Why Iron EDDHA
- Plants with iron deficiencies will have pale yellow leaves and will not be able to produce the sugars requried to grow. Iron EDDHA fixes this issue, allowing for iron uptake (Wiersma et al. 2019)
-
Unlike other iron sources which only work in low pH solutions, Iron EDDHA is effective up to pH 10 (Lucena et al. 2006)
Ingredients: Iron EDDHA powder
How to use:
Foliar spray & watering: Mix 5 Teaspoons per liter of water and use either as a foliar spray or water directly into soil/media* (solution will have a red color)
*Iron is not able to be moved into existing leaves from the soil so foliar application is necessary for existing growth, while watering into the soil will support new growth.
