    The product is extraordinary. I am going to place my 3rd order for it already. I am using it for both the thuja-type trees and a silver fir. Since the first 2 uses the effects have been seen: no dry areas for the tuia and the fir tree has very quickly developed new needles. I highly recommend it! Another plus – the order arrives very very fast!

    a concentrated, quality product worth administering to the conifers in our gardens! The bottle comes with a stopper with graduations for dosing the solution; I find this very practical, and on the back of the bottle there is a label with instructions for administering the product in Romanian. Thanks to the team, for their professionalism!

    A very good product, I highly recommend it. I use it for two emerald tujas grown in pots on an open balcony. I’ve had them for 5 years now and at first I had problems with the yellowing and browning of the needles, they were often attacked by various fungi. Since using Fir Fluid the trees look spectacular, they have regular new growth of deep green, they are bushier and don’t get sick as easily as before. I use it from early spring until the first frost in October-November.
