But if you ’re growing it in Zones 4 to 7 , with fair low wintertime temperature below 10 ° F , the plant will die if you do n’t bring it indoors in winter .
In these cooler raise zona , opt to develop your plant in containers so you’re able to transport them readily when cold weather condition is on the means .
It is potential to set the bush directly in the soil in your garden or landscape painting and then dig them up to overwinter , but I do n’t recommend it .
When you ’re gardening in a region where oleander ca n’t hold wintry conditions , plant it in a plot of land or plot will demand far more effort when it ’s fourth dimension to move the plant , versus growing it in a container to begin with .
All that digging and add robs this flora of one of its best trait , as it ’s typically very easy to care for . Once the prominent mixture exceed five or six ft improbable , you ’ll have a battle on your hands to bring them out of the ground to move into protected quarters .
get up , we ’ll go over the recommended steps for protect oleander bush from the cold in geographical zone 4 to 7 . First , a few password about safety .
Precautions for Indoor Oleander Care
While being able to move such a pretty shrub indoors to survive rough winters might sound worthy , only do so if it wo n’t potentially endanger anyone living in the household with accidental toxic condition .
All parts of theN. oleanderplant can cause gastric or inwardness distraint , or even a fatal chemical reaction , if ingested by a soul or pet .

So verify to wear garden gloves to protect your hands while you take steps to protect the shrub from cold temperature . And if you ’ll be carry larger specimens in your arms , check that to fag out prospicient sleeves .
Pre-Planning
This is n’t one of those horticulture experiences where you might late realize a industrial plant will be threatened by a freeze and race out with canvas and rock candy to attempt to cover it at the last minute .
grow oleander throughout a rough winter expect preplanning in these expanse :
Know Your Weather Patterns
You ’ll first need to get conversant with your domain ’s USDA Hardiness Zone , so you ’ll cognize whether this plant life can grow there as a perennial .
I ’ll duplicate this of import message : If you live on in Zones 8 to 11 , oleander will grow happily in your garden as a perennial , planted outdoors year - round .
But if you ’re gardening in Zones 4 to 7 , you ’ll need to design to overwinter the plants indoors .
Also , make a notein your horticulture journalof your expanse ’s average first frost date . While oleander can outlive snow and even a concentrated frost , you ’ll aim to have it indoors well ahead of temperature dips below that critical 10 ° fluorine Saint Mark .
Pick the Right Size Plant
You ’ll also want to select an appropriate motley to maturate .
Ideally , you ’ll elect to plant a dwarf mixture that will contact three or four feet grandiloquent , max . That will make it simpler to line up a container for it and to move and repot the plant as postulate .
I ’ve seen beautiful large varieties of oleander cultivate to develop as single - luggage compartment trees in containers though , so you do n’t needfully have to limit your ambitions if you have the place and the strength to bring home the bacon the winter care these plants involve .
Also , consider reside the container on a rolling cart . If it ’s easy to move the shrub indoors , you ’ll be more potential to complete the job in a seasonable manner , with requirements in line with that minimal maintenance feature these bush are known for .

Choose a Suitable Container
ensure the pot you take has drainage holes and provides the plant with room to get .
For your sake , not the plant ’s , it ’s also helpful to secure a mint made of lightweight material . But call back that tipping over may become an takings with magniloquent specimen .
If it ’s big enough to admit a four - metrical foot bush , a stiff or ceramic pot will press quite a bit !
Propagate Some Backups
If you ’re a fleck of a pessimist like I am , part of pre - planning involves propagating a few surplus starts from thinning before you guarantee the steps to overwinter your main specimen .
That agency , you ’ll have backups available if the shrub does n’t get along well despite your good efforts .
If it does just fine – and it should ! – you ’ll have extra newbie flora to expand your keeping or share with fellow gardener .
Plan ahead to take the cuttings in early spring , before the plants get down to flower .
Then propagate new shrublet by following thedirections in our pathfinder to oleander care .
Prune Ahead of Time
If you ’re contrive to cut the tips to shape your shrubs a act , verify to do that in late summer or early autumn .
This will allow enough meter for the cut finish to harden off ahead of wintry conditions – and forwards of the move indoors .
Make the Necessary Moves
When should you move container - mature rose bay indoors to overwinter ?
Keep in mind that you ’re trying to avoid prolonged hard halt , and to skip the freeze out - thawing cycles that can damage your plants .
At the same time , oleanders really are n’t mean to be grown at heart over a long menstruum of time , so you require to minimize their fourth dimension spent indoors as much as potential .
A skilful via media is to bring them inside when winter temperatures begin to dip to 20 ° degree Fahrenheit . container may be return to a protected outside area as soon as temperatures are consistently above 40 ° F in springiness .
beforehand of the move , be sure to wash the outside of the container with soapy water and rinse them off , so you do n’t lend any pests or pathogen into the family with them .
Also examine your plants for any plague , and give the leaf a spraywith the hoseto dislodge any unwanted hitchhiker .
indoors , they want cool temperatures of around 40 ° F and bright light . A spot near a sunny window in anunheated greenhouse , shed , or garage is idealistic .
For most growing in Zones 4 to 7 though , the good idea is to keep the plant life in an unwarmed room where you could keep an center on them – as long as this does n’t bring them into field where positron emission tomography or unsuspicious humans might require to gnaw on the toxic plants .
Once your plant is privileged , jump the fertiliser . Growth lay off in the wintertime when oleander is dormant .
Water needs will be reduce at this time as well . Do give your plant some supplemental weewee , but only once the grime has become dry a few inches down in the pot .
A grime moisture meteris extremely handy here . It will tell you when the soil has become dry while also helping you to forefend overwatering .
When temperatures rise above 40 ° atomic number 9 once more , give it prison term to get acclimate to the brighter lights and cooler temp alfresco , harden it off with an additional 30 minute to an hour of pic each day over the course of a workweek or two until it can move back to its outdoor place full - time .
Keep an eye on the weather forecast , and convey it back indoors if a cold snap is imminent .
