Experimental trials on fir and pine trees were held from the 15th - 18th December at Spruced's Robertson nursery. The work was done in collaboration with Bjarke Veierskov, a visiting Professor of plant physiology from Denmark. The experiments looked at growth regulation and stimulation of various Christmas tree species with plant hormone treatments as well as comparing the greening effects of another hormone against more traditional fertilisation methods. Data collection is ongoing and will hopefully lead to some useful insights on the trees and contribute new scientific knowledge to the international Christmas tree industry.
