The association was founded in 1984 as a subdivision in the forestry management sector’s society, The Danish Forest Association, but had from the start its own rules and its own board of directors.

The need for such an organisation was developed gradually as it was only a little niche production in the beginning which had grown up until it accounted for a significant and central part of the forestry management’s total earnings. Then came the section more commonly known as "PyntegrøntSektionen" (the ‘decorative greenery section’), and had as its main objective to work with promoting production, marketing and sales of decorative greenery and Christmas trees . As members were among others the majority of large estates in Denmark, and nearly all larger forest properties, had decorative greenery production as a lucrative source of income.

In 1997 the development in the sector gradually resulted in larger and larger differences between the owners, who naturally belong in the Forest Association and those who needed a powerful organisation for decorative greenery production. Therefore, Danish Christmas Trees was estalished to represent the interests of the growers covering both the very smallest to the very biggest Christmas Trees and cut greenery growers in Denmark.

The association published a magazine from the beginning which only had the title PS – an abbreviation of the subdivision’s Danish name. During 1987 Nåledrys was added so the title in future answered to PS – Nåledrys. The abbreviation PS is therefore also seen in several places in connection with the association.
