Spinach’s nutritional information (United States Department of Agriculture, 2013)
Information About Plant
Spinach (Spinacia oleracia) is a green leafy vegetable that has high nutritional values (refer to Figure A below). It prefers temperatures from a range of 20-23ºC and an environment of about 6.5-7.0pH (acidity). It prefers a mild climate and will not do well in very warm temperatures. It has a preference for direct sunlight (Bonnie Plants, 2013). It does not have deep roots and do not thrive well in environments that flood regularly. Spinach is a nitrogen-hungry crop, and overwintered plants in particular benefit from booster feedings with a water-soluble fertiliser (Pleasant, 2010).
Ready-to-harvest spinach have leaves that are 7-10cm in length and 5-7cm wide. It takes about 6-8 weeks from the time of planting to harvesting. One can harvest the spinach by removing the outer leaves through shears (Organic Gardening, 2013).
