Fish emulsion: This liquid fertilizer is high in nitrogen, which promotes leafy growth. Dilute fish emulsion according to package instructions and apply every 2-3 weeks.
Cottonseed meal: Rich in nitrogen and also provides other essential nutrients. Apply cottonseed meal to the soil before planting and mix it thoroughly with the soil.

Soy meal: Another good source of nitrogen and can be used as an alternative to cottonseed meal. Mix it into the soil before planting.

Frequency of Fertilization

Proper fertilization is crucial for growing spinach in containers, and it is important to strike a balance between providing adequate nutrition without over-fertilizing. Here’s a guideline for fertilization frequency:

Initial soil preparation: Mix a slow-releasing organic fertilizer, such as cottonseed or soy meal, into the soil before planting the seeds. This ensures the spinach has a good nutrient foundation to start with.

During growth: Fertilize spinach every 2-3 weeks with a liquid fertilizer, such as fish emulsion, to provide a steady supply of nitrogen and other essential nutrients. Be sure to follow package instructions for proper dilution rates.
Adjusting pH and iron levels: Spinach prefers a soil pH between 6.0 and 7.0, and an imbalance in pH can affect nutrient uptake. Test the soil pH periodically and adjust it, if needed, with appropriate amendments like lime or sulfur. Spinach also requires adequate iron levels to prevent yellowing leaves; if you notice this issue, consider using an iron chelate fertilizer according to package recommendations.

Following these fertilization tips, you can ensure that your container-grown spinach receives the necessary nutrients for optimal growth and a bountiful harvest.

Harvesting and Storing Spinach

When to Harvest

Spinach leaves are typically ready for harvest 40 to 45 days after sowing. It’s best to harvest when the plant has at least five or six leaves. You can harvest baby spinach leaves when they reach 3-4 inches in height or wait for mature leaves to grow larger.

How to Harvest

To harvest spinach, you can either use scissors or just pinch off the outer leaves with your fingers, taking care not to damage the main stem. By only harvesting the outer leaves and allowing the center of the plant to continue growing, you can enjoy multiple harvests from the same plant.

Baby spinach: Harvest when leaves reach 3-4 inches in height.

Mature spinach: Harvest when leaves are at their desired size.
Method: Use scissors or pinch off outer leaves with fingers.

Storing Spinach

After harvesting, spinach can be stored in several ways to prolong its freshness:

Refrigerate: Gently wash the spinach leaves, pat them dry with a clean towel, and place them in a plastic bag or container with a paper towel to absorb excess moisture. Store in the refrigerator for up to one week.
Freeze: Blanch the spinach leaves briefly in boiling water, then transfer them to an ice water bath to stop the cooking process. Once cooled, pat dry and store in freezer-safe bags or containers for up to 3 months.
