Per-Basket Dosing

1–2 tablespoons per hanging basket — no measuring cups, no sq ft calculations. Sprinkle on the soil surface and water in. Simple enough for anyone.

⚖️

Balanced for Container Life

Hanging baskets need foliage (N), blooms (P), and root health (K) simultaneously in a tiny soil volume. 10-10-10 feeds all three without overemphasizing any one nutrient.

📦

80–160 Baskets Per Bag

At 1–2 tbsp per basket, one 5 lb bag feeds 80–160 hanging containers per application. One bag can last an entire porch for the whole season.

💧

Dissolves for Liquid Feeding

Can be dissolved in water for liquid drenching — helpful for densely planted baskets where top-dressing is difficult to reach the soil surface.

📅

Every 4–6 Weeks

Frequent watering leaches nutrients from small containers faster than garden beds. Reapply every 4–6 weeks to keep nutrition consistent.

🌸

Supports Continuous Bloom

10% phosphorus maintains flower production in petunias, million bells, fuchsia, and trailing verbena — the heavy-blooming plants that define great hanging baskets.

All Hanging Basket Plants

Petunias, fuchsia, million bells, sweet potato vine, ivy, ferns, begonias, trailing verbena, lobelia — every basket plant benefits from balanced feeding.
