously and fills its pot quickly, repot into a slightly larger container roughly every one to two years. Early spring through early summer, when temperatures are stable, is the best time to repot.

5. 5Winter Care Indoors

   It's fairly cold-tolerant, but keep it away from cold drafts and dry heating vents in winter. Growth slows during the colder months, so cut back on watering and check that the soil has dried before watering again。

6. 6Choosing a Healthy Plant

   Leaf shape and variegation vary enormously between cultivars, so it helps to look at the actual foliage before choosing a plant you like. Pick one with healthy, undamaged leaves and vines that look vigorous all the way to the tips.

7. 7Toxic to Dogs and Cats

   English Ivy is considered toxic to dogs and cats, so place it on a high shelf or in a hanging basket out of pets' reach. Households with small children should also make sure the leaves aren't put in the mouth.

常春藤的常见问题

Q.Is English Ivy easy for beginners?

A.Yes, English Ivy is a tough, adaptable plant that's considered one of the easier houseplants to grow. Give it bright indirect light and well-draining soil, and it should thrive without much fuss.

Q.How big does English Ivy get?

A.Outdoors, it's a vigorous climber that uses its aerial roots to scale walls and trees to considerable heights. In a pot, regular pruning keeps it at whatever size suits your space.

Q.Is it safe to keep around pets?

A.English Ivy is considered toxic to dogs and cats. It's best displayed somewhere pets can't reach, such as a hanging basket or a high shelf, rather than at floor level.

Q.Why are there so many different leaf types?

A.English Ivy has been bred into an enormous number of cultivars, resulting in wide variation in leaf shape and variegation. You'll find rounded leaves, deeply lobed leaves, and forms with white or gold variegation, so there's plenty of choice.

Q.What should I do if the vines get too long?

A.Simply trim the vines back to whatever length keeps the plant looking balanced. Cuttings root easily in water, so you can propagate new plants from the trimmings if you'd like.
