The Amaumau fern benefits greatly from pruning in early spring. By removing dead fronds, you can promote healthy growth and help prevent pest infestations. It's crucial to use clean and sharp tools to reduce the risk of diseases. This practice encourages the fern's development during its recovery period, enhancing both its vigor and appearance.
