Please Help Identify Pest/Disease on Blackberry Leaves

WebChemist(10A CA)April 5, 2013

I've been searching around the web trying to find what might be affecting my new blackberry plants leaves, but nothing so I haven't been able to find anything that seems to match my problem.

The cuts seen here didn't start out discolored, they were clean and green almost like they had been just sliced with a knife or just bent and cracked. New cuts/cracks have developed since taking the plant home (bought at Home Depot) so it doesn't appear to be transportation damage... the only pest I've seen so far are snails, but I moved all my plants to the middle of my gravel bed since I read they won't cross scratchy rocks. And out of about 30 various black/blue/rasp/strawberry plants I've got going, this is the only one showing this problem

This is my first garden so I've not experienced anything like this before, if anyone knows what is happening that would be great to identify the issue so I can know how to fight it! :)

Another picture. Most of the leaves affected are closer to this one and not as bad as the first picture but it seems to be almost all of the mature lower leaves on the plant. Not sure if I should cut them all off or if that would be too much for the plant to handle

Mechanical damage. Perhaps hail?

In any event, not a disease or critter.

Definitely not hail. And new cuts have formed since I've had the plant, hasn't been moved or touched which is what made me think it was a pest but I will admit the holes are too thin to match any critter munching leaves I've come across so far...

Most of the leaves are too far apart from each other to be from cutting itself on its own thorns in the wind

wind.. high winds flap the leaves around.. and they shred themselves on their own thorns ...

when jean suggested mechanical.. most of us read that to mean.. IGNORE IT ... there is nothing to do..

and as a newbie.. do understand.. that leaves take a heck of a beating over the season.. and do not look martha stewart perfect all year long ...

the leaf is green.. and still functioning.. there is nothing for you to do.. nor worry about..

We have very young blackberry bush which is now showing signs of yellow and brown edging on the leaves. Any ideas?

Here is a link that might be useful:

Aredden, in the future, you should start your own new thread with your questions rather than hitch hiking on an older thread. Your question may get lost unless you post your own message.

Anyway, is Blackberry rust a possibility with your plant?
