Clean Plant Propagation
Clean, healthy, and vigorous nursery plants help de-risk your operation
We propagate and sell disease and virus free, true-to-type horticultural and ornamental plants to nurseries and growers worldwide.
Our 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.
A Clean Start for Vigorous Plants
We provide virus‑free, disease‑screened rootstocks and plant material across a wide variety of specialty crops – ideal for orchard expansion, varietal trials, or ornamental nursery production. Backed by micropropagation technologies, we can quickly scale up clean starter material, carefully protecting it from infection throughput propagation and finishing.
- Sourced from National Clean Plant Centers whenever possible.
- Every line undergoes comprehensive virus screening for agronomically relevant viruses – our screening panel can detect over 2,600 viruses and viroids – to ensure it arrives disease‑free and ready for success.
- Micropropagated lines are indexed for bacteria and fungi, allowing us to rogue out lines with harmful endophytes.
Verified Genetics and Reliable Products
Uniformity, accuracy, and traceability matter – whether planting a commercial orchard or a small-scale breeding trial.
- Careful management of growth conditions supports even, predictable growth
- TreeTracker™ inventory management software actively prevents mix‑ups throughout micropropagation
- Our DNA-level genetic testing confirms every rootstock is true‑to‑type.
Greenhouse‑Grown Plants are Robust and Ready to Thrive
Our state‑of‑the‑art Dutch‑technology greenhouse ensures all plant material is grown under optimized conditions and protected from infection, to ensure strong plants that establish rapidly.
- Fruit trees:
- Faster establishment in orchards helps them reach fruiting 30–40% sooner with minimal mortality
- Plants reach grafting caliper quickly.
- Ornamentals:
- Strong, uniform plants that finish quickly for sale or installation
- Custom and confidential propagation services available to serve a wide variety of crop systems
- Deep, healthy root systems are encouraged by our “conetainer” system – crucial for orchard establishment, landscape performance and retail presentation
Scalable Production to Meet Your Needs
Whether you’re planting a large‑scale orchard or fulfilling diverse ornamental orders, our production system adapts to you.
- Large‑volume orders for commercial growers
- Smaller, multi‑variety lots for breeders, trial blocks, or nursery production
- Reliable availability across many specialty horticultural and ornamental crops
Plant Specification Options
Offering Plants in Multiple Formats
Greenhouse-grown plants: Our greenhouse-grown plants are clean, vigorous, and ready to plant or finish. Careful control of their growing conditions ensures that they are uniform and robust.
- Liners (128, 72, 32, or 36 cell)
- Potted plants (4”, 2qt, 1 gallon, 2 gallon)
- Bareroot dormant
Rooted Micropropagated Plants: Our micropropagated plants are grown in proprietary aseptic medias. They are ready to be transferred to potting mix and acclimated to environmental conditions. This system delivers the cleanest plants possible; they are easier to export to regulated regions than their greenhouse-grown counterparts; and they are an economical option for customers that are prepared to handle them.
