Can you cut rhododendrons back hard?
To see if your shrub can handle such a hard pruning, cut only one of the main branches back to 6 inches. If you’re sure the others are healthy, cut them back to a height of 2 feet.
If new growth emerges from the 6-inch cut, you can cut back the rest of the shrub the following year and be confident that it won’t grow back. If you don’t have the time or patience to prune your own shrubs, your local nursery or garden center may be able to do it for you.
What month is late winter?
The late winter is when the spring thaw begins. Depending on your climate, this could happen any time in january to may. Use your average last frost date and last freeze date to determine when to plant.
If you plant in late winter or early spring, you will need to wait until the soil is warm enough to allow the roots to grow. If you wait too long, your plants will not be able to survive the winter and you may have to replant them in the spring.
How do you prepare rhododendrons for winter?
