Can rhododendrons grow in cold weather?
Certain rhododendrons and deciduous azaleas can survive temperatures as low as -35°F (-37°C). ... In cold areas, certain evergreen azaleas may lose more leaves than they would in milder areas. Drying winds and frozen ground deprives plants of their natural moisture intake.
What zone is best for rhododendron?
In fact, most rhododendrons thrive in USDA hardiness zones 4 to 8. If you are pining for azaleas, you'll have to be a little more selective. Some thrive down to zone 3, but many don't grow well in such cold regions. Avoid species that are borderline hardy in favor of plants hardy to zone 4 if possible.
Are rhododendrons frost tolerant?

In cooler climates, you could also select plants that have tough leathery foliage like rhododendrons, camellias, azaleas and pieris. ...

Do rhododendrons like sun or shade?
Most large-leafed varieties require dappled shade; avoid deep shade or full sun. A sunny spot that receives a few hours of shade is perfect. See regional guidelines below. Soil should be well-drained, humus-rich, moist, and acidic (pH 4.5–6).
Why are rhododendrons not thriving?
The fungus Phytophthora species causes one of the most common disease problems in the landscape for rhododendron and azalea. This fungus is a “water mold,” and thrives in poorly drained or wet conditions. A wilted plant is usually the first sign of trouble. Rhododendron leaves will curl inward and droop.
Should you wrap rhododendrons?
Definitely do NOT wrap the plants in clear plastic. That can trap too much heat and lead to increased light or sun-scald winter damage. Some people might suggest a spray-on protectant such as Wilt-Pruf, but research has found that these have minimal - if any - effect as a winter-wind aid.
Are rhododendrons difficult to grow?
Rhododendrons need moist, acid, loose, well-drained soil that contains a good bit of organic matter. This is why they're hard to grow here. Most Southerners have either acid, clay soil or alkaline, clay soil. Rhododendrons hate both, because clay drains slowly and roots rot.
Can gardenias survive a freeze?
Gardenias are fairly hardy plants suitable for USDA zones 8 to 10. They can handle light freezes, but the foliage will get damaged with sustained cold in exposed locations. ... Frost damage on gardenia is a common complaint, but here are a few tips on how to diagnose and treat the problem.

Are rhododendrons poisonous to dogs?
All parts of a rhododendron bush, including the leaves, stems and blooms, are toxic to both cats and dogs. Only a small amount of rhododendron is needed to cause health problems.
