Spinach takes 5 to 10 days to germinate and requires 6 weeks of cool weather from seeding to harvest.
Growing spinach in grow bags is a convenient and space-saving way to cultivate this leafy green. Here's a step-by-step guide to help you grow spinach in grow bags:
1. Choose the Right Grow Bag:
Select a grow bag that is at least 12 inches deep to provide enough space for the spinach roots to develop.
Ensure the bag has good drainage holes to prevent waterlogging.
2. Select the Right Soil:
Use a well-draining, nutrient-rich potting mix. You can mix garden soil with compost or use a pre-made potting mix.
Spinach prefers slightly acidic to neutral soil with a pH between 6.0 and 7.0.
3. Planting Seeds:
Sow spinach seeds directly into the grow bag. Plant the seeds about ½ inch deep and 2 inches apart.
Water the soil lightly after planting to ensure good seed-to-soil contact.
4. Watering:
Keep the soil consistently moist, but not waterlogged. Spinach prefers evenly moist soil.
Water when the top inch of soil feels dry to the touch.
5. Sunlight:
Spinach thrives in partial shade to full sun. Provide at least 4-6 hours of sunlight per day.
If you're growing spinach indoors, place the grow bag near a south-facing window or use artificial grow lights.
6. Fertilizing:
Fertilize the spinach plants every 2-3 weeks with a balanced, water-soluble fertilizer.
Follow the package instructions for the appropriate dosage.
7. Thinning:
Once the spinach seedlings are a few inches tall, thin them to allow proper spacing. Space the plants about 4-6 inches apart.
8. Harvesting:
Harvest spinach leaves when they reach the desired size, typically around 4-6 weeks after planting.
Use clean, sharp scissors to cut the outer leaves, allowing the inner leaves to continue growing.
9. Pests and Diseases:
Keep an eye out for pests like aphids and caterpillars. Control them using organic methods or insecticidal soap.
Prevent diseases by avoiding overhead watering and providing good air circulation.
10. Successive Planting:
To enjoy a continuous harvest, consider planting new batches of spinach every 2-3 weeks.
11. Support and Mulching:
Consider using stakes or other supports if the plants become top-heavy.
Mulch around the base of the plants to help retain moisture and suppress weeds.
Companion Plants:
Companion planting involves strategically planting different crops near each other to enhance growth, deter pests, and improve overall plant health. Here are some companion plants that can be beneficial when grown near spinach:
Lettuce:
Lettuce and spinach have similar growing requirements and make good companions. They can be grown together, sharing space and resources effectively.
Radishes:
Radishes are known to deter leaf-eating insects, such as flea beetles, which can affect spinach. Planting radishes alongside spinach can help protect the spinach plants.
Strawberries:
Strawberries are considered good companions for spinach. They provide ground cover, helping to shade the soil and retain moisture. Spinach, in turn, benefits from the shade and protection.
Onions and Garlic:
Onions and garlic can help deter pests that commonly affect spinach, such as aphids. The strong smell of these alliums can act as a natural repellent.
Carrots:
Carrots and spinach are compatible in terms of growth requirements. Interplanting them can maximize space and create a visually appealing garden.
Beans:
Beans, like peas and other legumes, can enrich the soil with nitrogen through a process called nitrogen fixation. Spinach, being a leafy green, can benefit from the increased nitrogen levels.
Cabbage Family (Broccoli, Cabbage, Kale):
While spinach is not part of the cabbage family, it can be planted near members of this family without competing for the same nutrients. The diverse mix may help deter pests that target specific plant families.
Marigolds:
Marigolds are known for their ability to repel nematodes and other soil-borne pests. Planting marigolds near spinach can help protect the plants from these potential threats.
Chervil:
Chervil is believed to enhance the flavor of spinach when planted nearby. Additionally, chervil is a low-growing herb that won't shade or compete with spinach.
Nasturtiums:
Nasturtiums can attract aphids away from spinach, acting as sacrificial plants. These vibrant flowers are also edible and can add a peppery taste to salads.
Spinach does not grow well next to fennel and potatoes.
How do I fertilize my Spinach?
Before you plant your Spinach you will need to amend the soil by working in a combination of compost and a balanced fertilizer. Amend the soil just a few days before planting so that the fertilizer has a chance to break down some.
What bugs attack Spinach and what gets rid of them?
-
The soft-bodied adults put their needle-like mouths into plant tissue and suck the plant’s juices. While they are taking nutrients from the plant, these pests also insert toxins that affect the plant’s growth.
Aphids can be controlled with an insecticidal soap. Always spray plants in the early evening to reduce the chance of damage. Pay special attention to the lower leaf because that is where they usually are located.
-
Armyworms are the 1 ½-inch long larvae of a tan to brown moth common in gardens. These smooth-skinned larvae vary widely in color, from pale green to dark green-brown and black. Many bear long, orange, white or black stripes along their sides and have a yellow to orange head. They change colors as they mature, making identification tricky.
Check the garden at night with a flashlight for signs of armyworms. If you see any feeding, immediately pluck them from the plants and drop them in a bucket of soapy water. Hand-picking can be an effective control, provided you check for caterpillars each night until you no longer find any larvae after a thorough search.

To get grasshoppers away from your plants.
Clear out any debris in your garden that grasshoppers can use for cover or laying eggs.
Use your companion plants to your advantage! The garlic odor can help deter them. You can use a homemade garlic spray or plant garlic around where you have a problem.
Beneficial critters can be very helpful with this pest as well! Praying mantis (purchase here) can be helpful to fight off grasshoppers. Birds can come to the rescue as well.
-
Nighttime hunts are the best way to go about finding these creatures! Hand-picking and placing the slugs or snails in a salty or soapy solution will ensure that they are killed.
You can set beer out in shallow saucers to attract then drown your slugs.
Diatomaceous earth can also be laid down around your garden to help get rid of them.
What soil pH is best for Spinach?
Spinach will do best in soil with pH between 6.5 and 8.
How do you store Spinach?
Wrap the spinach in dry paper towels or clean dish towels, place it in a sealed freezer bag or plastic container, and put it in the crisper drawer. Freeze the spinach to keep for several months. With this method of preserving you can keep the spinach for nine to 14 months. First, blanch the greens in boiling water for a minute or two, then cool in an ice-water bath for the same amount of time. Drain the bath and squeeze the water out of the spinach by twisting it in your hands. Take about a handful and form the wet spinach into a ball and wrap tightly with plastic wrap, storing them in a large freezer bag. Freeze the spinach balls, and defrost for a ready-to-use serving of greens.
Interesting facts:
During medieval times, the green pigment extracted from spinach was used as ink for artwork.
March 26th is National Spinach Day.
The name “spinach” is derived from the word ispanai meaning green hand.
Even though it is packed full of nutrients, spinach has high levels of oxalate which basically prevents your body from absorbing iron. In order to avoid the negative effect of oxalates, boiling raw spinach will get rid of most of the oxalic acid.
Half a cup of spinach accounts for 1 of the 5 servings of fruits and vegetables that you should eat per day.
Even though they look nothing alike, spinach is a relative of beets.
