Know Your Plant – Kale

The mustard family’s loose-leafed food plant kale (Brassica oleracea, variation acephala) (Brassicaceae). Kale is primarily cultivated for its fall and winter harvests when the cold weather enhances the nutritional value and flavor of the leafy green.

Kale’s resilience makes it possible to harvest fresh greens even after most other fresh vegetables have gone out of season. Vitamin A, vitamin C, calcium, iron, and vitamin B6 are all found in the leaves, consumed fresh or cooked.

The leaves of the kale plant are long and wavy to frilled, forming a rosette. Although the foliage is normally blue-green, the variation might have pale green, crimson, or purple leaves. Longer growing seasons allow the main stem to grow up to 60 cm (24 inches). 

Cutting the whole rosette before the stem elongates or gradually removing the lower leaves as the main stem elongates (particularly in places with lengthy, chilly growth seasons) is an option.

Although kale is often planted annually, it is a biennial plant that blooms in loose clusters in the second year with yellow four-petal flowers. The fruits are siliques, which are dry capsules.

Planting and Growing Kale at Home

Numerous kale (Brassica oleracea) cultivars exist, the most popular of which are Red Russian, Lacinato, and Hanover Salad types. The fundamental requirements for caring for various types of kale are the same for all of them.

#1 Season

Biennial kale requires two growing seasons to complete its life cycle. Kale is a good example of this. If you’re going to grow kale, it’s best to do it annually and harvest it at its peak after the first year. It is possible to grow kale in cold weather, and a mild frost will make kale leaves softer and sweeter. 

Kale will get bitter in the middle or late summer if it’s too hot.

Kale can’t withstand freezing temperatures or snow without a cold frame. Kale thrives at a temperature range of 65 to 75 degrees Fahrenheit. In most regions, kale flourishes from the beginning of spring to summer.

#2 Soil

Kale thrives on nutrient-rich soil that is also acidic in pH. Mulch is a great way to maintain the temperature of the soil at a more manageable level. The growing season is ideal for incorporating compost or other organic matter into your soil.

#3 Pests

Aphids, flea beetles, and cabbage worms are just a few of the many pests that may attack your kale plants. Use row covers to keep pests away from your kale, then remove worms from the leaves by hand. Keep an eye out for black dots on your kale, which might indicate an aphid infestation. As an insect repellent, sage is a suitable companion plant for kalé.

#4 Light

Kale plants may tolerate both full sun and moderate shade. Depending on the temperature, kale plants need different amounts of sunshine. Partial shade is good when the temperature is hot, and the humidity is low. Kale plants thrive in full sunshine if the weather is moderate.

#5 Water

Your kale plants will thrive if you give them lots of water. Sweet and soft leaves are the result of soil that is well-watered. If you’re growing kale in a hot, dry region, you’ll want to use a mulch to assist the soil to retain moisture.

Important Tips to Increase Kale Harvest

  • Most kale cultivars are ready for harvest between 70-95 days of direct seeding and 55-75 days of transplanting, depending on how they are grown.
  • It’s time to harvest when the leaves are around the size of your hand. It is possible to remove the stems from the crown.
  • Start with the largest leaves first. Your harvest season and yield will be extended as a result of this.

  • Kale keeps well for a week in the fridge in a plastic bag.
  • The fragile leaves may be eaten raw in salads, smoothies, or cooked according to preference.
