Superthrive Bonsai Vitamins & Hormones
Superthrive has been around since 1940. It actually won the World Fair Science-Medal. Full of vitamins and hormones that plants (and bonsai) love. It is commonly used on bonsai during re-potting to promote root growth and reduce stress. Many bonsai practitioners also use it as a foliage spray to bring their trees to the next level by introducing vitamins to the foliage.
Superthrive is used in addition to bonsai fertilizer for the ultimate in healthy plants.
