We are committed to providing the largest selection of the highest quality, American-mined, bonsai aggregates in the world. All of our UltraAgg components are US sourced and truly ready-to-use out of the bag - no washing, no drying, no processing of any sort, giving you more time for bonsai.

ULTRAAGG DATA: Learn more about our high quality aggregates, particle size classification system (ie #20 Mini), as well as the properties of each UltraAgg component.

We now offer our aggregates in a more cost effective, as-is and unscreened solution. By selecting the "As-is and unscreened" option, the aggregate will be unprocessed and may have fines and/or moisture.
