How to grow spinach?

The Arabs were the ones who introduced the spinach for the first time in Spain in the eleventh century and from there spread to other countries in Europe and America.

Classification of varieties and spinach

The two varieties of spinach that are usually grown are curly leaf and smooth leaf. The first usually sold fresh and is adapted to grow in winter, while the second is sold frozen or canned and usually more consumed than the last.

Spinach can also be classified according to the time of year when sown: spinach King of Denmark and Cleanleaf are sown in spring and summer, while the Broad-leaved Prickly, Monnopa, and Greenmarket spinach are planted in fall-winter.

On the other hand, they may be other varieties that are divided by the color and texture of its leaves. The Lagos spinach has a glossy dark green; the Taunus has thick, shiny green leaves; Martine, has dark green, round leaves, and the variety Viroflay, has smooth green leaves.

How do you plant them?

Planting seeds of spinach should be done directly on the ground to 2cm deep. If you’re going to do in gardens or terraces, I advise planting in rows with a distance of 30cm; and if you’re going to do it in pots, you should spread the seeds around the surface.

When the plants come up, you acláralas at a distance of 10cm between each of them and, in flowerpots, leaving a radius of 20cm between each plant spinach.

Care and collection

Spinach can grow well without much sun, so I advise you to place them on a site that has plenty of shade during the day. Also, we should water them whenever the soil is dry to keep for moisture, but you should avoid water logging because it can rot the roots.

When harvesting spinach is not necessary to pull the entire plant, but rather draw their outer leaves.
