Old Cobblers Farm™ Wicked Growth Tubers & Rhizomes Fertilizer

Give your underground crops the nutrition they need to thrive with Old Cobblers Farm™ Wicked Growth Tubers & Rhizomes Fertilizer.

Specially formulated with a 10-20-20 NPK ratio, this fertilizer provides the balanced feeding required for root-based plants like potatoes, garlic, onions, yams, ginger, turmeric, and more. Its targeted blend supports strong root development, plump tuber formation, and resilient above-ground growth.

Unlike general-purpose fertilizers, this formula is designed with a focus on underground crops. With moderate nitrogen (10%), plants gain healthy leaves and stems to power photosynthesis, while higher phosphorus (20%) fuels root expansion and tuber initiation. Elevated potassium (20%) further enhances size, texture, and overall harvest quality, ensuring bountiful yields season after season.
