  • There are a range of physical movements involved with ferns, from more active planting activities to regular watering
  • Ferns are fascinating to look at in the garden. That could be watching the gentle unfurling of the fronds in spring, or looking at the intricate patterns on the underside of a frond
  • For those with social anxiety, you may feel a kinship for this lovely plant that grows happily on the edge of things, not needing to be centre of attention

If you think ferns look like relics from an ancient time, that's because they have existed on Earth for around 300 million years. Ferns were around before the dinosaurs!

Ferns have enjoyed periods of great popularity. In the mid-19th Century Victorian England, fern fever ('pteridomania') took over. The fern motif was used to decorate many items, from wallpaper to pottery and clothing.

Today, the interest in ferns may no longer be a national obsession. But ferns are still fantastic plants to grow in the garden, found readily in garden centres and online.

Fern fact

The ‘silver tree fern’ is significant within New Zealand culture. It can be seen emblazoned on the All Blacks rugby top as well as on national coins.

Where to plant ferns in the garden

Most ferns you can purchase for your garden are naturally woodland plants. This means their favourite condition to grow in is somewhere with moist soil that is shady, or gets some dappled sun.

Not all ferns are shade lovers. Always check the specific growing suggestions for an individual fern species before deciding where to plant it.

You can plant ferns in the ground or in containers. If growing in a container, again check the sun requirements for that fern - you might need to keep your container somewhere reasonably cool and shady.

Ferns are also popular as indoor plants. Varieties that will do well indoors - such as boston fern or asparagus fern - will generally be available in the houseplant section of garden centres or online retailers.

In this guide, we concentrate on ferns to grow outdoors.

Types of fern

There are over 10,000 known species of fern. Some of the most popular types grown in gardens include:

  • Maidenhair fern (adiantum)- although often grown as an indoor plant, there are some tough varieties that will grow well in the garden. Very distinctive
  • Dryopteris - there are lots of varieties of dryopteris, many of which are brilliant in a shady spot in the garden.
  • Royal fern (Osmunda regalis) - the largest of all native British ferns, growing up to 2 metres in height
  • Hart's tongue fern - a native, evergreen variety. The long, leathery fronds are sword (or tongue!) like, which makes them a good contrast with more delicate fern varieties
  • Tree fern - For some added drama in the garden, tree ferns are amazing plants. The soft tree fern, Dicksonia antarctica is very popular. What looks like a trunk is actually covered in above-ground roots. They can reach 5 metres in height.

Fern fact

Ferns are unique because they do not produce flowers or seeds. Instead, they have spores that dot the underside of the fronds. Have a look and enjoy the endless fascination of plants!

Ferns are available to buy and can be planted for much of the year. Spring and autumn are particularly good seasons, when the ground is not too dry.

Dig a hole big enough for your plant. Carefully remove it from its pot, position in the hole and back-fill with soil. Try to have the crown (where the stems meet the rootball) just above the ground.

Watering

Ferns like a lot of water, but don't over water or they could experience rot. Ferns are often in shady spots, so dry out less quickly than plants in the sun. Try to water at the base of the plant and not directly on the fronds.

Pruning

It's personal choice how much you feel like pruning your ferns. You could remove any dead and damaged fronds to make way for fresh growth and improve circulation to the plant.

In late winter or early spring, you could cut all fronds down to ground level. This will leave you with a head of dormant growth.

There are several ways to propagate ferns, including:

  • Collecting and sowing spores
  • Diving plants
  • Through leaf cuttings

You are likely to have the greatest chance of success through dividing plants. Fern roots are not too delicate. Spring is the ideal time to do this.

To divide your plant, dig the whole thing up. Using a knive, divide the rootball up into two - or even four - separate parts. Make sure each part has some leaves on it.

Then, simply dig holes and plant each part in its new location - or, put some up and give them away if its more than you need.

Fun fern idea

As ferns have such prehistoric beauty, younger children could spark their imagination by placing toy dinosaurs among your ferns and creating their own Jurassic world.
