Is anyone else still monitoring this thread? I see it's a couple of years old, but I found it while doing a google search for information, and it was the only thing I found that mentioned my issue of red leaves on my live oak.
I bought and planted a small, young Escarpment Live Oak last year from a local nursery, or maybe it was two years ago. Anyway, right now I am concerned. I have another live oak in the back yard. Not sure if it's the same species or not, though the leaves look the same. This other one has little catkins on it, and healthy looking new green leaves.
However, the Escarpment Live Oak, while it has definite new growth, has a lot of leaves that have turned red, and the new leaves are also red. Some of the leaves are also more of a brownish, red on the end of the leaves, gradually turning brown toward the stem. However, they are glossy and pliable, not dull or dry. They look alive, just red. Also, all the new leaves on the ends of the branches are coming in red.
The red/brown ones do not look like the pictures I've seen of oak wilt. Nothing along the veins. There are a handful of yellow leaves mixed in that just look like normal leaves that die and fall off. Oh - I'm in the southeast Austin area, out near the airport.
What is this? Did anyone figure out whether it's normal or a problem? I am no gardener, just a suburban homeowner who wants a few trees. Please help, anybody?
