Everything You Need To Know About Growing Spinach


Spinach is a fast and easy-to-grow leafy green vegetable that can be grown in potting containers if you are short on space.

Spinach is an annual plant that is native to central and Western Asia.

They prefer cool weather and are frost tolerant allowing them to be transplanted into the soil before most other crops.

HOW TO PLANT SPINACH

Spinach is best grown in well-drained soil with full sun and a soil pH range of 6.5 through 8.0.

They can be sown straight into the soil after the last frost or as I prefer they can be started 8 to 10 weeks before the last frost indoors using a cardboard seed starting tray.

They are best planted 8 to 12 inches apart and each row should be about 12 inches apart and about half of an inch deep.

The seeds can be sprouted in cardboard seed starters indoors 3 – 4 weeks before the last frost and the seed will take between 7 – 10 days to germinate.

If you are short on space then they can be grown in potting containers that can be placed anywhere or they can be put on shepherd’s hooks.

FERTILIZING AND WATERING

To avoid any possible issues of over-fertilizing your spinach, you should test your soil before adding any fertilizers.

They are best fertilized when established with a balanced fertilizer such as 10-10-10 but a higher nitrogen content such as a 15-10-10 will provide better foliage growth every two weeks.

if you are growing an organic garden then a homemade liquid fertilizer can be used.

They prefer consistently moist soil but not soaked and because they have shallow root systems, they don’t need to be water deep.

BLOOMS

Spinach produces a cluster of red, pink, or white blooms that appear from a thin stem that shoots up from the soil.

Their buds and blooms are edible and often add to a salad.

The term bolting is a term used when a plant goes to seed for the next season and when spinach bolts the leaves become bitter or tasteless.

HARVESTING

Spinach is ready for harvesting in 37 – 45 days after the seeds have been sown into the soil.

For a consistent harvest, it is suggested to resow about every 7 days and the seed can be started indoors using cardboard seed starters.

PROPAGATING

Spinach is an annual plant, therefore propagating them through seed is the only way and some plants should be allowed to go to seed for the following season.

Seeds need to mature properly, the seed coating needs to dry and cure, and they need a rest period prior to planting. Waiting until the seeds have fully cured is the best method of vegetable seed growing.

When stored in a cool and dry location the seeds will last for three years, therefore when storing them it is important to add the date.

PESTS

Spinach has few pests that feed on them but using natural methods such as attracting predators and using natural insecticides such as essential oils, diatomaceous earth, or insecticidal soap will keep your pest control organic.

  • Cutworms
  • Slugs
  • Snails
  • Flea beetles

DISEASES

Spinich that is planted close together can develop mold and mildew issues during times of high humidity.

If this is the case then preventive measures may need to be taken.

Joel SImon

As a kid, Joel found enjoyment in caring for the many houseplants he grew up with, learning how to transplant them safely, cloning them, and more. At about the age of 10, he wanted to see if he could sprout an orange seed from a store-bought orange and ended up using it as a science experiment in a school project. Throughout the many years of gardening, he has helped many friends and family set up their food and botanical gardens. After years of caring for plants, he was talking with other gardeners and discovering old methods of farming and botanical gardening. Joel has decided to share his knowledge for others to enjoy as he has for many years.
