How to Grow Spinach

How to Grow Spinach

Spinach is a fantastic addition to any backyard garden. This nutrient-packed leafy green is versatile in the kitchen, quick to grow, and thrives in cool weather. Whether you’re looking to toss it in a salad, blend it into smoothies, or sauté it as a side dish, growing your own spinach is simple with the right approach. Here’s a step-by-step guide to help beginners grow a successful spinach crop.

Choosing the Right Spinach Variety

There are several different types of spinach, each suited to different conditions and uses. The two main types are:

  • Smooth-leaf spinach: These have flat, tender leaves that are easy to clean and perfect for salads.
  • Savoy spinach: With crinkly, thick leaves, this type is more robust and excellent for cooking.

For beginners, opt for fast-growing, bolt-resistant varieties like ‘Bloomsdale’ or ‘Space’, especially if you’re planting in a warmer climate. It's also important to note that some varieties are more cold-tolerant than others. While spinach is generally one the most cold-tolerant greens you can grow, some varieties are better suited for winter production.

When to Plant Spinach

Spinach thrives in cool weather and is best planted in early spring or fall. It prefers temperatures between 50°F and 70°F and can tolerate light frosts, making it an excellent crop for shoulder seasons.

  • Spring planting: Sow seeds as soon as the soil is workable, 4–6 weeks before the last frost.
  • Fall planting: Start seeds 4-6 weeks before your first expected frost date for a fall harvest.

One of the common mistakes that beginner gardeners make is planting spinach too soon in the fall. Spinach prefers soil temps in the 60s (°F) for high germination rates. Planting when the soil is still too hot can result in sub-optimal germination rates.

Prepping the Soil to Plant Spinach

Spinach needs nutrient-rich, well-drained soil to thrive. Here’s how to get your garden bed ready:

  • Choose the right location: Pick a spot that gets at least 4–6 hours of sunlight daily. While spinach prefers full sun, it can tolerate partial shade, especially in hotter climates.
  • Enrich the soil: Mix in compost if your soil doesn't drain well. Sprinkle Coop Gro organic fertilizer over the bed or row to provide a slow-release of nutrients to your spinach plants.
  • Loosen the soil: Use a garden fork or tiller to break up clumps and create a smooth surface for planting.

How to Plant Spinach


How to Plant Spinach

Spinach is typically grown from seeds because it germinates quickly. Follow these steps for planting:

  1. Sow the seeds: Plant seeds ½ inch deep and 2 inches apart in rows spaced about 12 inches apart.
  2. Water gently: Keep the soil consistently moist but not waterlogged to encourage germination. This can take 5–10 days.
  3. Thin seedlings: Once seedlings are a few inches tall, thin them to 4–6 inches apart to give plants room to grow.

For beginner gardeners, consider planting in succession every 2–3 weeks for a continuous harvest.

Watering and Feeding Spinach Plants

Spinach has shallow roots, so it needs regular watering, especially in dry weather. Here’s how to care for your spinach:

  • Water deeply: Provide about 1 inch of water per week, ensuring the soil stays moist but not soggy.
  • Fertilize frequently: Spinach is a heavy feeder. Apply Coop Gro organic fertilizer to the bed after each spinach harvest, or every 2-3 weeks as the plants grow. This will ensure the plants have all they need for continual production.

How to Protect Your Spinach

While spinach is relatively low-maintenance, it’s not immune to pests and problems. Here are some common issues and how to handle them:

  • Pests: Watch for aphids, slugs, and leaf miners. Use insecticidal soap, handpick slugs, or cover plants with row covers for protection.
  • Bolting: Spinach bolts (produces flowers and seeds) when temperatures climb. To delay bolting, plant bolt-resistant varieties, provide shade during hot afternoons, and keep the soil consistently moist.

When to Harvest Spinach

One of the best parts of growing spinach is harvesting your own fresh leaves. Spinach is ready to harvest about 6–8 weeks after planting, depending on the variety.

  • Pick young leaves: For tender spinach, pick individual leaves as soon as they’re large enough to eat, usually when they’re about 3–4 inches long.
  • Harvest the whole plant: For a larger harvest, cut the entire plant at the base. Leave about an inch of the stem intact. The leaves will grow back and provide another harvest in 3-4 weeks.

Harvest frequently to encourage new growth and prevent the leaves from becoming bitter.

Harvesting Spinach from the Garden


Enjoying Your Homegrown Spinach

Once you’ve harvested your spinach, rinse it thoroughly to remove any soil or pests. Fresh spinach can be stored in the refrigerator for up to a week, but it’s best used as soon as possible for maximum flavor and nutrients.

Growing spinach is a rewarding experience for gardeners of all levels. With these beginner-friendly tips, you’ll soon be enjoying fresh, nutritious greens right from your backyard. Happy gardening!
