Soil Preparation

Spinach thrives in well-drained, fertile soil with a pH between 6.0 and 7.0. To prepare the soil:

Testing Soil: Conduct a soil test to determine nutrient levels and pH.

Amending Soil: Add organic matter such as compost to improve soil structure and fertility.

Tilling: Till the soil to a depth of 6-8 inches to ensure good root penetration and drainage.

Seed Selection and Sowing

Variety Selection: Choose spinach varieties suited to your climate and intended use (e.g., baby spinach, savoy, or flat-leaf). Popular varieties include ‘Bloomsdale’, ‘Tyee’, and ‘Space’.

Direct Sowing: Sow seeds directly into the garden as soon as the soil can be worked in early spring or late summer for a fall crop.

Succession Planting: To ensure a continuous harvest, plant spinach seeds every two weeks throughout the growing season.

Planting

Spacing: Space plants 4-6 inches apart in rows 12-18 inches apart to allow adequate air circulation and room for growth.

Planting Depth: Plant seeds about 1/2 inch deep.

Watering

Consistent Moisture: Keep the soil consistently moist, as spinach has shallow roots and is sensitive to water stress. Spinach requires about 1 inch of water per week.

Mulching: Apply mulch around the plants to retain moisture, regulate soil temperature, and reduce weed growth.

Fertilization

Initial Fertilization: Incorporate a balanced, all-purpose fertilizer into the soil at planting time.

Ongoing Feeding: Side-dress with a nitrogen-rich fertilizer every few weeks to promote leafy growth.

Pest and Disease Management

Common Pests: Watch for aphids, leaf miners, and spider mites. Use organic insecticides or introduce beneficial insects to control pest populations.

Diseases: Monitor for signs of downy mildew, leaf spot, and other fungal diseases. Practice crop rotation and ensure good air circulation to minimize risk.

Harvesting

Timing: Harvest spinach when the leaves are full size but still young and tender. You can harvest outer leaves as needed or cut the whole plant at the base.

Handling: Handle spinach gently to avoid bruising and damage. Harvest in the morning when leaves are crispest.

Benefits of Growing Spinach

Nutritional Value: Spinach is rich in vitamins A, C, and K, as well as iron, calcium, and antioxidants.
