I'm not certain but I think it was a topic of discussion some time ago and decided that the comments section for each plant would be the place to share our growing conditions for the particular plant. It's also helpful if each commentator mention location where we live (part of the country) to be helpful to others in that area. It sure would be helpful for folks to list the area of the country/world where they live and garden; pruning time is much different for me here in central Florida than for someone farther north.
