If you live in a part of the country where frigid winter temperatures would damage or kill Encore Azaleas – no worries! You can still enjoy these wonderful shrubs by planting dwarf Encore Azaleas in pots and then overwintering them inside.
Here’s how to keep your Encores healthy while spending the winter indoors:
1. Plant your azalea in a good potting soil created for acid-loving plants.
A peat-based, soil-less potting mix is ideal.
2. Before moving indoors, check for spiders, spider mites and other bugs.
Wash the plant with an insecticidal soap solution. If you reuse the pot in which the plant has been growing all summer, remove the plant and wash the pot inside and out with a diluted bleach solution. Then rinse the pot thoroughly with fresh water before repotting.
3. Your pot should be large enough to easily accommodate the plant’s roots.
Be sure water can drain easily from the pot. Drill extra drainage holes in the bottom of the pot if necessary. Good drainage is essential for your plant’s health.
4. Put your potted Encore Azalea in a location that receives bright indirect light for at least six hours a day.
Indoor azaleas like cool air, ideally between 60-68° F. Protect your azalea from freezing drafts near exterior doors and icy windows. Also avoid hot, dry air coming from air vents.
5. Keep the soil consistently moist but never soggy.
If the leaves turn crispy brown or the azalea suffers from increased leaf drop, this is likely a sign the plant is not receiving enough moisture.
6. Increase the humidity around your plant.
Place your potted azalea on top of washed pebbles or gravel in a shallow tray filled with water. You may also use a room humidifier. Avoid direct misting of leaves, as this can promote fungal disorders and pests.
