Super - hardy genus Funka are a foliation favourite , especially for shady spots .
These deciduous perennial are valued for their enthralling foliage , as their foliage may be crinkly , bowl - shaped , cockle or ridged .
Though their colours let in a right copious ‘ leafy green ’ , they also let in creams and yellowness , and grayish - blue green .
Many are edged or border while others undergo colour change as the season march on .
If you go for bewitching foliage , have a fishy garden , also have intemperate soil , and like low - concern perennial , genus Hosta are made for you .
In this templet , we ’ve collaborated withSEVENhosta specialists , including :
“ Hostas are incredibly divers in size , leaf shape , colouration , and grain , ” says Barry .
“ Some Hostas grow in mounded shapes , while others are upright vase - work plants . genus Funka range in size from 5 - 125 atomic number 96 high .
“ Leaf shapes vary from lissome spear - shaped leaves to those that are more rounded . They can be green , yellowish , dispirited , or a combining of those colouration and may have variegated edge or expose diversification at their centre . ”

In their native Japan and the Far East , these plants are call Giboshi , but are more normally known as the Plantain Lily.1Hosta Collecting in Japan . ( n.d . ) . Hosta Library . Retrieved March 17 , 2023 , fromhttps://www.hostalibrary.org/articles/Japan.htm
They do share one property , though : almost all popular mixed bag are thud - forming and , therefore , gradually keep circularize .
The foliage interest group of these plants is astonishingly diverse and most nurseryman consider the flowers a side attractor or a bonus .
“ We love growing genus Funka because they provide colouring in the garden all season , from tardy Spring until the Autumn when they die down , ready to re-emerge the next year , ” says Sue .
For several weeks in summer , blossom , usually gong - shaped , are borne in clusters , ordinarily in shades of royal and white .
genus Hosta are vigorous , long - live plant , explains John Plant , the owner of Rewela hostas , with over 15 years of experience :
“ There are very few that provide the range of colour , and sizing of leaves than Hostas . They tender you at least 6 months of interest in the garden each yr .
“ They then go to sleep , but always arrive up again next twelvemonth without further cost or tutelage . ”
Once they ’re all prepare in favourable locations , they will need minimal criminal maintenance while making a plenteous takings of many years of top - snick ornamental foliage .
Choosing Types
“ I personally prefer plain - leave cultivar with interesting substance abuse , like Cutting Edge and Niagara Falls , ” say Melanie .
“ The leaf droop downwards on Niagara Falls and have a piecrust rippled security deposit .
“ I love natural - looking garden spaces rather than too much colour , so I have it off hostas that add to that type of environment rather than clash .
“ Although I can admire variegated hostas , I am less keen on the brightly motley cultivars as they can calculate rather false in a innate stage setting and look much intimately as specimens in container . ”
Despite Melanie ’s preference for unmixed cultivar , we have put togethersome of our favourite varieties of hostaswhich do include brilliant cultivars too .
How To Grow Hostas
“ adverse to democratic belief , hostas like more visible light and less water than most citizenry think , ” say Ollie Walker , the nursery manager at Sienna Hostas .
“ A very dark , wet billet in the garden is actually as risky as a dry and sunny spot . Ideally dappled shade or dawn / good afternoon sun in moist , free - draining soil is utter . ”
Hostas are classic subtlety garden plants and can be planted in beds or used forgarden borders .
However , it ’s unspoiled to keep in creative thinker that they boast an tremendous range in acme .
The modest varieties are perfect for front borders while the taller single are just as perfect for the stern and as backdrops .
The intermediate height varieties are great for intersperse between flowering plants in a bed or placing in a dedicated shrubbery corner .
Miniature salmagundi make for delicious edging and are just magnificent for rockeries .
All hostas plants are very amenable to being planted in pots and containers .
Though Hostas are problematic plants and can be planted at any clip of the year , I ’d urge plant them in spring or autumn .
Hosta are normally bought as potted plants or acquired as marginal - ascendent division from a thump , and it is in one of these forms that you would be planting a genus Hosta .
The planting kettle of fish should be about as deep as the rootball but twice its width .
Ensure that the flora is not root - bound ; if it is , spread out the roots .
commit the plant in the hole and backfill it quickly , insure that the territory tune is the same as it was in the tidy sum .
Pat down the soil all around and water well .
Hosta Plant Care
Hostas are ill-famed for being light to turn .
Once they are planted in the correct spot they will boom for years without any particular care .
accurate instructions on how to acquire these plants are given underneath .
In general , partial tint is very suitable for hostas and they even do quite well in full shade .
That say , the idealistic eccentric of light for these plant is dappled or filtered sunlight for a few hour a day , as David explains :
“ While some mean of them as ghost - sleep with , they are merely shade tolerant and perform good with some sun , the amount powerfully dependent upon their need for water and protection from the hot sun . ”
Sun - refinement preferences deviate by cultivar .
“ Hostas are ghost - kind industrial plant , but they still require some sunlight , the amount of sunshine largely depends on their color , which in general associate to the number of chloroplasts in the plant life , ” explains Barry .
“ Blue hostas seem blue because of a wax finishing on the leaf . If this wax finish is scratch off , or burn off by the sun , the leaf calculate green .
“ When caring for Funka with grim colouration , it is important to make out that too much lineal sunshine will burn off off the waxy coating on the foliage that makes the folio come along blue .
