What are the advantages of water-soluble fertilizers?

These dry or liquid concentrates must be diluted in water before application. They are applied with a hose-end sprayer or a watering can. They are relatively expensive, but they are easy to apply and provide even feeding. They are easy to use, especially on container plants. There is no risk of burning a plant as long as you follow label directions for dilution, and the nutrients, in solution, are available to plant roots immediately. They are less practical than the solids for large-scale use because of their greater cost and because they must be reapplied more often (their nutrients in solution leach through the root zone more rapidly).
