How to Grow Spinach: Step-by-Step

1. Prepare the Soil

• Location: Choose a site with partial shade or full sun during cooler months.
• Soil Type: Spinach prefers well-draining, fertile soil enriched with compost or well-rotted manure.
• pH: Aim for a neutral to slightly acidic soil pH (6.0–7.5).

2. Sow the Seeds

• Sow seeds 1cm deep and 2.5–5cm apart in rows spaced 30cm apart.
• Cover lightly with soil and water gently to settle the seeds.

3. Germination

• Spinach seeds germinate in 7–10 days in temperatures between 7–21°C.

4. Thin the Seedlings

• Once seedlings are 2–3cm tall, thin them to 10–15cm apart to allow space for growth.

Caring for Spinach Plants

1. Watering
   • Keep the soil consistently moist, especially during dry spells. Water at the base of the plant to avoid wetting the leaves.
2. Mulching
   • Apply a layer of mulch to retain soil moisture and suppress weeds.
3. Fertilizing
   • Use a nitrogen-rich fertilizer every 2–3 weeks to encourage leafy growth.
4. Weeding
   • Regularly remove weeds to reduce competition for nutrients and water.
5. Shade During Heat
   • Use shade cloth during hot weather to prevent bolting (premature flowering).

Harvesting Spinach

1. When to Harvest
   • Spinach is ready for baby leaves in 30–40 days or mature leaves in 40–50 days.
2. How to Harvest
   • Pick the outer leaves first, leaving the inner leaves to grow for continuous harvesting.
   • Alternatively, cut the entire plant at the base for a one-time harvest.
3. Storage
   • Store fresh spinach in the refrigerator for up to a week, or blanch and freeze for long-term storage.

Common Problems and Solutions

1. Bolting
   • Cause: Hot weather or lack of water.
   • Solution: Provide consistent moisture and shade during heatwaves.
2. Yellowing Leaves
   • Cause: Nitrogen deficiency.
