What Is the Best Foliar Fertilizer for Flowers? A Detailed Guide to Buying Tips

For flowers, it is best to use nutrient solutions or compound liquid fertilizers containing elements such as nitrogen, phosphorus, potassium, iron and zinc. During the vegetative growth stage, flowers can be sprayed with a foliar fertilizer containing nitrogen fertilizer, which must be diluted with water, and the concentration must not exceed 5%; during the reproductive growth stage, a foliar fertilizer containing phosphorus, potassium and boron fertilizers can be sprayed, such as a mixed spray of 0.2% monopotassium phosphate and 0.1% boron fertilizer solution.
