Has anyone worked on a “blue oak”?
I just started on a few this year. I'm experimenting with reducing the substantial tap root. One just cut where I want it, one girdled with wire, one left along. All three have budded out well this spring, but the one with the cut tap root took much longer. All are looking good now.

Are they all this year's seedlings from acorn?

I have had a real heck of a time with repotting my seedlings, from 0 to 5 years old. They usually die when I repot, especially if I mess with the roots at all. Because of that, I'm not doing much with my oaks.

My seedlings seem to do best when I cut the tap root early while the acorn can still feed the sapling.

No, these were probably 4-5 yrs in a nursery can before I got them.

I think part of my problem is doing this in spring rather than winter. Our winters are very, very mild and the coast live oaks I have start growing in January. This next winter, I will probably try to repot in December to see what happens.

It's not you. I have similar 50/50 chances when repotting/chopping the tap root on young oaks. They just don't like it. I'm going to try treating oaks with AgriPhos whenever I work the roots to help fight rot. I don't know if that's the reason they die (it's probably a combination of shocks), but I've heard they benefit from a yearly dose regardless to stave off fungal issues.

So you do it within the first 2 months? The acorns seem to be shriveled by then.

Yes, I had good luck with mine starting them in a tray with individual 1 inch sections, once they develop decent roots I washed them (vermiculite worked well for me and washes out easy) and cut the tap root back before it has a chance to get too big, then I pot them up. Otherwise I find that the tap root has a chance to get too big. I prefer to wait till the roots start to divide.
 
This is my Quercus Robur, which I unearthed last april. It has appearantly been sitting in a black sandy soil garden for about 25 years.
Surprisingly it had only a few very thin feathery roots and I was concerned if it would survive, but now the buds are all showing leafs and I'm hoping for the best.

Appears to be but its likely some Red Oak / Pin Oak hybrid... both trees are plentiful in the area. Leaves look more like Pin Oak so... sure!

My young pin oaks tend to have leaves like that, and then they take on the classic form as they mature. I suspect there's probably a juvenile leaf shape and an adult leaf shape, sort of like junipers.

Very possible
 
I love oaks, and this one is a Quercus pyrenaica. Of the native oaks we have here, this one is my favourite. Love the velvety leaves, the colourful new growth and the paler and deeply lobed leaves.
I planted a lot of acorns last autumn, but they were of Quercus orocantabrica (it was Quercus robur, but was recently separated into its own species).
This year I want to see if I can collect acorns of this species instead.
Would like to eventually try to collect a larger one. There's lots of cork oaks for sale, but never saw one of these.

That is some nice color. Thanks for sharing the photos of your oak.
 
I agree that the probable identity of your tree imaged is Quercus laurifolia.

I have a tendency to focus on details. Not always important details. One of my "bug-a-boos" is plant names and taxonomy. Getting names "right" is a thing I focus in on, but in bonsai is not all that important. In judging orchids, it is critical that species are identified correctly and hybrids have accurate parentages listed. I have in the past exhibited orchids, and made "the deep dive" into orchid taxonomy for a while. Then I got a life. (LOL) In bonsai the image created is most important and accuracy of botanical names is a secondary or minor issue. So with this thought in mind I offer the following with the suggestion that where possible, include the botanical name of the species you are referring to when you use common names. Citing the botanical name only needs to be done once in a discussion, if there is no ambiguity, I know I sound pompous if I repeatedly use botanical names when everyone else in the thread is using common names.

Laurel Oak - 2 different species share Laurel Oak as a common name, Quercus laurifolia and Quercus hemisphaerica also known as Darlington oak

Quercus laurifolia "Laural oak" is in the same botanical section (Lobata) as red oak, Quercus rubra. Common names for Laurel Oak include swamp laurel oak, diamond leaf oak, water oak, and obtusa oak, Laurel oak, swamp laurel oak, and diamond leaf oak are probably the most used common names. This oak tends to grow on flood plains, areas that experience seasonal flooding or occasional flooding. If found in upland sites they tend to be in areas with poor drainage. They flower late winter or early spring, before or as new leaves begin to emerge. Quercus laurifolia is tardily deciduous, with foliage dropping over the course of the winter. Foliage is replaced every year. Leaves are rhombic in shape and taper to the leaf petiole, stem that attaches to the branch. Leaves are wider than Q. hemisphaerica, and are occasionally 3 lobed. It is hardy as far north as Cincinnati, Ohio, as there are specimens there that have survived more than 50 years. The article in Wikipedia did not note whether the Cincinnati trees were planted as ornamentals or represent northern outliers of their natural distribution. My guess is they were planted as ornamentals.

Quercus hemisphaerica - Darlington oak, also called Laurel oak, sand laurel oak, and laurel leaf oak - this species is also in the same botanical section (Lobata) as red oak, Quercus rubra. Quercus hemisphaerica tends to grow in more upland sites in sand. Much drier sites than Q. laurifolia, Q. hemisphaerica tends to flower about two weeks later than Q. laurifolia. Leaves are narrow ovate, more narrow than Q. laurifolia. Leaves are occasionally coarsely toothed, though most leaves have smooth margins. They are not usually lobed. Leaves tend to be evergreen.

Water Oak - Quercus nigra - has many common names including spotted oak, duck oak, punk oak, orange oak and possum oak. Oddly, the botanical name Q. nigra, "nigra" means black, yet black oak is not listed as a common name for Quercus nigra. The common name "black oak" most often refers to Quercus velutina. Leaves are spatula shaped with a broad distal end tapering, wedge shaped to the leaf petiole. It is tardily deciduous. Preferred habitat is similar to that for weeping willows, streambanks and edges of ponds, sometimes swampy waterlogged soils, or areas prone to flooding. It will tolerate compacted soils, and has been found growing in red clay soils. It is not normally planted as an ornamental. Its wood resembles red oak, Q. rubra, and is often sold as red oak lumber. Water oak, Q. nigra is in the Lobata section of genus Quercus meaning it is in the red oak section.

Chapman Oak - Quercus chapmanii in same botanical section as Quercus alba, the white oaks. Its natural range is more restricted than the above species, it occurs mainly in Florida with some outliers in adjacent states. Wikipedia does not say much about this species and photos of leaves are not close up enough to help with identification.

So this sums up most of what Wikipedia has to offer about Laurel and Water Oaks.

I find Wikipedia is very useful tool for botanical questions, if you already know "a little" about the plant in question. It is terrible as a "primary identification guide" because information is not of equal depth between species.
Water Oak, Quercus Nigra growing on my front yard has blackish acorns, maybe that's why nigra is in it's Latin name.
