How to Grow Spinach Inside

If you're looking for a vegetable packed with most of the nutrients and vitamins vital to a healthy diet, you can't go wrong with spinach (Spinacia oleracea). Try it in salads, stir fries and as a steamed accompaniment to a wide range of fish and meat dishes. If you have harsh winters, or simply don't have the space to grow spinach outdoors, it's not difficult to grow it inside.

Instructions

    • 1

      Select a variety of spinach that is resistant to disease, such as Indian Summer or Melody (crinkle-leaf varieties) and Hector or Olympia (smooth-leaf varieties).

    • 2

      Mix one-part potting soil, one-part vermiculite, one-part peat and one-part perlite in a container at least 10 inches deep.

    • 3

      Press your spinach seeds half an inch below the surface of the soil.

    • 4

      Place your container in a cool, bright room where it will receive at least six hours of bright light per day. Maintain the room temperature at 65 to 70 degrees Fahrenheit.

    • 5

      Position a few grow lights around the container if you are worried that your seeds won't get enough light.

    • 6

      Wait seven to 14 days for seeds to germinate.

    • 7

      Thin your spinach to one seedling every 3 inches.

    • 8

      Water your spinach regularly to keep it consistently moist throughout the growing season.

    • 9

      Fertilize your plants with a balanced organic plant feed every two weeks, starting after the seeds have germinated and you have thinned them.

    • 10

      Harvest your spinach as soon as the leaves are large enough to remove. Cut the leaves from the plant with gardening scissors or pull the whole plant out of the soil with your hand.

    • 11

      Wash your spinach leaves in cold water straight after you pick them.
