How to grow Spinach in USA
Spinach varieties in the USA
In the United States, three primary types of Spinach are grown commercially. These include:
- Savoy – This type of Spinach has crisp, crinkled leaves that are a deep green. It is best suited for use in salads or as a cooked vegetable.
- Semi-Savoy – This type of Spinach has slightly fewer crinkled leaves than Savoy Spinach but still has a deep green color. It is best suited for cooked dishes or as a fresh baby Spinach leaf in salads.
- Smooth-Leaf – This type of Spinach has smooth, dark green leaves and is the most popular type grown commercially in the United States. It is versatile and can be used fresh in salads, cooked as a vegetable, or frozen for later use.
Spinach propagation methods
Spinach is a cool-weather crop that is best sown in early spring or late summer. Spinach can be propagated by seed or by vegetative methods.
- To propagate Spinach by seed, sow the seeds in moistened soil about ½ inch deep and 2 inches apart. Keep the soil moist until seed germination occurs, which usually takes 7-10 days. Once the Spinach seedlings have emerged, thin them to 4 to 6 inches apart.
- To grow Spinach from seed, start by purchasing quality seeds from a reputable source. Once you have your seeds, fill a seed tray or pot with moistened potting mix or vermiculite. Sow the seeds thinly in the tray or pot, and cover them with a thin layer of vermiculite or potting mix. Water the seeds gently.
- Place the tray or pot in a warm location from direct sunlight. The seeds should germinate within 10-14 days. Once they have germinated, thin out the seedlings so that the strongest ones remain.
- Transplant the seedlings into individual containers or your garden bed. If you transplant them into your garden bed, space them about 15cm apart. Water them well after transplanting.
- Spinach plants need full sun, partial shade, and well-drained soil high in organic matter. Keep the plants watered during dry periods, and fertilize them every few weeks with a balanced fertilizer such as 10-10-10. Harvest your Spinach when the leaves are big enough to eat.
- Spinach can also be propagated by vegetative methods such as rooting stem cuttings or dividing established plants. To take stem cuttings, cut 4–6-inch pieces of the stem from actively growing plants and insert them into moistened potting mix or sand. Keep the cuttings warm and moist until they develop roots, which usually takes 7-14 days—once rooted, transplant the cuttings into individual pots filled with potting mix.
- To divide established plants, dig up the entire plant and carefully tease it apart into smaller divisions, making sure to include a portion of the root with each division. Replant each division immediately in a prepared bed of rich soil spaced 4-6 inches apart.
Best soil for growing Spinach in the USA
The best soil for Spinach in the USA is loose, well-drained soil with a pH of 6.0 to 7.5. It grows well in full sun but can tolerate some shade.

When growing Spinach in the USA, it is important to keep the soil moist. Water Spinach once or twice a week, depending on rainfall and temperature. In hot weather, Spinach may want to be watered more frequently to prevent the leaves from wilting. Apply a layer of mulch around plants to help retain moisture and control weeds.

Spinach season in the USA
When it comes to Spinach, there are two growing seasons in the United States: spring and fall.

- Water Spinach plants regularly, especially during dry periods. Mulch around plants to help retain moisture.
- Harvest baby Spinach leaves when they are 3-4 inches long and mature Spinach leaves when they are 6-8 inches long.
- Cut leaves from the plant using scissors or a sharp knife, careful not to damage the plant. Harvesting every other day will prolong the productive life of the plant.
Spinach growing problems and their control
One of the most common problems when growing Spinach is bolting. This occurs when the plant produces a flower stalk to produce seeds. When this happens, the leaves of the plant become tough and bitter. To avoid this, plant your Spinach in an area with full sun and well-drained soil. Another problem that can occur when growing Spinach is leaf spots. This is caused by a fungus that attacks the plant leaves, causing them to turn brown or black.
To prevent this, clean water plants at the base rather than above. Additionally, you can use a fungicide to protect your plants from this disease. Finally, aphids can be a problem when growing Spinach. These small insects suck the sap from the plant’s leaves, causing them to turn yellow and eventually die. To control aphids, you can use an insecticide or release ladybugs into your garden, as they are natural predators of these pests.
If you notice that the Spinach leaves are changing color, this could be due to several reasons. For example, if the leaves turn yellow, this could be a nutrient deficiency, such as a lack of nitrogen. Alternatively, if the leaves turn red or purple, this could be due to exposure to cold temperatures or too much sunlight. If you’re unsure what is causing the coloring change, it’s best to consult with a gardening expert.
