Container GrowingDivisionGrowing From SeedOverwinteringPruning
Cannas are deciduous perennials that are noted for their good stalks bearing racemes of brilliantly - colour flowers that pull up pollinators in droves .
Now in their native tropical and sub - tropical climes Cannas require no wintertime concern at all but it ’s a different matter in almost all of the UK .
These beauty are highly - suitable alien , having put down on British shores from their wacky and cheery homes in Central America and Equatorial America .
Therefore it is not surprising that they need to be care for in wintertime . After all , they are ‘ sturdy ’ only to H3 .
Caring for Cannas during winter in the UK will depend on whether you have mature them in open soil or in containers .
If you shack in the paring of land along the southern and easterly coast and your outside Cannas are grow in a sheltered spot , your task will be much wanton .
Overwintering will generally look on how and where you are develop yours – see all three option below –
1) Overwintering Potted Canna
Before autumn ’s first freeze or when the plant goes hibernating , do as follows :
Cut back the foliage and stalks as appropriate for Cannas .
Remember to desex cutting implement before using them .
Move the container indoors where the temperature will not dip below 12 ° 100 .
2) Overwintering Outdoor Plants (Zone H3 Or Warmer)
you’re able to impart Cannas outdoors in Zone H3 ( or warmer ) , especially if they have been site in a sheltered spot .
Give the plant a in effect watering so that the dirt is moisten to a depth of 10 - 12 cm .
lie a layer 8 - 10 curium deep of constitutive mulch around the plant .
Use a mulch made from leaf mould , husk , and such .
Lay it several cm by from the cornerstone of the works .
test to protect the ground from excessive rain , soaking , or puddling .
3) Overwintering Outdoor Plants (Zone H4 Or Colder)
Please see detailed instructionsin our Division guideexplaining how to thin out back and remove rhizome .
fetch the take rhizomes indoors to your workroom , shed , cellar , or such .
Gently clean the rootstalk with a soft cloth . If necessary , dampen the textile .
Lay the rhizomes on sheets of newspaper diffuse on a level surface in a dark , temperate room for two to three daylight so as to dry them out .
Turn them over after a daylight – the room temperature should be between 13 ° -18 ° C .
Coat or pack each rootstalk in vermiculite , otherwise in peat moss , and wrap it in a half - sheet of newspaper .
This will need to be done individually for each rhizome for better protection and storage .
Do this project withdryhands and do not grant any moistness to cower in .
How ? scatter a thin layer of vermiculite all over one closing of the half - sheet of paper . Gently push the rootstalk into the canister or container of vermiculite and roll it around , and thread it up covered in vermiculite . Put it on the stratum of vermiculite on the newspaper , and twine it , so that the vermiculite is lifted up with the newsprint as you wrap the rootstock .
Put the wrapped rootstock in an suitably - sized large but flattish composition board box seat .
Do not heap them and seek to leave some space between neighboring ace – result the boxful open .
Store the box in a cool , ironic and dark-skinned place , such as a shed ; however , the temperature should remain between 7 - 13 ° C .
This is where the rootstock should continue until springiness .
When you unpack them , we urge that you scrutinize each rootstock for wellness and viability .
