ِDear Expert Thank you for useful information in this site, I have a question about organic-inorganic compound fertilizers, are they useful for landscape plants, especially conifer deciduous and flowering plants? and if so, when and how much can they be applied? and I also need some references for mineral needs of landscape plants.I appreciate your response.
Outside United States
Where are you trying to grow your plants? Is it in the United States somewhere?
