spinach · Spinacia oleracea
Also known as: common garden spinach; winter spinach
Spinach is a leafy green vegetable that thrives in cool weather and well-drained fertile soil. It requires consistent watering to maintain moist soil, particularly during the germination and early growth stages. Overcrowding must be avoided to ensure healthy growth by thinning seedlings early. Notably, spinach is prone to bolting in hot temperatures, so providing shade can extend the harvest period. The care for spinach is generally considered easy due to its rapid growth and minimal maintenance requirements.
For spinach, apply a high-nitrogen fertilizer to promote vigorous leaf growth, crucial for a fruitful harvest. Fertilize young plants every 2 weeks and mature ones monthly, using 1 tablespoon per plant. During peak growing season, adjust frequency based on plant response. Avoid over-fertilization to prevent root burn. Incorporate organic compost for improved soil health. Water spinach post-fertilization to help nutrient absorption.
