So, read on to discover how to easily grow your own spinach at home and enjoy a year-round supply of this healthy vegetable.

1. Things You’ll Need to Grow Spinach

  • Plastic container/plant pot
  • Nutrient-rich soil
  • Fertilizer
  • Water
  • Spinach seeds
  • Other tools: Mini gardening tools, watering can, etc.

Materials needed for growing spinach

Tip: You can use regular soil from your garden for growing spinach. However, if this is your first time, it’s best to prepare one of these two types of soil:
– Mix river soil with worm castings in a 1:1 ratio
– Alternatively, mix Tribat soil with an organic substrate in a 1:1 ratio
Spinach thrives in slightly alkaline soil with a pH between 7.3 and 8.2. Sun-dry the soil for 5-10 days before planting to eliminate any potential pathogens.

Seed Selection: Look for heat-resistant F1 spinach seeds from reputable stores. Ensure the seeds are free from harmful chemicals and have a clear origin.

2. How to Grow Spinach

Step 1 Prepare the Seeds

Soak the seeds in warm water (40°C, or 2 parts boiling water to 3 parts cold water) for 3-4 hours to speed up germination. Then, rinse and wrap them in a damp cloth for about 8 hours until you see the seeds crack and sprout.

Step 2 Bottom Fertilization

Fill your plastic container or pot with the prepared soil and use your gardening tools to mix in the fertilizer thoroughly. Then, use your hands to smooth and level the soil.

Pro Tip: Leave a gap of 2-3 cm between the soil and the rim of the pot.

Step 3 Sowing the Seeds

There are two methods for sowing spinach seeds:

Method 1: Sparse Sowing

Plant the pre-soaked seeds about 6mm deep and space them about 5cm apart. Then, gently cover with soil and shade the area with straw or a sunshade net to maintain optimal moisture for germination.

Method 2: Dense Sowing

Scatter the seeds evenly across the soil without worrying about spacing. Then, place the pot in an area with moderate sunlight to maintain the right moisture level for germination.

3. Caring for Your Spinach Plants

Watering

Spinach loves moisture, so water your plants regularly. When the seeds are freshly sown, water twice a day, once in the early morning and once in the cool evening, to encourage germination.

Once the plants are established and growing vigorously, you can reduce watering to once or twice a day, adjusting as needed based on the weather.

Fertilizer Application

After about 10-15 days, when the seedlings have sprouted leaves and the roots are well-established, start weeding and hilling. At this point, you can apply a combination of worm castings and organic liquid fertilizers once a week for 4-5 weeks.

Hilling and applying fertilizer

If you’re growing your spinach in rows, you can apply dry fertilizer. Fertilize twice: once 20-25 days after planting and again 35-40 days after planting.

Pest Control

Keep an eye out for common pests like leaf-eating snails, aphids, worms, and flies.

Remove any pests you find and discard damaged leaves. To deter snails and slugs, try watering your plants with diluted vinegar to create an acidic environment that these pests dislike.

Tip: To prevent pests and diseases, you can also use a natural solution made by grinding garlic and chili peppers, straining the mixture, and then mixing it with rice water.

Thinning the Leaves

To encourage the growth of large, healthy leaves, thin out the spinach plants. If you sowed the seeds densely, leave about 10-15 cm between each plant. If you planted in rows, thin to one plant per hole.

Your spinach is ready to harvest when the plants have 5-7 leaves that are about 10-15 cm long.

Frequently asked questions

Spinach is a nutrient-dense vegetable that is easy to grow and provides a plentiful harvest. It can be grown year-round with proper care and is a great source of vitamins and minerals. Spinach is also versatile in the kitchen, used in salads, smoothies, and cooked dishes.

Spinach thrives in cool, moist conditions with partial sun to light shade. The ideal temperature range is 60-70°F (15-21°C). Ensure your soil is rich, well-drained, and slightly acidic, with a pH of 6.0 to 7.0. Amend the soil with compost or well-rotted manure before planting.

For a year-round supply, plant spinach in early spring, late summer, and early autumn. Sow seeds directly into the ground or start them indoors in trays. Space seeds 2-3 inches apart and cover lightly with soil. Keep the soil moist and thin the seedlings once they develop true leaves.

Water your spinach regularly, ensuring the soil doesn’t dry out. Apply a balanced fertilizer every 2-3 weeks during the growing season. Keep an eye out for common pests like aphids and caterpillars, and control them with natural methods like insecticidal soap or neem oil.

You can start harvesting spinach leaves once they are large enough to eat, typically around 4-6 weeks after planting. For a cut-and-come-again crop, use scissors to cut the outer leaves, leaving the inner leaves to continue growing. For a full harvest, cut the entire plant about an inch above the soil, and it may regrow.

Harvested spinach can be stored in the refrigerator for up to a week. Blanch and freeze spinach for longer-term storage. Spinach is a nutritional powerhouse, packed with vitamins A, C, and K, as well as iron, calcium, and antioxidants. It’s a great way to boost your daily intake of essential nutrients.
