Fern

The irrigation of the Fern

The Fern belongs to the Dryopteridaceae family, classified as Pteridophyta that is a plant with leaves, stem, roots and vascular system. The Maori natives call it Koru (circle) and attribute it to the symbolism of peace, virility and growth, also considering it a metaphor for the circle of life. We can find the stylized Fern in countless of their tattoos and artistic works. It is among the most popular species as a houseplant, thanks to its ability to humidify the air and purify it from any toxic substances. The Fern needs humidity and cannot stand water stagnation. During the summer, water it two / three times a week, in winter water it only when the earth is absolutely dry. Spray the leaves daily.

Plant cultivation and care


The male fern (Dryopteris filix-mas) is certainly more widespread than the female fern. It grows in the woods at the foot of the oaks, which is why the Greeks called it “Drys (Oak) Pteris (Fern)”. The soil where you grow your Fern should be moist but not stagnant. It prefers acidic, sandy soils rich in nutrients. Perfect would be a soil formed by sand and peat increased by the addition of sphagnum and chopped bark. The Fern should be planted in spring by taking a sprig of plant that also includes the roots and placing it in the ground. As for the repotting, to always be carried out in spring, it is advisable to do it only when you notice the roots protrude from the pot, just transfer it once a year from the old container to a slightly larger one.

How and when to fertilize


The Fern does not bloom and does not produce fruits and / or seeds, it proliferates by producing spores that are carried by the winds and, once deposited on the ground, make it possible for the sprout to be born. The fern that grows in pots must be fertilized every 15/20 days with a liquid fertilizer rich in nutrients that has a good ratio between macroelements and microelements, in this way the plant will develop more harmoniously and will be more resistant. This specific fertilizer will strengthen and make the plant luxuriant thanks to the nitrogen content, it will strengthen its structure thanks to the potassium and the humus present in its formulation will make the leaves even more green and brilliant. Fertilization for plants growing outside must be supplemented, every 4/5 months, with a slow-release granular fertilizer.

Exposure, diseases and remedies


The Fern should be placed in cool and shady but bright places, it should never be exposed directly to sunlight. The ideal habitat would be the woodland, protected by the semi-darkness generated by large trees with large leaves. The Fern hardly gets sick, in the unfortunate case very few can be the causes. In case of Chlorosis the leaves obviously turn yellow, this is due to the poor absorption of iron. First we add iron sulphate to the irrigation water and, as soon as possible, we lower the pH of the soil by increasing the amount of peat present. If the plant is covered with dark spots we are in the presence of Cochineal, rub it with a cotton swab soaked in alcohol or a sponge and neutral soap, then rinse thoroughly.
