Now, I thought I could use the rabbit feed which is mainly alfalfa in
my garden. But now there is mention of copper being a root killer.
I remember when I read the label on the feed it said (not to be used
for sheep as it contains large amounts of copper).
Does this mean I can't use it? I was going to use this for the alfalfa
watering someone said they used.
