How deep do I need to make a hole for a small azalea plant?

I'm planting it in a space at the end of my walkway. How deep do I need to dig if It will be in a raised bed, up about 5 inches off the ground.

How deep do I need to make a hole for a small azalea plant?
as deep as the pot it's in now
Reply:You generally dig a hole about twice the size of the current container when transplanting anything (not twice as deep and twice as wide, but twice the volume - for example, at least a few inches bigger all the way around for a 10-inch pot). You then throw in a little compost or topsoil back into the hole and mix it with the existing dirt to fill the hole back in to where when you set the root ball into the hole, the level of soil around the root ball is the same as the level of soil in the garden bed. Then backfill the hole and tamp down the loose soil firm enough to support the plant. Leave the extra excavated soil handy to fill in low spots that may develop after you water the plant.
Reply:For best results, dig out the bed 18 inches deep and at least 30 inches wide. Plants should be spaced 3 to 4 feet apart and at least 18 inches from the edge of the bed.
