How to Plant Rhododendrons



Rhododendrons prefer a not too hot or not too cold climate (just right!). Usually, they're best suited for USDA zones 5 through 8.

There are literally hundreds of different varieties of rhododendron flowers to suit your needs. So whether you're looking for bushier varieties, hedge varieties, or low-ground varieties, there really is a rhododendron flower for everyone.

Planting Rhododendrons:

  • Plant in spring or early fall.
  • Choose a spot that receives a few hours of sun per day. Not too shade, but not too sunny either – moderation is key here!
  • Soil should be well draining, humus-rich, moist, and acidic with a pH of 4.5-6.
  • Before planting, amend planting areas with compost or peat moss.
  • Rhododendrons have very shallow root systems so they need moist soil and mulch from drying out.
  • Purchase plants that are deep green (not yellowed), not wilted, and that are well watered.
  • Space your plants about 2-6 feet apart. Dig a hole that's as deep as the root ball and about 2 times as wide.
  • The top roots should be at the soil level or slightly below.
  • Fill the hole half full with soil and then water as to settle the soil. Once the soil has settled, fill the rest of the hole up.


  • Mulch the plants every spring with 2-5 inches of pine bark chips to protect the roots and keep moist.
  • Fertilize sparingly and only when flower buds swell in early spring.
  • Water the plants during the summer.

So now that you know how to plant rhododendrons, it's time to roll up your sleeves and get to planting!

Happy Planting!
