How to Grow Indoor Spinach

You’re more than ready to begin growing your indoor spinach garden. How do you do it? Here are some steps to follow.

Pick Your Pot

First thing’s first, and that’s getting a vessel for your spinach. Some people will use seed trays for this and others a pot. If you go the pot route, then its depth matters more than its width. If you pot isn’t at least six inches deep, keep shopping around. It’s best if you can find a pot with a depth of eight inches, but it’s not necessary.

Sow the Seeds

Those who choose a seed tray can put the seed container right in the tray if they so desire. Bury the seeds at a depth of half an inch. Within five days, sometimes up to two weeks, your spinach should begin growing.

If planting spinach in a pot, you must give it adequate room. How much space the seeds need will depend on the leaf size of the vegetable when it’s fully grown. If the spinach will have large leaves, then keep the seeds five inches from each other. If you anticipate smaller leaves, then three inches of space should work fine. Some gardeners even plant their spinach seeds two inches from each other, but that’s only when they plan for an early harvest.

We have to talk about the soil you use for planting as well. You can get away with most store-bought potting mixes, but make sure yours has lots of organic matter. Loamy and crumbly soil supports spinach best. Check the pH of the soil as well and make sure it’s as close to neutral as possible. Your soil should also drain well, as if it gets backed up, it could impact spinach growth.

Place Your Pot

With your soil in the pot and the seeds ready as well, you need to put your pot in an optimal place. If you’re growing your spinach in the spring or summertime, then it’s important you avoid spots that are too sunny. Spinach needs some shade to thrive. When planting this veggie in the fall then, go for sunnier areas because the sun sets early.

Maintain the Temperature

Spinach is rather hardy, but you still want to check your thermostat to ensure you don’t accidentally kill it. Germination of the seeds can begin at 40 degrees up to 80 degrees Fahrenheit. Just because spinach can withstand temps in the 40s doesn’t mean you have to keep your apartment or home that cold. The seeds do especially well if you set the thermostat to at least 50 degrees.

Some spinach can survive temperature extremes even lower (like 20 degrees) or higher (90 degrees). Should you find yourself in a scenario where the temperatures exceed 90 degrees or more, then you’ll have to safeguard your spinach so it gets some shade.

Water the Plant

Your spinach won’t progress much without you watering it. You can’t just dump water on the plant and call it good, though. Instead, you must take some precautions. As you water your soil, do so until it’s moist, but never let it get fully wet. Keep the water off the spinach foliage, too.

Most importantly, make sure the soil is draining as it should. If too much water sits in the pot, the spinach could develop a fungal disease or root rot.

Mulch and Fertilize

The most maintenance you’ll have to do for your spinach is mulch and fertilize it. When you mulch this vegetable, add more organic matter. This maintains the soil’s moisture content, thus keeping your spinach healthy.

Nitrogen-based fertilizer will augment the growth of your spinach. Manure works as well, but you must make sure it’s rotted. Other options you have for fertilizer include manure tea, compost, or fish emulsion. Apply these when your spinach has sprouted but before it finishes growing.


Growing spinach might be easy, but it’s not fast. It can take over a month before you can harvest the vegetable, sometimes up to 50 days. To decide if your spinach is ready, measure the leaves. Have they grown to three inches, even four? How many leaves does the plant have? Five or six? Then you can begin harvesting.

What Other Veggies Can You Grow Inside?

As we said before, you might soon find yourself clambering to grow more of your own vegetables after your successful experience with the spinach. What other veggies could you plant indoors? Try any of these!

  • Ginger
  • Tomatoes
  • Scallions
  • Kale
  • Arugula
  • Carrots

  • Nectarines
  • Lemons

Ground pepper and salt can add a touch of extra flavor to this nutritious meal.

Another spinach salad you might make calls for apples instead of strawberries. Fuji apples will add some tartness to the dish. You can also include sliced onions again if you want, or skip these. Otherwise, toss in sliced almonds and crumbled feta cheese. Make a homemade dressing from ground black pepper, salt, Dijon mustard, minced garlic, red wine vinegar, and olive oil.

Lots of people love sautéing spinach. You’ll need a sizable skillet and some olive oil to do this. Minced garlic and cut onion add flavor and aroma, as the onion will carmelize during sautéing. A dash of soy sauce also augments flavor. It’s such a tasty dish!
