Am posting some instructions and tips for growing spinach, as we have been sowing a lot of spinach seeds. Will be posting compiled information for all the vegetables we are growing, for the reference of the team as well as others who are interested. Will modify this as we learn more about the process.
The info has been collected from a range of websites. Relevant credits and links are given at the end.
- Choose a site that gets full sun in cool weather and partial shade in warmer temperatures.
- Soil should be light, fertile and moisture-retentive, with a pH of 6.0 to 7.0.
- Germination of spinach seeds can take anything between a week and 2 weeks.
- Dig the soil to around 30cm depth as this is how far the plant’s taproot can develop. Work some organic compost or manure into the soil to help provide the necessary nutrients for growth.
- Sow spinach seeds directly into the garden.
- Plant seeds 1/2 inch deep and 2 inches apart in wide rows.
- For a continuous harvest, sow every two weeks.
- Spinach resents transplanting.
- Seeds germinate well in temperatures from 50-75 degrees F.
- Thin seedlings to 6 inches apart when the plants are 4 inches tall.
- Be ruthless; crowded plants are more likely to bolt (go to seed prematurely), and you can use the cuts in salads.
- Keep the soil moist, and feed plants manure tea or fish emulsion every 10 days until they’re 6 inches tall.
- Mulch established plants to conserve moisture and deter weeds and cover the area with floating row covers to discourage insects.
- Spinach is ready to harvest at about 40-50 days after planting.
- Cut spinach leaves as you need them from the outside of the plant, or harvest entire plants when they reach maturity and before they begin to flower. (If you see buds starting to form at the centre, cut the whole plant immediately.)
