Description

Spinach English Winter Giant most probably originates from 1866 France, despite it’s commonly used name. It has large, semi-savoyed green leaves and is a cool hardy variety making it an excellent selection for autumn, winter and early spring. The leaves have a fine flavour and are tender and can grow to the size of Swiss chard leaves.

It has a rich, bold flavour that intensifies the longer the leaves are left on the plant.  Great raw in salads when young as baby leaf and also excellent when used as a cooked green vegetable in curries, soups and casseroles when older.  This variety is lower in oxalic acid than most spinach varieties.

Soil Preparation 

 pH:

  • 6.0–7.0 test soil and adjust with lime or sulphur if needed. 

 Texture:

  • Well drained, loamy soil enriched with compost or aged manure. 

 Drainage:

  • Raised beds or mounds in heavy soils to prevent waterlogging. 

Planting Seeds 

 Depth:

  • 1 cm deep. 

 Spacing:

  • 15 cm between plants, 30 cm between rows. 
  • Succession Planting: Sow every 2–3 weeks for continuous harvest. 

 Germination Tips:

  • Soak seeds 12–24 hours before planting to improve germination.
  • Use shade cloth or mulch in warmer areas to keep soil cool. 

Watering 

  • Keep soil consistently moist but not soggy. 
  • Water deeply 2–3 times weekly; mulch with straw or sugar cane to retain moisture. 
  • Avoid overhead watering to reduce disease risk. 

Fertilising 

  • Apply balanced fertiliser at planting. 
  • Side dress with a nitrogen rich fertiliser 4 weeks after germination. 
  • Avoid over fertilising to prevent bolting. 

Pest & Disease Management 

 Pests: 

  • Aphids – Spray with soapy water or neem oil. 
  • Slugs/Snails – Use beer traps or diatomaceous earth. 
  • Flea Beetles – Protect with row covers; plant radishes as trap crops. 

 Diseases: 

  • Downy Mildew – Ensure good airflow, use copper based fungicides. 
  • Spinach Blight – Remove infected plants, control aphids. 

Harvesting 

  • Begin harvesting outer leaves when 10–15 cm long (6–8 weeks). 
  • Pick in the morning for crispness; avoid damaging the crown. 
  • Regular harvesting delays bolting.
  • If bolting occurs, collect seeds or replace plants. 

Companion Planting Guide 

 Good Companions: 

  • Beans/Peas – Fix nitrogen in soil. 
  • Strawberries – Low growing, noncompetitive. 
  • Radishes – Deter leaf miners, act as trap crops. 
  • Lettuce/Cabbage – Share similar growing conditions. 
  • Marigolds/Nasturtiums: Repel pests like aphids and nematodes. 

 Avoid Planting With: 

  • Potatoes – Compete for nutrients. 
  • Fennel – Allelopathic; inhibits growth. 

Troubleshooting 

 Bolting:

  • Caused by heat/long days.
  • Use bolt resistant varieties (e.g., ‘Perpetual Spinach’) and shade cloth. 

 Yellow Leaves:

  • Overwatering or nitrogen deficiency.
  • Adjust watering and fertilise. 

Container Growing 

  • Use pots 20–30 cm deep with drainage holes. 
  • Keep in partial shade during summer. 

Crop Rotation 

  • Avoid planting after beets or chard (same family).
  • Rotate with legumes or brassicas.
