Citrus are hungry plants and our seaweed plant food is perfect for regular feeding. To use, fill the atomiser with water, carefully add five drops of plant food and shake. Mist the base and the stem during the growing season (March to September) once a week. Each set contains 100ml of natural plant food, designed to last for around a year. Made 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.
