how late can i plant collard greens

Question

The worms ate the plant and I need to plant more.

Answer 1

The date you can plant collards is determined both by your location, and the variety you have. Some cold weather is actually good for collards. Check the seed package and count the days till harvest that it lists. This article has more information: https://www.gardeningknowhow.com/edible/vegetables/greens/growing-collard-greens.htm
