Use this 0:10:10 fertilizer for newly transplanted Bonsai trees.

Formulated without nitrogen so it doesn't promote foliage growth, this formulation still provides a balanced delivery of phosphorus and potassium to keep your Bonsai tree's root system healthy and happy.  A great product and a bit hard to find.  Imported by Joebonsai from Japan.

This is an 8 ounce bottle.  Mix 2 teaspoons in one gallon of water and apply every two weeks.
