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 50F (10C)

Once activated, the spikes slowly release a well-balanced feeding formula that maximizes the size and color of all potted aquatic plants.
