landscaper did not put plants in ground
My first experience with professional landscaper. Heathers, vinca, nothing exotic. Plant installation: 4 in. up to one gallon plants not planted in soil but barked up to hide root ball. When asked said that was intentional and plants would be fine; anyway there was a one year guarantee. I've never heard of not planting plants INTO the ground. Is this OK? Also this was week of early March overnight freezing- is that going to add insult to injury?
