Nowadays, many people like to grow their own vegetables at home, not only to meet their daily needs but also to eat their own vegetables with great pleasure.

If you want to grow your own vegetables, spinach is a good option, spinach is rich in nutrients, high food value, and relatively easy to grow and manage.

So how do you indoor spinach growing?



Seeds that are 1 to 2 years old have better germination power and can generally be kept for 3 to 5 years.

Select the seeds, it has a very large number of varieties, each with its own advantages.

If you plant in summer, then choose a variety that is resistant to heat and drought, if you plant in winter, because of low temperatures, then choose one that is resistant to low temperatures, if you plant in autumn, because the plant is prone to disease, then choose one that is resistant to disease, if you plant in spring, because it rains a lot, then choose one that is resistant to flooding.

In addition to the season of planting, the choice of variety depends on your local weather.

When we choose the seeds, we need to germinate them, but if we plant them in spring, then we don’t need to germinate them, and they will come out soon after we sow them directly in this season.

If it is planted in other seasons, then germination is needed so that the seeds can germinate quickly.


The method of germination is very simple, that is, first put the seeds in water to soak for about 24 hours, or you can directly put the seeds in the refrigerator for a day.

To germinate seeds in summer and autumn, soak the seeds in water for 12 hours 1 week before sowing, put them in a refrigerator or freezer for 24 hours at about 4°C (39.2°F), then germinate them at 20°C-25°C (68°F-77°F), and sow them after 3-5 days of germination. Dry or wet seeds can be sown in winter and spring.

When it is almost time, the seeds are wrapped in a wet cloth, which can be a gauze cloth of choice. The cloth is then placed at room temperature to germinate, and small shoots will appear in about four days.

One thing to note here is that the cloth must be kept moist at all times, not completely dry, as there is no way to germinate if it is dry.



Although spinach is very easy to grow, but the preliminary preparation work is not sloppy at all.

The container for planting spinach can not be too deep, because spinach is a fast-growing vegetable, rooting will not be very deep, but it is recommended that the area is slightly larger, like flower pots, wooden pots, plastic pots as long as the bottom poke a few holes, can be used to plant spinach.

No matter what species you choose, be aware that there must be small holes at the bottom. This will allow the excess water inside the soil to drain.

If there are no holes, too much water will rot the roots of the spinach. The soil you choose must be the kind of soil that is soft and well-drained, you can choose the soil from the garden, which is more likely to produce seedlings.

We first put the soil into a container partly, to leave some soil outside the container.


The soil, we have to choose loose and breathable and soft soil so that spinach can easily arch away from the soil and take root when it is still small.

Spinach is highly adaptable to soil, but it is still good to have a fertile soil with strong water and fertility retention, with a suitable pH of 7.3 – 8.2.

The soil must not be dry, a moist environment is conducive to seedling emergence. The specific method of sowing is to sow the seeds on the soil surface and then put on the soil previously left out.

Do not cover the soil too thick, too thick will affect the speed of germination.


The first thing that you need to do is to use water to make sure that the soil is watered down and that you can plant the spinach in your yard or windowsill.

First of all, water the soil with water, watering it wet, so that the soil is not dry, and do not have excess water on the soil.

Once you have prepared the potting soil, put it in a ventilated and cool place and you are ready to sow the seeds.

The seeds of spinach are very small, so we must be careful when sowing the seeds, not too dense, otherwise it will affect the subsequent growth of spinach.

The actual seeds will be the most important part of the plant.

It is also necessary to take a spray bottle every day to spray a long distance towards the soil, the seeds will germinate only in a moist environment.


The most suitable temperature for it to develop quickly and normally is between 15 degrees and 25 degrees, at this temperature the development is faster than usual and the development is less prone to pests and diseases at this temperature.

Although spinach can be grown throughout the year, not all temperatures are suitable for its development.

If the temperature is below 5 degrees, the plant is prone to frostbite and non-development.

Above 30 degrees, the plant will be burned. This will affect the yield and quality of spinach.


After sowing the seeds, we need to place the container in a ventilated and sunny place.

When most of the spinach has sprouted, we can move the container to a sunny place so that the spinach can photosynthesize better and grow faster.

It is important to note that the sunlight is not all at once, you need to gradually sunlight, and even if you have grown spinach, you can not see the noon sunlight in the summer, otherwise, it will be sun-damaged.

The actual fact is that you will need a lot of water during the growing period, especially in this kind of well-ventilated summer season, spinach needs more water, so you can water the spinach once every evening to be able to ensure the normal growth of spinach.

It takes about a month from the time of sowing to the time the spinach is eaten in your mouth, so you must remember to observe the growth status of the spinach in time.


Generally, around forty days to grow 4~5 leaves can be harvested, every 20 days can be harvested once, a total of 2-3 times. The actual fact is that you’ll be able to get a lot more than just a couple of days to get a lot more.


Spinach is very adaptable and vigorous and can develop very quickly as soon as the seedlings emerge.

In order to ensure its future production, it is time to interplant when the seedlings have 3-4 leaves.

The interplanting is to remove the weaker plants, and when you remove the plants, you should be careful not to damage the remaining healthy plants.

You should also weed the seedlings to prevent the weeds from consuming nutrients, and apply fertilizer once after the interplanting, being careful not to make it too dense.

During its development, if the water and fertilizer are not enough and the nutrients are not absorbed enough, then it will not develop well, and under the same temperature and light, it will have the situation of shoots.

If the nitrogen fertilizer applied during the development process is not enough, it will also appear to be the case. The seeds of the spinach are not pure, but they are also pure.

You should remember to shade your spinach in hot weather, if it is too hot, it will also lead to the seedling.

It is also prone to pests and diseases during its developmental stage, so we need to treat the plant according to the pests that appear on it.


  1. After the spinach sprouted tiny leaves, the soil dried up and started watering, as long as it was not waterlogged.
  2. During the growth of spinach, pay attention to fertilization, when the leaves grow to four or five, you can use rotten chicken manure, cow manure, sheep manure, even rabbit manure, or with the nutrient solution can be.
  3. If the winter temperature is low, you can also get a small plastic shed, which will grow faster.
  4. Watering is not easy to be too diligent, just keep the soil moist. If the density of seedlings is too large, in 3 to 4 true leaves time seedlings once, you can pull out the big seedlings eat, small seedlings continue to grow. Like light but not tolerate sunlight, need to pay attention to shade.
