Sun Requirements

The first step in selecting a spot in the garden to grow a kale crop is determining how much sun the area gets. Kale grows best in full sun or very light shade. Light shade is considered four to six hours of sun a day, while full sun is six or more hours per day.

Growing Season

Kale takes about 90 days to grow from seed to harvest. During this three month growing season, kale requires a temperature range between 40 and 65 degrees Fahrenheit. In mild, Mediterranean climates, plant kale in the fall when the air temperature drops to around 65 degrees F. You can grow kale through the winter in areas that get light frost.

Soil Preparation and Planting

Before you plant, get the soil ready with organic matter to improve the results at harvest. Start with a 2- to 4-inch layer of compost and dig it into the top 12 to 15 inches of the soil. Use seasoned, well-rotted compost for soil amendments. The best way to plant kale in mild climates is by direct seeding it in the garden.

Care and Harvest

Once the seedlings emerge, go ahead and thin them to a spacing of 12 inches between plants. If you wait until the seedlings are 3 to 4 inches tall, you can bring the tender kale seedlings pulled during thinning into the kitchen for a fresh salad. The whole kale plant is ready to harvest three months after planting.

How Often Should I Water Kale?

Kale, like other leafy vegetables, requires a fair amount of water to thrive and grow.

Best Soil For Kale

Kale is no different from most home-grown vegetables. It prefers well-drained soil that contains a fair amount of nutritious organic matter.

Arugula (Eruca vesicaria)

Arugula is among the fastest-growing leafy greens. It is one of those greens that people either love or hate, as it can have musky odor and taste. Some find its peppery bite very refreshing. Arugula tolerates some shade but also does well in full sun. It is easy to grow from seed sown directly into the garden.

Beans (Phaseolus vulgaris)

Like peas, beans are a little gift for the hardworking gardener; they take very little effort. There are many varieties of bush beans and pole beans that can deal with some daily shade and take up very little space.

Beets (Beta vulgaris)

Beets sort of break the rules for planting root vegetables in partial shade and can do surprisingly well. While the shade may impact the size of your beetroots, the plants will still produce delicious greens.

Broccoli (Brassica oleracea var. italica)

Broccoli is one of those vegetables that you can plant alongside the shadier edges of any garden space. It looks fantastic when growing in a row, and with all the colorful varieties available, it adds a fun splash to a border.

Brussels Sprouts (Brassica oleracea cultivars)

Brussels sprouts, another member of the cabbage family, may take a long time to grow. But they are fun to watch—that first sprout is exciting. The other benefit of this vegetable is that it can grow well into the cold season, and flavor actually improves after a light frost.

Cauliflower (Brassica oleracea cultivars)

Planting broccoli means you're almost compelled to plant cauliflower as well. Staggering this beautiful plant alongside its taller, nutty-flavored cousin can add a splash of design to an otherwise difficult shady garden space.

Collard Greens (Brassica oleracea L. subsp. acephala)

Collard greens, another cabbage relative, are among the leafy greens that fall into the class of cooking greens. It is leafy and great in a salad, but perhaps best prepared as a sautéed green dish.

How to Plant Kale

Kale can be planted three to five weeks prior to your area’s projected last frost date in the spring. It also can be planted in the late summer roughly six to eight weeks before your first fall frost. Those in warm climates (zone 8 and above) can continue to plant in the early fall for a late fall to winter harvest.

Kale Care

Kale grows well in full sun to part shade. The fullest growth will occur when the plant gets six or more hours of direct sunlight on most days. However, if you live in a hot, dry climate, provide your plant with some shade, especially from the strong afternoon sun. Heat can make the leaves wilt and lose their flavor.

Types of Kale

There are many kale varieties, and they're all worth a try. The curly-leaf varieties tend to hang on longer in cold weather. But the flat-leaf types generally become established faster. Here are some varieties to consider:

Kale vs. Chard

Kale and chard come in similar appearances. Their leaves are often large, crisp, crinkled, and deep green. Their difference comes in their taste. Kale is generally stronger, with a bitter and earthy flavor. And chard is a much more mild green.

Harvesting Kale

Expect to wait approximately two months for your kale plants to mature from seeds. Check the days to maturity on your seed packet or plant label for more precise timing. Spring-planted kale will be good for harvesting throughout the summer months, but it's especially tasty after a light frost.

How to Grow Kale in Pots

Kale is easy to keep in pots. Not only does this make the plant mobile so that you can move it into adequate sunlight and protect it from severe weather as needed, but it also helps to protect it from garden critters, such as rabbits, that might munch on the leaves.

Propagating Kale

Kale is most commonly planted from seeds or nursery plants. But it also can be propagated via cuttings. Cuttings are an inexpensive way to create a new plant. The best time to do this is in the early spring or late summer. Here’s how:

When to Plant Kale

Kale are a frost tolerant vegetable. This means the best time to plant them is mid to early spring, and mid to late summer for a fall harvest. If you’re expecting a late or early frost after planting, protect your kale with a blanket of straw or cover them with plastic buckets.

How to Plant Kale

Plant your kale seeds directly in the soil of your garden or container at a depth of 0.5 inches (1 centimetre). Seeds can be planted outside or you can germinate them indoors and transplant them later. Typically, kale seeds take about 1 - 2 weeks to fully germinate.

How to Grow Kale in Pots

The key to caring for kale in containers is well draining soil and a pot big enough for their root system. Aim for a pot that is roughly 577 cubic inches (9,455 cubic centimetres) in size. A typical 10 or 12 inch flower pot is a great container option for kale.

How Long do Kale Take to Grow

On average, it takes about 55 - 75 days from planting for a kale seed to develop into a fully mature plant.

How Big do Kale Get

Typically, kale plants reach about 1 - 2 feet (or 30 - 60 centimetres) in height. Though this can fluctuate depending on the variety.

How Much Sunlight do Kale Need

Kale need 3 - 6 hours of direct sunlight every day in order to thrive. Be careful to place your plants in an area that receives adequate sunlight. Otherwise, they may not mature properly.

How Much Water do Kale Need

Kale like well draining soil that is kept consistently moist, but not wet or soggy. The amount of water it takes to achieve this effect will differ depending on the type of soil available to you.

How to Grow and Care for Kale

Kale is a heavy feeder with an appetite for nitrogen. Organic growers should add plenty of compost or well-rotted manure to their soil. Kale can be direct-seeded or transplanted outside up to 5 weeks before the date of the last expected spring frost and succession-planted until 6 weeks before the first expected fall frost.

Kale Pests, Diseases and Problems

Kale is a fairly hardy crop, but there are still some pests and diseases that may occur.

Kale Varieties

Flat-leafed kales like White and Red Russian are prized for their tenderness and flavor, but they are susceptible to pest and disease problems as noted above.

A Multi-Season Solution

  • One of the reasons growing kale in part shade worked well for me in Zone 7b was that in spring, those big oak and walnut trees hadn’t leafed out yet, allowing my plants to get more sun. My plants were already nicely established by the time summer rolled around, and the trees provided them with some much needed shade from the summer heat. This is the strategy I still adopt in o…
