Then, you will need to place the container in areas with a cool temperature. In 40 days, you will be harvesting a tasty, healthy and fresh nutritious leafy green.

Read on the following ultimate steps to successfully grow spinach indoors.

1. Choose a container

Spinach plants are not big nor high which make them easy to grow in a container. The container should be wide rather than deep. A depth of 8 to 10 inches is more than enough.

Spinach needs space that is why the container should be wide. An appropriate container should provide at least 5 inches of space between the plants (seeds).

Don’t forget that the container should have drainage holes in the bottom.

2. Planting

Spinach requires a nutrient-rich soil. In order to successfully grow spinach indoors in containers, you should use a quality potting mix soil that is rich in organic matter. You can find such a soil at garden centers and nurseries.

Well-draining soil is a significant and a crucial factor for your spinach to grow in containers. You should avoid soil that stays waterlogged and remember that soil PH must be neutral.

Planting the seeds is the easiest part. Just sow the seed following the instructions provided by the package direction and cover them fully with soil. Water the seeds frequently and they will sprout approximately within two weeks.

3. Location

One of the most common questions in growing spinach indoors revolves around the location:

Where should I put my spinach?

Next to a window?

In the kitchen?

As we stated before, Spinach is a cool-season crop that tends to grow better and faster in a moderate climate.

The perfect temperature for spinach to grow varies between 41 to 75 degrees Fahrenheit. Consequently, the best location for your spinach is next to a window that does not radiate high heat during sunlight hours.

However, you should be careful not to expose your spinach to excessive light. If your spinach is exposed to more than 14 hours of light per day, the plant will “bolt”. Therefore, ideally, 6 to 8 hours of direct sun or light are perfect for your indoor spinach to grow.

4. watering

One of the most commonly committed mistakes when growing spinach indoors is water stagnation. Water stagnation leads to the development of rot and other fungal diseases.

You need to water your spinach more frequently but do it carefully. Avoid water stagnation and wetting the foliage. Make sure that the soil remains moist but not soggy.

5. Fertilizing

Nitrogen is another critical factor to successfully grow healthy spinach indoors in a container. When you’re planting, you should mix time-based fertilizers or you can also add a lot of compost or well-rotted manure. This process will slowly provide nutrient to your spinach.

In the middle of the growth, it is necessary that you feed the plant with emulsion, compost or manure. In this way, you will promote the plant organically. Additionally, you could also feed the plant with balanced liquid fertilizer at regular intervals.

6. Mulching

Mulching is another important factor for your spinach to grow indoors.  Mulching plants with organic matter will contribute to retaining moisture.

7. Harvesting

When the leaves become large enough to eat, you should harvest them. It usually starts when the plant has grown at least 6 healthy leaves.

Now, you must be inquiring how would you know the healthy leaves? Well, they are recognizable by sight. They are about 4 inches long.

There are two harvesting options. Either you cut off the external leaves and let the internal new one grow or you use a knife or a scissor to cut the whole plant off. Don’t worry, the plant will grow again.

Harvesting should be done before the plant start flowering. Once it starts flowering, it will develop a bitter taste. This is called bolting. You should also bear in mind that the small, young, and tender leaves are the most delicious and tasty.
