Greenhouse Rhododendron Simsii, commonly known as Azaleas are those beautiful, multicolored joys of spring, those bright spots in the grocery store or garden nursery when everything else is winter gray. Their bright beauty has caused many a gardener (and many non-gardeners) to ask, “Can you grow azalea indoors successfully?” The answer is, “Of course you can!”
Azaleas as houseplants do best at cooler temperatures, ideally around 60-65 F. (16-18 C.). Cooler temperatures will also help the blooms last longer. Keep them well lit, but out of the direct sun. Moisture should be your greatest concern in the care of indoor azaleas. Never allow your plant to dry out. While watering from the top may provide sufficient care, indoor azaleas enjoy the occasional dunk, pot and all, in a larger container of water. When the bubbles stop, pull it out, and let it drain. Whatever you do, don’t let these plants dry out. Keep them damp, not soggy, and don’t fertilize until flowering is complete. Apply a lime-free liquid fertilizer once every two weeks from late spring to early autumn.
