Extremely helpful and informative
I spoke to Dan Johnson who was not only extremely knowledgeable but also very helpful with regards to what I might have in my garden. What was also impressive was that he wasn’t just trying to get me to pay for something I didn’t need and was extremely honest so thanks Dan very much!!
