Laguna Plant Grow Once-A-Year Fertilizer Pond Spikes supply important nutrition to aquatic plants for one full year. The temperature-activated feeding sticks release nutrients only when plants need them most - at or above 50 degrees. Once activated, the spikes slowly release a well-balanced feeding formula that maximizes the size and color of all potted aquatic plants. Also compatible with all planting boxes.
Push the spike in the soil until cap is just above soil surface. After one year, discard the spike as the fertilizer inside the spike no longer contains nutrients. Use one spike for 1 or 2 US gal or 4 or 8 L planting baskets. Use 2 spikes for 3 US gal or 11 L planting baskets. Use 3 spikes for 4 1/2 and 5 US gal or 17-18 L planting baskets. Use 4 or more spikes for 5+ US gal, or 18+ L planting baskets.
