The shrub gets through the winter well and comes back every year; it handles the heat well. It is a good plant for the garden. Hollyhock is an evergreen perennial that is hardy to USDA Zones 5-8.
This plant is very drought-tolerant and can be grown in full sun to part shade. Hollyhocks are also drought tolerant and will tolerate a wide range of soil types. They are very easy to care for and grow well in a variety of climates.

What happens to rhododendron in winter?
Broadleaf evergreens lose water through their leaves even in the winter when the weather is warm and sunny. When the ground is frozen, the roots don’t have enough water in the soil to make up for what is lost through evaporation. If your soil is too dry, you won’t have enough nutrients to support your plant’s growth, and you’ll end up with a plant that’s not as healthy as it could be.
Where is the best place to plant rhododendron?
Unlike many blooming plants, rhododendron does not like full morning sun in winter and does best when planted in dappled shade on the north side of a building. Growing rhododendrons is best done in a location that is protected from the wind and not under eves.
Rhodods are native to Europe, Asia, and North America. below)
- They can be found in open areas such as fields
- Pastures
- Meadows
- Woodlands
- Lawns
- Parks
- Gardens
- Orchards
- Vineyards
- Fruit trees
- Shrubbery
- Hedges
- Roadsides
- They are found only in the spring
- Summer
etc. In some areas while in other areas they may be seen year-round.
The most common habitat is the open grassland, but they can also grow in dense stands of grasses and shrubs, along the banks of streams and rivers, in wooded areas and along roadways.
Some species are more common in certain areas than others, so be sure to check with your local county extension office to find out which areas are best for your plant.
Do rhododendrons survive winter?
Certain rhododendrons and deciduous azaleas can survive temperatures as low as -35°F (-37°C). As soon as the leaf cools to the desired temperature, leaf movement can be reversed. This species is found in a wide variety of habitats.
What is the lifespan of a rhododendron?
The average lifespan of rhododendron is tens to hundreds of years when given the proper care and living in the correct climate. The oldest known rhododendron is 131 million years old, while the oldest living species is 1.5 billion years old.
Should I cover my rhododendron in the winter?
PJM type rhododendrons in most years will not require extra winter care. It’s important to protect yourself from the winter sun and wind for the other years. This can be accomplished by enclosing the plant with a plastic bag. You can also cover the leaves with plastic wrap to prevent them from drying out.
If you do this, make sure that the plastic is not too thin or too thick, and that it does not get in the way of the roots. It is also a good idea to cover your plants with some sort of insulating material, such as newspaper, to keep them warm during the cold winter months.
Should I cut off dead rhododendron branches?
Maintain your rhododendron by snipping off spent flower clusters (trusses) and by removing dead and diseased wood. As soon as possible, wood damaged by storms or a harsh winter should be removed.
What does a rhododendron look like in the winter?
When temperatures fall to around 35F (2C), the leaves on the rhododendrons begin to droop. The leaves cup and curl at the edges. The leaves will be very tight around 25F. This problem is not caused by insects or disease, but by the way the plant protects its leaves during the cold winter months.
When the temperature drops below the freezing point of water, the water evaporates, leaving behind a thin layer of ice on the surface of the leaf. The ice forms a protective layer over the entire leaf, preventing water from getting into the cracks and crevices. In the summer, when the sun is high in the sky and the air temperature is warm, this ice layer melts and water can get in.
When this happens, it is called frost damage.
What time of year do you plant rhododendrons?
It’s best to plant in the spring or early fall. Depending on the mature size, the plants are 2 to 6 feet apart. If you dig a hole as deep as the root ball, it will be twice as wide. New plants should be set so that their roots are above the surface of the soil.
Fertilize with a balanced fertilizer, such as 1/2 to 1 pound per 1,000 square feet of planted area per year. Do not fertilize more than once every two years. If you do not have a soil test, consult your local county Extension office for information on how much fertilizer to apply.
Do rhododendrons grow fast?
Rhododendrons will experience a fast growth rate (2 ft. per or 60 cm) while others will slowly grow less than 0.5 in. per year (1cm). To begin with, plants that are the right size are easy to care for.
