Preparing the Soil

Spinach and chard are easy-going but perform best in fertile, well-drained soil.

3. Add compost or well-rotted manure – Improves soil fertility and moisture retention.
4. Rake soil to a fine tilth – Ideal for seed germination.

Caring for Spinach and Chard Through Autumn and Winter

Watering

• Water regularly during dry autumn spells.
• Reduce watering in winter, as soil stays moist.

Feeding

• Apply a balanced fertiliser every 4–6 weeks.
• Mulch around plants with compost or leaf mould for slow-release nutrients.

Protection

• Use fleece, cloches, or polytunnels in harsh winters.
• Protect from slugs with barriers or organic pellets.

Weeding

Harvesting Spinach and Chard

Spinach

• Start harvesting young leaves 6–8 weeks after sowing.
• Pick outer leaves regularly to encourage regrowth.
• Harvest little and often for continuous supply.

Chard

• Pick young leaves for salads or larger leaves for cooking.
• Harvest outer leaves first; plants keep producing for months.
• Rainbow chard is both ornamental and edible.

Common Problems and Solutions

• Slugs and Snails – Use organic pellets, beer traps, or barriers.
• Downy Mildew (Spinach) – Provide good spacing for airflow and avoid overhead watering.
• Bolting – Less common in autumn; choose bolt-resistant varieties.
• Bird Damage – Cover crops with fleece or netting if birds peck leaves.

---

Companion Planting Ideas

• Grow spinach alongside garlic and onions to deter pests.
• Chard pairs well with brassicas, as it doesn’t compete heavily for nutrients.
• Avoid planting near potatoes, which can crowd out spinach.

---

Storing and Using Spinach and Chard

• Both crops are best eaten fresh.
• Store in the fridge for up to 5 days.
• Blanch and freeze surplus spinach or chard for soups and stews.
• Use raw in salads, cooked in stir-fries, or as a side vegetable.
