养护难度

适合高级者

寿命

多年生水草

体型

茎长40～100厘米

适宜温度

24〜30℃

浇水

需要CO2添加、底床肥料和液体肥料

光照

需要强光最为重要。光照不足时茎会变弱而折断。

CO2与肥料

CO2添加能大幅加快生长。在营养底床基础上，还需施加微量元素、硝酸盐和磷酸盐。缺乏时叶色变暗，节间伸长。

水温与水质

适宜水温24～30℃。需要软水（碱度0～7°dKH），pH 5～6.8的偏酸性。

底床与附着

植入营养系底床。适合作为后景至中景的红色点缀。

修剪与繁殖

剪取顶端重新栽植最为简便。保留下方茎段，最上端的节点会萌发新芽。

注意事项

绿色卡博姆巴（芋头属）为不同种。水草不应丢弃在室外，防止逃逸到自然水体（海外曾有野生化成灾的案例）。

关于红叶芋头

Red Cabomba is a stem plant with finely dissected leaves that turn reddish-brown to wine-red under strong light. Distinct from green Cabomba caroliniana, it needs intense lighting and soft water, making it a pick for experienced aquascapers.

开始养护红叶芋头前需要了解的7件事

1. 1Placement and Light

   Red Cabomba develops its deepest reddish-brown to wine-red color under strong light. Plant it toward the middle to back of the tank, away from floating plants or taller stems that could shade it. If light is too weak, the color tends to fade toward green.

2. 2Water Quality and Softness

   Red Cabomba prefers soft water, and growth can slow noticeably in hard water. If your tap water is on the hard side, using softened or conditioned water helps keep the plant stable. Regular water changes also support consistent coloration.

3. 3Adding CO2

   Because red-colored aquatic plants photosynthesize actively, adding CO2 helps support steady growth and stable leaf color. It can still grow without CO2, but tends to fade or grow leggy more easily in that case. Pairing strong light with CO2 makes it easier to bring out the beauty of its whorled leaves.

4. 4Choosing Substrate

   Since it absorbs nutrients through roots along the stem, a nutrient-rich substrate helps support steady growth. It pairs well with soil-based substrates, which also help keep the water soft and slightly acidic.

5. 5Trimming and Replanting

   Since the stems can grow to roughly 40-100cm, regular trimming is needed to match your tank's height. Cut tops can be replanted as new stems, letting you propagate the plant while maintaining your layout. As lower leaves start to drop from long stems, trim and thin them out to keep the plant tidy.

6. 6Seasonal Care

   Growth tends to become unstable when water temperature swings widely, so try to keep it as steady as possible. Growth can slow during cooler periods, so avoid letting the water get too cold.

7. 7Choosing a Healthy Stem

   Look for stems that are firm, free of melting or dark discoloration, and show a vivid reddish-brown to wine-red color. Checking that the leaves form neat whorls of three at each node is also a good way to judge a healthy stem.

红叶芋头的常见问题

Q.How difficult is Red Cabomba to grow?

A.Red Cabomba is considered an advanced-level aquatic plant. It requires consistently strong light and soft water, so it's best attempted once you have some experience keeping aquatic plants.

Q.Is it a different plant from green Cabomba?

A.Yes, Red Cabomba is a different species from green Cabomba (Cabomba caroliniana). It can be distinguished by its leaves growing in whorls of three at each node.

Q.How large does it grow?

A.It's a perennial whose stems can grow to roughly 40-100cm in length. Trim it periodically to match the height of your tank.

Q.What's the key to keeping the red color vivid?

A.Strong lighting is essential for maintaining its color. Keeping the water soft and adding CO2 also helps the coloration stay more stable.

Q.Can it be propagated?

A.Yes, it can be propagated by cutting the stem tips and replanting them. Trimming back overgrown sections and reusing the cuttings as new stems is an easy way to maintain your layout.
