A classic shade garden plant, rhododendrons are prized for their glossy green foliage and showy clusters of blooms. Available in a variety of hues, the most common flower colors are purples and pinks, as well as white and cream. The\u00a0Rhododendron<\/em>\u00a0genus contains an option for every landscape, from the giant rhododendrons of East Asian mountainsides to the rosebay rhododendrons native to Eastern U.S. woodlands. In areas where dry winters tend to desiccate evergreen types, deciduous varieties of rhododendrons can fill in the gap. Many deciduous types also boast bright yellow and orange hues that work wonders in brightening up shady corners of the garden.<\/p>

\u00a0<\/div>

When ingested, the leaves, nectar, seeds, and flowers of\u00a0rhododendrons and azaleas are toxic to humans and pets.<\/p>

Rhododendron or Azalea?<\/span><\/h2>

Rhododendrons and azaleas are often confused. Azaleas were once considered a separate genus of plants, but they were reclassified as genetically similar to rhododendrons relatively recently. Now, they are in the same genus. People tend to think of rhododendrons as large evergreen plants with big clusters of blooms and associate azaleas with smaller leaves and shorter plant habits.<\/p>

\u00a0<\/div><\/span>

Where to Plant Rhododendron<\/span><\/h2>

Rhododendron plants, like many other plants in the Ericaceae family, prefer acidic soils. Many of the evergreen types can be susceptible to burn in winter where they are exposed. To prevent this, plant evergreen types in sheltered areas, avoiding southern exposures where\u00a0warm, sunny winter days can be fatal. Keep them sheltered from drying winter winds as well.<\/p>

\u00a0<\/div><\/span>

Rhododendron Care Tips<\/span><\/h2>

Light<\/span><\/h3>

Most rhododendrons\u00a0prefer a shade-filled existence, but newer varieties are available for sunny areas as well. Deciduous varieties can hold up much better to more sun.<\/p>

\u00a0<\/div>

Soil and Water<\/span><\/h3>

The ideal soil pH for rhododendron plants is somewhere between 4.5 and 6.0. If you have had problems growing rhododendrons in the past,\u00a0perform a soil test. You can amend the soils with peat moss, compost, and other soil acidifiers to keep them happy.<\/p>

\u00a0<\/div>

Rhododendrons also appreciate soil that has\u00a0lots of organic matter. This will keep the shrubs decently moist and prevent them from drying out (dry winters and late falls can be particularly fatal to rhododendrons). On the other end of the spectrum, overly wet soils can also be fatal to rhododendrons. Finding the right balance of moisture in soils can be tricky.<\/p>

\u00a0<\/div>

Fertilizer<\/span><\/h3>

Fertilize rhododendrons and azaleas soon after blooming ends.\u00a0Add a slow-release granular fertilizer\u00a0to the soil or mulch around the plants. Use a fertilizer especially labeled for rhododendrons or a high-quality compost.<\/p>

\u00a0<\/div>

Pruning<\/span><\/h3>

Pruning may be necessary to create a more desirable shape and overall more visually appealing plant. After the plants have bloomed, spent blossoms can be cut back to the new growing tips. After bloom is also the\u00a0ideal time to do any other pruning. Damaged or diseased growth should always be removed to prevent the spread of disease. You can also do rejuvenation pruning by cutting older plants back more severely to encourage better branching.<\/p>

\u00a0<\/div><\/span>

Pests and Problems<\/span><\/h2>

Rhododendrons and azaleas are not particularly susceptible to insects, but they sometimes are afflicted by lace bugs, borers, or weevils. Prevent an infestation by choosing resistant species or hybrids that show resistance and by keeping the area around the plant cleaned up.<\/p>

\u00a0<\/div>

Gardeners who live in\u00a0areas with a large deer population\u00a0may have a problem growing rhododendron. Deer love to munch on the leaves of the plant. In these areas, gardeners need to be willing to share, erect fencing or plastic mesh barriers, or\u00a0use a spray that repels deer.<\/p>

\u00a0<\/div>

Evergreen types may begin to curl their leaves during the winter. This is a physiological response to dry winter weather. By curling their leaves, they are\u00a0protecting themselves from cold temperatures\u00a0and winds to prevent potential winter burn.<\/p>

\u00a0<\/div><\/span>

How to Propagate Rhododendrons<\/span><\/h2>

The easiest method for a home gardener to propagate a rhododendron or azalea is by layering an existing plant. Weigh a lower branch down until it touches the soil. Cut a slit in the branch where it touches the soil and apply a rooting hormone. A couple of years later, cut the rooted branch to separate it from the parent and transplant it.<\/p>

\u00a0<\/div>

Another propagation method is by\u00a0stem cuttings taken from new growth\u00a0in the early fall. Dip the cuttings in rooting hormone, plant them in a planting medium and keep them in a warm place. Rooting occurs anywhere from 6 weeks to 4 months later.<\/p>

\u00a0<\/div>

When growing from seeds, sow them indoors in early winter on top of a moist potting soil. Maintain a high humidity, warm environment with no direct sunlight. Transplant the tiny seeding to individual pots. It will be about two years before they can be planted in the ground.<\/p>

\u00a0<\/div><\/span>
