Adiantum capillus veneris
The Adiantum capillus veneris is a plant widespread in Europe and Asia which is used as a houseplant and is grown outdoors in areas with mild climate. It grows spontaneously in the Mediterranean regions, near the springs, in the cracks of the walls and at the entrance to the caves. The light green fronds are composed of numerous triangular leaves, carried by black petioles. This species is commonly called maidenhair. It has a height of 10-40 cm with creeping rhizome. This plant is also found in mythology. It was in fact consecrated to Pluto for its predilection for dark and lightless places. The adiantum is also linked to the nymphs. Legend has it that the nymph Driope fell in love with a young man and took him to an underwater cave, right next to the adiantum plant.
The maidenhair fowl favors shady locations; then place it at a window where the sun doesn't shine. In any case, it is advisable that the beams do not directly hit the plant. The temperature must never be below 13 degrees. Fears drafts and domestic heating. As for watering and environmental humidity, the soil must always be moist without water stagnation. Spray the leaves often, preferably with rainwater. During the winter, reduce irrigation to avoid the formation of stagnation. The water to be used should not be too cold but rather warm.
The ideal soil for the plant is porous and very permeable: a soil formed by leaves and peat is ideal for adiantum capillus. During the spring season, it is possible to administer fertilizer, leaving about 15 days between one fertilization and another.
Maidenhair can be reproduced by spores but it is very difficult. The simplest system is by division of the rhizomes in spring. The rhizomes are planted in pots with a mixture of soil, peat and sand in equal parts. The pots are kept in a protected place in the shade and in a humid atmosphere. It is repotted in spring when the roots come out of the pot. The substrate necessary to carry out the multiplication of our seedlings must contain peat, soil and sand in similar proportions. As seen previously, the pots containing the plant must be placed in a shaded area, away from direct sunlight; the soil should always be kept very moist and the temperature should be between 15 and 17 degrees.
Pests and diseases:
The Adiantum capillus veneris is attacked by the red spider and the root cochineal. If the leaves become dry you need to water further and vaporize the leaves with water, if they fade the plant suffers from an excess of brightness, if they curl up it means that the plant suffers from the cold.
Even scale insects can hit the plant and appear on the lower part of the foliage. To avoid the problem, respect the cultivation requirements of the plant by cultivating it in cool and humid environments. In case of attack of the cochineal, rub the affected parts with a wad soaked in water or alcohol or buy specific pesticide products.
