Geothermal heating and plants
Various people have said we should try geothermal heating and husband is keen. It seems we can have a massive bore hole at even more massive expense or we can dig up an extensive lawn and rearrange some borders so we can put hundreds of meteres of pipe in underneath. The engineers to whom I have spoken are engineers first and gardeners very much last. Does anyone know the effect on the shrubs and grass above? It seems logical to me that the ambient root temperature will drop and that could be problematic where we live - but I may be guessing totally wrongly? How much redesign am I in for????
