another quick juglone question
I found a source for shredded leaves from a township that collects leaves from it's residents. They offer them back to the same residents, but there is a mountain of them from years past, so they are quite willing for "out of towners" to take some off their hands at no cost. The leaves are only collected from people who pile them on their lawn edges (not street gutters) so I am hoping that their isn't too much oil and car residue in them. Plus that fact that I won't have to pay for shredded bark mulch anymore is nice too. I live in a newer subdivision aptly named Weathered OaksÃ¢ÂÂ¦ Which is probably is the first thing they cut down when they made the subdivisionÃ¢ÂÂ¦ so the leaves from the young trees pretty much just blow away in the fall.
My question is in regards to the walnut leaves. I have found a good amount of walnuts throughout the leaves, so I then assume there are leaves too. The compost I picked up is fairly well composted and mostly leave mold. From prior postsÃ¢ÂÂ¦ I am not too worried on the juglone from this batch. It will be mostly dirt by the spring at the rate it is already composted.
I am planning on going back soon to get freshly shredded leaves from this fall to use for next years mulch. In regards to the juglone in those leaves, since I only plan to use them on my perennial beds (not veggie), does juglone only inhibit seed germination or does it actually impair growth on live plants?
On an aside note, I applied about 3-4 inches of the leaves 4 weeks backÃ¢ÂÂ¦ and yesterday I planted down some bulbs. Pulling aside the composted leaves, I was shocked to see how many worms there were. So it's good to see the benefits of using leaves vs shredded bark mulch has already kicked in.
