波浪莎草（Cryptocoryne undulata）

波浪莎草（Cryptocoryne undulata）的基本資料

栽培難度

適合新手

壽命

多年生植物。通過子株不斷增殖

體型

高度15～30 cm（寬葉型）。因環境而異

適宜溫度

22〜26℃

澆水

無肥料、無CO2添加也能生長

光照強度

即使光線較弱也能生長。光線越強，植株越矮小越緊湊。

CO2和肥料

無需添加CO2。使用含養分的底床可加快生長速度。

水溫和水質

最適水溫為22～26℃。在pH 5～8的範圍內可以生長。

底床和種植

植株易形成緊湊的圓形，應小株分植，株間間隔數厘米。

修剪和繁殖

將母株周邊的子株剪離種植，生根後生長相對較快。

注意事項

換盆、光照或水質的急劇變化容易引發「隱水草軟葉症」（葉片溶解）。只要根莖存活，新葉就會長出，因此不要拔起，耐心等待。水草不要棄置於野外，也不要讓其逃逸到水槽外。

關於波浪莎草（Cryptocoryne undulata）

Cryptocoryne undulata, a Sri Lankan aquatic plant with wavy brown leaves and occasional marbling, is an easy, beginner-friendly perennial that grows well without fertilizer or strong light and spreads via offshoots.

開始照料波浪莎草（Cryptocoryne undulata）前需要了解的7件事

1. 1Thrives in Low Light

   Cryptocoryne undulata doesn't need strong lighting, making it a good fit for corners or the back of a tank where other plants would struggle. Under brighter light, its color deepens and it grows lower and denser.

2. 2Sensitive to Water Changes

   Sudden shifts in water conditions, especially right after planting, can cause "crypt melt," where leaves dissolve. As long as the roots stay healthy, new leaves usually regrow once conditions stabilize.

3. 3Prefers Nutrient-Rich Substrate

   It grows fine without fertilizer, but a nutrient-rich substrate or root tabs encourage stronger rooting and steadier growth. Bury the roots firmly in the substrate when planting.

4. 4Avoid Frequent Replanting

   This plant settles in and grows best once its roots are established, so it's better to replant as rarely as possible. Trim overgrown or damaged leaves at the base to keep the plant healthy.

5. 5Spreads via Offshoots

   As a perennial, it sends out runners that produce new plantlets over time. Once a clump gets crowded, you can separate the offshoots and replant them elsewhere to start new colonies.

6. 6Shape Shifts with Conditions

   In lower light and nutrients, leaves tend to grow larger and more elongated; with more light and nutrients, the plant grows shorter and denser. The same variety can look noticeably different from tank to tank.

7. 7Choose Firm, Healthy Leaves

   When selecting a plant, look for clearly defined wavy leaf margins with little discoloration or melting. Marbling patterns vary between individuals, so comparing a few is part of the fun.

波浪莎草（Cryptocoryne undulata）的常見問題

Q.Is this a good plant for beginners?

A.Yes, Cryptocoryne undulata is considered a beginner-friendly aquatic plant. It grows well without fertilizer or strong lighting, so you can start with minimal equipment.

Q.The leaves melted right after planting — is it dying?

A.This is likely "crypt melt," which can happen right after planting or when water conditions shift suddenly. As long as the roots are alive, new leaves usually appear once the water stabilizes, so give it some time.

Q.How does it propagate?

A.As a perennial, it naturally spreads by sending out runners that produce new plantlets. Once an offshoot has grown enough, you can separate it from the parent plant and replant it elsewhere to expand your colony.

Q.Does it need CO2 injection or strong lighting?

A.No, neither is required. This plant is known for thriving without fertilizer or strong light, though giving it more light and nutrients will make it grow shorter and denser.

Q.How does the broad-leaf triploid form differ?

A.Alongside the standard form, a broad-leafed triploid variety of Cryptocoryne undulata is also available. Care requirements are basically the same, but the leaves have a different visual impression.
