This post is about figs and chestnuts were only mentioned to explain I was too busy to reply. But you persist, so... ;)
Marcel, I grow Castanea sativa, specifically Italian marroni varieties. You can read more at chestnuts.us We don't have blight near here although one orchard grown about 50 miles away did have the disease (don't know if it has been removed or not). In our arid climate it has never been much of a problem, partly because of the climate and also because there aren't many chestnut trees for it to be spread to. More walnuts, almonds, winegrapes, etc.
Tony, having some woods to take the burs to is a nice thing. I mentioned "urban setting" and most folks in urban settings don't have a place to take the burs to. I suggest Best 7066 (smooth) gloves instead of leather gloves, though the spines on the burs of some species are less lethal than others. I think no matter what I do some spines are also going to get tracked into my house on my shoes, pants leg, etc. I think this is worse in arid climates. I survive to tell about it.
I have many hours of work left tonight and will not discuss chestnuts further in this thread. Thanks in advance for understanding!!!
P.S. This thread is a good example of why I post mostly on my Facebook page. I delete comments that derail a topic I post about. :)
