Pac Choi (Bok Choy) - Key Growing Information

A head of 'Asian Delight' pac choi, grown to full-size, with broad, light-green petioles and dark-green, oval leaves.

CULTURE:

Sow from early spring through midsummer. In the South, pac choi is well adapted for fall plantings. Suitable for fall sowing in mild climates or in a high tunnel or other protected structure in colder climates. Premature bolting of seedlings may occur if temperatures drop below 50°F (10°C), especially over multiple nights. Cold temperatures generally do not cause bolting of plants past the seedling stage.

DAYS TO MATURITY:

From emergence after direct seeding.

TRANSPLANTING:

Start seeds in 128 or 72-cell trays, 2–4 weeks before transplanting. Plant out before seedlings become rootbound or stressed to prevent premature bolting.

DIRECT SEEDING:

Sow 15 seeds/ft., 1/4" deep in rows 12-18" apart. Thin plants as recommended in our Pac Choi Comparison Chart. For baby-leaf production of 'Rosie', the only pac choi we recommend for baby leaf, see the Baby-Leaf Brassica Greens culture.
