foliar fertilizer can help your plants grow faster and larger. Foliar feeds should be selected based on the plant you are growing. For example, a fertilizer formulated for roses will not be good for a rose bush. Alternatively, a fertilizer formulated for lettuce plants will not be good for a pepper plant. All foliar fertilizers should clearly list their ingredients so that you know exactly what they contain and when they should be applied. If you're unsure of which type of product to choose, the staff at the nursery will be able to help you decide which is best for your specific plant.
