My block paved drive is backed by a border containing escallonia and buddleia. I dig hundreds of seedlings of both out of the drive, but never find any in the border. Does anyone know a better reason than sod's law why they germinate so readily in crevices and not in soil?
The pacing slabs retain heat and stop the soil drying out so much I suppose.
If I see a seedling I like the look of, I try to ease it out. It works -sometimes
