Fern plants like to stay damp so it is important to mist regularly with water. To use, fill the atomiser with water, carefully add eight drops of plant food and shake. Mist over the leaves during the growing season (May to September) once every 2-4 weeks. Each set contains 100ml of natural plant food, designed to last for around a year. We make our plant food using nutritious seaweed harvested from a nearby beach. Seaweed is a wonderful fertiliser because it is rich in nutrients and carbohydrates, helping your plants to grow strong and healthy.
