Dan was employed to cut the grass, trim the hedges, help with the vegetable garden, etc. His business was grass cutting and garden maintenance. (I wonder if he still has any of his other clients or if the Chateau has taken over ?). It soon became clear that Dan was hardworking and capable and more importantly will turn his hand to many other things, landscaping, plumbing, bed crown fixing, filming, catering, etc. Fanny took full advantage of this and utilised his many skills to her benefit. He was available, English speaking and local. I don't believe that Dan ever claimed to be a horticulturist or arborist but he was willing to have a go at whatever his employer asked him to do. We know that she expects everyone to go over and above their skill set - even Pathetic Petherick became her hairdresser and we all saw how that went, until thankfully, Annalise was able to put the damage he caused right. Amaury seems to also be on call for far more than carpentry duties, Ian doubled up as bread delivery service and FRK was assigned to cook for the B and B and produced the most unappetising fare imaginable. Selmar was employed as the handyman but mooched around, muttering to himself and Phiphi was the social media manager and cameraman/editor, who doesn't seem able to manage or film or edit adequately.
Davy and her collaborated on this ridiculous Versailles extravaganza and they expected that Dan would be able to achieve all that they dreamed of. Davy was the designer and drew up the plans. He devised the planting and schedules of work but as other have already observed was missing when it came to implementing and overseeing the work. (Very similar to Phiphi in that respect.) I thought that Davy was project managing the garden plans - why else is he back and forth? I assume that the reason for that particular visit was to coincide with the delivery of the trees, etc.
I'm not sure. that Davy has any real credentials for this - I think it was
@Le Comte de Monte Cristo who said that he was unable to find any trace of Davy's professional career? Does he "design" his gardens with his playmobil kits and seed catalogues? He's another strange member of the Lalande community.
In many ways, I hope that the trees don't establish - it will be one more example of how funds are mismanaged.
