GardenPRO Superbloom 10-40-25 Water Soluble is a water soluble fertilizer made for bloom-focused nutrition, supporting large, prolific blooms and stronger flower colour in gardens and containers. It’s a soluble plant fertilizer built around a high-phosphorus profile for times when flowering performance is the priority.
Superbloom is chosen when you want a clear, flowering-forward nutrient direction without juggling multiple products. The formula is described as producing large, prolific blooms, making it a strong fit for ornamentals where visual impact matters. It’s also positioned for high phosphorus applications, with benefits that include helping improve flower size and colour when plants are in their blooming phase.
This GardenPRO water soluble fertilizer suits both indoor and outdoor growing, which is helpful if you maintain flowering plants across windowsills, patios, and seasonal outdoor beds. Because it’s water soluble, it fits gardeners who prefer a dissolvable fertilizer format that integrates cleanly into regular plant care, especially when you want a product that stays focused on bloom results rather than broad, general feeding claims.
The facts layer, kept compact: the stated NPK is 10-40-25. In addition to the primary NPK nutrients, the product includes micronutrients, with boron, copper, iron, manganese, molybdenum, and zinc listed in the formula. Several of these trace elements are provided in chelated forms, supported by an EDTA chelating agent, which helps keep micronutrient availability consistent in solution.
GardenPRO Superbloom 10-40-25 Water Soluble is a good fit for gardeners looking for a water soluble bloom fertilizer with micronutrients, especially when the goal is larger, more prolific blooms and improved flower size and colour across indoor and outdoor flowering plant setups.
Indoors: Mix 5 mL (1 tsp) per 4 L of water.
Outdoors: Mix 15 mL (1 tbsp) per 4 L of water.
Use every 2–4 weeks during the growing season for ongoing bloom support.
Apply the mixed solution when watering, soaking the root zone evenly.
