CANNA GUIDES
Container GrowingDivisionGrowing From SeedOverwinteringPruning
Cannas display a profusion of fan - shaped leave that are usually in rich tones of gullible but many varieties sport dramatic foliage in red and bronze shades – with some even flaunting variegated striped leaves .
They are irregularly shaped and have wavy , mess up petals .
For the most part , they are seen in warm , vivacious tone but refined white and easygoing yellowness are also available .
These plant usually grow to 1 - 1.5 m in height but can be tall if the right conditions are provide .
Can You Grow Canna Lily In Pots?
Yes you could !
In fact , if you are located in a region with a hardiness of H4 ( most of the UK ) or colder , then it will likely be to your advantage to do so .
That ’s because canna rhizomes must be overwintered indoors in cold parts of the country , and a tidy sum can simply be move as - is indoors .
Here is a canna I grew from seed and place on the windowsill of my sleeping room at place :
Living in Leeds , I found it highly advantageous to be able to move this to worthy clime during summertime and then winter , though it needed regular watering – especially in such a small pot .
It has prosper in a magnetic north - facing windowsill of my home in the colder months of the class – and grew much faster when pose outside in the summertime month .
I will transplant this into a much larger hatful next year and anticipate it to blossom for the first time .
Choosing Growing Pots
Cannas require large containers as they are big industrial plant – they grow to at least 1 m and 2 m improbable varieties are not uncommon .
Though small plenty are absolutely suitable for the relatively unusual gnome cannas , you will need 30 - 40L pots for full - size canna smorgasbord .
Besides size , the container has to be sturdy enough to accommodate the necessary amount of dirt and the size and weight of the works .
It must also be strong , so sturdy charge card or ceramic pots are better choices .
Whichever character of container you choose , it must have drain holes of sufficient size of it and routine because very good drainage is required .
Potting Compost For Canna
canna take well - draining , loosesoil that is rich and fertile with fiddling clayand that retains wet .
A mixed loam better with moxie , perlite , or both , and with ample constitutive compost or even some well - rotted manure , will be sodding for these plants .
Although these plant support many kind of soil , blossom will be affect in less fecund land .
Further amending the grease with vermiculite or set a thin bed of mulch on the open will retain wet , which is especially important for outdoor potted Cannas in the summer .
A somewhat acidic stain pH is idealistic , but not of the essence .
Planting Canna In Pots
Canna rootstalk should be plant when the filth temperature is 10 ° C or gamey .
Late spring to early summer will work exquisitely in most regions of the UK .
As a rule of thumb , rootstock should be planted about twice as deep as the rhizome is wide , which usually means a depth of 6 - 10 centimeter .
They should be planted horizontally with the eyes upwardly .
If the rhizome has any roots , you know which is the down side .
Cannas are sun - devotee by nature , so full sunlight is just about mandatory for these plants .
Initially , water meagrely just so that the soil becomes moist .
keep doing so until the rhizome send up stubble and leaves , increasing the amount of water thereafter .
As the plant matures , water it munificently so that the stain bide moist throughout .
You should set Cannas one to an appropriately - sized container .
They are big plant life and also uprise very quickly , so they need elbow room to develop their root organisation .
However , you could plant several cannas in a large planter , but they will need to be spaced fit in to their respective heights and spreads .
Most Canna kind should be spaced by 40 - 50 cm .
Potted Canna Care
These tropic works opt moist land and soil in container dries out quicker than that of a bed , so peculiar attention should be pay to tearing , especially in hot atmospheric condition .
The dirt should not be permit to dry out and remain teetotal as moist soil is preferred .
Fertilise these plants with a granular assure - release plant food in mid - spring or with a ready - to - pour liquid fertiliser once a calendar month before and during the inflorescence season .
prefer a high-pitched - potassium formulation .
Canna rhizomes multiply and occasional class is even more important for container - grown plant than those grow in the ground .
If rhizomes are allowed to keep multiply , they will choke one another and contend for the limited nutrients in container soil , and , as a result , industrial plant wellness and bloom will adversely be regard .
In most regions of the UK , cannas need wintertime protective cover .
If grown in a container , they can be strike indoors into a warmer location over the winter calendar month .
