Now, let’s move to the main parts. We will break your gardening process into three steps for you to follow easier. 

Step 1: Choose the right time

Red Russian Kale is as cold-resistant as other kale varieties. Although the plant can withstand heat, colder temperatures are better for it. Hence, spring and fall are the perfect times to cultivate. 

It would be best to choose the seed sowing date based on the growing zone: 

  • Zones 3 to 5: April and July
  • Zones 6 to 8: March and August
  • Zones 9 or above: February and September

Step 2: Sow the seeds

You can sow the kale seeds outdoors or indoors, each with a different sowing method. 


When the outside temperature is over 50°F, directly sow your seeds in your garden. Plant them 18 to 24 inches apart, 1/4 inch deep, and six seeds for each row foot.

When the plants grow 8 to 12 inches, thin them. Then, you can eat the thinnings.  


If you decide to start your seedlings indoors, please take these steps:

  • Fill a tray with seed starting mix. 
  • Plan two seeds per cell, 1/4 inch deep. 
  • The ideal soil temperature for seed germination is 75°F.
  • Thin to one plant per cell. 
  • Try to maintain the greenhouse temperature at about 45°F at night and 85°F during daylight. 
  • Harden off your seedlings about one week before transplanting. 
  • Transplant the seedlings in your garden. Remember to set them 8 to 12 inches apart and 18 to 24 inches between the rows.

Step 3: Control pests and diseases

First, some gardeners experience wilting, thinning, and yellow leaves. Thrips are the common cause of this problem. You can treat those pests using neem oil or insecticidal soap.

Besides, leafy vegetables, like kale and zucchini are also prone to damage by aphids or cabbage worms. A forceful hose spray or manual picking can help get rid of these pests. You can also use covers to keep away from your vegetables. 

There are instructions for every insecticide. Take time to read labels and use products that have obtained food safety certification.

Step 4: Harvest

Baby kale is ready for harvest about 25 days after sowing, whether you transplant it or plant it directly. You can generally pick full-sized leaves for around 50 to 65 days.

If you grow Red Russian Kale in the spring, the mature time will be shorter than in the fall because the spring days are longer. 

You can harvest Red Russian Kale in the same way as other varieties of kale. Remember never to pick the interior parts of fresh growth; just go for the outer leaves.

Extra Tips For Growing Red Russian Kale

The instructions above can help you plant the kale properly. But for the best outcome, we recommend the following tips:


In most areas, kale requires full sun to some shade. It grows most strongly when receiving at least six hours of direct sunshine daily.

Give your crop some shade, particularly from the harsh afternoon light, if you live in a dry, hot region. The leaves may wilt and lose their aroma in hot weather. 


Kale plants prefer a rich, organic soil that is a little acidic. You should opt for a pH level of 6.5 to 6.8. Besides, for robust leaf growth, the nitrogen content in the organic matter should be high, and the soil must drain efficiently.

Red Russian Kale grows best in 1 to 1 1/2 inches of watering per week and demands a constant water supply. Also, keep the soil around your plant equally damp but not soggy. 

If you want to yield crisp and sweet kale, keep the soil moist all the same. You can mulch around your plant to keep the soil cool and retain moisture. 


Sprinkle fertilizer in the top three to four inches of soil before planting. Then, feed the plant as directed on the fertilizer label during the growing season. Try to use high-nitrogen compost or fertilizer for this step.
