Fertilizer for container citrus
I have been reading this forum and started growing potted semi-dwarf citrus a year ago. What fertilizer would you say is the best for potted citrus? I've seen some conflicting opinions regarding brands and I have learned that spike are bad. However, I am looking for fertilizer specific to container grown trees. Also, I know that watering tomatoes and other vegetable plants with Epsom salt is good for them, does this apply to Citrus as well?
