Undulated Crypt (Cryptocoryne undulata) profile

Undulated Crypt (Cryptocoryne undulata) is from Sri Lanka, with a growth height of about 10-15cm and a leaf width of about 10CM, which is a common beautiful aquatic plant cultivated in aquariums. Leaf blade margin is wavy, dark red with twill.When the light is insufficient, the leaves appear green and the underground stem stretches vertically and "claws" in the water, so enough light is needed for its dark red leaves to show. Undulated Crypt likes old water and stable water quality, if in a short period of time water quality, lighting or water temperature changes sharply, the leaves are easy to rot. Propagation is carried out by side buds.

Morphological characteristics of Undulated Crypt

Undulated Crypt is from Sri Lanka, with a growth height of about 10-15cm and a leaf width of about 10CM, which is a common beautiful aquatic plant cultivated in aquariums. Leaf blade margin is wavy, dark red with twill. When the light is insufficient, the leaves turn green and the underground stem extends vertically, "branching" in the water. So it needs enough light to let its dark red leaves show through. Undulated Crypt like old water and stable water quality. If water quality, lighting or water temperature change rapidly in a short period of time, the leaves are prone to decay.

The ecological habits of Undulated Crypt

Undulated Crypt likes old water and stable water quality. If water quality, lighting or water temperature changes sharply in a short time, leaves are easy to rot.

How to grow and care for Undulated Crypt

Illumination: medium and strong illumination

Temperature: 22 to 28 ℃

Hardness: 2-12 DH

PH: 6.5 to 7.5

CO2: Need to be added

There are many types of prickly ash, including Undulated Crypt, bubble prickly ash, woker prickly ash, fountain prickly ash, etc.

Undulated Crypt has unique grass appearance and beautiful appearance, but its cultivation is daunting. The biggest difficulty in cultivation of Undulated Crypt is the ability of Undulated Crypt itself

1. Lighting

Get plenty of light.

2. Water quality 

The pH value of Undulated Crypt is from acid to weak acid. Generally, it is difficult to grow or even cause leaf dissolution if the pH value is higher than 7.0, and the hardness of water is low. Nitrates in water are low or even nonexistent.

3. Carbon dioxide

Adding the right amount of carbon dioxide is necessary.

4. Fertilizer

Undulated Crypt was mainly base fertilizer, with a small amount of liquid fertilizer added. When excessive liquid fertilizer was added, the density of the water would increase, and the Undulated Crypt itself would be out of balance, resulting in dehydration and wilting.

5. Temperature 

The planting temperature is about 22-28℃.

The function and use of Undulated Crypt

1. For water plant enthusiasts in China, Undulated Crypt is a kind of water plant with low universality. Its whole planting can express the impression of jungle.

2. Undulated Crypt itself is very sensitive to the change of water quality. The combination of prickly Pepper with landscape architecture can not only reflect the diversity of grass species, but also serve as an indicator of water quality.
