There are rootstocks that will take either peach or apricot
scionwood. So if you grafted a peach on a Krymsk 1 or Pumiselect and
grafted an apricot on Krymsk 1 or Pumiselect will the peach go into decline and
the apricot flourish. Or is the rootstock the one that has the
problem? Krymsk 1 and Pumiselect are both compatilble with peach and
apricot.

Subject: [NAFEX] black walnuts, peaches
and apricots
I have a site I manage with shallow soil and two huge northern pecans
right next to where I've planted peach trees. The trees took off at
first as I cut back all competing roots some distance, but after a few years
they went into decline. Now I trench around the trees, double
digging with the longest bladed "King of Spades" spade annually, and the trees
are doing reasonably well. The black roots with that distinctive
juglianos smell permeate the soil.
Before I decided the issue was alleopathy I replaced a young dead peach
tree with an apricot and it did so well I planted 2 more and seven years since
planting the first all goes well with the three with no trenching.
Is anyone out there aware of evidence that peach trees are immune to this
soil toxin because this is not the only site I've seen an apparent problem
growing peaches in proximity to black walnuts or related species. On the
site with the northern pecans I seem to have a problem with raspberries but
not blackberries.
