Why July is Perfect for Planting Perpetual Spinach in the UK

July offers ideal conditions for establishing perpetual spinach in UK gardens. The warm soil temperatures, typically ranging from 15-20°C, provide optimal germination conditions whilst still allowing plenty of growing time before winter sets in.

Unlike true spinach (Spinacia oleracea), perpetual spinach is actually a type of leaf beet or chard that doesn't bolt in hot weather. This makes July planting particularly successful because:

• Reliable germination: Seeds germinate consistently in 7-14 days when soil temperatures reach 16-18°C
• Extended growing season: Plants established in July have 12-16 weeks to develop strong root systems before winter
• No bolting issues: Unlike annual spinach, perpetual spinach thrives in warm July conditions
• Continuous harvests: July plantings provide fresh leaves from September through the following spring

The long daylight hours of July also promote vigorous leaf growth, whilst the established plants will easily survive UK winters with minimal protection. This timing ensures you'll have fresh greens when shop-bought alternatives are most expensive.

Soil Preparation and Site Selection

Success with perpetual spinach begins with proper soil preparation. This adaptable crop tolerates various soil types but thrives in well-prepared, fertile ground.

Soil Requirements

Perpetual spinach prefers:

• Well-drained soil: Avoid waterlogged conditions that can cause root rot
• pH level: Neutral to slightly alkaline (6.0-7.5) - avoid very acidic soils
• Rich organic content: High in organic matter for sustained nutrition
• Moisture retention: Holds water well but doesn't become waterlogged

Site Selection

Choose a location that receives:

• Full sun to partial shade: 6-8 hours of sunlight daily, though it benefits from afternoon shade in hot weather
• Good air circulation: Prevents fungal diseases whilst avoiding windy spots
• Easy access: For regular harvesting and maintenance

Soil Preparation Steps

Begin preparation 2-3 weeks before sowing:

1. Clear the area: Remove weeds, stones, and debris
2. Dig or fork: Work the soil to 20-25cm depth
3. Add organic matter: Incorporate 2-3 inches of well-rotted compost or manure
4. Rake level: Create a fine, even surface for sowing
5. Water thoroughly: Ensure soil is moist but not waterlogged

If your soil is heavy clay, consider creating raised beds or adding coarse sand and organic matter to improve drainage. Poor soils can be enhanced with a balanced organic fertiliser raked in before sowing.

Sowing Perpetual Spinach Seeds in July

July sowing of perpetual spinach seeds is straightforward and highly successful when you follow proper techniques. The warm soil conditions ensure quick germination and strong establishment.

Seed Characteristics

Perpetual spinach seeds are distinctive:

• Large and corky: Each 'seed' is actually a cluster containing 3-5 individual seeds
• Irregular shape: Rough, wrinkled appearance that's perfectly normal
• Good viability: Fresh seeds typically show 70-80% germination rates

Direct Sowing Method

Follow these steps for successful July sowing:

1. Create shallow drills: Make furrows 1.5-2cm deep using a hoe or finger
2. Space rows correctly: Allow 30-40cm between rows for easy access
3. Sow seeds: Place seeds 5-10cm apart along the drill
4. Cover lightly: Backfill with soil and firm gently
5. Water carefully: Use a fine rose to avoid washing away seeds
6. Mark rows: Use labels to identify sowing areas

Alternative Sowing Methods

Station sowing: Sow 2-3 seeds every 20cm, thinning to the strongest seedling later. This reduces the need for extensive thinning.

Module sowing: Start seeds in 7-9cm modules filled with seed compost, sowing one seed per module. Transplant after 4-5 weeks when plants are 5-7cm tall.

Germination Expectations

In July's warm conditions, expect:

• Germination time: 7-14 days (up to 21 days in cooler periods)
• Temperature needs: Soil temperature of 16-18°C for best results
• Emergence rate: 70-80% with fresh seeds

Remember that germination may be slower if temperatures exceed 25°C, so consider sowing in a partially shaded area during particularly hot spells.

