If you have not trimmed your azaleas yet this year, you will need to do so this month (once the blooms have dropped). Trimming any later can affect the blooming cycle for next year. Most azaleas only bloom once a year and if you want to enjoy their beauty next year, be sure to trim them on time! If you have any large or leggy azaleas, these can be trimmed back to about a third of their height. Over time, the shrub will begin to have new growth. Hope this helps and let us know if you have any questions!
