Crop management:Spinach

Crop managment

Spinach requires high levels of moisture, and if rainfall is inadequate, 2.5 cm of water should be applied every 7–10 days. Spinach also has high requirements for nitrogen and potassium which should be provided by applying fertilizer based on the results of a soil test. Potassium poses little environmental risk and may be applied based on the results of a soil test. Timing of nitrogen applications vary by location as there is a risk of leaching during heavy rainfall. In the home garden, fertilizer is often not required as long  spinach is planted in a fertile soil.
