BRIEF: Does black locust wood affect horses?
QUESTION:
I was wondering if Black Locust fence posts would be a problem when fencing in
horses? The bark is removed and all posts are "oiled". If the horses chew the
wood would it be toxic? Another quick question...we have some black walnut
trees on this new property and am aware of the sawdust being toxic to horses
standing on it but not ingesting the bark, leaves etc...IF my horses eat the
bark, leaves etc...would this be toxic? I am located in central Wisc.
ANSWER:
The posts should be OK, but what kind of oil?
Horses bedded in black walnut sawdust sometimes have problems, but I am not aware
of much trouble otherwise.
