UPM’s tree nursery in Joroinen, Finland, celebrates its 30th anniversary this year. The tree nursery will keep an open house for visitors between 29 July and 1 August from 10 am to 4 pm daily.
Founded in 1980, UPM's tree nursery annually produces 14 to 15 million spruce seedlings and forest planting material for the company’s own forests and its customers. UPM's tree nursery produces healthy, high-quality tree seedlings suitable for different areas. All plants are of Finnish origin.
The tree nursery employs 30 people specialised in producing tree seedlings. "Modern plant production technologies combined with skilled staff enable the best possible start for a new forest", says manager Anne Immonen.
"In a good plant, both the stem and the root are of high quality. A healthy plant, successful handling during transportation and storing as well as good soil preparation are all necessary in order to create a productive forest. A careful planting of the tree seedlings is very important", Immonen points out.
Two thirds of forest regeneration is done by planting tree seedlings. Tree species is chosen based on the soil type. Trees are planted at specific spots within a certain distance from one another. In addition to manual planting done by forest workers mechanical planting is increasingly used.
