Does anyone out there know of the best source to secure some live oak tree seedlings? I would even take some semi-mature young trees.
The best thing would be to ask your local nurseries, or look around online. I have ordered many plants from many different online places from around the world, and most of the time everything turns out just fine.
Is Dusty Miller toxic to root system of CA Live Oak? DBH 18" Bed in question is 9 feet from base of tree. Shade estimate 65% Looking for a shade tolerant plant with qualities of Dusty Miller. Color not critical. Thank you for your considered suggestions. Paul Steffen Simi Valley California
I am not able to find anything in my research suggesting that these are not compatible. You will have to watch and make sure that the plant has no bad reaction to the tree. Some plants to have a hard time with the chemicals that the acorns emit into the soil, but I was unable to find anything that suggests that these two are not compatible.
I have a clump/group of 4 live oaks. One of the four, the one on the right in the photo attached, the leaves are turning brown and dropping. The leaves on the ground look spotted (see attached). I don't know if the leaf spots are ultimately to blame for them dropping...any idea what is wrong? Is the tree dying? I do know it is caterpillar season, but I'm not certain because the canopy is so high. The soil is not too dry or too wet. Honestly conditions water wise look perfect. Trunk looks healthy
Sometimes, infections can happen within the soil. Fortunately, this is usually curable. Wettable sulfur and dolomitic lime will help here. It may take a few weeks, and old growth will not recover, but newer growth will be free of symptoms.
The bark on the Live Oak Tree in the front yard has large cracks in it and we are afraid we might lose the tree. The limbs and leaves look healthy but there is something definitely wrong with the bark on the trunk of the tree.
Likely it is a result of root rot - crown rot due to the sprinkler placement and spraying of excessive water on the base of the tree trunk.
There appears to be an extreme amount of bark loss, indicating death of the underlying growing layer. There may be some bands of conductive tissue intact and that is why the tree can still get some uptake of water and nutrients. But I expect that the damage is too severe and you will lose the tree within a year.
Consult with a local certified arborist.
Our tree has been planted in the ground for at least 3 years. Prior years it seemed to grow extremely well, but this year it did not leaf out fully and seems to be unhealthy. The area where it is planted is well drained. What could be wrong with it and what should we do to promote it's continued health?
I'm a California arborist so I don't know all the possibilities for your locale, but I do know that "oak wilt" disease is the big one for Texas.

You may want to get a local arborist/PHC specialist (plant health care) to advise. There are treatment options available depending on stage if infection.
Another possibility is drought stress (water deficit) with the heat wave I've heard about in many parts of Texas.
What deciduous trees like the Live Oak keep their leaves all year long down to zone 9/10?
Marcescence is the retention of dead plant organs that normally are shed; or trees that keep their leaves in the winter!
Oak, Beech and Hornbeam all keep their leaves through winter months.
Many palms also keep a skirt of growth under their fronds.
We are laying St. Augustine sod around several of our mature oaks. To prepare the soil we would like to be able to bring the roots back down to grade.
Your trees could suffer. It is typically not recommended to cut tree roots. You might consider covering them with mulch or groundcover.
