The Care of Rhododendrons


Rhododendron plants are commonly found in gardens across the United States. These hardy evergreen plants are excellent additions to a garden not only because of their beauty but also because of their ability to withstand pests and disease. Rhododendron blooms vary in color from light pinks to darker purples and congregate in snowball shapes, forming masses of color that bring life and character to your lawn and garden. Follow these simple steps to properly care for rhododendron plants and bring their beauty to your home and garden.

Step 1

Plant the rhododendron in an area that receives partial sun during the daytime. Rhododendrons thrive in warm temperatures and will do best if they receive proper sunlight.

Step 2

Apply a thick layer of mulch around the base of the rhododendron. The mulch will help to prevent weed growth. The mulch should be approximately 6 to 8 inches in depth.

Step 3

Water the rhododendron plant frequently. Rhododendron plants have shallow roots and dry out quickly. Water until the soil and mulch around the plant is moist to the touch.

Step 4

Add a water-soluble fertilizer to every other watering session. The fertilizer will ensure the rhododendron has proper nutrients for optimal growth. You can purchase a water-soluble fertilizer at your local department store or garden specialty store.

Step 5

Prune the rhododendron as needed with pruning shears. Prune away any growth that is diseased, dead, dried out, or browning. Frequent pruning will keep the plant healthy and looking its best.
