How to grow black wood fern?

1. Water quality

Dryopteris Dryopteris is an aquatic grass, likes to live in neutral to weakly acidic flowing waters, and grows very slowly in alkaline water.

The root system of Dryopteris Dryopteris is usually only suitable for cultivation on a well-ventilated substrate, otherwise it is very easy to die due to lack of oxygen, which will directly lead to root rot.

3. Planting

Under the same water quality and cultivation conditions, the black wood fern planted on sunken wood and rock and directly planted can improve the black wood fern needed for water grass landscaping, and the ventilation of sand and gravel layer should also be improved. The sand gravel with larger particles is selected for planting black wood fern, and the sand gravel gap is large enough to make the water layer convection with the water in the sand gravel, so as to send sufficient water-soluble oxygen into the sand layer for the normal breathing of the root system of the black wood fern, and it can make the black wood fern grow and develop normally.

4. Fertilizer application

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

At the initial stage of planting, Dryopteris fern will have an adaptation period of 2-3 months, so it usually maintains its original state, but it does not grow, and there is no need for special treatment at this time. It will grow naturally after it adapts to the growth environment, but the growth rate will be relatively slow.
