You may never see it in its full glory, but plant another tree. Make sure that what killed your tree wasn't a soil-borne disease first (I doubt it). Maybe a different species. I love the idea that we plant for generations to come. I know that isn't much consolation.

I bought some stone pine seeds last week. They're stratifying in the fridge at the moment. Stone pines are the trees you see all over Italy, in Rome, Pompei and Sorrento. I'll be at least 95 before I see any pine nuts from them, but I'm having a go anyway. I'm not sure that Mrs Steve can countenance another thirty years...
