watering
The swamp azalea should be watered regularly, aiming for damp, not soggy, soil. The best way to tell if your azalea needs watering is to check the soil. If the top 2 inches of soil feel dry, it is time to water. During the growing season, water often enough so that the soil stays moist but not wet. In hot, dry weather, azaleas may need to be watered 2-3 times per week. In the cooler months, the plants can survive with less frequent watering, about once a week or every 2 weeks. However, underwatering can slow down the growth or cause bud drop, so be sure to provide adequate moisture.
sunlight
Swamp azaleas need full to partial sunlight to grow and thrive. The ideal amount of sunlight for a swamp azalea is 4-6 hours of direct sunlight each day. It's important to note, however, that during the hottest part of the day (noon to 3 pm) swamp azaleas should be placed in partial shade to prevent leaf burn and sunscald. If swamp azaleas are not exposed to enough sunlight, their flowers may not open and they may not reach their maximum growth potential.
pruning
Swamp azaleas should be pruned in late winter or early spring. If the bush becomes too large, it can be reduced in size by cutting back specific branches. Light pruning of stems in the middle of the bush is recommended to create an even and rounded shape. Shorten stems to 2-3 buds above the desired shape, while taking care to not remove more than 1-third of the total structure of the bush. Any dead or diseased branches should be removed.
