Iron in plants and soil

Iron is most available to plants when the pH of the soil is 7 or lower though most plants should be able to uptake sufficient iron if the pH of the soil is 8 or lower provided other essential elements are well balanced. If the soil is too alkaline, it is especially important to lower the soil pH if you're growing acid loving plants.
