The autumn fern Dryopteris erythrosora originally comes from China and Japan. The species designation erythrosora refers to the red (erythros) spore heaps (sora) on this fern. The Dutch name autumn fern has nothing to do with autumn as a season, but with the leaf color of the young leaves. That is bronze to red. You need a little patience, because this fern only comes to the surface in May. He keeps his leaves in mild winters. The name of the fern family Dryopteris comes from the Greek words 'drys' (oak) and 'pteris' (fern). This refers to their original location in the oak forests in the northern hemisphere. This fern is one of the species richest with many species that are fun for the garden.
For this Dryopteris erythrosora , it is important to simulate the situation at the original sites (oak forests) as closely as possible. The soil must therefore be humus rich . Because oak forests are generally lighter, these ferns can tolerate quite a bit of light, but they are best placed in a shady spot. They do hate wind and drought. Cut these ferns in March or April. Earlier it can provide frost damage to the new shoots. Later on you make it difficult for yourself because you have to cut between the new leaves. Mulch in the autumn with humus rich soil, so the fern gets food and the less hardy species have a little extra protection. Because the autumn fern only rises above ground in May, it is best to wait until April to cut it off.
