How fast do Australian tree ferns grow?
A well-grown tree fern is a fast-growing plant, and will likely outgrow its space within a few years. The trunk of the Australian tree fern starts out as a low, wide clump and spreads as much as six feet in a year before growing upward into a single slender trunk covered in glossy ginger-brown hairs.
How long does it take for ferns to grow full size?
But, it typically takes five to ten years for a fern to reach full maturity after planting, when the full height and spread of the plant will be achieved. Tree ferns are the slowest growing ferns, and can continue to gain height for decades.
How long have ferns been around?
While ferns first evolved in the Devonian, they became one of the most dominant groups of plants on the planet during the Carboniferous (299-369 mya). Growing alongside the giant tree lycophytes (e.g., Lepidodendron) in vast swamps, ferns thrived and diversified for several million years.
What are the characteristics of a tree fern?
A tree fern’s unusual trunk consists of a thin stem surrounded by thick, fibrous roots. The fronds on many tree ferns remain green throughout the year. In a few species, they turn brown and hang around the top of the trunk, much like palm tree leaves. Growing conditions for tree ferns include moist, humus-rich soil.

How fast do dicksonia tree ferns grow?
Dicksonia antarctica averaged 33 (± 13)mm/year, increasing by 6mm/yr/m. Growth rates dependent on initial height were unexpected and we discuss possible reasons for this finding.
Do ferns get bigger every year?
With this in mind, you should know that most ferns are considered to be slow-growing. This means that it takes quite some time for them to reach full maturity. What is this? Some types of ferns can take several years to reach their full size, but some might be able to reach full size quicker than that.
Do tree ferns multiply?
Like all ferns, tree ferns reproduce by means of spores formed on the undersides of the fronds.
How quickly do Australian tree ferns grow?
Tree ferns are generally slow growing, at rates of just 25-50 millimetres height increase per year. This means the tall individuals you might spot in a mature forest may be several centuries old.
How fast do ferns multiply?
Creeping rhizomes grow from several inches to one foot per year and form a large colony. Clumping rhizomes are slow growing and form a tight clump. Knowing whether a fern is a creeper or a clumper is an important fact to take account when incorporating these plants into your landscape.
How long does it take for tree fern fronds to grow?
Individual fiddleheads (each newly emerging frond) can unfurl and expand within days. But, it typically takes five to ten years for a fern to reach full maturity after planting, when the full height and spread of the plant will be achieved.
Do tree ferns have deep roots?
It does seem incredible that a “tree trunk” will root and grow, however tree ferns are quite unlike other woody stemmed plants in that a large part of the root system is actually in the stem. They will produce roots into the ground but they are never that extensive.
Can you cut a tree fern in half?
This plant should be dug up and moved - it will not survive if it's cut in half. The rough tree fern can be recognised by prickly hairs growing at the base of the fronds and the large round leaf scars on the trunk.
Do tree ferns need a lot of water?
Tree ferns do not respond well to drying out, so it's important for you to water them year-round. In particular, the driest and coldest months of winter and the warmest months of summer will require diligent watering. Be sure to spray the trunk and foliage with water to prevent the plant from drying out.
What is the fastest growing tree fern?

How often should you water a tree fern?
The potted fern needs daily watering as the warm air circulating around the elevated fern will forever dry your fern. The best method is a dripper in the crown. Also, after 4-5 years, if still in the pot, it will be root bound, you will need to remove it.
Do tree ferns prefer sun or shade?
shadeTree ferns are happiest growing in shade, but they can grow in sun as long as they are very well watered. They dislike exposed or windy positions.
Do ferns get bigger?
Some are giant tree-like plants, while others rarely grow above one inch in height. Most like shady conditions, but a few grow best in nearly full sun. Some like dry soil, while most need to be kept constantly moist. However, there are some common things to know if you want to grow ferns in your garden or home.
Do ferns grow back every year?
Ferns plants in the ground can be left as is the entire winter. The fronds will protect the plant's center crown, where new growth will emerge in the spring. Ferns are a hardy perennial plant that will grow back each year. Many gardeners bring potted ferns indoors to continue growing during the cold weather season.
What month do ferns grow back?
Both deciduous and evergreen ferns experience new growth in the spring. If you cut away old deciduous fern fronds down in the late autumn and old evergreen fronds at the end of winter, new fiddleheads, or crosiers, will emerge in the center of the plant in the spring and early summer.
Will ferns grow back if cut?
Ferns do grow back after cutting, but the new growth will emerge from the rhizome below the soil. This means you should cut any damaged or discolored foliage down to the crown at the base of the plant to stimulate new growth.
What is a Tree Fern?
Tree ferns are true ferns. Like other ferns, they never flower or produce seeds. They reproduce from spores that grow on the undersides of the fronds or from offsets.
