Dig a hole 6-8 inches deep and two to three times the width of your Azalea root ball and fill it with water. If the hole drains within a few hours, you have good drainage. If the water is still standing 12 hours later, improve the drainage in your bed, possibly by building a raised bed. A soil sample is always a good idea, from any good nursery or garden center. Azaleas are acid-loving plants, so optimum PH levels in the soil are between 5.5 and 6.5.Turn and break up the soil removed from the planting hole. Mix some organic compost or peat moss with the soil. (This is especially important if you have sandy or heavy clay soil.) Remove your Azalea from its container and carefully loosen the root ball. Set the plant into the hole you've prepared, making sure the top of the root ball is slightly above the soil level. Fill the hole around the plant with your mix, water thoroughly and cover with mulch to protect surface roots.

Amagasa is a late flowering azalea (Satsuki hybrid) that typically blooms in the late spring. You want to fertilize after the blooms have faded. Fertilizing before the plant has bloomed might cause new growth to emerge that will only cover up the blooms. Because there are a lot of deer in my area, and because azaleas are acid-loving plants, I always use Milorganite to fertilizer my azaleas. This fertilizer helps repel the deer and provides naturally occurring iron for deep greening of the foliage. Milorganite is also non-burning so you don't have to worry about over-fertilization. Alternatively, you can use a specialty Azalea, Camellia, & Rhododendron fertilizer or a well-balanced, slow-release shrub and tree food that includes iron and other essential micronutrients. You can also fertilize again in early fall. For application rates, always follow instructions of the package of fertilizer.
