I have 2 trees in my yard that are fantastic shade and the temp drops at least 10 deg when i
mow under them....I have no idea what they are the were planted probably 45 years ago when the new house was built...
Not all trees are good....we have an abundance of honey locust....nasty big thorns flat tires...and we are fighting them in the bean fields constantly.....good fire wood if you want to fight the thorns....really not worth it....
