We can tell you how the TFI method works, but we’d prefer to let our customers do the talking. Below you will find several testimonials from our customers about their experiences with TFI.

Alleviating Soil compaction
” In spring 2013, we seeded new lawn and planted boxes with roses and trees between the road and sidewalk. Of the 30 trees we planted, 10 died. We replanted and again lost seven of the replanted trees. The cause was clear to me: stagnant rainwater. We had a bit of rain and a number of pieces of the ground were underwater for several days.
In November, 2014, TFI performed a soil compaction alleviation treatment. What a difference it made! Normally after a little rain, the lawn and planted areas stand underwater for days. Now after nearly four inches of rain the area was passable again after just one hour!”

Habitat improvement / Pest control
“In 2012, Brunssum used TFI to improve the habitat of 14 monumental sycamores. The first year, there were few noticeable effects from the habitat improvement. However, last year, as promised, the effects were clearly visible!
The trees have better leaf coverage and beautiful color. In the past year they have had significantly fewer issues with Massaria and Gnomonia “leaf spot disease” and this has resulted in less maintenance.
In a stand of linden trees that we have also had treated against aphids by TFI, we have experienced good results and no more nuisance complaints from the residents. ”

Habitat improvement
“In our town there are 18 linden trees that, for 10 years, have experienced stagnant growth. We were about to replace them in 2013 when TFI4000 advised us to give their habitat improvement method a chance. The response of the trees to the TFI method was really impressive. The trees suddenly grew so well that after one season the frost / burn from recent years was almost completely overgrown. Also this year, the trees are developing further and they look beautiful.
Thanks to the TFI method, these trees are not only no longer slated to be replaced, but they are a solid foundation for a beautiful new avenue. ”

Alleviating Soil compaction
“This morning I understood from my colleague in the field that, through the use of the TFI method conducted three weeks ago, both the cemetery in Zeewolde and the trees along the Quartermaster Hitting have seen a positive moisture effect.
In the areas where the TFI method was applied there is either less water than expected or no water at all on the surface. It also rained in Zeewolde yesterday and Friday a lot!! We continue to follow it.”

Pest control
“We had in the past many louse infestations in some linden trees on the Brink in Den Ham. In 2009, we allowed these trees to be treated by TFI. The results in 2009 and 2010 were so satisfactory that the following spring the whole community had 64 problem trees treated. This came with a 3 year warranty.
In the growing seasons of 2011 and 2012 in the neighborhoods of the treated trees, we have received no complaints of louse infestations.”

Reducing shallow root growth
“We had many years of trouble with shallow root growth causing pavement upheaval on the bike path to Thorbeckelaan. Uneven tiles caused by the roots of tree stands between the road and the bike path caused dangerous conditions! To prevent this, we had to annually remove roots and replace spots in the pavement. Ultimately for us, this was for us crazy and expensive and we began to think about removing the trees. Luckily we came into contact with Gert Veldhuizen of TFI4000. He convinced us to tackle these problems differently. It has been five years since we decided to treat the trees using the TFI method, and the pavement, which we re-established for the last time after the treatment, is still good! In the next few years, I had expected to see a lot of shallow root growth at this location, but this has not happened. Additionally, we have been able to preserve the trees and they are doing even better. In short, this is a success that we have already repeated at various other locations and we have great satisfaction in collaborating with TFI! I would therefore like to thank the TFI method and the TFI4000 company who are currently my colleague’s for all that they have done to address shallow root growth.”
