After the snow and ice I noticed some growth on my Crape Myrtles, anyone know what this is and should I do anything about it? It appears to be just growing in the bark, ant that is starting to peel. I know it normally peels off, but I don't normally see this strange growth. Reminds me of Spanish moss in some places.

Ah, I found it.
http://www.clemson.edu/extension/hgic/pests/plant_pests/tree...
" Lichens: A lichen is an unusual organism composed of a fungus and an alga living together in the same body. Lichens often appear as green to gray-green leafy or crusty growths on the trunks or branches of plants. Typically, they occur in abundance on plants that are declining in health or vigor. They are harmless to the plant, and are in no way responsible for the poor health of the plant. Less vigorous plants tend to be more open, increasing sunlight penetration, and subsequent lichen growth."
These trees are right out in the open, away from everything else. Strange.

I love lichens and have unsuccessfully been trying to grow fallen branches with lichens in my vivarium. For one, I think the lighting is wrong. I am going to try to adjust the lighting next. I have some Spanish Mossy ones and some flat ones. I just pick up a small dead oak branch with an abundant amount of sage green lichens. It looks really cool in the vivarium. The turtle has yet to discover and destroy the branch.

Does your yard have any pecan trees? I think pecan trees in particular are usually covered with Lichen, you can see it on trees in groves along the highways. When our pecan trees drop sticks, they are always covered with Lichen, most oak sticks too.

No, but I wish I did have pecans. I have lots of Oaks though. I noticed when driving through the neighborhood the other day, that all kinds of trees seemed to have Lichen growing on them.

Yeah, not everyone is in favor of such a big tree next to their house, (or listening to pecans falling on the roof) but the giant pecan on one side and the nearly as big oak on the other side save us a lot of $ in cooling costs. The pecans are known for throwing huge limbs down for no apparent reason, I just hope we're not home when the one over the house comes down. Until then, it sure makes a lot of precious shade when it's hot.

But to say something on topic, does anyone else not like to get the lichen smell on their hands? I wouldn't mind so much but it lingers even after a shower. I don't do much with gloves, not a bit worried about getting dirty, but picking up sticks before mowing is now one thing I put gloves on for, to keep that smell off of my hands. It's a lost cause when we have a fire in our pit though, I'm one of those firebugs who keeps throwing in twigs and sticks the whole time.

I would bet the cooler, wetter summer was really conducive to lichens? I don't know much about this stuff.

Tiffany, have you tried washing your hands with white vinegar to get the smell off?
I am a strong believer in the simple fact is that what matters in this life is how we treat others. I think that's what living is all about. Not what I've done in my life but how I've treated others.
