In warm weather, plant them under some shade. For the best flavor, you should grow Kale in cold weather. If you wish to plant Kale in early spring, start them indoors in late winter.

How to Grow Kales

There are many ways to plant, grow, and care for Kale. Regardless of which method you opt for, the end will justify the means. The bare truth is that Kale is easy to grow.

  • Kale can grow from seeds that are directly planted in garden soil. Also, you can start the seeds indoors then transplant them.
  • They can be first planted in nursery beds then transplanted.
  • Kales can be grown in containers and raised garden beds for those with limited space.
  • They can also be grown as a cut-and-come-again veggie. This is when you harvest the amount you require and then leave the kale plant to continue growing.

How to Grow Kales

Growing Kales from Seeds 

As aforementioned, you can start them directly by direct-seeding in your garden or start the kale seeds elsewhere then transplant into the garden. 

If you opt for the direct seeding in a cold climate, ensure the soil temperatures are at least 450 F (70 C). When provided with sufficient light, such plants grow slower outdoors than indoors.

Alternatively, you can start the kale plant indoors then transplant them after six weeks. The transplant should be once the frost is over. This allows them to mature before the hot summer-a time when they tend to turn woody and bitter. 

Planting Kales

Planting Kales

As stated earlier, you can plant Kales in containers or the ground. Kale can be planted at any time. However, it does best and produces the sweetest taste when grown in cold temperatures.

When transplanting Kale seedlings, follow this procedure:

  • Dig a hole.
  • Pop the kale seedling in the hole at a depth of 1 cm.
  • Back-fill the hole with soil. Ensure the new plant if firmly anchored into the ground.
  • Maintain a spacing of 30-40 cm between your kale plants. This allows for air circulation and provides them room to spread. For Kales meant for smaller salad leaves, the spacing can be reduced to about 25 cm apart.
  • After planting, water them correctly, donation’s over-water.
  • Usually, Kales germinate within 5-8 days.

In case you’re planting during the warm season, sow in partial shade. If you are growing during cold temps, ensure you produce where your crop will get optimal sun. 

Whereas you can inter-crop Kale with veggies such as cucumbers, spinach, onions, potatoes, and herbs, they hate growing next to beans, tomatoes, or strawberries.

How Long Does Kale Take To Mature?

Direct kale seeds usually take approximately 55-75 days to mature. However, transplants speed up the process and develop after 30-40 days. After maturity, you can go on harvesting your Kale even after snowfall.

We recommend planting more transplants or seeds (whichever you prefer) every 2-3 weeks. Doing so ensures you have a long and continuous harvest.

How to Care For Kale

  1. Watering. Always ensure your kales are well watered. This encourages consistent growth and ensures the leaves don’t get too harsh. During seasons when rain is inconsistent, provide them with 1-1.5 inches of water (app. 1 gallon per square foot) every week. 
  2. Feed Them. Yes, you read that right. Kales need feeding as well. Side-dress them with compost every 6-8 weeks. It helps boost their growth throughout the season.
  3. Mulch. Mulching the soil hinders the growth of weeds by smoothing them. It also helps keep your kales cool under the required soil temperature and makes it easier for kale roots to feed.
  4. WeedingKeep the kales well weeded. It reduces competition for nutrients. 
  5. Use row covers to stave off pests such as flea beetles. Row covers also buffer against unexpected temperature changes.
  6. Pick of unhealthy leaves. Prune off any damaged or unhealthy (yellowish) leaves as soon as you sight them.
  7. Use a mound straw. Once your kale plant is 6 inches high, use mound straw around them. It prevents them from touching the soil, something that could affect their quality.
  8. Pests control. Slugs and birds such as pigeons can be a nuisance to your Kale. For the slugs, handpick them or set slug traps to eradicate them. Here are various ways to get rid of birds out of the garden. For other pests, we recommend the use of natural ways to eliminate them.
