Do hosta roots grow beyond their leaf canopy?
I grow my hostas under spruce and pine trees but I haven't used any barriers for tree root encroachment. In the past extra watering seemed to do the trick and my hostas thrived although they grow more slowly and don't get as large. However, with the drought most of us are experiencing the trees have been getting the bulk of my extra water. What I'm contemplating is shovel pruning the tree roots around the circumference of the hosta canopies and I would like to know from those who have moved hostas, do the hosta roots grow beyond the circumference of their leaf canopy? Because if they do then I would be cutting into hosta roots and retarding their growth even more. Any advice would be very much appreciated.
