Thank you! That's good to know. We just finished burying our duck about an hour ago (we needed closure). We ended up burying it about 6-12 inches from the drip line (or, what I assume is the drip line, since that was how far the foliage went out) from our Persian mulberry. The mulberry is only two years old and hasn't started fruiting. We were only able to bury it
maybe two feet under, as the ground was hard. With me being pregnant and my husband just having had surgery, we really couldn't dig as deep as we like. We added some pine shavings in hopes of it speeding up decomp and absorbing some of the smell.
It's reassuring to know that we probably buried it deep
enough and a good distance from the tree! Thank you!
