3 Plants NOT Suitable for Planting with Spinach

While there’s a wide range of companion plants for spinach, some plants should be kept at a distance due to various incompatibilities. Here’s a list of plants that aren’t the best companions for spinach:

1. Potatoes

Potatoes can compete with spinach for nutrients and space. Additionally, planting them together can increase the risk of diseases common to both, like early blight.

2. Sunflowers

Sunflowers should not be planted with spinach.

Sunflowers can cast dense shade over smaller plants, including spinach, hindering their growth—plant sunflowers in a separate area of your garden to avoid shading your spinach.

3. Fennel

Fennel has allelopathic properties, which means it releases chemical compounds that can inhibit the growth of nearby plants.

Therefore, it’s best not to plant fennel near spinach because fennel can prevent spinach from growing well.

Fennel also attracts pests that can harm your spinach. So, keep fennel and spinach in different areas of your garden to avoid these issues.

12 Tips for Growing Healthy and Vibrant Spinach

The following tips can help your spinach thrive:

1. Choose the Right Variety

Select a spinach variety that suits your climate and growing conditions. Some varieties are better suited for cool weather, while others are more heat-tolerant.

2. Timing is Key

Spinach is a cool-season crop, so timing is crucial. Plant spinach in early spring or late summer for the best results. You should grow spinach as a fall crop in warmer climates to avoid extreme heat.

3. Soil Preparation

Spinach thrives in well-draining, fertile soil with a pH level between 6.0 and 7.0. Amend your soil with compost or well-rotted manure for better texture and nutrient content.

4. Spacing and Planting Depth

Sow spinach seeds about 1/2 inch deep and 2 inches apart in rows spaced 12 inches apart. Proper spacing prevents overcrowding and encourages air circulation, reducing the risk of diseases.

5. Watering

Keep the soil consistently moist but not soggy. Spinach doesn’t tolerate drought well. Use mulch to help retain moisture and reduce the need for frequent watering.

6. Fertilization

Fertilize with a balanced, all-purpose fertilizer before planting or using compost during the growing season. Be cautious not to over-fertilize because this can lead to excessive leafy growth and less flavorful leaves.

7. Thinning Seedlings

When spinach seedlings are about 2 inches tall, thin them to ensure proper spacing. This allows the remaining plants to grow vigorously and produce larger leaves.

8. Pest and Disease Management

Be vigilant for common pests like aphids, snails, and slugs. Handpick pests and use organic pest control methods like neem oil or diatomaceous earth. Avoid overhead watering and ensure good air circulation to prevent diseases like downy mildew.

9. Harvesting

Spinach is best when harvested young and tender. Begin harvesting outer leaves when they reach a usable size, usually around 4-6 inches in length. Use a sharp knife or scissors to cut the leaves, leaving the center intact for continued growth.

10. Successive Planting

To enjoy a continuous spinach harvest, sow new seeds every few weeks. This ensures a fresh supply of leaves throughout the growing season.

11. Protect from Extreme Temperatures

Provide shade for your spinach plants in very hot weather using a shade cloth. Use row covers to extend the growing season into the fall in cold climates.

12. Store Properly

After harvesting, store spinach leaves in the refrigerator. Place them in a plastic bag or container with a damp paper towel to maintain freshness.

Following these gardening tips, you can cultivate a thriving spinach patch that yields delicious, nutritious greens throughout the growing season.
