Over the last 5 years, First-Tree B.V.has provided plant growth regulators to some of the most prestigious names in the global horticulture business, from bulb and flower growers, nurseries and plant propagators to soft and stone fruit growers including research institues.

Established in 2016, the independent company based in The Hague, the Netherlands is overseen by a management team having broad experience in innovative projects, along with a global network of contacts.

First-Tree’s approach is transparent, friendly and straight. Its plant growth regulator provides tangible, independently verified results at an affordable price that many larger companies struggle to match.

From its inception, First-Tree B.V.has worked to create a more sustainable, organic and fair horticulture. Previously, there was little talk of considering social or environmental impacts in horticulture. Today, horticulture, with its power and ability to naturally feed us all and decorate our homes and gardens, is on the front line of creating a fairer, more inclusive society.



Short story about First-Tree
Prior to founding First-Tree B.V., its founding father developed a solution containing nano-size nitrogen bubbles which appeared to stimulate growth and flowering of plants. Since the solution had to be made fresh on site using a large pressure vessel, to turn this into a viable business was a challenge to say the least. This prompted the quest for a product having similar growth stimulating effects as the bubble solution, during that period we got into contact with a professor in Austria who had more than 20 years of research experience with various plant extracts having just those properties. From there on and on the basis of a technology exchange, a strong working relationship was established that served to improve our understanding of the material we are still working with.

Our first pilot was with a farmer in Wieringerwerf, the Netherlands on a small patch with tulips where, after lifting and sorting the bulbs, we observed a jump in size. Those results opened many doors including that of G. Geerlings en Zonen B.V. (now Dümmen-Orange) where we treated a couple of beds of Calla tubers. Based on the results all first year Calla tubers are now treated with the GOOD FOR GREENS® plant growth regulator.
