Diabetes affects our blood vessels and nerves and therefore can affect any part of the body. However, certain parts of our body are affected more than other parts.
I don't think dogwoods have (much?) scent, maybe just lightly floral. The white petally looking things are not actually petals they are bracts, like a poinsettia has. There's something called an English dogwood that is very fragrant, but it isn't a true dogwood and is also known as mock orange. Bradford pears have a smell that this author described as sweaty socks, so if your tree doesn't smell very good that's probably it: http://www.gardenguides.com/106133-dogw ...
Prune dogwood trees to remove dead or diseased branches during the dormant season. Control plant shape or height by pruning right after flowering in the spring. Spray cuts with Lindane insecticide to avoid infestation of Dogwood borer.oth drought and poor drainage can cause dogwood trees not to bloom. Pacific and kousa dogwoods are more tolerant of drought conditions than flowering dogwoods. Provide 1 inch of water per week to young dogwood trees up to six years old. Dogwood tree roots are shallow.
