Our cedars get weird parasites. Once in a while we get bagworms. This year I noticed some weird galls.
They look like brains.
I looked them up and the news is not good.
They
are the cedar-apple rust. They start in cedars, and then in the warm
spring rain, they sprout orange jelly-like 'hairs' out of each
dimple. The rust sends out spores looking for apple trees, which we
have. This might explain why we've never had good luck with apples.
Ever.
Check out this site for some other good pics of this fungus.
Now
I'm going to have to decide whether or not to cut down those cedars or
to cut down the apples [two of which aren't bearing anyway]. Feel
free to weigh in.
