Spinach
Spinacia oleracea
Spinach contains oxalic acid that binds calcium and iron — pairing it with vitamin-C-rich foods (citrus, peppers) increases iron absorption by up to 3×, debunking the Popeye myth that raw spinach alone is an iron powerhouse.
How to care for spinach
Sow as soon as soil works in spring — bolts hard at 75°F. Direct-sow only (transplants set back); succession every 2 weeks. Use floating row cover to defeat leaf miners. Choose 'Bloomsdale' or 'Tyee' for slow-bolt resistance.
