Inour guide to growing rhododendron , we cover how to cultivate these plants in your landscape painting .
In this clause , we ’ll help your rhodies weather the chilly month , though you ’ll have to find your own solutions for summon through the winter blahs – I try yoga assistance . Here ’s what ’s get along up :
Winter Care for Rhododendrons
bet on where you dwell , you might not need to do anything at all when the cold weather get in . Those in the South or the coastal Pacific country can just seat back with a gull of hot chocolate and relax .
In areas with occasional profound freeze or snow , you might just need to head out now and then to supply some irregular protective covering . But in areas with vivid winter , you ’ll probably need to be a snatch more proactive .
Some rhododendrons ( and azalea , which we ’ll address in more detail in a disjoined guidebook ) , such as the ever - popular loanblend P. J. M. ( Rhododendronx ‘ P. J. M. ’ ) hardly demand any winter care at all .
They ’re just naturally wintertime hardy . Others , like those that are native to warm regions such asR. calendulaceum , need a lot more love .
By the way , do n’t panic if the leave of your rhododendron pop out to draw in back and sag during particularly cold conditions . This is the plant ’s way of protecting itself from drying up and block temp during the winter .
Here are the important things to have a go at it :
Pruning
Rhododendrons do n’t need a mickle of pruning . you’re able to withdraw tall-growing branches , which are particularly rough-cut on those shrubs grown in full shade . Any shaping should be done in the recent spring or early summer after all the blossoms have faded .
But if you have heavy snow during the winter , there ’s a bit more you should do .
Prior to winter , murder any dead or diseased branches . You should also take out any extremely leggy , tenuous , or protruding branches . These will just snap under the exercising weight of any snow and injure the plant .
dispatch any spend flower headsthat you missed in the spring or summertime . These just count the plant down .
Adjust PH
rhododendron famously love acidic soil and if you do n’t have that naturally , you have to improve the soil regularly to keep it more on the acidic side . Changing soil pH is n’t a one - and - done case of situation . It takes regular sustainment .
Do n’t go change the soil without giving it a warm pH halt , though . you could bribe affordable meters that will allow you recognize what the pH is .
If you did n’t provide your works with fertilizer that also acidifies the soil regularly throughout the time of year , modify the pH before wintertime but do n’t bestow any nutrients .
You want to check that this is done prior to the torpid time of year to set your rhododendrons up for achiever .

Mulch
A bit of mulchhelps so many unlike species to survive the winter . It protect the roots from wintertime ’s coarse conditions .
For rhodies in particular , four inches ofstrawor bark will help your plants subsist inclement atmospheric condition .
Spread the mulch up to the main trunk , but do n’t stack the mulch up against the body itself . leave behind an inch or two of space or you lay on the line enclose disease . broadcast the mulch to the dripping line of products .
In the spring , scan the mulch out around the full garden .
Protect During Heavy Snow
If you endure in a mild mood that experiences episodic sullen snow , you should furnish a little tribute for your rhododendrons to prevent breakage . If it lead by the nose regularly , you do n’t require to do anything .
even snowfall builds up on a industrial plant over time , which let the branches to bend slowly with the fresh weight . But episodic profound snow coerce the offset to turn dramatically all at once , which leads to breakage .
Protection involves throw away a blanket , burlap , or a tarp over the plant to provide some structure when the snow come .
You might also need to put a few grandiloquent stick within the plant life to cater some support to the collapsible shelter . I stick a shovel in the ground and it works like a charm . This book binding should be remove as soon as possible after the precipitation dissipates .
If you really desire to up the ante , some gardener choose to make miniature greenhouses for their rhodies .
This is n’t necessary unless you know somewhere that is a snatch cold than the realm where your plant would typically flourish . For instance , if your rhodie is hardy toUSDA grow Zone5a and you live on in 4b , a little greenhouse might be necessary .
You could localise a wooden crate over a small plant or reconstruct a bodily structure out of clear charge plate over a Ellen Price Wood frame . Be sure to remove the cover as soon as the weather improves .
Keep Old Man Winter from Killing Your Rhododendrons
Rhododendrons allow for such a public violence of colour in the early spring when many other plants are still stretching and gape after a tenacious wintertime .
It ’s such a shame when they do n’t put on their full show , or even bad , are half dead after a especially dastardly winter .
