Collard Greens: How to Grow and When to Plant in Your Backyard or Patio Garden!

Collard Greens blog post
Collard greens are one of the rare leafy greens that can tolerate both hot and cold temperatures. Long after our kale, spinach, and lettuce have bolted to seed, the collard greens will still be going strong! They are also more pest-resistant than the other members of the brassicaceae family.

How to Grow:

Collard greens are a cool season crop that is planted 4-6 weeks before your last spring frost and 10 weeks before your first fall frost. You can see specific dates for your location using our FREE iOS, Android, and Universal Web App.

Collard greens are planted 1/4 inch deep, 1 per square foot, in the full sun. Take care to notice what plants are around the area as well, see the companion plant section below. Collard greens sprout between 4-10 days and require moderate and consistent watering.

Companion Plants:

Companion planting is a vital part of organic gardening. Companion plants assist in the growth of others by attracting beneficial insects, repelling pests, or providing nutrients, shade, or support. There are also plants that do not like being next to each other. Some plants get too tall and can provide too much shade for your plant. Sometimes certain plants attract the same pests, so it is important to try and separate these.

Collard greens are ready to harvest within 50-60 days. You can start to harvest leaves when they are 10 inches long. Pick the leaves on the outside first, and work your way to the inner.

Cooking & Eating!

Soak collard leaves in ice cold water to help remove any bugs that may have remained and to increase preservability. Use immediately or store in the refrigerator in a ziplock bag with a damp paper towel. Extra leaves may be frozen for long-term storage. Our favorite way to use collards is in our stir-fries.

  1. This is a vegetable that is still very uncommon here, although it was and likely still is popular in the Watts Neighborhood of Los Angles when I was doing my internships in 1988. Small plants were house warming gifts for those who moved into a new home. In the mild climate, they were grown as perennials that lasted for many years. As they got too big and overgrown, their sideshoots could be layered to develop into new plants.
