When Do You Harvest Spinach?

When do you harvest spinach now that you have tended to your plants and allowed them to grow into healthy leaves?

Spinach is a cool weather plant that is related to swiss chard. It is best grown during the cool season.  It is rare to find it growing during the heat of the summer.  Spinach is a popular crop to plant in the early spring or late summer since it withstands cold and tolerates full sun to partial shade.

What is so good about spinach plants is that you can harvest them as microgreen baby leaves or mature leaves. All of these are tasty when eaten raw or cooked. Each growth stage for the spinach has its benefit to the gardeners.

To enjoy spinach’s different flavors and textures, you can easily plant spinach in intervals. Use the outer leaves like baby spinach or mature spinach. To learn when to harvest spinach, here is a detailed guide.

When Do You Harvest Spinach?

You can harvest spinach throughout the growing season, from early spring to fall harvest. This cool-season crop is the best grown in the spring and again in the early fall when the soil temperature is between 45 and 60 degrees Fahrenheit.

You can harvest spinach leaves as a baby or mature leaves. Baby leaves from young plants are excellent if you want a more tender texture and sweeter flavor. The mature leaves are naturally chewy with a similar taste to swiss chard. If you leave your spinach to go to seeding, you will not consume the leaves as they will have a bitter taste and a tough texture.

When is spinach ready to harvest?  The best size to harvest baby spinach is when the plant is at least 6 inches tall, and the leaves are at least 2 to 3 inches long. Harvest mature leaves when they are about 3 to 6 inches long. A few leaves might even be larger, but they will be good to eat as long as the plant has not set seed.

Your spinach plants can easily bolt once the outside temperature reaches 25 degrees Fahrenheit. You will notice a stem growing up in the middle of the foliage as the plant prepares to set seeds. This is the time to harvest the entire plant because the formation of spinach seeds takes away the energy required for healthy leaf production. If you do not harvest, the entire older leaves will become bitter.

How To Harvest Spinach

Spinach harvesting is an easy process.  However, there are different methods to harvest depending on the maturity of a plant. You can harvest your spinach by cutting the leaf from the spinach plant. This way, you are harvesting only what you need at the time of use.

This harvesting method will encourage new growth from the entire plant. Spinach is a fast-growing plant that tolerates multiple harvests.

When harvesting the leaves, whether baby or mature, take only the outer larger leaves and no more than 1/4 of the whole plant. Harvesting only a small amount will ensure the spinach continues to grow. Use a sharp kitchen knife or utility scissors and leave at least 1/2 inch of stem on the plant to keep the leaf node intact and encourage thicker growth. If your stems are tender, you can easily pinch your leaves from the plant when harvesting.

Another harvesting method is called clear-cutting by the bunch. This is excellent when you harvest lots of leaves at once to dry or freeze them for later use. To harvest using this method, use a sharp knife and gather up all the spinach leaves of one plant into a bunch.  Cut the stems at least 1/2 inch above the crown. The crown is just above the soil surface where all the stems meet. Within 10 to 14 days, you can get a second harvest following this method.

The last method to harvest the spinach plants is removing the entire root system. This is an excellent method if you’re ready to remove the whole crop at the end of the season or you don’t want the spinach to regrow. Use a sharp knife and cut below the crown so that the whole plant comes up from the soil. The remaining roots will decompose, adding nutrients to your soil.

Storing Fresh Spinach

After harvesting your fresh spinach leaves, you now need to store them in the best way possible.  The two different ways to keep your spinach are dry cold storage and freezer storage.  For these two methods, you will need to remove any slimy, wilted, or off-colored leaves from the batch before you store them. These leaves will be the potential cause of the rest going bad.

Before storing your spinach, clean them by rinsing them with cold water and then use a salad spinner to get rid of the excess water. Place the leaves on a paper towel and pat them dry.

For dry cold storage, wrap your spinach in a plastic bag. Remove any excess air before placing it in the refrigerator. This is the most popular storage method because it is easy and keeps your spinach fresh for at least 10 days.

Storing Fresh Spinach

When storing your spinach in the fridge, the last thing you want is to leave the leaves wet. Wet spinach quickly turns slimy, thus rotting.

When storing your spinach, you could also wait to wash them when you’re ready to use them to eliminate the potential for moisture damage. Alternatively, you can put them in a plastic container to increase the storage life from 12 to 14 days.

You can do a quick rinse to remove all the dirt and insects for freezer storage. You will not need to dry them because they will need to be blanched in boiling water or steam for 2 minutes. After blanching, place them in ice water for another 2 minutes to stop the cooking process. Once they have cooled, use a salad spinner to remove excess water and dry them with a towel. The frozen spinach will last in the freezer for up to one year.
