Days to maturity are calculated from date of direct seeding.

Culture
• Pak Choi is a cool season crop that performs best in spring and fall in a wide range of soil types
• Young plants exposed to temperature fluctuations can result in bolting
• Apply 1 cup of TSC's Complete fertilizer per 5 row feet, and 1 inch of compost

Direct Sowing
• For a spring crop, sow after the danger of frost
• Fall crops can be sown July—mid-August

Transplanting
• Sow seeds 4 weeks before anticipated transplant date for a spring crop or July/August for a fall crop

Insects & Diseases
• Common insects: Flea and cucumber beetles, slugs, earwigs
• Insect control: Pyrethrin or row covers at planting, Cabbage Collars for slugs
• Disease prevention: 5-7 year crop rotation

Harvest & Storage
• Harvest as soon as mature to avoid bolting; individual leaves can be harvested a few at a time, starting with the largest, oldest leaves
• Harvest the head when the oldest leaves are still tender; does not stand well in the garden once mature
• If bolting (sending up the flower stalk) occurs, remove the entire plant before flowers open; the flower stalk can be used like broccoli
• Store at 36°F and 95% relative humidity
