The Iris ( EYE - ris ) genus is n’t the largest out there , have somewhere between 260 and 300 species , but it is a pretty complex one .
With six subgenus and many of those being further dissever , it can get a picayune complicated to discuss caring for irises in cosmopolitan .
However , one thing all irises have in common is that you could develop them in container , despite this being something of a horticulture secret . In general , whiskered irises do well in pots than other mixed bag .
Because there are a few limited rules regarding the care of potted irises , this choice might not seem at first to be executable .
However , once you make out the fundamental principle , grow potted irises can be moderately rewarding , and some iris can even bloom out of time of year as a result !
Potted Iris: How To Care For And Grow Potted Iris Plants?
A little redundant care is needed to allow for the appropriate amounts of sun , nutrient , and water for a potted iris .
to boot , winter care is slenderly different , as is the frequency it might call for to carve up the plant .
Know Your Iris!
Before getting begin , it can not be stressed enough that you need to sympathize the primary care pauperism of a particular flag before set about to pot it .
Some metal money , such as the yellow signal flag ( Iris pseudacorus ) , prefer surfactant grease condition , while many detest soggy soil .
Some irises will involve more light than others , and some need more prospering soil conditions .
By cognize any special needs , your iris plant has , you could align the follow selective information slightly to well become those needs .
For example , an iris that want very small water can be allowed to dry out to a deeper depth , while the aforementionedyellow flag iriswill ask to be water when the surface is dry .
Choosing A Pot
Unlike many more commonly potted plants , your choice for an sword lily need some planning forrader .
This is because most iris do n’t like to be disturb , so the less often you require to repot , the better .
Tallbearded iriswill need a sufficiently large container ; no less than 12″ inch in diameter is recommended .
Meanwhile , dwarf iris mixed bag , such as the reticulated iris ( Iris reticulata ) , will need a kitty around 6″ to 8″ inches in diameter .
A good rule of thumb is to count how wide your sword lily will belike be once it clumps and select a pot about the same size .
This will preclude the plant life from becoming rootbound before it ’s time to divide it .
ascertain the flock is well - draining , as water is more restricted in a container than the ground .
Ceramic or terra cotta peck can help forbid water holding while allow for a little extra insulant in winter .
However , just about any decent material will work , and it ’s not rare for growers to use large plastic pots or alloy tubs with drain mess to plant multiple irises together .
Well-Drained Soil
While it ’s easy enough tomake fleur-de-lis potting soilbased on the needs of a special plant , the general rule is for the undercoat to have a pH of 6.5 to 6.8 , with the latter being ideal .
To increase acidity , add a little peat moss a few calendar month prior .
However , it ’s usually best to purchase robust soil with in force drainage organic potting mix with the appropriate sourness . Add in some perlite to further improve drain .
Mix in a little extra organic compost for irises that need copious soil , while irises better suit for misfortunate soils can often use a less rich mix with a bit of common guts mix in .
When set up a pot , consider how much pee the works like .
For those who need higher-ranking drainage , consider frame a base layer of gravel in the bottom of the sens to make a buffer zone while the water drains .
A Note On Planting
While it ’s potential to plant more than one iris diaphragm in a pot , it ’s commonly best to give each their separate pot . It ’s especially true of rhizomatous irises , as they tend to diffuse out horizontally .
For bulbous iris diaphragm , you ’ll need to space each plant at least 6″ inches aside , although you should n’t plant more than three bulbs per container .
you may thin the young plant out or begin them in a nursery container before implant them into their lasting locoweed when growing from seed .
Plant rhizomes so that the very top is above soil point , as they take photograph to the elements to thrive . Bulbs should be engraft in a hole three times their stature .
Lighting And Hours Of Sunlight
Because irises do n’t care being move around , obtain a spot where they can get enough sunlight all year round or supplement natural light with grow lamp .
Most iris will need 6 to 8 hours of full Sunday per day .
If overwintering your iris , it will prefer a dark room , but if you ’re plan to hale blooms , it will call for good light throughout the wintertime .
A window with unobstructed southern exposure is perhaps the skilful alternative .
In some cause , growers prefer to target their container outdoors during the tender months and overwinter them at bottom to ensure the dependable possible firing .
Water
The soak - and - dry method is of the essence for a potted flora because the pee takes longer to debilitate out .
irrigate the grease juiceless 1″ to 2″ inches deep for most irises , but piddle when the surface is dry for mintage that prefer wetland .
Fertilizer
A balanced fluid houseplant fertilizer will forge wonders for your potted iris . Depending on the individual industrial plant , it may necessitate to line up how much and how often it is fed .
yellowed masthead and standardised species often do n’t involve feed at least once at the start of the growing season . In the fall , add some os meal to the potting grease .
Pay Attention To Winter Needs
Depending on the specie , iris may be winter bloomers or die back for the winter .
Consider the winter care requirements for when your plant ’s in a garden and adopt those rule for the potted plant .
If a plant life can be squeeze or have a winter bloomer , take advantage of the flexible indoor climate to provide the take illumination and temperatures .
observe that bulbous irises can be protect with a layer of mulch , but rhizomatous irises may become pathological if wholly cover .
When To Repot
At last , we amount to a more - or - less universal panorama .
Repot your iris every 3 to 5 years , using that time to divide the rhizome or light bulb and exchange the soil .
Be sure to implant rhizomes to the same profundity as they were before transplanting .
