PINE TREES AND AZALEAS
Thanks for writing. You don't have to have raised beds, and in fact, putting raised beds underneath your pines could hurt them.
I'd dig holes where you can and plant directly in the ground around your pines. Note, though: Because pines have such large and established root systems, you'll need to keep your azaleas very well watered while they become established.
