How to grow Kale
Kale is a great fall and winter vegetable to grow in your garden. It is easy to grow! It is very hardy and is able to withstand the severest of winters, producing plenty of tops for use during January, February, March and early April. Want to grow easy vegetables that produce in the coolest weather? Want to grow the most nutrient dense foods? You need to know how to grow Kale!
Kale is rich in beta-carotene, vitamin C, and other substances that protect against cancer. It contains fiber and various minerals (especially iron and calcium- ounce for ounce about as much calcium as whole milk in some cases), and has the richest source of vitamin C among the leafy greens. These along with many other characteristics make Kale a legitimate superfood!
This plant will grow in the poorest of soils but responds favorably to richer soil high in nutrients, and seems not to be troubled by diseases which strike many other winter growing vegetables, especially club root, which attacks brassicas generally; however good drainage is necessary. I have had Kale plants literally grow for two plus years in my backyard garden.
How to grow Kale
Kale is one of the easiest plants to grow in your backyard garden. It will grow great in shade or full sun, it tolerates the hot summer temperatures and powers through most winters. Let’s get planting!
If you plant early in the year, consider using raised beds to allow better drainage during the winter months. Kale can be planted out after early potatoes or peas without any adding extra fertilizers, however if the soil is particularly poor, rake in some fish manure at 2 oz. (60g) to the sq. yd.
It depends on the variety you are sowing as to the time the seeds should be sown, some are sown early during May or June whilst others are sown later in July and August, but generally they are sown in June and July just as many early crops are harvested and the land becomes vacant.
Start your spring crop indoors four to six weeks before planting them outdoors. Plan to plant your seedlings outdoors very early in the season and after the last frost date for your area. Plant seeds in containers 1/2 in. (12mm) deep in sterile starting mix. Water thoroughly once, then lightly after the seeds have sprouted. Provide plenty of sunlight or artificial grow lights so the plants do not become spindly. Boost your plants health with a light application of liquid fertilizer once or twice during this period.
Seeds can be direct sowed into the row or seeded in a separate area and transplanted to the row after a few weeks. If the seeds are planted together in a seedbed they can be later transplanted into the position where they are to mature and you can then better control the spacing. If you are sowing directly where the Kale is to grow, sow in drills 1 in. (25mm) deep the drills being 2-½ ft. (75cm) apart, putting in three seeds every 2 ft. (60cm) along the drill. Later the seedlings can be thinned out only allowing the strongest one to remain in each station. Whether direct seeding or transplanting make the final spacing 18 to 24 inches (45cm-60cm) apart; the outer leaves of a healthy plant will spread and cover a lot of space.
How to grow Kale: General Care
Keep down the weeds with a hoe. In dry weather make sure that the vegetable has enough water to make good growth, this is particularly important during the late summer. All members of the cabbage family are extremely susceptible to insects. Kale is no exception. Among the most common are aphids, and cabbage loopers, cabbage loopers the larva stage of a moth. Effective treatment is to place a screen over the plant so the moth cannot lay her eggs. Aphids should be sprayed with a garlic wash to deter them from penetrating the leaves.
Kale can be harvested at basically anytime after leaves have formed. The smaller leaves are more tender and can be used in salads while it is better to use larger leaves for soups and cooked dishes. Consistently picking the leaves, will then encourage the development of more nutritious leaves. This will provide plenty of leaf until the end of April. Like the other Brassicas, kale’s leaves become much sweeter after experiencing a good frost.
