Rhododendrons are typically found in temperate to subtropical regions of the world. They are particularly common in the mountainous regions of East Asia, particularly China, Japan, Korea and Taiwan.
Pruning in February is possible, but it is important to note that this is done before new growth begins. Use sharp, clean pruning shears to ensure a clean cut and minimize the risk of disease. If necessary, you can make light topiary prunes in February to improve the shape of the plant.
