Leafy greens pack a nutritional punch and are an ideal crop for both newbie and experienced gardeners. They sprout quickly, require minimal care, and are extremely economical, as most seed packets contain enough seeds for several plantings, even into next season.
That brings up the next topic: Many greens have a short time to harvest, which allows for multiple succession plantings and nutritious, crunchy goodness year-round. Change up the selection periodically to keep your taste buds tantalized.
