With the exception ofreblooming azaleaslike Encore, most are done blooming for the year well before summer.
Technically, you canplant azaleasyear-round, but they may require extra care at certain times of year.
The downside is that you aren’t likely to see the blooms while picking out your plant.

Fall-planted azaleas should not be fertilizedor pruned.
Simply mulch around the plants and water them when the soil starts to dry out.
For the best chance of success,pick a sitewith morning sun only or with light, dappled shade.
Note that Encore azaleas may need a little more sunfour to six hours a dayfor the best bloom.
Azaleas may need watering two or three times a week in their first year.
Use your fingertip to check soil moisture around the base of the plant.
If you have sandy soil that drains too fast, mix in 10-20 percent compost to help conserve moisture.
With severely root-bound plants, this may be difficult.
Don’t Plant Too Deep
Azaleas need good drainage but also require adequate moisture.
Plant your azalea slightly higher than it was in the nursery pot.
The root ball should be just above the soil line.
Then, add 2 to 3 inches of mulch around the plant.
