We have many hawthorn trees on our property. Is it true that it makes good firewood? Is it true that it burns best within a few months of cutting (versus 1 or 2 years later)?
Hawthorn makes good firewood. It burns hot and long and is a great species for woodburning.
Firewood is always best when it has been properly seasoned and has a moisture content of 20% or less. A few months, unless you live in a very dry hot climate, probably isn't going to be long enough to season the wood adequately.
Hope this helps!
