collard plant flowering
I put collard plants out 4 weeks ago and now have flowers. How should I prune the plants to produce more greens? The plants are now 14 to 18 inches tall and producing flowers.
When collards produce flowers it is called "bolting." You should cut off the flower stalks as soon as they appear, to keep the plant producing leaves. This article will give you more information: https://www.gardeningknowhow.com/edible/vegetables/greens/growing-collard-greens.htm
