Saturday was a beautiful day to walk. As the matter of fact this
summer has been very nice.

While walking in our yard, my sister noticed the bubbles on the leaves
of oak tree. I wonder if the tree is red oak? the leaves are wide
towards the tip. The bubles on the leaves are hard, they are about
the size of small peas. Is it some kind of problem the leaves are
having?

I have couple of pecan plants (that is what the nursery man sold us
as. I have not seen the peacans yet. the plants are about 5-6 feet
tall. And the deers are always rubbing their body against their bark
or chewing the growth on the plants so that they do not get much
further to qualify as trees). On one the trees leaves also I noticed
the same kind of hard bubble.

Does any one know what are these things on the leaves of my trees?

Thanks.

Most likely some type of leaf gall:

and

On an otherwise healthy tree, not worth worrying about.

Cheers,

You might not see pecans until those trees are at least 20-25 feet tall (about
18-20 years old.) My father planted pecan trees (papershell and Stewarts)
around our yard when they build the house (year I was born) and there were no
nuts on those trees until the fall I went to college. Not sure if it holds for
all pecan trees. My grandmother had a grove of about 50 trees and every fall,
our afternoon chores were picking up pecans and raking leaves.

Sounds like a gall (area of malformed tissue) induced by a small wasp
(cynipid), a mite, and aphid, or some such thing. Occasionally, these galls
are caused by relatively innocuous fungi...but not on oaks as far as I know.

Good luck with your tree

Pecans need a lot of zinc to produce nuts. I have pecans a lot younger
than the ones yu spea of, and they produce nuts and have been for some
time. Just make sure you fertilize them properly.

With fruit and nut trees it depends on how they were started. Trees started
from seed
will take much longer to produce fruit. Trees started from graphs will
produce many years sooner.
