Bonsai plants have very little soil in which to grow, it is important to feed them regularly and never allow to dry out. Mist the base and the stem during the growing season (March to September) once every 7-10 days. 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.
