What You’ll Learn
playfulness fact : fern grow on every continent except Antarctica – though there are fernfossilson Antarctica .
There are specie that grow in every USDA Hardiness Zone , from 1a to 13b . These plants have had centuries to adapt to even the rough environs .
That mean there are many species that have accommodate to the exact sorting of conditions we have in our homes , namely : warm , scurvy spark , and moderate humidity .
Cultivation and History
Ferns are plants in the botanical class Polypodiopsida , consist of about 10,500 existing mintage – and a set more that are now extinct .
scientist are n’t certain exactly how many species exist , and some estimate paint a picture that there could be 15,000 metal money out there .
These are truly ancient plants . While many of the species that we see around us develop relatively late on the timeline of major planet Earth , ferns were hang out with the dinosaurs and even well before that .
They first originate during the Devonian period , which began about 420 million years ago . This is the menstruation when Pisces really diversified , and the amphibians that would finally be the origin of all land mammals evolved .
Meanwhile , on land , the supercontinent comprise North America , Europe , and Greenland , and the southern land mass made up of innovative South America , Africa , India , Australia , and Antarctica , were brood in ferns .
This is , in part , thanks to the fact that the clime was warmer than it is today , which ferns typically prefer . These works really diversified during the Cretaceous time period .
Fast forward just a few hundred millennia , and through several bulk experimental extinction event , and you arrive in the modern earned run average with humans and ferns coexisting .
Growing ferns as houseplant became pop during the Victorian earned run average . People were obsessed with houseplants in cosmopolitan , and fern were high on that list . Pteridomania took grasp of England and the US around the 1840s and lasted for 50 years .
A lot of people chose to grow their plants in Wardian cases , the Victorian version of a terrarium , during this stop because the plants fail to thrive in the polluted , dry atmospheric condition of the city .
Not only was practically everyone mature the industrial plant in their homes and gardens , but the motif was plastered on anything and everything . masses bid the leave to display in their homes , and many believed that collect fern ameliorate their virility and mental health .
roll in the hay what we do about the impact of nature on human well - being , that last part might have some trueness to it , especially since collecting these plant life required people to get alfresco and explore the countryside .
Broadly speaking , most of the ferns we grow in our homes today are tropic species rather than those you ’ll retrieve in the wilderness of the northerly latitudes . That ’s because coinage from temperate zones do n’t thrive in the same consideration that you receive inside the modal household .
Many of these tropic fern are aerophyte , which means they grow sequester to other plants .
Fern Propagation
distribute ferns might seem intimidate as they are n’t like many other flora with their flush and source that you may pluck and sow in the soil .
But they ’re not so challenging – most can be reproduce through division , plantlets , stipe ( or bow ) cuttings , or by propagating the spores .
The spore appendage is lengthy and requires some especial equipment , but the others are n’t much different frompropagating any other houseplant . If you ’ve everdivided a plantthat was outgrowing its pot , then you ’re already conversant with the process .
The same start for stipe thinning , which are like to stem cuttings . While they ’re easy to accomplish , this method acting does n’t work on all species .
Regardless of which method appeals to you , our guide to propagating fernshas everything you need to have a go at it for winner .
How to Grow Ferns
Caring for a fern indoors depends on which type you are growing .
A staghorn fern ( Platyceriumspp . ) is passably happy indoors , but as I mentioned , many of our favorite garden varieties struggle at bottom .
Maidenhairs ( Adiantumspp . ) can originate indoors , but they are temperamental . Boston fern ( Nephrolepis exaltata ) , on the other hand , do well indoors .
In general , if a specie grows in coolheaded mood or if it has frilly , feathery foliage , it will be more difficult to originate as a houseplant . Species that are native to fond , tropic areas , which often have more solid fronds , do better . But there are elision .
Most metal money need bright , indirect light , consistently moist potting medium , and moderate humidity .
Most temperate climate fern require what we would call “ dappled ” sunlight , which is the kind of light you get underneath the canopy of a tree .
Indoors , that translates to a patch near a west- or south - facing windowpane cover in a bold curtain . Or peradventure you have an east- or south - facing window with a big evergreen tree right outside that block off the sun ’s rays .
Take some sentence to explore the finicky species that you ’re grow – or want to grow – and the conditions in its natural home ground . You might find that you have a species that likes to dry out out a bit and requires direct morning light .
loosely , you’re able to assume that a general potting mix will be o.k. .
Something like De La Tank ’s House Plant mixing , with its combining of compost , cocoanut coir , pumice stone , and natural fertiliser would be idealistic .
De La Tank ’s Houseplant Mix
Bring some homefrom Arbico Organicsin one- , eight- , or 16 - dry quart bags .
Container alternative is of import . You desire something that both continue moisture and is well - draining .
Terra cotta may look nice , but it dries out pretty rapidly . You ’re certainly welcome to use it , but be extra persevering aboutmonitoring the moisturelevel .
Better yet , choose glaze clay or stone . Whatever cloth you choose , the container needs to have drainage . If you find a muckle you love that lacks drain holes , that ’s ok . Just keep the plant in a fictile agriculturalist ’s pot and put it inside the decorative pot .
You could also drill pickle in the decorative stool , but if you are n’t experienced with the procedure , do n’t attempt it on a container that you care for .
The container should be at least a few inches wide-eyed than the be pot the industrial plant is grow in . Remember , the base of the flora is unlike than the width of the fronds . The frond tend to spread out much wide than the base .
You should also be sure the pot is grueling enough to hold the plant . You do n’t want to be scoop up dirt and humiliated fronds if the domestic dog get a second too excited and ping over your fern !
When you water , be certain to empty the catchment tray or container about 30 minute of arc after lacrimation . These plants ca n’t brook soggy base , with few exceptions .
Different species vary wildly in their H2O preference , but most need soil that is moist but not torpid . piddle when just the top of the soil dries out .
fertilise your plantsonce a month during the springiness and summertime with a modest , balanced food for thought .
A product with an NPK around 3 - 3 - 3 or 5 - 5 - 5 works well . Even well if you may find something higher in nitrogen than phosphorus and potassium .
For instance , Arber ’s Plant Food has an NPK of 3 - 2 - 1 and a elusive rosemary fragrance that smells much better than your typical fertilizer .

