Everything You Need To Know About Growing Collard Greens

Collard Greens

Collard greens are a cool-weather crop that is native to the Eastern Mediterranean region and are now cultivated throughout the world.

PLANTING COLLARD GREENS

Collards are best grown in full sun with well-drained soil and a soil pH range of 6.0 through 6.5.

They can be sown straight into the soil after the last frost or started 8 to 10 weeks before the last frost indoors using a cardboard seed starting tray.

They are best planted 36 to 42 inches apart for rows, 15 to 18 inches apart, and one-half of an inch to one inch deep.

For best results, it is recommended before planting or sowing them to till compost into the soil which is known as amending the soil.

This will provide nutrients to the soil, helps with water retention, and will help to keep the soil loose which will make it easier for the roots to grow.

FERTILIZING AND WATERING

To avoid any possible issues of over-fertilizing your collards, you should test your soil before adding any fertilizers.

Collard greens are best fertilized every two weeks with a balanced fertilizer such as 10-10-10 or a homemade liquid fertilizer can be used.

They prefer soil that is consistently moist but not soaked and they will require about 1 to 2 inches of water per week.

HARVESTING

Collards are best harvested when they are young and about ten inches long.

The whole plant can be removed or some of the leaves of each plant can be harvested for continued harvesting.

Harvesting can be done by removing the large outer leaves with sterilized pair of gardening shears or a gardening knife above the crown of the plant.

PROPAGATING

Collard greens are propagated through seed, therefore some plants should be allowed to go to seed for the following season.

PESTS

Collard greens have many pests that feed on them but using natural methods such as attracting predators and using natural insecticides such as essential oils, diatomaceous earth, or insecticidal soap will keep your pest control organic.

Joel Simon

As a kid, Joel found enjoyment in caring for the many houseplants he grew up with, learning how to transplant them safely, cloning them, and more. At about the age of 10, he wanted to see if he could sprout an orange seed from a store-bought orange and ended up using it as a science experiment in a school project. Throughout the many years of gardening, he has helped many friends and family set up their food and botanical gardens. After years of caring for plants, he was talking with other gardeners and discovering old methods of farming and botanical gardening. Joel has decided to share his knowledge for others to enjoy as he has for many years.
