Collards are such a long season crop, they are usually direct sown 20 to 30" apart in mid spring. Wait until the cold weather has passed, so there is no chance of them being vernalized (which could cause them to bolt). Though Collards are most tender and better flavored when grown in cool weather, they do tolerate heat.
- Outdoor Growing Temp
- 40°F - 80°F
- Min Outdoor Soil Temp
Collards are pretty hardy and can go into the ground when it is still fairly cold. However they will germinate and grow faster in warmer soil.
- Start Indoors
- Start Outdoors
- Sun: min. 6 hours daily (Cold, Cool, Warm, Hot)
Collards will be most productive in full sun, though they will tolerate partial shade.
Collards must have plenty of water for maximum productivity and best quality.
Low nitrogen. Moderate potassium. Moderate phosphorous.
Collards have similar nutritional requirements as kale, in that it needs a significant amount of phosphorus and potassium, but not a lot of nitrogen. It will flower early with too much nitrogen.

- Small Gardens?
Collards grow larger than most greens, so you will need a container that is a minimum of 12" in diameter and 12 to 18" deep for one plant. Make sure that your container has drainage holes, and line the bottom with weed cloth or rocks/gravel. Cover with a mixture of potting soil and compost. Collards love sunshine, so make sure to place your container in an area that has access to sun all day. You will need to water once a day in hot climates and less frequently when the weather is cool.
