Granular fertilizer or water-soluble fertilizer—which is more practical?

Spring is the season for fertilizing flowers. Many plants and flowers require substantial additional nutrients to grow vigorously and bloom abundantly. Potted plants begin their annual growth cycle in spring, when their root systems absorb large amounts of nutrients from the soil to fuel development. Since roots primarily draw nutrients from the soil, if the soil's nutrient reserves are depleted, plant growth will stall.
To stimulate growth and flowering, supplemental fertilization is necessary. From spring through summer, fertilizer application is typically frequent, especially for high-flowering varieties that require continuous, substantial top-dressing—sometimes as often as weekly. Only with ample nutrients can plants achieve accelerated growth and abundant blooms.
Regarding fertilizer selection, options are diverse and often a matter of preference. Some prefer granular fertilizers, while others favor water-soluble types. Both forms can effectively support plant growth, but it's important to note that fertilizers in different states can have distinct effects on plant development.
Granular and water-soluble fertilizers differ significantly. Commercial granular fertilizers are predominantly slow-release types. When applied to the soil surface, they gradually permeate and dissolve, releasing nutrients at a relatively gentle rate. While effective for maintaining plant health, they typically lack the ability to significantly accelerate growth. Slow-release fertilizers are therefore more suitable for foliage plants.
For routine plant care or during autumn and winter when growth slows, slow-release granular fertilizers can be used. Spread the granules evenly over the soil surface. With subsequent watering, the granules gradually dissolve into the soil and are absorbed by the plant roots. This dissolution process is relatively prolonged, potentially taking one to two months for the nutrients to fully permeate the soil.
For water-soluble fertilizers, dissolve the fertilizer in water and apply it using a spray gun on the plant leaves or directly water the roots with a spray bottle. Once the water-soluble fertilizer penetrates the soil, it is efficiently absorbed by the plant's roots. This method yields relatively noticeable results and can promote plant growth and flowering within a shorter timeframe.
