Can anyone identify and hopefully educate me on the orange stuff we found growing on a juniper outside our high altitude cabin (Lytton area), below? Thanks! Janet
Thankyou, gentlemen! Now to find the offending apple tree...this is a very remote area and I have never noticed an apple anywhere close by. Regards, Janet
Gymnosporangium species generally cause more damage to the hawthorn / apple etc host than they do to the juniper. The yellow thing you found is unsightly, but it tends not to cause serious harm. Usually it is apple growers trying to eradicate all the local junipers to protect their crop.
