Spinach
This plant prefers rich soil with plenty of moisture to help it grow fast. Sow seeds in well-prepared soil and thin them out. Don’t throw the baby spinach plants away though, as they can be used in salads. You can harvest the entire plant after 45 days, or you can keep plucking leaves all through the season.
A long-lasting persistent myth is that spinach contains significantly more iron than other green vegetables.
