|Every time I plant an azalea it may last one season and then dies. What am I doing wrong.
|First make sure you are selecting a variety that is considered reliably winter hardy in your area. Plant in spring, not fall. Plant in a location with morning-only sun or bright dappled light all day and good protection from winter winds. Make sure the soil is suitable: humusy, organic, acidic. It must be evenly moist yet well drained, meaning not sopping wet/saturated and never dried out. Mulch year round with organic mulch, apply it in a flat layer two to three inches deep over the root area. Finally, make sure they are not planted too deep.
