How to Grow Spinach Indoors

Container gardening is ideal for indoor spinach growing. You can use containers made of any material, from plastic to clay to metal. Just be sure to choose a container that provides enough space for the spinach to grow and has ample draining for healthier roots. Since spinach roots need room to spread out, you may need to transplant the spinach if it should outgrow its original container.

What does spinach need good drainage?

No matter which container you choose, it is important to ensure there is ample drainage for excess water to escape. Root systems that sit in over wet soil continuously can lead to fungus and root rot.

Hydroponics for Growing Spinach

Hydroponics, or growing plants in water, is another option for indoor spinach growing. This method requires a bit more setup but is more efficient and can produce higher yields. To grow spinach hydroponically, you’ll need a hydroponic system and nutrient-rich water. Look for hydroponic kits online or at your local gardening store.

Spinach needs plenty of light to grow. You can use natural light or artificial light sources like grow lights. If you’re using natural light, place your spinach near a sunny window. Spinach needs at least six hours of direct sunlight per day. If you’re using grow lights, choose ones that emit full-spectrum light for optimal growth. Position the lights about six inches from the plants and keep them on for 14-16 hours per day.


When it comes to watering spinach, it’s important to strike a balance between over-watering and under-watering. Spinach needs moist soil, but not soil that’s soaked through. Water your spinach when the soil feels dry to the touch. Use a watering can or spray bottle to gently water the soil, taking care not to splash water on the leaves. To avoid leaf rot, consider using a watering probe to check the moisture of the soil.

Spinach grows quickly! In just 40 days, you’ll be able to harvest your first crop of indoor-grown spinach. Simply snip off the outermost leaves when they reach a few inches in length. Leave the inner leaves to continue growing.


To store spinach, wrap it in a clean, damp cloth and place it in the refrigerator. It will stay fresh for up to 5 days.

You can also freeze spinach in freezer bags to enjoy later. Frozen spinach can be used in smoothies, soups, stews, and more.

Growing spinach indoors is a simple, rewarding project for any homesteader. With the right containers, lighting, and watering techniques, you can grow delicious, nutritious spinach all year round.