Growing Tips
Pruning and Maintenance
There ’s no need to prune ferns except to remove any jaundiced , discredited , bushed , or snuff it frond . Otherwise , the only maintenance you ’ll need to do is repotting or dividing the plants as they mature .
Many species do n’t bear in mind being a picayune root word bound , but they eventually require to move up to a larger corporation , or you require to divide them to provide more outer space .
Repotting and dividing also gives you the opportunity to replace the grime , which can become hydrophobic or consume .
The first stone’s throw is to remove the plant from the survive container and knock down out any supernumerary stain . Then , brush the soil away from the source . Loosen up the roots .
If you ’re upgrade the pot size , grade the plant into the new container and fill in around the roots with refreshed , clean potting soil . The plant life should be sitting about the same height that it was in the existing pot .
If you ’re dividing the plant , use a unclouded pair of scissors hold or pruners to cut through the roots and petiole to make two or more subdivision .
Replant one section in the old weed with fresh soil and either dispose of or give away the other segment , or institute it in its own container .
Fern Species to Select

Maidenhair
Maidenhair ferns add up from theAdiantumgenus , and the plant within this genus have different requirements .
For instance , western maidenhair ( A. aleuticum ) is aboriginal to westerly North America and grow in zone 3 to 8 . It ’s a challenge to grow indoors because it prefers a nerveless , dormant time of year and warm days mate with cool nights .

Managing Pests and Disease
Indoors , there are only a few thing to watch for on your fern . shell and spider mites are the most rough-cut pest you ’re likely to move into .
These pests both suck the sap out of the plant ’s leave of absence and stems . Both will have symptom like yellowing foliage , but spider mites will be go with by a fine webbing on the leaves and stems .
The okay webbing is a pretty good meter reading that your works has wanderer mites , while the presence of little oval ball , which are the scale leaf insects themselves , tell apart you that scale is present .
If you identify spider tinge , head to our guideto learn how to address them . If it ’s scale you ’re facing , natter this guideto avail you combat this plebeian pestilence .
When it comes to disease , root rot is the main cause for business organization . recall , these plants do n’t like abide piddle on the tooth root . Root bunkum has two cause .
It can either be contagion by pathogen in thePythiumgenus or an abiotic condition make by overwatering , essentially drowning the root by depriving them of oxygen . Pythiumpathogens need lots of moisture to survive , and contagion can be promoted by overwatering .
If you see drooping , yellowing , or embrown fronds , dumbfound your finger in the stain . Does it find any bed wetter than a well - wrung - out quick study ? If so , you ’re probably overwatering . Sometimes , the top of the stain will feel fine , but it will be swampy at the root , so it helps to feel down as deeply as you’re able to .
If you suspect root rot , tear the plant out of the container and dampen off all of the territory around the roots . Prune off any quaggy or blackened root with a clean pair of scissors , then spray the roots with copper fungicide .
Wipe the container clean and check that the drain hole is open and clear . Repot the plant in brisk , blank soil and be extra deliberate not to overwater in the future . You are emptying that catchment container 30 minute after lacrimation , right ?
Best Uses for Ferns
fern work both as specimen in a single muckle or in grouping .
A specimen in the center of a container palisade by trailing flora likepothosorphilodendronsmakes a remarkable addition to the family .
you’re able to also grow them in terrarium or , well yet , an antique Wardian case .
