I bought dormant oil when I first bought trees to
plant in Massachusetts, in 1991. I've never used it on
my trees. I did get some out to mix a Tablespoon or
two in water, to swab on one of my blueberry bushes
last spring, to kill scab. Dormant oil is not an
"all-purpose" spray. It is useful for a few highly
specific pests: pear psylla, scab, and one or two
others. If you don't have those pests, you don't need
dormant oil. Nor will it benefit your trees, to spray
it anyway.

Dear Group,

     I was looking through "Pomona in Review, The First Year", and came
across an article by one of the founders of NAFEX, Milo Gibson.  He comments
concerning a grafting technique, "The only luck the writer has had putting
variety jujube on seedling jujube or on Cascara sagrada, a cousin of the
jujube, has been with this graft".  According to a reference source I have,
Cascara sagrada (also called bearberry, which is a name also applied to
certain Haws) is a type of Buckthorn (Rhamnus purshiana syn. Frangula
purshiana).  Does anyone know if, indeed, jujube is compatible with it as a
rootstock and, if so, any nursery that carries this plant?  The laxative
cascara, apparently comes from its seeds.
