Oyster Shell Fertilizer

$ 9.95

Calcium is a component of plant cell walls, and it’s needed for enzyme formation and nitrate uptake. Organic calcium can also be used to help neutralize excessively acidic soils, which is especially important when you’re growing green, leafy vegetables like lettuce and spinach, or cruciferous vegetables like cabbage, broccoli, cauliflower, and kale.

Highest quality ingredients help provide an effective and environmentally friendly approach to plant care, crop fertilization and soil management.
