Reusing Drainage Water from Carnivorous Plant Pots

A grower asks whether water that drains from fertilized Sarracenia hanging baskets can be reused on other carnivorous plants.

Do Not Reuse on Carnivorous Plants

If you’ve applied fertilizer (e.g., dilute MaxSea), the runoff contains nutrients that will harm other carnivorous plants adapted to nutrient-poor media. However, this water is excellent for acid-loving ornamentals like rhododendrons, azaleas, and potatoes.

Fertilizing Sarracenia

Most upright Sarracenia catch ample insects outdoors and rarely need fertilizer. Fertilizer benefits seedlings and poor trappers like S. psittacina, S. purpurea, and their hybrids (e.g., ‘Scarlet Belle’).
