How to Grow: Organic Red Kalibos Cabbage

Red Kalibos Cabbage is a versatile veggie with various uses and varieties. There are two main types of cabbage: loose-headed and hard-headed, with colors ranging from dark green to purple and white. Some cabbages produce most effectively at different points in the season. Early season cabbage is the sweetest, but has the shortest shelf life. Mid-season is the most familiar and fastest to grow. Late season cabbage is cold hardy and is perfect for storage. Late-season cabbages often have tightly packed heads that last three months in the refrigerator crisper!

The perfect addition to any garden! Red Kalibos Cabbage is easy to grow and there's one for every season!

Soil Preparation

Soil should be rich with organic material but loose enough to work with. Add a mixture of one part compost and one part sand to keep the soil rich and well-drained. Like broccoli and Brussels sprouts, Red Kalibos Cabbage has club root. Club root attacks the root structure and deforms it into gnarly knots and nodules. This has a negative effect on the roots' ability to absorb water and nutrients.

To prevent club root, compress the soil where you want to plant, removing air gaps that lead to the disease. Dig a trench approximately 2 inches deep and then lightly compress the soil down with your foot or by pressing firmly with your hand. The soil should still be crumbly when moved but have a noticeable density from the reduced air pockets. This is the same for any brassica vegetable like broccoli and cauliflower. Red Kalibos Cabbage thrives in most soils as long as adequate moisture is present.


Red Kalibos Cabbage requires nitrogen-rich fertilizer. Nitrogen is vital for cabbage leaf growth. Red Kalibos Cabbage is a heavy feeder because of its leaf development. It's wise to add a second helping of nitrogen-rich fertilizer 6-8 weeks after transplanting, especially if lots of rain has fallen. We apply Trifecta+ to the soil once before planting, and then again mid-season to boost the nutrients surrounding the plant.

pH Levels

Alkaline soil is best for all cabbage types. Aim for a pH of 7-7.5.


Red Kalibos Cabbage needs 5-7 hours of daily sun. The more sun they get, the better the leaf growth. Full sun is especially important for head growth.


Generally, provide 1/2 gallon or 1 inch of water per week for most climates, but ensure the soil has adequate moisture to begin with. However, Red Kalibos Cabbage is more drought-resistant than other brassicas. Apply moisture evenly late in the season, or developing heads may split. Also, avoid late evening overhead watering because this leads to diseases such as black rot and downy mildew.


If Red Kalibos Cabbage is planted too close together, they will rot due to a lack of airflow. Space them 12-24 inches apart to give enough room for the leaves to grow. This also gives you more space to harvest when the time comes.


This cold-weather crop will germinate in temperatures 45-85°F. Late-season varieties can be harvested well into December in northern climates because of their tolerance to cold temperatures. Red Kalibos Cabbage withstands temperatures down to 20°F. Plant in April for an early crop, and early July for a late crop.


Red Kalibos Cabbage takes 60-95 days to mature. As the season progresses, heads will form at the center of the greens. Harvest when the heads are firm and reach the desired size. Cabbages not harvested at the right time will split their heads. You can slow down this process by twisting the heads or slicing the roots. For the best flavor, eat it as soon as possible after picking. However, under the right conditions (35°F with 95 percent humidity), you can store cabbage for up to six months with little to no loss in quality, as long as you keep them away from apples, bananas, or other ethylene-generating fruits.
