Choose a spot in your yard that suits the Monrovia rhododendrons' needs. Most rhododendron prefer partial sun, all need rich, well-drained soil. Improve your soil by adding compost or manure to it, 4 inches per square foot. Work the compost or manure into the soil to a depth of 5 inches.
Plant the Monrovia rhododendron in the spring after the last frost. This will give the plant time to adjust and establish itself.
Dig a hole 2 to 3 inches shallower than the container the Monrovia rhododendron came in and two to three times as wide.
Place plant in the hole. Back fill the hole with soil, leaving 2 inches of the root ball above the soil level. (ref 3)
Water until the soil is moist. Mulch over the soil with pine needles or wood chips to keep the soil moist and prevent weeds from growing around the Monrovia rhododendron.
Pluck any flowers or flower buds off of the rhododendron. This will give the plant time to root itself.