What is an Australian tree fern?
Image by ilviaggiatore. Australian tree ferns add tropical appeal to your garden. They look especially nice growing beside a pond where they create the atmosphere of an oasis in the garden. These unusual plants have a thick, straight, woolly trunk topped with large, frilly fronds.
How to grow offsets?
You can also pot up the offsets that grow at the base of mature trees. Remove them carefully and plant them in a large pot. Bury the base just deep enough to hold the plant upright.
Can you grow tree ferns indoors?
In areas that get lots of frost, grow tree fern in containers that you can bring indoors for winter.
Can ferns grow in full sun?
Planting Tree Ferns. Growing conditions for tree ferns include moist, humus-rich soil. Most prefer partial shade but a few can take full sun. The species vary on their climate requirements, with some needing a frost-free environment while others can tolerate a light to medium frost.
Do ferns need humidity?
They need a climate with high humidity to keep the fronds and trunk from drying out. Tree ferns are available as containerized plants or as lengths of trunk. Transplant containerized plants at the same depth as in their original contained. Plant lengths of trunk just deep enough to keep them stable and upright.
How many inches does a tree fern grow?
One of the other main selling points for the tree ferns was that they only grow up to 1 inch per year which is perfect for a small ‘yarden’ like ours.
What is a tree fern?
Description from the Royal Horticultural Society – ‘Tree ferns are slow-growing architectural plants with spreading fronds above a thick trunk. They make striking plants for a sheltered, shady garden.’
How often should I water ferns?
Water the crown of the fern (which is the centre of the plant – the point where the fronds grow) and the trunk daily for six months after planting, and then keep it moist after that, particularly in unsheltered, sunny spots like ours. Never allow them to dry out. I water mine daily from early spring until late summer unless it has rained that day. Remember, you cannot over water them so it wont hurt to give them some more if you’re ever unsure – another rhyme, I’m on fire in this blog post.
Do tree ferns like wind?
Another thing that I’ve noticed is that tree ferns do not like their leaves being knocked about in the wind. We’ve placed ours next to the pergola so it’s been pretty unavoidable for them to suffer the odd blustery day and get a bit damaged by the posts as a result – especially since the leaf span is much wider this year. It’s just something to consider when you’re planning you’re garden. You might want to allow them a little bit more space where possible so that this doesn’t happen.
Can you overwater ferns?
Until you get around to planting them, ensure that you keep the trunk and the root ball nice and soaked in water. The great thing about tree ferns is you CANNOT overwater them, so don’t be shy and they won’t go dry. Ooooh, I like that…
Can you spray fern leaves in hot weather?
We would water the leaves daily to try and stop this from happening but this spring the penny finally dropped. I learned that spraying or misting house plants that sit in the window or in direct sunlight is not a good idea in hot weather as the leaves will get scorched.
Do ferns survive winter?
This is probably the most high maintenance part of owning tree ferns, but don’t let it put you off as honestly, it doesn’t take long and it’ll give your ferns the best chance of surviving the winter months. I did have a few people on Instagram slip into my DM’s accusing me of being “extra” and claiming that they don’t bother doing this at all, and, that their trees have been absolutely fine. I personally will continue to do this though as you just never know when a cold snap might come out of nowhere and freeze up your fronds – shudder.
How many living ferns are there?
Today, ferns are the second-most diverse group of vascular plants on Earth, outnumbered only by flowering plants. With around 10,500 living species (PPG 1), ferns outnumber the remaining non-flowering vascular plants (the lycophytes and gymnosperms) by a factor of 4 to 1.
How do ferns grow?
An entire leaf is called a frond, while further subdivisions are referred to as pinnae (first division), which grow along the main stem (called a rachis in ferns), and pinnules (subsequent divisions). The portion of the rachis without pinnae is referred to as the stipe (petiole), which attaches directly to the rhizome. Most fern fronds also have circinate vernation, in which the new growth is tightly coiled in a fractal spiral, which gradually unfurls as the leaf develops, protecting the meristem. This curling forms the familiar fiddlehead at the tip of new fronds. Ferns reproduce by spores, which are generally produced on the bottom (abaxial side) of leaves by specialized structures called sporangia. Sporangia can develop in clusters called sori, which can be circular (Figure 3), in distinct rows, or may even cover the entire underside of a leaf ( acrostichoid sori) and are sometimes protected by an overhanging structure called an indusium. Other species have a sterile/fertile frond dimorphy, in which spores are produced on only certain leaves and not on others.
How many species of ferns are there in the world?
