Q.how to fix iron deficiency
I have several camellia and gardenia plants that have green veins and yellowish leaves. Research tells me it is an iron deficiency. I am looking for the best product to use to correct this deficiency. I live on coast of California in a damp summer environment. Thanks.
This normally happens either when the plant is watered too much and the nutrients get leeched away or if the pH is too high. Test the soil and correct and nutrient and pH issues found when testing. Also, make sure that the soil is not too porous and is letting the water run away too quickly.
