If you're considering adding bok choy to your Arkansas garden, understanding when to plant this delicious, cool-season vegetable is crucial. With its crisp white stalks and tender leaves, bok choy thrives in the moderate temperatures of early spring and late summer. In particular, for those in Zone 6b, the median last spring frost occurs on April 7, so timing your planting around this date is essential for a full harvest.
Bok choy is a fast-growing vegetable that can be harvested as baby greens just 30 days after sowing, making it one of the most productive plants per square foot. In Zone 7a, where each season offers a unique opportunity, the median last frost is even earlier, on March 29, allowing for a longer growing season. However, careful planning is necessary to avoid heat stress, which can cause premature bolting during summer months.
For Arkansas gardeners, especially those in more humid areas, fall planting can yield the best quality and the longest harvest window. As the temperatures decrease and day length shortens, bok choy is less likely to bolt, allowing you to enjoy its mild and slightly sweet flavor well into the growing season. Be sure to idealize your planting schedule to take advantage of both the early spring and the fall frost-free periods.
| Zone | Indoor start | Transplant out | Direct sow | Harvest |
|---|---|---|---|---|
| Zone 6b | Start February 15 – March 1, ~6–8 weeks before April 7 | Transplant outdoors April 20 – May 1, after the last frost | Direct sow April 20 – May 10, once the soil warms | Harvest from June 1 until July 15, before summer heat |
| Zone 7a | Start February 15 – March 1, ~6–8 weeks before March 29 | Transplant outdoors April 10 – April 20, after the last frost | Direct sow April 10 – May 1, as soon as conditions allow | Harvest late-May through early July, then again from late September until November |
| Zone 6a | Start March 1 – March 15, ~6–8 weeks before April 16 | Transplant outdoors April 25 – May 5, once frost risk is low | Direct sow April 25 – May 15, when the weather stabilizes | Harvest early June until late July, and again from late September to October |
Gardeners in colder areas should start their bok choy seeds indoors to ensure robust seedlings. This gives you a head-start despite the colder temperatures typically experienced in these regions.
Planting in May can be risky due to the rising temperatures in Arkansas, which can lead to bolting. It's best to plant earlier or wait for a fall planting.
Using floating row cover at planting can eliminate most cabbage worm damage. Regularly check the undersides of leaves and use strong water sprays to manage aphids effectively.
Yes, bok choy can thrive in containers, provided they receive enough water and nutrients. Ensure your containers have good drainage and place them in an area with sufficient cool temperatures.
If you notice your bok choy bolting, it's best to harvest it immediately. You can still use the edible leaves, and quick harvesting can help prevent further bolting.
