Dwarf Pak Choi Seeds

Plant Pak Choi seeds as soon as the soil is workable in the spring. A soil temperature between 60-70°F is ideal for germination, which usually takes between 5-7 days. Brassica rapa seeds should be planted a quarter inch deep. Sowing a second crop two weeks after the first, then a third, will result in a rolling harvest rather than a single glut. When starting indoors, sow six weeks before the last expected spring frost date and make sure to keep a tray with seeds under growing light to encourage sprouts.

Full sun produces the fastest growth, but once the temperature is above 75°F, plants bolt and taste bitter. During a heat wave, provide afternoon shade to make your harvest edible. Pak Choi roots are shallow, so they dry out surprisingly fast, so consistent moisture is a must. Work compost or well-aged manure into your bed before planting to get better crops. Plant 4 to 6 inches apart with 10 inches between rows to avoid overcrowding.

Add mulch around the base once Pak Choi vegetable is established. It helps cool them, conserve moisture, and protects from temperature swings. Dwarf Pak Choi does not require a lot of fertilizer. A mid-season compost is all they need. Cabbage worms and flea beetles are the most common pests that affect Brassica rapa. Row cover takes care of both. Harvest the whole head at soil level when it reaches 2–3 inches, or pull outer leaves for baby greens earlier. Either way, cut clean and the plant moves on.
