I'm having a new deck built, so I will loose one spot from my yard where a young Honnef's Surprise cv Grapefruit (Poorman Orange x Grapefruit) is currently growing well. I also have a Meyer Lemon in an unprotectable spot and we have citrus sucking moths and fruit flies that adore the fruit. So I was hoping to graft these and maybe more onto existing citrus, most likely onto a Flick's Yellow Pomelo (hybrid). Does anyone have any tips on the best way to multi graft onto existing plants, where to position them, what method to use, etc? Any advice greatly appreciated.
