Companion planting bok choy is a strategic gardening practice that enhances growth, deters pests, and optimizes space by pairing bok choy with compatible plants. This method leverages the natural relationships between plants to create a more resilient and productive garden.
Understanding Bok Choy's Growing Needs
Bok choy (Brassica rapa subsp. chinensis), also known as pak choi, is a cool-season leafy green vegetable that thrives in the following conditions:
-
Soil: Rich, well-draining soil with a pH between 6.0 and 7.5.
-
Sunlight: Full sun to partial shade.
-
Water: Consistent moisture, avoiding waterlogged conditions.
-
Temperature: Optimal growth occurs between 55°F and 70°F.
Understanding these requirements is crucial when selecting companion plants to ensure compatibility and mutual benefit.
