Can I Plant Bok Choy in a Limited Space?

Planting Dates

• Bok choy is a cool weather crop that can be planted in either early spring or fall. Ideal growing temperatures are between 60 and 70 degrees Fahrenheit and the plants are actually very sensitive to their climate. If temperatures fall below 60 F, there is a chance young seedlings will bolt, or form seed heads, making the leaves bitter. Temperatures above 70 to 75 F can cause mushy leaves and bitter flavor. Direct-seeded fall plantings are generally the most successful.

Soil Preparation

• Plant your bok choy in a spot with full sun if you plant it in the fall. Part shade can help keep spring planted bok choy from bolting according to the Oneida County Extension. Soil should be well drained and amended with organic matter prior to planting. These tender vegetables grow best with a soil pH of between 6.0 and 7.5.

Planting Instructions

• Spring plantings should be started indoors two or three weeks before the last frost. Pest control is critical in the spring and row covers may be necessary for protection from flea beetles. Harvest spring planted bok choy young to prevent bolting. Begin direct seeding fall bok choy in July through August and continue planting until temperatures drop consistently below 60 F. Seeds should be sewn shallowly and about six inches apart in rows about 12 inches apart.

Culture

• Mulch your bok choy bed to prevent weeds and retain moisture. Competition from weeds can induce bolting so keeping a weed-free garden is important. Bok choy grows best with regular irrigation. Water until the soil is wet to a depth of 6 inches and then water again when the soil is dry. Bok choy is susceptible to some leaf fungi, so water in the morning to give the foliage time to dry before night. Regularly check for pests; flea beetles and a number of caterpillars can decimate crops quickly.
