Easy to Grow and Harvest

Kale plants are one of the easiest vegetables to grow and harvest, making them an ideal choice for beginner gardeners. Kale plants prefer cooler climates, grow best in rich, moist soil, and thrive in full sun. They are easy to maintain, low maintenance, and highly resilient to pests and diseases.

Kale plants can be started from seed in the early spring or late summer and should be planted in a row and spaced at least six inches apart. For optimal growth and harvest, the soil should be cultivated often and kept moist by regular watering.

It is important to note that kale prefers cooler temperatures and may not fare as well in hot climates. When harvesting, it’s important to cut the outer leaves while the plant is still young, leaving the center of the plant to continue to grow. Once harvested, the leaves can be used fresh or frozen to be utilized later.

Choosing the Best Location

Kale plants prefer partial shade to full sun, so pick an area that gets at least four to six hours of direct sunlight but has some shade in the afternoon. You should also look for a plot of land rich in organic matter and has good drainage; kale plants do not tolerate excessive moisture or poorly drained soils. Additionally, ensure your chosen location is away from trees or other plants that give off root exudates that could inhibit growth. Before you begin planting, double-check that the soil pH is between 6.0 and 7.0; add lime if necessary to achieve this pH. If you live in an area with extreme temperatures, consider putting the kale plants in containers to ensure they’re not exposed to temperature fluctuations.

Selecting the Best Variety

Consider the flavor

Kale plants come in many varieties, each with slightly different flavors. For example, Siberian kale is known for its sweet and mild flavor, while Red Russian kale is somewhat pungent. If you’re unsure which flavor you prefer, try growing several varieties and see which you like the most.

Consider the growing season in your area.

Different varieties of kale only grow in certain seasons and climates. Some types, like Red Russian kale, are cold-tolerant, while others, like the Scarlet kale, need a long hot summer to thrive. Picking a suitable variety for your region is essential for successful harvesting.

Consider the type of kale you’d like to grow.

Kale can be classified into three main types: Curly kale, Dinosaur/Lacinato kale, and Red Russian kale. Each of these types has distinct texture and flavor characteristics. Depending on your tastes and preferences, you may like one kind of kale over others.

Remember that you can also find pre-mixed kale seed packs at most garden supply stores. These packs usually contain different varieties of kale, which can be a great way to experiment with different flavors and textures.

Soil Preparation

Make sure you’re using a rich, well-draining soil mix. Kale plants need a soil that is high in organic matter, so you might want to consider adding compost or aged manure to your soil mixture before planting. Additionally, you want to make sure your soil is pH balanced – kale grows best in slightly acidic soil that is between 6.0 and 6.5 on the pH scale.

Once you’ve prepared your soil, you can add some additional nutrients to help your kale plants; a nitrogen-rich fertilizer is a must. You can also consider adding phosphorus and potassium to ensure your soil – kale grows best in slightly acidic soil.

You should make sure your soil is well-tilled before planting your kale seeds. Tilling your soil will help aerate it and break up any clumps of soil, which will help the soil better absorb moisture and nutrients. Once you’ve tilled the soil, it’s time to plant your seeds!

Planting Kale

You can start your kale seeds indoors about six weeks before your last frost date. Plant the seeds 1/4 inch deep in a shallow container filled with damp potting soil. Place the container in a warm, sunny spot and moisten the soil.

After the last frost, the seedlings will be ready to transplant outdoors. Choose a spot with good air circulation and ensure the soil temperature is at least 50℉. Dig a hole twice the size of the container and lightly sprinkle some compost or fertilizer in the hole. Carefully remove the seedling from the container and place it in the hole, then refill it and press down gently. Water the seedling thoroughly and keep it moist.

Kale is a hardy vegetable and does not require much maintenance. Water regularly, about once a week, and fertilize it about once a month. Leaves can be harvested as soon as they form, with the flatter leaves usually being the tastiest. Be sure to remove yellow or dead leaves from the plant to keep it healthy.

Caring for Kale Plants

– Provide adequate water: Kale loves even, consistent soil moisture for optimal growth. Make sure the soil is moist but not soggy. If your area is prone to drought, mulch your kale plants to help keep the soil moist.

– Fertilize your kale plants: After each harvest, apply a light scattering of fertilizer around the base of the plants. Any organic fertilizer that is high in nitrogen and potassium is suitable.

– Prune regularly: Since kale is an upright, vining plant, it’s essential to prune it regularly. Trim and shape the plants to keep them from becoming too tall or top-heavy. This will also help air circulate freely throughout the plant, reducing the risk of disease.