“ It is just to grow gamy hostas in a location where they get some former morning Dominicus follow by a day in the shade . ”
As a rule , the more xanthous the foliage , the more sunlight the works should get and the more bluish the foliage , the less sun it should get .
Hostas generally need a heavyish , rich soil says Robert Barlow , a hosta enthusiast from North Staffordshire Hostas .
“ Hostas like wet - retentive grime that are slightly acidulous . They do not , however , like to be submerged in urine for any length of time . ”
A sundry loam of sand , crank and Lucius DuBignon Clay till to about 15 atomic number 96 cryptic and amended generously with constituent compost or well - rotted organic manure will suit them perfectly .
These plants favor moist dirt .
If the soil has insufficient Lucius DuBignon Clay then some vermiculite should be added to the soil or a layer of organic mulch may be laid to increase wet retentivity .
somewhat acid to neutral soil pH works sound for these works .
“ The single most important affair about successfully growing Hostas is have it away that they love pee , ” says Barry .
“ Hosta require at least 2.5 cm of water per week to thrive . Hostas will survive with less water , but if you require your plants to expand , give them batch of it . ”
Although their water needs may partially be met by rain , watering will usually be required .
“ Do n’t give them a sparge of H2O daily , water once a week during the time of year and water well , ” suggest Melanie .
Hostas do not have any finicky temperature or humidity requirements , and any give variety should be perfectly comfortable with the temperature and humidity throughout the UK .
“ Hostas are excellent garden works that can grow in many garden conditions in climates with wintertime coldness , ” order David Teager .
“ Not merely unmarried - time of year perennial , they are most beautiful from the sentence they egress until the first killing freeze . ”
“ Although hardy in the UK climate , hosta leaves emerging in spring may get damaged by hoarfrost , ” adds Horticulturist Colin Skelly .
“ Protect by adding a layer or two of fleece if frost is foreshadow . ”
As long as hostas are root in rich , prolific territory , they do not involve fertilising .
A mulch of organic compost about once a year will be quite sufficient .
Otherwise , you may use anorganic balanced fertiliser , thin out as appropriate , once each leap .
“ Do n’t be tempted to overfeed your genus Hosta , ” sound out Melanie .
“ It may assist produce special foliage but often this is at the disbursal of the plant ’s characteristics . Seaweed extracts or tomato feed is effective a couple of fourth dimension a yr . ”
Hostas in containers should be fertilised more often to ensure attractive leaf .
For these , use a balanced liquid fertiliser about every four weeks during spring and summer .
“ I use a N liquid provender or pelleted chicken manure , ” say Robert , from North Staffordshire Hostas .
“ feast your hosta plant a maximum of 3 - 4 time a class from April . Do n’t feed your hostas after July . ”
Common Problems
Generally , hostas are blighter - resistant and disease - devoid plants .
Occasionally may they succumb tovine weevil , but this only commonly affect potted genus Hosta .
“ Vine weevils can sometimes be a problem , ” shares Sue Proctor .
“ Adult weevils feed on the edges of folio and the modest pass they cut out of folio edge are unmistakable .
“ I habituate vine weevil nematodes in September and April , centralise on those areas where there are attacks . ”
A more serious trouble that hostas might confront is Hosta Virus X ( HVX ) .
To escape this , David Teager suggest that you : check that to corrupt hostas from reputable dealers ( or share by well-educated champion ) , and closely observe and handle any young acquirement to charm any disease before it spreads .
alas , hostas are almost trusted to be targeted and chomp onby punch and snails .
Not only does this degrade the aesthetic appeal of the plants , slugs and snails sometimes destroy the leafage to such an extent that young , pocket-size , or imperfect plant life choke .
“ The most obvious problem , which everyone lights on , is slugs and snails , as there is nothing more infuriating than having your everlasting hosta leaves munched on , ” says Melanie .
Slugs have nocturnal wont ; they chew up plants in the dead of night and remain out of sight during the day .
Therefore , it is difficult to directly eliminate these plague .
Even if they were diurnal , poke are so gooey that you may not need to pick them or crush them !
“ Barriers and beer traps both work well for trapping slug and snail , but if your garden is overproduction , you first ask to scale down numbers by go out after dark with a blowtorch to discover , snatch and dispose of the critter , ” say Sue .
“ A squirt of household ammonia water diluted 1:10 with water will kill slugs almost instantly and is more humane than using a mite of salt . ”
Another tried - and - bank method is to put copper strip or copper tape around the plants .
A clout ’s own guck reacts with cop to give a modest cushion to the pest .
This method will only protect your plants but will not belt down the punch .
Another method is to apply a garlic dry wash , which is a method recommend by the raiser from both Rewela Hostas and Sienna Hostas .
“ A garlic wash is really easy to make , ” says Ollie .
“ Boil 2 full bulbs of ail in 2L of body of water until soft , then sieve out the bit to uncover your dressed ore .
“ Dilute 2 tablespoons of this , then water and spray over the top of your plants once a hebdomad . ”
“ My genus Funka used to get exhaust to bits until I was inaugurate to a garlic wash , ” divvy up Gardener Sally Flatman .
“ I used that religiously last year and now my hostas are completely exchange works ! ”
Alternatively , you could place purpose - make types of corner or crannies that slugs wish to get in or under cheeseparing to your chewed - up Hosta .
you could do so using flat rocks , pocket-size slabs , or wooden boards .
Get out in the other part of the dawn to look under them for the pest , and when look you’re able to get free of them easily .
