Where do spinach seeds come from?

Spinach seeds exist in the form of utricles. Generally, one fruit contains one seed. The utricle is oval or nearly round, flat on both sides, and has a brown peel.

How to get spinach seeds

When eating spinach, you can leave the roots and plant them in flower pots or vegetable gardens, let them bloom, and after insect pollination or artificial pollination, the fruits will ripen and you can collect the seeds.

How to save spinach seeds

When spinach starts to bolt, it is necessary to clear out the sick and weak plants, hybrid plants, absolute male plants, and female plants that bolt early, leaving 3 to 5 nutritious male plants that bloom at the same time as the female plants. After seeding, all the nutritious male plants can be pulled out to reduce nutrient consumption. When most of the plant stems and leaves have turned yellow and the fruit skin is yellow-green, the seed plants can be harvested, then threshed, dried and stored.

How to Plant Spinach Seeds

1. Seed growth process

After spinach is sown, the seeds absorb water and swell in the soil, then the embryo in the seed begins to grow, and the radicle breaks through the pericarp and continues to grow. This phenomenon is usually called seed germination. In fact, it is not a bud but a radicle. This process is called seed germination.

After the seeds germinate, cotyledons will grow, and leaf primordia will form at the seedling end of the cotyledons, and then develop into true leaves. Later, the number, area and weight of true leaves will gradually increase. The number, area and weight of true leaves are related to the spinach yield.

2. Seed sowing time

Spinach can be planted all year round, but it is best to plant it in autumn. The spinach planted at this time has the highest yield and the best quality of the whole year.

3. Seed planting method

Spinach fields are generally sown by broadcasting. The seeds need to be soaked in advance, placed in a refrigerator at about 4 degrees for 24 hours, and then germinated at 20-25 degrees. They will germinate in about 3-5 days and can then be sown and covered with a thin layer of soil. If the temperature is low, a film can be covered.
