pecan leaves OK for composting??

vieja_gw(z7NM)November 17, 2007

I compost all our tree leaves (fruit trees, mulberry, ash)into our gardens but was wondering if I could also use the leaves from our pecan tree as compost? I've heard not to use walnut leaves but wasn't sure of the pecan leaves. I believe the big pecan groves here in NM use the shells as compost in the groves but there is nothing else grown in the groves but pecans.

Would appreciate advice before I toss the leaves away!

Pecan leaves are fine. So are walnut leaves.

Is the juglone found in black walnut neutralized during the composting process?

My experience is that the Black Walnut leaves and nuts do not contain enough Juglone to be of any concern. I have used just Black Walnut leaves as a mulch and found no growth suppressing qualities apparent, except the "weeds" I covered up, or quack grass growing in places I put down heavy layers of Shredded Black Walnut leaves. I have seen thios property at work where the trees roots run, but not where I have used the leaves, nut hulls, or branches trimmed off the trees.

It was asked:

Composting breaks it down, thus it is inactivated.

All the leaves and nuts as well as the shells will break down, as already indicated, it is the bacteria and little bugs, let alone the heat generated that breaks anything organic, into what we know as a quality soil with the nutrients and goodness enjoyed for healthier plants

Yes, they will be fine to use for compost. Just let them decompose as normal. You can also use pecan shells and hulls for composting and mulch.

Are the flowers of the pecan tree suitable for composting?

Yes, I know persons who used pecan waste,mostly shells & bits of nut meat as compost & mulch in their garden.
The garden was like walking on a sponge.
Black wall nuts outer shell should never be put near Tomatoes,peppers, egg plants & roses because the black spot live on them.
Sorry no link.But as the above posts state correctly, after composting the juglone & black spot neutralized.
