A pest, rather than fern identification. Tiny black mites are flourishing on the fronds of a fern wall I created earlier this year. Asplenium scolopendriums are the most heavily affected but they are also present on Pteris species. The leaves feel weak and a bit dried out. The bugs look smaller and legless compared to a black aphid.
Need I worry or will they disappear with the colder temperatures. The wall is pretty sheltered and next to the house so may never get frosted.
What’s the best treatment, if needed.

Hi – could you identify the fern shown in the three attached images. I saw it yesterday, growing amongst Hart’s Tongues and light bramble in a shaded area of a young woodland (mostly Hawthorn) on sloping ground in fairly deep (450mm at least), moist (not wet) soil – Fuller’s Earth type geology with limestone underlying. The Fern was about 250 – 300mm tall. The area is not readily accessible to the public.

Thanks

this fern is growing in some dead New Zealand sphagnum moss with a Cephalotus follicularis. do u know what it is? many thanks.

As in previous post.

Please could you help me with identification of this plant? I think that it came as a sporeling on a purchased plant. The three fronds are all from the same plant.

Hello I was wondering if you could help I would really like to know what this little fern is. Last year I litter picked a beer bottle from the moat around a medieval manor site next to where I live. I was about to put the bottle in the recycling when I spotted there was something growing in it. At first I thought it was just moss but when I managed to get it out there was a tiny fern too. It survived the removal from the bottle but has remained very small. The longest fond is about 2cm, so it has been quite difficult to photograph. I have looked at the back of the leaves but can’t see any markings and I am sorry the back of the leaf photos aren’t very good.

I have two self-sown Cyrtomium fortunei, 4-5 years old that appeared on my tufa rockery. Since being relocated 2 years ago to an established shady raised bed that is filled with enriched (multi-purpose compost) London soil they have produced sparsely bladed fronds with contorted pinnae.
Is this disease or am I growing up a rather ugly cultivar?

If disease, can it be treated, or would euthanasia be a better solution? If it’s a cultivar, does it have a name?
