How to Propagate Spinach

Spinach is a cool-weather leafy green plant that grows best in neutral soil. Spinach is propagated by seed, usually directly in the garden. Because of its shallow roots, spinach doesn't transplant well. If your soil is very wet in the spring, germinate seeds in peat pots that can be planted in the soil after the season's last frost.

Instructions

    • 1

      Prepare a garden bed in a location that receives at least eight hours of daily sun as soon as the soil is thawed enough to work. Plant spinach seed directly in the garden four weeks before the last frost of the season or as soon as you can work the soil. Plant the seeds 1 inch deep in rows 12 to 18 inches apart. Thin the seedlings to 6 inches apart.

      Plant new seeds every week until the last frost so you'll have spinach to harvest all summer.

    • 3

      Water your spinach enough to keep the soil evenly moist. Spinach has shallow roots and is sensitive to being dried out. Mulch the plants once they become seedlings to retain moisture and retard weed growth.

      Add lime to your spinach garden to bring the soil pH to 6.0, if the plant shows signs that the soil is too acidic. Signs include poor germination and yellowed leaf tips. Don't fertilize unless the spinach leaves are light green.
