Pak Choi Overview

Brassica rapa var. chinensis is a tender biennial plant from the Brassicaceae family, that is often grown as an annual for the edible leaves. Commonly known as Pak Choi. Pak Choi is not as sensitive to heat and cold as Chinese Cabbage, and the striking white petioles and green leaves make it a must for edible landscaping. Can be prone to bolting in hot weather. The crisp leaves are slightly mustardy in taste.

Common problems with Pak Choi

Limit pest activity by keeping beds weed-free and handpicking caterpillars and bugs. Avoid wetting foliage if possible to prevent rots and fungal infections.
