Our cultivation begins with tree seeds. We purchase seeds ourselves, or customers supply us with seeds that we then clean and stratify. <\/p>

In the spring, the seeds are then sown automatically into styrofoam trays. This process ensures even distribution and a consistent start for every plant, laying the foundation for uniform cultivation. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

After sowing, the trays are placed in 4.5 hectares of foil tunnels or roll-air greenhouses. Here, the seeds receive optimal conditions to germinate and develop rapidly. This phase is decisive for a strong and healthy start. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Once the plants have reached sufficient height, the foil is removed from the tunnels. This exposes the plants to natural conditions, allowing them to develop further. This process ensures strong, thicker, and robust plants that are well-equipped to withstand transport and transplanting. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

From February to June, delivery of over 50 different types of plug plants takes place throughout Europe. A portion of the 1-year-old plug plants is transplanted by us into P40 trays for the production of 2-year-old plants a season later. We grow these 2-year-old plants on a 0.5 ha container field. <\/h5>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Spring sowing<\/strong>: a small portion of our assortment is sown in February and March and grown in a heated greenhouse for delivery in May\/June of the same year. This is done with plant species that customers prefer to pot fresh, or when there is a need to shorten a cultivation year due to a shortage of a specific species. These plants are hardened off a few weeks before delivery to prevent transplant shock. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
