There is a reason why Baby Bio® has been Britain's favourite houseplant food brand for over 60 years and that is because its formulation makes it ideal for helping your houseplant grow greener leaves and maintain vibrant colours. Baby Bio® Houseplant Food contains the perfect balance of the 3 major nutrients required by your favourite houseplants: • Nitrogen (N) – for healthy, bright green leaves • Phosphorus (P) – for strong roots • Potassium (K) – for better blooms and fruits.
