• Soil: Spinach prefers well-drained, fertile soil with a pH between 6.0 and 7.0. Amend the soil with compost or well-rotted manure to improve fertility and structure.

• Sun: Full sun to partial shade is ideal for spinach. In warmer climates, some afternoon shade can help prevent bolting.

• Watering: Keep the soil consistently moist but not waterlogged. Mulching helps retain soil moisture and regulate temperature.

• Spacing: Plant spinach seeds 1/2 inch deep, spacing them 2-6 inches apart and in rows 12 inches apart. Thin seedlings to allow adequate room for growth.

• Fertilization:
  N-P-K Ratio: Spinach benefits from a fertilizer with a higher nitrogen content to support leafy growth, such as 16-16-8 or 20-10-10.

  When to Add:

  • Before Planting: Apply the fertilizer to the soil before planting seeds or transplants to promote strong initial growth.

  • Mid-Growing Season: Reapply the fertilizer every 3-4 weeks during the growing season to support continued leafy growth.

  Application Tips:

  • Follow the directions on the fertilizer package to avoid over-fertilization.

  • Apply the fertilizer evenly around the base of the plants and water thoroughly to help the nutrients reach the roots.

  Additional Tips:

  • Spinach grows best in well-drained soil rich in organic matter, so consider adding compost to improve soil fertility and structure.

  • Mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature.

  • Ensure that spinach receives consistent moisture to prevent stress and promote tender, flavorful leaves.
