- Fertilizer
- Straw
- Pruning shears

Step 1
Plant hardy azaleas during early spring in a location that receives full morning sun and partial afternoon shade when temperatures are highest. Spread 1 inch of organic compost over the planting site, and use a garden spade to incorporate it into the soil to increase fertility and drainage. Space plants 24 to 30 inches apart.
-
Step 2
Water hardy azaleas immediately after planting and once per week during all seasons. Soak the soil to a depth of 3 inches at each watering, as azaleas have shallow root systems. Never allow the soil to dry completely or leaves may drop.
-
Step 3
Feed hardy azaleas once per month using a balanced 10-10-10 NPK fertilizer. Water thoroughly both before and after applying to prevent root burn. Apply following the directions provided by the manufacturer.
-
Step 4
Spread a 2-inch layer of straw over the soil surrounding hardy azaleas. The addition of mulch will stunt the growth of weeds, conserve moisture and regulate the soil temperature. Start the band of mulch about 3 inches from the base of the azalea to allow room for growth.
-
Step 5
Use pruning shears to cut away any dead or dying branches to help hardy azalea plants conserve nutrients. Remove the branches as close to the stem as possible to minimize damage. Pinch off any faded or dying flowers as soon as possible to encourage plants to form more blossoms instead of seed.
