Spinach Spinacia oleracea 'Amazon'
ABOUT
Spinacia oleracea 'Amazon', commonly known as spinach, features vibrant green leaves that are both broad and tender, characterized by a slightly wrinkled and veiny texture. The leaves are arranged in a rosette pattern, emerging from a central point and creating a circular display of foliage. Each leaf is attached to a slender stem that provides support and facilitates nutrient transport. The edges of the leaves can vary from smooth to slightly toothed, contributing to the plant's overall texture and visual interest. The leaves of this cultivar are typically lush and may appear to have a glossy or semi-glossy sheen under natural light, reflecting the plant's health and vigorous growth habit. During its growth cycle, the spinach may develop small flowers, though they are not particularly ornamental and are often inconspicuous compared to the prominent foliage.

- Toxicity
To humans
Spinach, specifically the Spinacia oleracea 'Amazon' variety, is not considered toxic to humans when consumed in typical food quantities. However, spinach does contain oxalates, which in very high amounts can lead to the formation of kidney stones in susceptible individuals. Additionally, consuming extremely large amounts of spinach could lead to vitamin K overload, which can be an issue for individuals taking blood thinners. Nevertheless, in usual dietary amounts, spinach is safe and nutritious for human consumption.
To pets
Spinach, including the Spinacia oleracea 'Amazon', is generally not poisonous to pets, but it does contain oxalates which can potentially cause problems if consumed in large quantities. Pets that ingest large amounts of spinach might experience digestive upset, or in severe cases, kidney damage due to the oxalates contributing to the formation of calcium oxalate crystals. However, in small to moderate amounts, spinach is typically safe for pets. Pet owners should be cautious and consult with a veterinarian especially if their pets have known health concerns that could be exacerbated by oxalate consumption.

- Water
Spinach requires regular watering to keep the soil consistently moist, but not waterlogged. Water spinach plants evenly with about an inch of water per week; during hot, dry spells, you may need to water more frequently to maintain the soil moisture. It's best to water in the morning to allow any excess moisture on the leaves to dry throughout the day, reducing the risk of fungal diseases. Avoid overhead watering to prevent soil splashing up onto the leaves, which can lead to disease; instead, water at the base of the plant. In terms of volume, this amounts to roughly 0.5 to 0.625 gallons per square yard, per week, under normal weather conditions.
- Light
Spinach prefers a sunny spot with at least six hours of direct sunlight per day. However, it can tolerate partial shade and might even benefit from it in hotter climates where the sun is more intense. The ideal spot provides morning sunlight with some afternoon shade to prevent the plant from bolting in high temperatures.
- Temperature
Spinach thrives in cool weather and can tolerate a light frost. The ideal temperature range is between 50°F and 70°F. It is hardy in temperatures as low as 20°F and as high as 75°F, but growth may be stunted or the plant may bolt if temperatures exceed this range.
- Pruning
Spinach does not require traditional pruning, but regular harvesting of the outer leaves can promote new growth and extend the production period. Pinching off the tips can also delay bolting. The best time to harvest is in the morning when the leaves are most crisp. Periodic removal of damaged or yellowing leaves is also beneficial.
- Cleaning
As needed
- Soil
Spinach 'Amazon' thrives in a well-draining soil mix with plenty of organic matter, such as a blend of loam, compost, and peat with a pH range of 6.0 to 7.0. Aeration and moisture retention are key, and a balanced, slow-release fertilizer can be mixed in to support growth.
- Repotting
Spinach 'Amazon' is an annual plant and does not typically require repotting as it will complete its life cycle within a single growing season.
- Humidity & Misting
Spinach 'Amazon' prefers moderate humidity levels but is quite adaptable and does not require specific humidity controls when grown in a typical garden setting.
- Suitable locations
Indoor
Place in a sunny spot and keep soil moist.
Outdoor
Plant in rich soil, full to partial sun.
Hardiness zone
2-11 USDA
- Life cycle
Spinach (Spinacia oleracea 'Amazon') begins its life cycle when seeds are sown into well-draining soil and germinate, which typically takes 5 to 9 days depending on the soil temperature. After germination, seedlings emerge and enter the vegetative growth stage, developing a rosette of leaves and establishing a root system. The plant matures into this leaf production stage, during which time it can be harvested for edible leaves; in optimal conditions, this can occur within 40 to 45 days. As the plant ages or if exposed to longer daylight hours, it enters the bolting stage, where it starts growing a flowering stalk to produce flowers and seeds. Once pollinated, usually by wind, the flowers produce seeds, completing the reproductive stage. Finally, after seed set, the plant enters senescence and dies, with the seeds ready to begin the next generation when conditions are favorable.
- Propogation
Propogation time
Spring to early summer
Spinach, specifically the cultivar Spinacia oleracea 'Amazon', is typically propagated through seeds. The most popular method of propagation for this plant is direct seeding. The best time to sow spinach seeds is in early spring or fall, as spinach prefers cool weather and tends to bolt in high heat. To propagate, seeds should be sown about 1/2 inch deep (about 1.3 cm) into well-tilled soil that has been enriched with compost or organic matter. Seeds should be spaced approximately 1 inch (2.54 cm) apart in rows that are 12 to 18 inches (30 to 46 cm) apart. After sowing, the soil should be kept moist to ensure germination. Seedlings typically emerge within 5 to 14 days, and thinning is recommended once the plants have a few true leaves, leaving 3 to 5 inches (7.6 to 12.7 cm) between plants.
