5 or 6 years ago a big spruce tree fell on this little cherry tree ant took half of it out. It never really recovered. It only grows about half to a third as many leaves as it should, and when it blooms in the spring time, its done in 24 hours. Last year I noticed a couple tiny spots of this red gel where some branches were broken. This year there are blobs of it on over a dozen branches, and even on the trunk, not near any wounds.
Heres a pic of the whole tree. It seems like the leaves are starting to turn on it already, in mid july
