Organic 'White Stemmed' Pak Choi Seeds (Brassica rapa subsp. chinensis). This open-pollinated heirloom forms an open rosette of glossy green leaves on thick, white, crisp, succulent stems. Its mild brassica flavour suits both baby leaves and more developed plants. Harvest it for salads, braising-green mixes, stir-fries, or steaming. Each packet contains approximately 150 seeds certified organic by Ecocert Canada. Picking can begin at about 30 days for baby leaves, while compact rosettes generally mature in 45 to 75 days. Cool autumn nights bring out especially good flavour. It grows quickly in cool weather. For practical seed starting, growing from seed succeeds best when the verified product depth, moisture and temperature guidance is followed.

Direct sow from early spring through midsummer, then sow again in late summer to take advantage of cool conditions. Plant seeds 0.6 to 1.3 cm deep and initially 2.5 cm apart. They generally germinate in 4 to 7 days; the packet lists approximately 6 days from 7 to 29°C, with an optimal range of 15 to 21°C. Thin to 15 cm for small plants or 25 to 30 cm for larger rosettes. Eat the thinnings as tender salad greens and keep the seedbed consistently moist. Use the product details as a clear guide on how to start seeds while keeping the growing medium evenly moist, never saturated.

Grow pak choi in full sun during cool weather or partial shade as conditions warm, using fertile, well-drained soil. Maintain even moisture to keep the stems tender and reduce premature flowering. Avoid sowing during the hottest part of summer. Harvest several outer leaves when plants reach about 8 cm tall, or cut the entire rosette when compact and firm. Flavour is especially appealing after several cool nights. Wrap unwashed plants in a damp towel or paper towel, place them in a bag, and refrigerate for approximately one week for the best texture.

Growing method

For White Stemmed Pac Choi, follow these sowing and growing guidelines for the variety. Direct-sow seeds from early spring through midsummer. Plant them at a depth of ¼-½”, spaced 1″ apart. They will germinate in 4-7 days. Provide ample, consistent moisture and thin to 6″ spacings. 1/4-1/2″ direct 7-29°C Read the packet directions before starting and keep the label so the variety remains clearly identified throughout the season. Prepare a clean, loose, well-drained growing medium and moisten it before placing the seeds so they are not displaced by the first watering. Keep the seedbed evenly moist without standing water because excess moisture reduces air around developing roots. Move seedlings into bright light as soon as they emerge and rotate containers regularly to encourage balanced growth. Where several seedlings compete for the same space, thin carefully and retain the strongest plants without disturbing their roots. Before outdoor planting, gradually acclimatize young plants to wind, sunlight, and changing temperatures over several days. Follow the stated spacing so air can move between plants and each plant receives adequate light, water, and nutrients. Water at soil level when the surface begins to dry, then adjust frequency for weather, drainage, and container volume. A light mulch can reduce splashing and moisture swings after the soil has warmed and plants are established. This seed starting sequence supports reliable growing from seed while preserving the product-specific depth and temperature facts.

Bloom period

When heat, drought, or an abrupt temperature change triggers bolting, a flower stalk carries small four-petalled yellow blossoms. They attract bees and other insects. Harvest leaves before the stalk elongates for the most tender texture, or allow several plants to flower when supporting pollinators or producing seed is desired. Read the packet directions before starting and keep the label so the variety remains clearly identified throughout the season.

Fruiting

After flowering, elongated pods produce seed. Allow them to brown on healthy plants, then cut stalks before the pods split. Finish drying under cover and thresh them into a container. Pak choi readily crosses with other Brassica rapa crops, so isolation is required to keep the variety true to type. Read the packet directions before starting and keep the label so the variety remains clearly identified throughout the season.

Harvest

Once plants reach roughly 3″, can start harvesting small leaves, 2-4 at a time, or cut entire head off for a one-time harvest. Harvest is 30-50 days after planting, but flavour is best in fall after a few cold nights.
