Ampalaya, also known as bitter melon, is a popular ingredient in Asian cuisine and has many health benefits. The companion plant for Ampalaya is corn; the two plants are often grown together due to their complementary properties. Corn helps increase the yield of Ampalaya by providing nitrogen to its soil, while Ampalaya suppresses weeds that may otherwise compete with corn for resources. Additionally, planting them close together reduces pests and diseases that can affect both plants negatively. Furthermore, growing these two vegetables side-by-side can also work to improve the flavor of each crop - sweetcorn's sweetness compensates for ampalaya’s bitterness!
