Identify my blechnum

Blechnum have basal leaves that form a rosette, and measure between 15 and 150 cm. The leaves are pinnate or carved, rarely whole. The soris - the fruits of the fern, glued to the backs of the fronds - are arranged in two rows, on each side of the veins.

Plant my blechnum

Plant preferably between September and the end of November or between March and the end of April, when the winter reserves are formed and the temperatures are not too low. Bury the roots a few centimeters so that the foliage is flush. Fill and pack well around the plant so as not to leave a pocket of air. Water copiously just after planting. If you are planting in a pot, use one whose volume corresponds to that of the plant, otherwise you will have to water it too often. You can use gravel at the bottom under mixture of soil, compost or compost for better drainage.

Water my blechnum

Water regularly in the first weeks. Try to avoid watering on sunny afternoons to minimize the amount of moisture lost to evaporation. If your plant is in a pot, check the top soil in the pot either by looking at it or touching it with your finger. In any case, if it hasn’t rained in a month, water !

Shelter my blechnum

If you have a potted blechnum, bring it inside before winter to a bright, unheated room.

Put outside my blechnum

Take out your blechnum after the last frost, and place it in the shade or in semi-shade.

Mulch my blechnum

Lay a thick mulch around your blechne in open soil before winter, because it can not stand the intense cold.
