Clean Plant Propagation
Clean, healthy, and vigorous nursery plants help de-risk the process of establishing new ground
We propagate and sell disease and virus free, true-to-type rootstocks in a variety of specialty crops to nurseries and growers worldwide.
Our University-based plant micropropagation technologies provide our customers with the best plants possible in the shortest amount of time. National Clean Plant Center (NCPN) sourcing plus our rigorous testing program ensures the highest quality material.
Our micropropagation and greenhouse production systems are scalable to meet even the largest orders by nurseries and growers.
Virus Screened and Grown Clean
We start with material sourced from the NCPN whenever possible, and all our material goes through comprehensive virus screening and microbial indexing. Carefully protected from infection and grown to spec in our state-of-the-art Dutch technology based greenhouse, you receive plants that are robust and ready to thrive.
DNA Level, True-To-Type Tested and Confirmed
You get what you order. Qualterra plants are genetically confirmed to be true to type, and the active management features of our TreeTracker™ software protects plants from mixups, so that you receive a uniform batch of correct plants.
Scalable to Meet Large Volume Orders
With our versatile system and trained specialists, we can adapt to your needs! Whether you need a large order of one rootstock for a new orchard, or a small number of different varieties for a breeding trial, our production team can accommodate your request.
