Soil facts and preparation

Quick facts..

  • Soil Type Fertile and Well Drained
  • Ideal Ph range 6.5 to 7.5
  • Site Full Sun
Well drained, moisture retaining soil containing plenty of organic matter is required to grow spinach. Pick a spot in full sun for winter varieties or partial shade for summer.

Dig in plenty of well rotted manure or fresh compost and remove any large stones. Rake in a general purpose fertilizer a couple of weeks before sowing or planting. Spinach is also suitable for growing in large pots or containers filled with fresh compost.

Sowing and planting

Quick facts..

  • Germination 6 to 10 days
  • Sow 25mm deep
  • Sow Spacing 75mm
  • Rows 400mm apart
For a constant supply of spinach make successive sowings every 1 or 2 weeks. Sow winter varieties 2.5cm deep and summer varieties 1cm deep and 5cm apart in rows with 30cm between them. Germination rates deteriorate as soil temperatures rise so sow more seed closer together as the weather warms. Spinach seedlings do not transplant well so sow directly if possible. Thin weaker seedlings to leave 25cm between plants.

Growing a bumper crop

Keep the area between plants weed free. Spinach has a shallow root system and needs constant moisture to maintain succulent leaves. Mulching when the plants are well established will help the soil retain moisture and help suppress weeds. Periods of drought can cause spinach to bolt and leaves to taste bitter.

For the best results apply a high nitrogen fertiliser. Nitrogen promotes foliage growth and is therefore best suited to the vegetables where it is leaves that are harvested.

Harvesting the fruits of your labour

Quick facts..

  • Yield 250g per plant
Pick leaves regularly from the outside of the plant. Picking a little often will encourage the plant to produce new leaves for harvesting later. For the best possible flavour and nutritional value, spinach should be eaten as soon after picking as possible.
