Culture method of Dryopteris nigra

Black wood fern is a kind of pteridophyte with transparent green leaves. Many people often use it to make aquarium landscape when raising fish or turtles. What are the cultivation methods of black wood fern?

1. Water quality requirements

Dryopteris likes the water quality environment of acidic soft water, when it is in alkaline hard water environment, black spots will appear on the leaves or even turn black completely.

2. Matrix

Dryopteris Dryopteris is suitable for cultivation on a well-ventilated substrate, otherwise it is easy to suffocate the roots due to lack of oxygen so that the roots can not breathe normally, resulting in root rot. Therefore, in general, it can be bundled with fishing line and planted on sunken wood and rock. If you want to cultivate it close to the bottom sand, you can bury the lower part of the volcanic stone into the sand after binding it to the volcanic rock to ensure that the horizontal rhizome is exposed to the sand.

3. Temperature requirement

When cultivating Dryopteris under water, attention should be paid to controlling the water temperature between 20 and 28, otherwise the black leaves are easy to rot.

4. Fertilizer requirements

The demand for fertilizer is low, generally only a small amount of liquid fertilizer can be added.

5. Other management matters

The original leaves of Dryopteris fern will blacken and die due to the change of environment when it is cultured and transplanted under water. This is a normal phenomenon. Under the premise that the environment basically meets the requirements of the above culture, there is no need to deal with it, and under the condition that the environment is stable, new leaves will germinate in about 3 weeks, and the blackened leaves will be cut off after the new leaves are luxuriant.

Generally speaking, black wood fern is very easy to raise, as long as the substrate is found, the temperature is controlled at 20-28 degrees, and some liquid fertilizer is added appropriately.
