Your winter prep begins prematurely of the chilly season, you wish to cease fertilizing round mid to late summer season, relying in your area.
Your vegetation ought to have lengthy completed flowering and placing out new development by this level, so that they don’t want any further meals. You don’t wish to encourage your azalea to place out development when it must be hunkering down for the winter.
Just a few years in the past, I planted just a few new azaleas, and we had an unusually dry and sizzling summer season.
One was in a very good quantity of shade and acquired moisture from the irrigation system, whereas the opposite didn’t and it was in full solar.
That winter, we had a chronic freeze that actually challenged numerous my backyard specimes. The azalea that had been burdened all summer season died, whereas its close by pal survived simply wonderful.
The ethical of the story is that you simply shouldn’t underestimate the significance of protecting your vegetation wholesome all year long.
You must proceed to water each week or two main as much as the winter if fall in your space is sizzling and dry. Azaleas want a number of moisture to take up the vitamins they should survive by way of the chilly months.
Be certain the soil is good and moist earlier than the chilly units in. If there’s a freeze on the horizon, water as quickly as you already know it’s coming.
I’m not suggesting that you simply overwater and switch the bottom right into a soggy, mushy mess.
You wish to give the suitable quantity of moisture on your specific kind of azalea, however simply be certain that you retain doing so even because the winter approaches.
Add 4 to 6 inches of mulch from about an inch away from the stem to the drip line of the shrub.
The drip line is the world that extends to outmost components of the cover, the place the rain would run off and fall to the bottom. Any natural mulch is okay, so be at liberty to make use of your favourite wooden chip, well-rotted compost, or leaf litter.
In the event you reside in a chilly area, I choose to make use of complete, deciduous leaves as a result of they create warmth as they break down, including only a trace of heat to the soil that your vegetation will admire.
In case your mulch tends emigrate due to wind or critter visitors, use one thing heavy like wooden chips.
Lastly, in case your backyard tends to develop into a rabbit or deer buffet within the winter, shield the plant with some fencing.
A four-foot-tall barrier of hen wire subsequent to however not touching the foliage is often sufficient r to maintain hungry critters away.
In-Floor Azaleas
Past watering and mulch mentioned above, you don’t have to do a lot to guard your azaleas throughout typical climate. By typical, I imply the type of climate that your space experiences each winter.
However say, for instance, that you’ve an especially dry interval that’s uncommon on your area. In that case, get on the market and provides your vegetation some water to assist them make it by way of.
They gained’t want a ton of water since they’re no less than partially dormant, however simply make sure the soil doesn’t dry out fully.
On the opposite finish of the spectrum, you additionally have to be careful for very chilly climate.
In the event you sometimes have freezing, snowy, or windy winters, and your vegetation are used to it you don’t want to fret when that happens. Your plant is ready to adapt to the situations.
When a tough freeze happens, the leaves could look droopy, curled, and unhappy. Don’t fear, it is a protection mechanism and it’s completely regular. As a result of the bottom is frozen, coupled with drying winds, the shrub can’t take up moisture.
You’ll be able to assist to cut back or restrict the quantity of wilting and curling by spraying your vegetation with an anti-desiccant like Wilt-Pruf, obtainable by way of Amazon.
When temperatures drop to about 40°F, observe the producer’s instructions and spray the the foliage and branches completely.
You can even assist shield your plant by offering a display to dam drying winds. Something from a sheet of frost material affixed to a body to a seaside umbrella secured in place will do the job.
Lastly, don’t contact the plant. Any motion at this level will trigger the water contained in the stems to freeze and cease shifting.
An azalea in temperatures as little as 28°F can nonetheless transfer water all through the stems and leaves, however for those who have been to shake the leaves, possibly whereas attempting to take away snow, it could trigger the water to cease shifting. This results in drying out.
When the temperatures enhance, the leaves will perk again up. Don’t water your plant and don’t attempt to manually thaw it out utilizing Christmas lights or something like that. Simply let Mom Nature do her factor.
The exception to that is for those who don’t usually expertise laborious freezes and your shrub hasn’t had time to acclimate to colder situations. In that case, you’ll wish to present a bit of further assist by overlaying it in frost material or burlap.

If you wish to go away the material in place for an prolonged interval, you will need to construct a wooden or wire body to offer some assist.
Container Crops
While you develop azaleas in containers, the foundation system is much less insulated than it’s within the floor and so is extra inclined to freezing and thawing, which might harm vegetation.
My suggestion is that you simply deal with your plant as if you might be in a single Zone colder.
So, for those who reside in Zone 8, fake like your azalea is in Zone 7 and plan accordingly. Meaning you should purchase a range that may survive in Zone 7.
When chilly climate is on the horizon, shield your plant by wrapping the container in burlap or wool to offer an additional layer of insulation. You must also add just a few inches of mulch to the highest of the soil, however don’t let it contact the trunk.
When you’ve got excessive climate, you may cowl the plant with frost material or you may take it right into a protected space.
As with these rising within the floor, in case your azalea is acclimated to the standard situations of your space, you don’t have to do something, past water and mulch.

Rising your vegetation indoors all winter isn’t actually an choice. The one kind that may survive indoors are florist’s azaleas (Rhododendron simsii). All others want a sure variety of hours under 40°F to develop flower buds.
You’ll be able to actually transfer a container-grown specimen right into a storage, shed, or basement throughout an excessive climate occasion, however it wants to stay exterior for almost all of the time.

When the brand new foliage emerges, you may assess if there are any lifeless branches or stems. You can even see whether or not any of the brown buds survived. Generally, it’s simply the outer layers of the buds which might be impacted they usually’ll get better simply wonderful.
