it is a seesaw battle between the Crab Apples and the Junipers. I try to keep them separated. But you know how trees are they just have to mingle. It ook on a different appearance with the Hawthorns. The bark swelled and took on witches broom appearance

It is unlikely that that was a rust that swelled the bark or
caused the witches' broom.

Hawthorn (Crataegus) are not involved in ceder apple rust.
They ARE susceptible to quince rust (Gymnosporangium sp.)
but rusts affect leaves, not stems, and don't do witches'
brooms.

BTW, the Ortho Home Gardener's Problem Solver lists J.
chinensis 'Foemina' and 'Keteleeri' and var. sargentii as
"resistant" to cedar apple rust. J. scopularum and
varieties are "particularly susceptible" to cedar apple rust.

All I said was that "rust" wasn't the culprit. :-/

Sounds to me that you have/had some other kind of fungal (or
perhaps bacterial) infection going in the Haws.
