If you ’re in the UK and you have a genus Cordyline , the winter care you give your plant depends on the hardihood of the variety , the neighborhood you go in and the plant life ’s age .

Even the hardiest of Cordyline , most of which are small Tree , are only hardy to H3 , which means they should not be subject to extended temperatures of more than a few degrees ( Anders Celsius ) below freezing .

Depending on your area in the UK , the larger , semi - hardy genus Cordyline may be grown in receptive primer .

This is potential if the temperature dips just a little below 0 ° C now and then in your region .

However , for smaller , more tender varieties , it wo n’t be potential to keep these alive over wintertime here in the UK , so these will need to be grown in containers and moved indoors during the cold month of the year .

No matter which type of genus Cordyline you have and whether it is a container plant or growing in exposed ground , you’re able to take various measures to handle for it during winter :

These measure are explained in more depth below .

1) Bring Tender Varieties Indoors

bid potted Cordyline , with a hardiness number below H3 , may be preserve outside in summertime when the weather condition is warmer .

However , before the first hoar , they should be brought indoors .

Indeed , this stone’s throw should be taken if you anticipate even a few days of free burning temperature below 10 ° C .

2) Find A Suitable Spot

Even though you may make for your Cordyline indoors for the winter , these fairly finicky plant should not be placed in an inapplicable spot .

They will do better in a daub with normal way temperature and will be perfectly content if the spot is a little tea cozy , but undue temperature fluctuations should be nullify .

Furthermore , these industrial plant should not be placed near a venthole , be it an line - conditioning volcano or a heating one , or where they may suffer chilly draft .

3) Transplant Outdoor-Grown Types

Provided you live in a comparatively temperate part of the rural area , a semi - hardy genus Cordyline may be transpose in assailable ground .

For the plant to survive wintertime after wintertime in the UK , you necessitate to get a few variable star right in the first position .

First , the sort should have a hardiness rating of H3 or better .

Transplant only after the industrial plant is 3 or more geezerhood previous in mid to late spring .

Finally , the plant should be sited in a sheltered spot which drains well .

It should enjoy full sunshine but can get by with some partial shade if the facial expression is not Union - facing .

4) Provide Care For Outdoor Varieties

Before the first frost and the Second Coming of Christ of winter rain , send a 10 cm stratum of mulch around the industrial plant , allow for a few centimetres around the independent stem .

A leafage , straw , hay , orwood chip mulchis a estimable option .

Cordylines must be protected from the soggy solid ground especially in wintertime , as these conditions can prove fatal .

If heavy or elongated cascade are anticipated , rest a sheet of charge plate or tarpaulin around the base of the plant life , angled somewhat with bricks or rocks underneath , so that rainwater runs off and aside from the plant .

These industrial plant need to be wellprotected from Robert Lee Frost , snow , freezing rainwater and frigid blasts .

When this case of weather condition is potential , wrap the principal stem from the ground and also as much of the lower foliage as you may shroud .

Horticultural fleece is good , but burlap , dismiss or an old blanket will do .

Do not pull up stakes these wrappings on any longer than necessary and surely not for Clarence Shepard Day Jr. at a stretch , as the industrial plant will not be able to breathe and may take up to rot .

As soon as you see a meek sunny mean solar day , remove the wrap .

enclose the plant again in the evening and , if the keep abreast day is another pleasant one , remove the wrappings again .

“ Any leave outside the wrappings will take to be knocked to dislodge any coke that accumulates on them , ” says Horticultural Lecturer Peter Lickorish .

What Not To Do

Do not fertilise these plant at all from mid - autumn to early spring or snip them in any way during autumn and winter .

Whether your sugar palms are indoor plant or open - earth ones , water them only now and then during winter to hydrate them .

Simply control that the dirt and the root do not dry out wholly or continue dry unendingly .

“ Cold and fuddled weather , fuse , is deadly , ” says Peter .

“ If planting Cordylines outdoors , check that they are planted no deep than their original gage layer and exhaustively fork the ground first , to check good drainage .

“ Consider take in a camber in borders , so that territory slopes gently to the edge , such as where it fulfill a lawn .

“ This ensures that rain does not spend a penny in the delimitation .

“ The more brightly coloured the leaves , generally the more protection it will need .

“ If foliage should go brown , leave this in place until well into leap , to protect and isolate the lower parts of the works . ”
