Azaleas are not picky about their location. They like being exposed to sunlight, but should be kept out of direct sun. An indoor azalea does best at cool temperatures, which helps the blooms last longer. Azaleas are not discouraged by central heating or air conditioning, but it’s never a good idea to put plants right next to heaters.
Water and fertilizer
Don’t give them too much water, or too little. Whatever you do, don’t let them dry out. Water the Azalea immediately when it feels dry to the touch. Give more water when in bloom. Watering azaleas is sufficient but they also enjoy being dunked in a bucket of water, pot and all. Pull the azalea out when the bubbles stop and let it drain.
Does it need fertilizer? No, when your Azalea flowers, it has enough fertilizer in the soil. Easy-peasy. What’s more, Azaleas are not very susceptible to disease, so dressing is not necessary
Can azaleas rebloom?
Getting azaleas to rebloom is possible but it’s not easy. If you’re up for the challenge, make sure to remove the wilted blooms. Relocate the Ghent azalea to a cooler location with plenty of (sun)light. Water the plants on a regular basis to keep them from wilting.
After flowering, but never during, azaleas could use some fertilizer. When the weather heats up, around the 15th of May, plant out the azalea, pot and all, in your outdoor garden. Give plenty of water during the month of May. Take the plant back inside when temperatures are at risk of dropping below zero (usually around October). Relocate to a cool and well-lit location.
