Propagating your Maidenhair Fern

Propagation is the practice of taking a piece of existing plant material to create a new individual and expand a population. Growing Maidenhair Fern (Adiantum Aethiopicum) can be achieved through two popular methods known as spore and rhizome propagation.

Spore propagation involves dispersing the spores from the fern’s fronds into soil or compost, where they will germinate in time. To give them an early start, it is recommended that growers use a heated propagator at temperatures between 15-20°C (59-68°F).

The spores should then be provided with light but indirect sunlight, while being kept moist and well ventilated. It may take several weeks for visible progress to occur, so patience is key!

Is Maidenhair Fern poisonous?

Growing the Maidenhair Fern (Adiantum Aethiopicum) is a popular choice for many gardeners, but it’s important to understand that this plant is considered poisonous. Although typically not fatal for humans, ingesting any part of the Maidenhair Fern can cause nausea, vomiting and abdominal pain.

Pets are particularly vulnerable to the effects of this poisonous plant, so it’s essential to take precautions if you have animals in your home. Maidenhair Ferns contain calcium oxalate crystals which release histamine-like compounds when ingested or touched.

These toxins make contact with skin and mucous membranes and can cause burning sensations as well as swelling of the tongue and lips. As such, it’s best to wear gloves when handling this fern and keep children away from any part of an Adiantum Aethiopicum plant.
