Bailey Nurseries in St.
Paul roots over 9 million cuttings every year.
This includes a portion grown from tissue culture.
These micro-cuttings started in January are the Syringa vulgaris hybrids (frequently called the French hybrids lilacs). These micro-cuttings lilacs are shipped to Minnesota from a tissue culture laboratory in Oregon.
Minnesota in winter is not the ideal place to root micro-cuttings in a greenhouse.
Cold temperatures, low humidity, and low light conditions make rooting cuttings a real challenge.
The current method, which uses small tents to better control the environment, yields variable results, and the cuttings require a lot of labor to maintain.
