How to Grow Spinach in Pots

Spinach, whether it’s fresh or frozen, is one of the most versatile and nutritious leafy greens out there. It can be used in side dishes, salads, sandwiches, soups, smoothies, and so much more! But, if you’re like most people, you might not have the room in your garden to grow enough spinach to fill your plate every night of the week — and even if you did, keeping it growing can be hard work with all the backbreaking weeding that’s involved. One solution to this problem is to grow your spinach in pots!

Gather Your Materials

Before you can start growing spinach, you’ll need to gather a few materials. 

You’ll need:

  • Some pots or containers
  • Quality potting soil
  • Organic fertilizer
  • Some spinach seeds
  • Drill 
  • Watering can or hose
  • Peat moss (optional)
  • Compost (optional)

Once you have all of your materials, you’re ready to get started.

Step 1: Choose a Location

The first step to growing spinach in pots is to choose a location. You’ll want to find a spot that gets plenty of sunlight, as spinach is a sun-loving plant. But you also don’t want to put your pot in an area that gets too hot, as this can cause the leaves to wilt. A location with morning sun and afternoon shade is ideal. Consider an area with partial sun in the hotter summer months. 

Step 2: How To Choose Your Pots

There are a number of different factors to consider when choosing the right pots for your spinach.

  • Size of the pot: You’ll want to ensure that the size of your pot is big enough to allow for root growth, but at the same time, not so big that it’s too heavy to lift.
  • Depth and height of your container: Make sure that your container has a depth of at least 6 inches (15 cm) and that it’s tall enough to allow for adequate water drainage.
  • Drainage holes: Ensure that there are holes in the bottom of your container, as this will prevent water from draining properly and can lead to root rot.

Step 3: Prepare the Soil

You will now need to gather your containers and prepare the soil to get ready for spinach speed planting. Your plants will grow better if you mix in some organic matter, such as peat moss into the soil at this point (but if you don’t have any available, it’s okay to skip this step).

Add enough soil so that when it’s placed in your pots, there is an inch or two of space between the top of the pot and the soil line. Compost is another welcome addition to the soil. Consider adding 2-4 inches of compost on top of the soil for best results. 

Make sure your pot has holes drilled into it for drainage about 1 inch from the bottom on all sides.

Step 4: Plant the Seeds

After ensuring your containers are filled with soil (and compost/peat moss) up to 3-inches deep (assuming you’re using all of the same types of containers.) Make a hole twice as wide as the width of your seed using your fingers or an object, such as a spoon. Place the seeds in the hole at a depth that’s 1/2 inch below the surface of the soil. If you’re planting multiple seeds, space them 2 to 3 inches apart from each other. 

Sprinkle water over the seeds so they have some moisture, then cover them back up with soil by patting it down gently so that there are no air pockets. Planting your spinach plants this way will help ensure they grow evenly without any gaps between them when they sprout their first leaves and form their crowns (the thickest part).

Step 5: Water the Plants

Once the plants are in the pot, it is important to water them regularly. The soil should be moist, but not soggy. Water the plants about once a week or when the soil feels dry. Avoid getting water on the leaves, as this can encourage fungal growth.

If you live in a hot climate, you may need to water more often. Be sure to check the plants regularly and adjust your watering schedule as needed. Always ensure that the holes under the bottom of your pots are providing adequate drainage.

Step 6: Apply Fertilizer

Fertilizer helps spinach plants grow strong and healthy. Apply a balanced fertilizer, such as 10-10-10, to the soil around the base of the plant. Be sure to follow the manufacturer’s directions on how much fertilizer to use. Apply fertilizer every two weeks during the growing season.

Step 7: Harvest Time!

When your spinach leaves are about 6 inches long, it’s time to harvest! Most spinach plants take up to six weeks to mature. You can cut the entire plant to just above the soil line, or you can snip off individual leaves as needed. Be sure to use sharp scissors or a knife so you don’t damage the plant.

Once you’ve harvested your spinach, wash it thoroughly and enjoy! If you plan on eating all of the spinach right away, store it in plastic wrap or an airtight container in the fridge – it can last up to for 10 days.

If you have leftovers, blanch them before storing by plunging them into boiling water for 30 seconds and then soaking them in ice water to stop the cooking process. Store blanched spinach loosely wrapped with plastic wrap lasts in the fridge for about three days.

Why Grow Spinach?

Popeye was onto something when he ate spinach to gain strength. This leafy green is packed with nutrients like vitamins A, C, K, folate, calcium, iron, magnesium, potassium, and more. It’s also a good source of fiber and protein. All of these nutrients work together to keep your bones strong and your immune system functioning properly.
