Varieties and classification of spinach

How to plant them?
Sowing spinach seeds should be done directly in the soil 2cm deep. If you are going to do it in orchards or terraces, I advise you to sow them in rows with a distance of 30cm; and, if you are going to do it in planters, you will have to spread the seeds around the surface.
When the plants arise, rinse them at a distance of 10cm between each of them and, in the planters, leave a radius of 20cm between each spinach plant.
Care and collection
Spinach can grow properly without too much sun , so I advise you to place them in a place that has a lot of shade during the day. Also, they will have to be watered every time the earth is about to dry out to maintain moisture, but you should avoid waterlogging because that can rot the roots.
When collecting spinach , it is not necessary to tear the entire plant, but rather to take out its outer leaves.
