How to plant spinach

Spinacia oleracea

Spinach, sometimes called real spinach, European spinach or Persian spinach to distinguish it from New Zealand spinach, is a vegetable originally from Persia, now Iran. Its leaves are eaten raw or cooked , being quite nutritious. However, its consumption cannot be exaggerated, as its leaves also contain a high concentration of oxalates.

Climate

Spinach grows best in regions with mild temperatures, with an ideal temperature range of 13 ° C to 20 ° C. However, it can be grown in regions where the average temperature during the plant’s life cycle is between 2 ° C and 27 ° C. Elevated temperatures can induce early flowering.

Brightness

Spinach can be grown in direct sunlight or in partial shade.

In hot climates, choose the growing place so that the plant is not exposed to direct sunlight during the hottest hours of the day.

Ground

The soil must be well drained, fertile, rich in organic matter and with good nitrogen availability. The ideal soil pH for growing spinach is between 6 and 7.5.

Irrigation

Irrigate frequently so that the soil is kept moist, but not soaked.

Planting

Sow directly at the final location of the vegetable garden or sow in seedlings, small pots or other containers and transplant when the seedlings have four true leaves. The seeds can be up to 1 cm deep in the soil and usually take a week or two to germinate under suitable conditions.

The recommended spacing varies with the chosen cultivar, but it is generally possible to use a spacing of 30 to 45 cm between the cultivation lines and 5 to 15 cm between plants. A small spacing between plants increases productivity per area, but a larger spacing makes it possible to harvest larger plants. Spinach can also be grown in pots and bibs.

Cultivation

Remove invasive plants that are competing for resources and nutrients.

Harvest

Spinach leaves can be harvested individually from 40 to 120 days after planting.

To perform the individual harvest of the leaves, the plant must have at least 6 leaves. Pick the outermost leaves that are well developed.

Spinach can also be plucked whole or can be cut approximately 2.5 cm above the ground, in which case the plant can sprout and produce a new crop.

When grown in a warm climate, harvest the entire plant before inflorescence appears.
