The answer to 'which is better organic fertilizer or synthetic fertilizer' is that both organic and synthetic fertilizers have their advantages, and the best choice depends on your specific gardening needs and preferences. Organic fertilizers are made from natural, renewable sources like plant or animal materials, while synthetic fertilizers are manufactured chemically.
Organic fertilizers tend to release nutrients slowly over time, improving soil health and structure. They are generally safer for the environment and can be better for plants in the long run. Synthetic fertilizers act more quickly to provide an immediate nutrient boost, but they can deplete soil quality over time if not used carefully. Synthetic options are often less expensive upfront, but organic fertilizers may save you money in the long run by improving your soil.
