How to Grow Spinach in Pots?

Growing spinach from seeds is the most straightforward process:

Sow seeds 1/2 inch deep, directly in containers or a seed tray. Seedlings will germinate in 5 to 14 days, depending on the variety and growing conditions.

If you have sown seeds in a seed tray, wait until 2-3 true leaves appear on each plant and then carefully transplant them into the pots. However, it’s better to plant spinach directly in the desired pots. Also, it’s one of the fast-growing vegetables, and you’ll be ready to harvest it within one month after germination.

Best Container Size for Growing Spinach in Pots

A 6 to 8 inches deep container and as wide as you want would be best for growing spinach in pots. You don’t need a very deep pot for it but a wider one. You can also go for wooden boxes, window boxes, railing planters, or crates, depending on your space on a patio or a balcony.


Growing Spinach Indoors

Growing spinach indoors on a windowsill is a great idea, as it doesn’t require full sunlight. You can also place its pot on a kitchen window, balcony, or practically any place where it gets at least 4 hours of direct sun.


Spacing Spinach

Provide each spinach plant a space of 3 inches. If you want to pick large leaves, give a little more space to each plant. Avoid spacing it too much or growing the plant too crowded as it will result in overly small or large leaves, which will hamper the taste.


Requirements for Growing Spinach in Containers

Position

If you are growing spinach in fall (autumn), keep the plant in a sunny spot (in mild climates) for shorter days and less sun intensity.

For spring and summer planting, keep your potted plants in a location that receives some shade, especially in the afternoon.

In a subtropical or tropical climate, place the containers in a spot that receives a bit of shade. The plant will do just fine in partial shade too.

Soil

For growing spinach in containers, use a quality potting mix rich in organic matter. The texture of the soil must be crumbly and loamy.

Avoid a growing medium that clogs the drainage and remains waterlogged. Well-draining soil with a neutral pH is the most crucial factor for the optimum growth of spinach in containers.

Watering

When growing spinach in containers, avoid water stagnation because it will lead to the development of rot and various fungal diseases. Also, avoid wetting the foliage. Keep the soil moist but not soggy or wet. Make sure the pot has a drainage hole at the bottom.

Temperature

Spinach seeds can germinate both in temperatures as low as 40 F (4 C) and in high temperatures. However, the best soil temperature for growing spinach is 50-80 F (10-27 C).

Many spinach cultivars can tolerate temperatures down to 20 F (-6) and up to 90 F (32 C) easily. Once the temperature starts to soar high, you may need to provide shade to your plants.

Spinach Care

Growing spinach in pots doesn’t need special care. Regular watering, fertilizing, and the right soil are critical to a great harvest.

Fertilizing

For growing healthy green spinach, you have to provide nitrogen. When planting, mix time-based fertilizer, or add 30 percent of compost or well-rotted manure in the soil. This will provide nutrients slowly.

Feeding the plant with fish emulsion, compost, or manure tea in the middle of the growth is a nice organic way to promote the plants.

If you have not added time-based fertilizer, feed the plant with balanced liquid fertilizer once in 2-4 weeks in half strength.

Mulching

Do mulching, even if you’re growing spinach in pots. Mulching plants with organic matter will help in retaining moisture.

Pests and Diseases

You don’t need to worry much about pests while growing spinach in containers. However, keeping an eye on leaf-eating insects like slugs, caterpillars, and other common garden pests like aphids will help you eliminate them on time.


Super Tips for Growing Spinach in Warm Climates

It is a cool-season crop, but growing spinach in arid, tropical, and subtropical climates is extremely easy. Moreover, you can grow it successively as a bi-annual crop, except in hot summer months. You’ll need to provide shade and enough water to keep the soil temperature cool and moist.

In warm weather, vegetables like lettuce and spinach begin to bolt early and set seeds. One of the most important things you need to consider when growing spinach in the hot climates is to grow heat-tolerant varieties like Corrente, Canadian Green, Akarenso, Alkame, Samba, and Alrite. These varieties easily tolerate the heat and humidity.


Harvesting Spinach

The spinach plant will be ready for harvest 25 to 50 days after germination, depending on the growing conditions and cultivar.

Harvest when the plant has formed at least 5-6 healthy leaves, 3-4 inches in length. Pick outer leaves first and leave the new inner leaves so that they continue to grow, or cut the whole plant at the base with a knife or scissor, and the plant will resprout again.

Note: When the weather becomes humid and hot (in warm climates), the plant tends to form an erect stem, on which you can see some small yellow or green flowers developing. To coincide with the flowering and the subsequent production of flowers, the plant’s foliage thickens and changes in flavor (more bitter), which is called bolting, so it is convenient to harvest the plant before it starts flowering for better taste.

    Thanks again

  6. Thank you so much for sharing in an understanding manner,I live in MT so I have began planning for the next planting season.I can’t start soon enough,thank you.

  7. I have planted few seeds in a wide pot and it did germinate well. But, all of a sudden it started to fall off. Would there be a reason or care I’m missing?

    • How deep was the pot that the plant was in? & how many “few seeds” did you plant in that pot? Also, was there any bugs in the area that could’ve gotten into the plant?

  8. May I know how many seedlings do you plant in the 6″ deep pot? How many seeds per hole do you recommend if I plant using the seed tray?
    Thanks.

  9. Thanks for the tips for warmer climate varieties of Spinach. I will have to look at some Asian varieties since we are in NC. Where are all you planting?

  10. My spinach plants are growing to about 3-4 inches long and then just falling to the sides. It looks like the plants are falling because unable to hold their own weight. I’ve tried sowing them deeper too with pretty much same results. What can I do differently?

  11. I can’t wait to starts my veggies garden,this year I got some heirloom tomatoes seed and I got big containers for them.Thank for the hints, I had learned a lot.

  12. This is so thoroughly yet concisely written and easy to understand that it actually makes me believe that even I would be able to follow these directions. Thank you so much for posting.

  13. Alternatively, you can keep your pot outdoors after seeding, as long as the ground has thawed. Even though you aren’t planting the spinach in the ground, this is a good indicator that your spinach could survive outside. Spinach can survive temperatures as low as 15 °F (?9 °C).
