Do Ferns have spore cases?
The growths on your fern are not from a fungus. They are fern spore cases and are not harmful to the plant. Unlike flowering plants, ferns reproduce by spores rather than seed. Spore cases (sporangia) are produced on the bottom side of the fronds; each case contains numerous spores.
What do you notice on the underside of fern leaves?
Spores. Recognizable ferns are the sexless second generation that produces spores. Individual spores are encased in structures called sporangia, which are the dots that appear on the underside of fern fronds. The sporangia have caps called indusia that contain the spores until they reach maturity.
What are the dots on the bottom of my fern?
These dots are called sori and enclose the spores. These stalks dry quite well and are often used in flower arrangements because of their attractive color. They are also an attractive winter focal point if left on the ferns.
What insect lays eggs on ferns?
Fern scale is a small insect, 1.5 to 2.5mm long, that lives out its life cycle on and around ferns. Fern scale eggs are brown and oval shaped, about 0.2mm long, and found in groups.
Do Ferns have eggs?
The eggs are housed or maintained in the gametophyte. And that dependence on water is why ferns are so often linked to wet habitats. If the sperm do manage to get to an egg, fertilisation occurs, and that is where the two, the sperm and egg come together.
What diseases do ferns get?

How do I know if my fern is healthy?
So make sure your fern is getting enough bright, filtered light to thrive. Otherwise, they will get yellow fronds. However, few ferns can withstand full midday sun and will quickly begin to turn brown. A room with north-facing or east-facing windows is a good choice.
How do you get rid of bugs on ferns?
Remove individual mealy bugs by dotting them with a cotton swab dipped in rubbing alcohol. A solution of 10 percent rubbing alcohol and 90 percent water can be sprayed directly onto the fern for heavier infestations of mealy bugs.
What do Fern mites look like?
Fronds might begin dying. Spider mites appear as very tiny moving specks to those who even see them; symptoms are often noticed before the mites are discovered. You might see webbing and stippling on the leaves where the mites have sucked out juices. Leaves or new shoots might die.
Does soapy water kill ferns?
Soaps and detergents are toxic to plants. A strong solution of soapy water sprayed onto foliage can disintegrate the leaves’ waxy coating, resulting in water loss and the eventual dehydration death of the plant.
How do you kill scale insects?
To get rid of scale insects prune and dispose of infested branches, twigs and leaves. When scale numbers are low they may be rubbed or picked off of plants by hand. Dabbing individual pests with an alcohol-soaked cotton swab or neem-based leaf shine will also work when infestations are light.
