Kale

Also known as: Curlies, Flower Sprout, Kalette, Decorative Kale, Flowering Kale, Flowering Cabbage

Kale is best-known as a leafy green vegetable, one of the oldest and most famous of the cabbage-mustard genus. It has been an important traditional green vegetable but has also experienced a recent rise in popularity due to its high nutrient content, often being dubbed a "superfood." There are many cultivars available, and among them, the leaf shape varies tremendously from smooth to blotched to curly. However, all are tender when cooked and crunchy when baked. Interestingly, the nutritional properties differ across cultivars as well.

Water: Kale thrives in cool climates, requiring consistent soil moisture without waterlogging. Weekly watering maintains the balance between hydration and drainage. Preferring natural rainfall and cooler temperatures, kale flourishes outdoors, enhancing leaf production and overall health.

Fertilize: For optimal growth, kale needs a balanced, high-nitrogen fertilizer (2-1-1 ratio) monthly during the growing season. Incorporate compost at planting and taper feeding in winter. Water thoroughly after fertilizing to enhance nutrient absorption and protect kale's roots from overfertilization.

Pruning: Kale features hardy foliage and benefits from pruning in early to late spring to promote growth and prevent legginess. Removing older leaves and avoiding cuts to the central bud supports health. Clean tools are essential, as proper techniques enhance vitality and yield while deterring pests.

Propagation: Kale propagation involves sowing seeds in a well-draining, fertile soil mix. Prepare the container, sow seeds shallowly, and maintain moisture through consistent watering. A warm environment aids germination, and thinning seedlings promotes robust growth by reducing competition.