The leptosporangiates contain the bulk of fern diversity, comprised of some 10,323 species, grouped into 44 families (PPG 1). Most leptosporangiate ferns, as well as all eusporangiates, are homosporous, meaning that each species produces spores of only one size. The aquatic ferns in the order Salviniales are the only exception to this rule, having heterosporous spores. In this condition, a single plant produces both small microspores, which develop male gametophytes, and a few much larger megaspores, which develop into endosporic female gametophytes. Whereas the gametophytes of most species will break open the spore casing upon germination, becoming independent and photosynthetic, the female gametophytes of heterosporous species are retained within the megaspore and are dependent on stored lipids and carbohydrates for nutrition. It’s likely that the retention of the female gametophyte in a heterosporous lineage of plants led to the evolution of the first seeds.
What are the topics covered in the fern section?
There are separate sections that cover topics ranging from fern morphology, phylogenetic relationships, and the fern lifecycle, along with the important role gametophytes play in the biology of ferns.
What are the two groups of ferns?
Broadly speaking, ferns can be divided into two groups, the eusporangiates and leptosporangiates, with most of the diversity occurring in the latter. These terms refer to how sporangia develop and mature. In eusporangiates, a given sporangium develops ...
How do sporangia develop?
In eusporangiates, a given sporangium develops from multiple initial cells on the surface of stems or leaves and consists of several cell layers in the early stages of development. Each sporangium can go on to produce several hundred spores.
What is the name of the leaf that grows along the stem of a fern?
An entire leaf is called a frond, while further subdivisions are referred to as pinnae (first division), which grow along the main stem (called a rachis in ferns), and pinnules (subsequent divisions). The portion of the rachis without pinnae is referred to as the stipe (petiole), which attaches directly to the rhizome.
How long does it take for a tree fern to grow?
The trunk of the Australian tree fern starts out as a low, wide clump and spreads as much as six feet in a year before growing upward into a single slender trunk covered in glossy, ginger-brown hairs.
How tall does a fern grow?
Typically, when we think of ferns, we picture plants such as painted ferns ( Athyrium niponicum), which achieve a mature height of just 18 inches. But in its native habitat of Australia, it can grow up to 25 feet or more.
How much sun does an Australian tree fern need?
Although Australian tree ferns are shade-loving plants in general, they can also thrive in partial sun or full sun locations where they get over six hours of light a day. Keep in mind, the more direct light the plant receives, the more likely it is that you'll need to increase your watering cadence.
Where do Australian tree ferns grow?
Australian Tree Fern Care. Australian tree ferns thrive in mid-elevation tropical environments, where they can sometimes be found growing in great, prehistoric forests swathed in tepid mist. The key to growing a healthy Australian tree fern is to provide it with ample humidity and consistency.
What temperature do Australian tree ferns like?
Australian tree ferns like a consistently warm and humid environment, with temperatures ranging from 65 to 80 degrees Fahrenheit. Australian tree ferns do not acclimate well to rapid changes in humidity or temperature, which can result in browning fronds.
Where can I find Australian tree ferns?
They're mostly grown as large, potted ornamentals in the United States and, when they are grown outdoors, are found mainly in public gardens and arboretums in tropical or semi-tropical zones. The plant has also naturalized itself in Hawaii, where it's regarded as invasive due to its fast growth and prolific self-propagation.
Is Tasmanian tree fern related to New Zealand tree fern?
The New Zealand or Tasmanian tree fern is closely related, but the species is actually Dicksonia antarctica, and it tends to have a narrower crown than the Australian tree fern (but has similar growth requirements).
How big is a tree fern?
Plant size. 6m height. 5m spread. Tree ferns are not actually trees, but with their tall ‘trunks’ and dramatic crown of fronds, they do look very tree-like. The trunk is actually a mat of fibrous aerial roots that need to be kept moist.
What is the name of the evergreen tree fern?
Dicksonia fibrosa – an evergreen tree fern that grows to 6m, with dark green, fronds up to 2m long. Cyathea australis – these evergreen tree ferns are slightly more tender and may lose their fronds in colder areas.
Can ferns be propagated?
Like all ferns, tree ferns can be propagated by spores, but being such slow-growing plants, it’s a very long-term project.
Is a tree fern hardy?
It’s classed as half hardy but will grow in the UK and tolerate quite cold temperatures. Tree ferns are very slow growing and work particularly well in urban spaces, where they look good against hard surfaces and look particularly striking in shady courtyards.
Can ferns grow in containers?
Tree ferns can be grown in borders or containers and need a damp, shady, sheltered spot, out of direct sunlight and neutral to acid soil. They grow well in boggy conditions near water too.
Do you water ferns?
It’s important to water your tree fern regularly, making sure the crown and the trunk are kept moist . The fronds may get battered and unsightly over the season, and older fronds will brown and die. However, you can use these old fronds to wrap over the crown to protect it from frost in winter.
