Tuberous begonias are a favorite among gardeners because of their vibrant colors and ease of care. However, aphids can pose a problem for these plants. Aphids are small insects that suck the sap from the plants and can cause stunted growth, yellowing leaves, and even death. If you have noticed aphids on your tuberous begonia plant, there are ways to get rid of them.
Before you can effectively get rid of aphids on your tuberous begonia plant, you need to identify them. Aphids come in different colors such as green, black, brown, red, and yellow. They are usually found in colonies on the undersides of leaves, stems, and flowers. You may also notice a sticky residue called honeydew on the leaves.
