Swiss Chard vs. Kale: How to Grow

Chard is an ideal vegetable to cultivate as it can grow quickly and easily during the cooler temperatures of spring and fall. Additionally, it has a higher heat tolerance than other greens, making it suitable for growing even in the warmer months. This makes chard a great option for salads when temperatures get too high for other greens.

If you want to grow Swiss chard, you’ll need to find a spot with full sunlight and soil that drains well, with a pH between 6.0 and 7.0. To get a spring harvest, plant the seeds three weeks before the last frost of spring. For a fall harvest, plant them forty days before the frost date for your area. Place the seeds half an inch into the ground and space each plant six inches away from the next, with eighteen inches between each row. If you want to have a continuous supply of chard, sow new seeds at 10-day intervals.

Kale is a hardy and flexible vegetable that is simple to cultivate. It is a biennial plant, meaning it will develop leaves in the first year and then generate a flower stalk in the second or sometimes late in the first year. After this, the plant will form flowers and seeds and then eventually die.

For the best-tasting and most tender leaves, kale needs full sun and rich, well-drained soil. Incorporating compost and nitrogen-rich amendments like blood meal, cottonseed meal, or composted manure into the ground before planting will give the plants an added boost. Kale is best when it grows quickly and matures before temperatures exceed 75 °F or after fall frosts have occurred. Young plants can handle temperatures as low as 25 °F, while mature plants can withstand very cold temperatures. However, hot temperatures will lead to slower growth and a bitter flavor.

For spring kale crops, plant seeds four weeks before the last spring frost. They will germinate once the soil reaches 40 °F. For a fall crop, sow seeds 90 days before the first fall frost. Plant seeds half an inch deep, 1 inch apart, with rows 18 inches apart.

Both are packed with essential vitamins, minerals, and antioxidants that help promote overall health. Swiss chard is a good source of potassium, magnesium, and vitamins E, A, and K. While kale provides an ample dose of protein, calcium, vitamin C, as well as folate. However, the most important nutrient in these leafy greens is fiber which helps keep your digestive system healthy.

Eating a varied diet containing lots of different vegetables and fruits will ensure you get all the nutrients your body needs to stay healthy. Eating up to 30 different plants per week can provide you with a full spectrum of micronutrients such as vitamins B1-B12, zinc, copper, and selenium for optimal health outcomes. Focusing on foods rich in dietary fiber, like legumes or whole grains, can also help reduce inflammation throughout your body while promoting cardiovascular health due to their high content of omega-3 fatty acids.

To summarize, Swiss chard vs. kale: both are highly nutritious leafy green options that should definitely be included in our diets for maximum nutrition benefits! With so many varieties available, don’t be afraid to experiment with adding more variety to your meals. Not only will this give you more micronutrient diversity, but it’ll also allow you to experience new flavors too!
