Coverage & Planting Details
| Coverage | This packet sows up to 43 feet. |
|---|---|
| Row Spacing | 24"–30" |
| Seed Depth | ¼" |
| Seed Spacing | A group of 3 seeds every 12"–18" |
| Thinning | When 3" tall, thin (and eat!) to 1 every 12"–18" |
| Germination | 7–12 days |
| Start Indoors | 4 to 6 weeks before your average last frost date transplanting after your average last frost date, and 4 to 6 weeks before transplanting outdoors in summer for a fall crop. Sow in biodegradable pots to avoid root disturbance. Mild Climates: Sow in fall for a cool-season harvest. |
| Direct Sow | RECOMMENDED. 2 to 4 weeks before your average last frost date for a summer crop or 8 to 10 weeks before your average first fall frost date for a fall crop. Ideal soil temperature for germination is 75°-85°F. Persistent temperatures of 50°F or below while plants are young can cause bolting (premature flowering), cover as necessary. |
| Growing & Harvesting | Harvest heads when they are well developed, firm, and solid when squeezed. Cut off heads at base with a sharp knife. Cabbages left in the ground beyond maturity are more subject to disease and splitting. Harvest in the morning if possible. If harvested in the heat, dunk in ice water to reduce "field heat" and increase storage time. Allow to drain before storing. |

- Chris S.Verified BuyerRated 5 out of 5 stars8/4/26+10 WILL buy again!
I planted these indoors under lights and on heating pads until they germinated. 49 days later I harvested four five-pound cabbages that were absolutely amazing. Recommend using Sluggo or your favorite slug/earwig deterrent because humans aren't the only creatures that love these cabbages. I made them into kimchi that is insanely good.

first time growing cabbage, high germination rate & transplanted well
- Deborah N.Rated 1 out of 5 stars2/27/26Never formed a compact head
I planted seeds in late August and again in early September in my zone 8 Oregon garden. The plants survived well, but the leaves grew outward more like a leaf lettuce. In January, the plants began to grow upward to form the beginning of a head, but bolted by the 1st of Feb. Managed to harvest a few leaves for stir fries and salad, but the plants never formed a compact head as shown in the description.

- JojoVerified BuyerRated 5 out of 5 stars10/18/25The best
I had these seeds for a few years and just didn’t plant them. I was so pleasantly surprised when I finally got them in the ground this year. Germination was great. They grew beautifully. They quickly matured and I knew they were ready when one plant started to be devoured by bugs! These were sweet and delicious. The best cabbage I have ever grown. It is now a staple in my garden. My neighbors enjoyed this, too. We have a favorite recipe that uses cauliflower, cabbage, bacon, and a sweet-and-sour mayo dressing. It is delicious. Next year I will grow cabbage along with this for a delicious homegrown meal.