– Protect plants from temperatures below 32°F: Kale is an excellent season crop, so frigid temperatures can damage the plants. Covering plants with frost cloth or bringing them inside for a few days may help to protect them from freezing temperatures.

These simple tips can help ensure that your kale plants stay healthy and productive. Happy gardening!

Watering and Mulching

As with all vegetables, you should ensure that your kale plants get enough water regularly. The specific amount of water needed will depend on a few factors, such as the time of day and the surrounding environment. Generally speaking, your kale plants should be watered about once a week or whenever the soil looks dry. You can also use a moisture meter to check the soil’s moisture level.

When mulching your kale plants, it’s essential to use organic matter, such as straw, leaves, or grass clippings. These materials help protect the roots of the plant from the sun’s heat and retain moisture in the soil. Additionally, they reduce the number of weeds, keep the soil loose, and allow the roots to spread out, which can increase the plant’s yield. When mulching your kale plants, spread the mulch out evenly and keep it at least three inches away from the plant’s stalk.

Fertilizing and Weed Control

Fertilizing is beneficial for kale plants as it helps to provide essential nutrients for the plant. It is recommended to fertilize the plants several times throughout the growing season, typically once every three weeks. Make sure to follow the instructions on the fertilizer product you are using, as different products may have other instructions.

Weed control is also essential when growing kale plants. Weeds can compete with your kale plants for scarce resources, such as water and nutrients. The best way to control weeds is to remove them physically by hand. You can also use an herbicide if they are too difficult to remove manually. Be sure to read and follow the directions on your product, as using too much herbicide may damage your kale plants.

Pest and Disease Control

The most common pests affecting kale plants are aphids, flea beetles, and slugs. Aphids are small, soft-bodied insects, typically green, black, or yellow. They can quickly multiply and can be seen on the underside of leaves or underneath the stems of plants. To help keep aphids away, try planting flowers such as dahlias, alyssum, and marigolds near your kale.

Flea beetles are small and usually black or dark brown. These pests feed on kale leaves, often leaving behind small holes. To help prevent flea beetle infestations, avoid overwatering your kale plants and remove any diseased or rotting plants to reduce their habitat.

Slugs are giant, soft-bodied, usually gray, black, or brown. They feed on kale leaves, leaving large, ragged holes in the foliage. To get rid of them, try sprinkling diatomaceous earth around the base of the kale plants or handpicking them off the foliage.

If your kale plants become infected with a disease, they must act quickly. Common conditions affecting kale include powdery mildew, leaf spot, and clubroot. Powdery mildew is a powdery fungus that spreads over the plant’s leaves. To help prevent it, water your kale plants at the base and avoid overhead irrigation. Leaf spot is caused by a fungus and can be identified by small, dark spots on the leaves. To help prevent it, avoid wetting the foliage when watering and keep the area around your kale plants clean and free of debris. Clubroot is a soil-borne disease that can cause stunted or wilting growth and sunken, cracked roots. To avoid clubroot, ensure your soil is well-draining and often rotate your crops.

Harvesting Kale

Harvesting kale is an exciting part of growing the kale plant. With kale, you can expect to harvest it from the same plant multiple times throughout its growing season. The best time to harvest kale is when the leaves are young, tender, and sweet. The growth of the plant will determine when it’s ready for harvesting.

Once your kale plants are ready to be harvested, you’ll want to cut off the biggest leaves first. These will be the leaves closest to the plant’s base. For each harvesting session, only take off a few outermost leaves. This will allow the plant to continue growing and producing more leaves.

When harvesting the kale, you’ll want to use scissors or a sharp knife to avoid damaging the plant. Think of it as cutting hair; you don’t want to hack away your kale! You can also choose to pull off the leaves. However, this may be a bit more challenging and time-consuming.

Once your kale is harvested, rinse it off and store it in airtight containers. To maximize its freshness and shelf life, keep it in the refrigerator. Kale is an excellent ingredient for salads, smoothies, and other dishes. Enjoy!


Growing kale can be a rewarding addition to any home gardener’s garden. Not only does it provide a nutritious boost to your diet, but it is low maintenance and easy to grow. You can enjoy a successful kale harvest by selecting the best location, variety, and soil, providing adequate and consistent care, and monitoring for pests and diseases. With these guidelines, you can confidently create a kale garden and reap the rewards of your efforts. So, why not give it a try? Grow some kale and enjoy the delicious, nutritious results.
