Bok Choy Seeds,
Snow White

Snow White bok choy is best planted in the cool seasons. For spring planting, direct sow around the last expected frost, or set hardened seedlings out after the last frost rather than weeks ahead of it. For fall crops, sow seeds directly in late summer to early fall when temperatures begin to cool. This variety can tolerate light frosts, but in spring two weeks or more below 50 F after the seedling stage will make it run to seedstalk instead of forming its 55-day heads.

Sow seeds 1/4 inch deep and space them 1-2 inches apart. Once seedlings reach a few inches in height, thin them to 4-6 inches apart to allow room for growth. Bok choy prefers partial shade in warmer weather to prevent bolting, but it can thrive in full sun during cooler months. Mulching helps retain soil moisture and keeps the roots cool.

Maintain consistent soil moisture and avoid letting the soil dry out, as drought stress can cause bolting. Fertilize with a balanced organic fertilizer or compost at planting time to support healthy growth. Watch for common pests like cabbage worms and aphids, and use row covers or organic pest control methods to protect your plants.

Bok choy is an annual, completing its life cycle in one year. To avoid selecting bolt-prone plants, don't save seeds from prematurely bolted ones. Let plants mature fully, harvest the dried pods, crumble the small round seeds into a jar or bag, then seal and store the seeds in a cool, dark, dry place. Bok choy cross-pollinates with other rapa species but not with different species of Brassica, so it's safe to grow it next to mustard greens (Brassica juncea), for example. To ensure seed purity, isolate your bok choy from other blooming B. rapa by about a half mile or use caging techniques. Allow your healthiest plants to flower for a strong, diverse seed pool.
