This leafy edible green originated in central and southern Asia but has luckily spread to gardens worldwide. A cool season annual, spinach usually grows best when temperatures stay below 75°F. Mature plants can survive lows down to 20°F: perfect for overwintering. Harvest the richly flavored oval- to triangular-shaped leaves for a treat in salads or as a cooked green and get pumped like Popeye! When plants begin to bolt, they will send up flowering stalks with small greenish-yellow flowers, and leaves will develop a bitter flavor. So make sure to harvest your sweet leaves before this happens!

Verdil is an open-pollinated, smooth-leafed spinach with large, green-colored leaves. It grows quickly and needs a good amount of space. Due to its cold tolerance, it’s a good choice for planting in the fall for overwintering or in early spring. Verdil does poorly in summertime heat, but if grown in cooler weather, its strong tasty flavor is ideal in salads.

Prefers a mild climate and cool weather. Spinach is quite hardy and can withstand temperatures as cold as 20°F but prefers temperatures between 50–65°F. If you live in a cooler climate zone and are planting very early in the spring or overwintering your crops, cover with straw to keep plants protected in case of extreme cold snaps. If planted too late, your plants may come to maturity when it’s too warm, and they’ll likely bolt quickly and become bitter.


Natural: Full sun. Partial shade in warmer weather.

Artificial: Fluorescent bulbs are a good choice for spinach plants as they don’t care for too much heat.

Growing Media

Soil: Will grow in most soil types but prefers a slightly sandy substrate. A pH of 6.0 to 7.5 will keep plants healthy and nourished.

Soilless: Seeds will germinate in most soilless mixes and prefers those that are higher in nitrogen.

Hydroponics: Will thrive in hydroponic systems in media such as coco coir or perlite.

Aeroponics: Will thrive in an aeroponic system.


Water: Requires low to moderate amounts of water but likes soil that is evenly moist. The highest amounts of water will be required when plants are still in their younger stages. This can be lessened as the plant matures.

Nutrients: Requires moderate levels of nutrients. A balanced fertilizer of nitrogen, phosphorous, and potassium is preferred. Choose mixes that have higher amounts of nitrogen and potassium and lower levels of phosphorus for preparing the beds prior to planting.

Foliar: Apply compost tea or fish emulsion when plants have first been transplanted, about a month following, and just prior to harvest.



  • Caterpillars
  • Flea beetles
  • Leaf miners
  • Wire worms


  • Downy mildew
  • Leaf spot
  • Mosaic virus
  • Root rot

Deficiency(s): If leaves are turning yellow, your soil pH may be too high. Adding limestone to your soil can reduce the pH. This may also occur if there is a nitrogen deficiency.

Rotation and Companion Plants

Rotation: Do not follow legumes with spinach. Most crops like being planted after spinach since it’s not very susceptible to soil diseases.

Companions: Grows well with members of the cabbage family, strawberries, fava beans, celery, lettuce, onion, eggplant, and peas. Avoid potatoes.

Harvest and Storage

Harvest: Leaves may be harvested throughout the growing season, but avoid harvesting before the plant has produced approximately 4 to 6 leaves. When ready to pick, start with the outside leaves, allowing the middle leaves to develop. The plant may be harvested all at once as well by cutting at the base of the plant just above soil level.

Storage: As with most leafy greens, leaves will not keep for much longer than a week in the refrigerator, so if planning on consuming them fresh, pick just before you are ready to use them.

Other Info

Fun Fact: This spinach variety was first developed by Bingenheimer Saatgut, a German biodynamic seed company.


Preserve and Prepare

Preserve: May be blanched and frozen for later use.

Prepare: Is commonly consumed raw in salads but is also delicious (and healthy!) sautéed, boiled, or steamed.


Nutritional: Is rich in vitamin(s) A, B, and C as well as many minerals including iron, magnesium, manganese, and folate. Also contains trace amounts of calcium.

Medicinal: Some studies have shown that, due to its high content of folate, spinach can assist in reducing high blood pressure and contribute to improvements in overall heart health.

Warnings: Like chard, spinach contains oxalates which can crystallize and form painful urinary tract stones, so individuals suffering from this condition should consult their doctor before consuming large amounts. Take note that the level of oxalates in spinach can be reduced by cooking.
