Hi All!
 
Does anyone know a good weed-spray to use on thistles?
 
I purchased some acreage and wish to kill off the thistles before they
get a grip on the land - but I have bees on the property.
 
There's 35 acres to spray, which is a large job for me to do by hand,
but I'd rather spray the sprouts individually than loose any hives.
 
Thanks for anyone's advice on this issue,