Watering and Early Care

Proper watering and early care are crucial for establishing healthy perpetual spinach plants from July sowings. Consistent moisture and appropriate maintenance ensure strong growth and continuous harvests.

Watering Guidelines

Initial watering: Water gently immediately after sowing using a fine rose attachment to avoid displacing seeds. The soil should be moist but not waterlogged.

Germination period: Maintain consistent moisture during the 7-14 day germination period. Check daily and water lightly if the surface appears dry.

Established plants: Once seedlings emerge, water deeply but less frequently to encourage deep root development. Aim for 2-3cm of water per week.

Watering Best Practices

• Water at soil level: Avoid watering leaves to prevent fungal diseases
• Early morning watering: Reduces evaporation and allows plants to dry before evening
• Consistent moisture: Avoid alternating between dry and soggy conditions
• Mulching: Apply organic mulch around plants to retain moisture and suppress weeds

Thinning Seedlings

Begin thinning when seedlings reach 3-5cm tall:

1. First thinning: Remove weaker seedlings from each cluster, leaving the strongest
2. Second thinning: Thin to 15-20cm apart for full-sized plants
3. Use thinnings: Young leaves make excellent additions to salads
4. Careful technique: Pinch or cut rather than pull to avoid disturbing remaining plants

Protection and Support

Bird protection: Cover young plants with fine netting or fleece to prevent pigeon damage. Remove once plants are established (6-8 weeks).

Pest monitoring: Watch for aphids and leaf miners, particularly during warm weather. Remove affected leaves promptly.

Feeding Requirements

Perpetual spinach benefits from regular feeding:

• Liquid fertiliser: Apply nitrogen-rich liquid feed every 2-3 weeks
• Organic options: Use comfrey tea or diluted seaweed extract
• Avoid over-feeding: Excessive nitrogen can reduce flavour and increase pest problems

For optimal growth and continuous harvests, consider supplementing with Levington Tomorite Liquid Tomato Feed, which provides excellent nutrition for leafy crops.

Harvesting Your July-Planted Perpetual Spinach

One of the greatest advantages of July-planted perpetual spinach is the extended harvesting season. Plants established in July will provide fresh leaves from September through the following spring, offering exceptional value from a single sowing.

When to Start Harvesting

Begin harvesting when plants are well-established:

• Baby leaves: 4-6 weeks after germination (late August/early September)
• Mature leaves: 8-12 weeks after sowing (September/October)
• Continuous harvest: Pick regularly from September through to May

Harvesting Techniques

Cut-and-come-again method: The key to continuous harvests is proper picking technique:

1. Select outer leaves: Always harvest the largest, outer leaves first
2. Leave the crown: Never cut the central growing point
3. Twist and pull: Gently twist leaves at the base and pull cleanly away
4. Regular picking: Harvest every 7-10 days to encourage new growth

Seasonal Harvesting Guide

September-October: Peak harvest time with tender, flavourful leaves. Pick generously as plants are actively growing.

November-December: Continued harvests but slower growth. Pick more selectively to maintain plant vigour.

January-March: Minimal harvesting during coldest months. Pick only what's needed and protect plants with fleece if necessary.

April-May: Renewed vigorous growth as temperatures rise. Resume regular harvesting before plants eventually bolt.

Harvest Quantities

Expect impressive yields from July plantings:

• Per plant: 0.5-1kg of leaves over the growing season
• Small family: 4-6 plants provide adequate fresh spinach
• Continuous supply: Harvest 50-100g per plant per week during peak season

Storage and Preservation

Fresh storage: Store unwashed leaves in plastic bags in the refrigerator for up to 5 days.

Freezing: Blanch leaves for 2 minutes, cool quickly, and freeze in portions for winter use.

Drying: Air-dry leaves for winter seasoning, though fresh is always preferable.

Signs of Quality
