Growing Boston fern indoors, care and placement

Having a fern indoors is not difficult, but there are a few things to keep in mind to ensure your nephrolepis is as healthy as possible.

Light

Boston ferns thrive best in indirect light. Place them in a bathroom with a window, a bright corner, or in a spot out of direct sunlight. Direct sunlight can burn the leaves, while too dark a location will cause them to lose their vigorous form. This fern can tolerate relatively low light conditions and is therefore suitable where other plants cannot stand.

Watering and humidity

Ferns often want even moisture and wet soil. This is where spear ferns differ, as they absolutely do not like to stand in wet soil. However, a severe drought can quickly cause the leaves to wilt or turn yellow. It is better to water a little and often, and feel free to shower the leaves if the air is dry. Humidity is the key to a healthy and large fern.

Soil and nutrition

Plant in airy, well-drained soil, preferably a mix for green plants, like our peat-free soil. During spring and summer you can give weak nutrition every other week. Repot every other year, especially if the roots start to fill the pot.

Boston fern in a pot outdoors, is that possible?

Yes, having a fern like sword fern in a pot outdoors works great during the summer months, as long as the location is shady or semi-shady. Bring the plant inside before the autumn frosts arrive, as Boston fern cannot tolerate cold.

Frequently asked questions about ferns and Boston fern

My Boston fern is losing leaves, what do I do?

Yellowing or drying leaves are usually caused by drought, dry air or too much sun. Cut off any damaged parts and adjust watering. Also keep an eye on the humidity, especially during the winter.

How do I make nephrolepsis grow bushy?

To make a fern plant grow denser, you can stimulate it by cutting away older shoots and giving the plant even access to light and water. A large fern also needs more space, so don't choose a pot that is too small.

Can you take cuttings or propagate Boston fern?

Boston fern spreads via small shoots from the base. When replanting, you can carefully divide the plant to get multiple plants. Look for new small leaves or rooted side shoots at the edge of the pot.

Types of nephrolepsis, are there different varieties?

There are several fern varieties, but Nephrolepis exaltata 'Duffy' is one of the most popular. It has slightly smaller, denser leaves and is particularly suitable as an indoor fern in smaller spaces.
