Collards are an under-rated green, that are high in vitamins and minerals, but are low in flavor.  The large, paddle-shaped leaves, can be harvested over an extended period when they are picked from the bottom up, as they mature. Plants can grow up to three feet tall, and will produce new leaves for several years before they go into their bloom mode.  The flavor of the leaves is sweeter when the weather is colder, frost actually enhances the flavor.  When transplanting, add two handfuls of compost, one handful of landscape mix and one of worm castings to the hole.  Yield is greater when each plant is given 18- 24” of space.
