|I have five azaleas in front of my house. Some are doing very well and have many spring blooms. A few aren't. In fact, their size is still pretty small and they have been in for three years. Also, when is a good time to prune them?|
|Some azaleas grow best in full sun but others grow best in partial shade. Try to find out which azaleas you're growing so you'll know whether or not they have specific sun or shade requirements. You might also have your soil tested - azaleas tend to prefer acidic soils. Azaleas typically bloom in the late spring so pruning in early summer will encourage new growth and give the plants time to develop flower buds for the following spring's floral display. You might also want to feed lightly with a special rhododendron/azalea fertilizer. You should see an improvement in their growth a few weeks after feeding.
Best wishes with your azaleas!
