It is difficult to maintain the black wood fern, and it has higher requirements for the growth environment. It is easy for the plant to grow poorly in the uncomfortable environment. It needs to grow in acidic soft water. It is difficult to grow in alkaline hard water, and it is prone to black spots on leaves and blackening of the whole leaves. It also has requirements for water temperature environment, and it is easy to blacken and rot in water with too high temperature. During maintenance, the water temperature should be kept between 24 and 26 degrees Celsius.
In addition, because of its special root system compared with other aquatic plants, it needs to be planted in a well-ventilated environment. Otherwise, it is easy to cause anoxia in the roots of plants, which eventually leads to root rot and plant death.
Black wood fern maintenance is slightly difficult. During maintenance, a suitable growth environment needs to be provided for the plants, the pH value of the water is adjusted to be between 5.8 and 7.0, and the hardness of the water is adjusted to be between 2 and 12, so that the water quality environment is kept in a slightly acidic soft water state, and the plants are prevented from blackening.
In addition, when planting, the plants can be tied to rocks or sunken wood by binding method to ensure that the roots of the plants can breathe normally. Do not plant it directly in sandy soil, otherwise it will easily cause plant death.
