What’s wrong with my live oak and azaleas and pecan trees?

I planted this oak(1 of 2 planted) last year in July when I was landscaping. It had leaves and quickly dropped them after being planted. The 2nd oak, same yard, has kept green leaves and dropped like a normal live oak does. The one in the picture has only had a dozen leaves or so on it at all times, some branches are dry, but when I check the main trunk and some branches it is still bright green under the bark. Are these black dots in the second picture a disease? Do I need to fertilize?

Sorry for the links, I couldn’t get them to post as a image.
Second, I was given about 10 Formosa azaleas that were dug up from a garden. I planted them in January. Half are green and producing new growth and leaves while the other half aren’t. Again, checking the large branches and base, it is green when scratched. Do I need to fertilize these?
Thirdly, I have two pecan trees (I know a lot of y’all hate them but I like them). In 2 years I haven’t seen them produce pecans. I want to get ahead of this problem and try to have them drop pecans this year. Should I fertilize?
Can I use the same fertilizer for all three if that’s the issue?

no idea on the oaks, I transplant a lot of oaks because I have them coming up all over the yard, I find it’s hit or miss. If one doesn’t take I pull it up and try another.
the azaleas probably have transplant shock, as long as the main stems are green leave them alone. On the pecans many only make every other year or every two years I don’t think there’s much you can do to change that. Mine are about every two years

just to add, how old are the pecan trees? I've heard Epsom salt along the drip line can help production, but not sure on the science/validity on that.

I’m not sure on the age, they’re prob 16-20ft tall but not very thick.
I read the epsom salt thing in a thread but thought it was a joke bc everyone was bashing the trees.

Your oak pictures are the same.
Soil test your sites. A lite fertilizer application never hurts. My guess with the oaks and azaleas is soil problems, watering issues, and transplant shock. July-August is the worst time to plant trees. Irrigate deeply and infrequently, every few days if it hasn’t rained.
Pecans take a long time to produce nuts. The tree knows if it’s a juvenile or adult, this could take 10 years. Not sure what area you’re in but your pecans may not have even put out flowers yet.
Hang in there!

The green grafting tape is starting to girdle the trunk. If the tree survives, you should address that

Magnesium sulfate is awesome. Obviously npk are you big 3 elements, calcium and magnesium probably finish out the top 5.

I've always heard transplanting any tree, shrub or grass was better in the winter as it was less stress on the plant... it may have been too stressed and may take time to recover
I'm no expert though

Absolutely true. Probably the best time is late fall. November in the deep South. Winter is next best. Then Spring, but must water a lot.
Summer is the worst time.
Just digging a hole in the summer is harder to do than any other time of the year

This. Pecan trees don't put out nuts every year too! OP, do you know what the pecan tree is? Elliot's take a avg of about 10 years before they have a few nuts. If they are native trees, they can take up to 20 years before they produce.

No, they were on the property when we bought it.
I know planting trees and bushes is best in spring but I had the oaks given to me and didn’t know if they could sit in the buckets until winter. The other oak and a cypress that I planted at the same time are fine.
Thank y’all for the help. I’m going to pick up some basic fertilizer and see if that does the trick.

As others have stated sounds like transplant shock from last year, carrying over into spring, from which they haven’t yet recovered. Because you are seeing green cadmium layer under the bark they are currently alive - that’s the good news - but it doesn’t means they are out the woods yet.
Zinc is an important micro-nutrient for pecans which is often deficient in soils, and others have emphasized the age of pecan trees.

Should I cut off the brown, dry branches of the oak?
Posted on 4/6/20 at 1:01 pm to Rossberg02
Are you saying you’ve scratched back the bark on the branches and see no green cambium layer, or least on some parts of the branches?
Certainly remove any dead branches, or parts of branches, that you verify are dead by scratching the bark back and not seeing green, only brown. If it is a part of the branch that is dead cut it back to healthy tissue right above a leaf node. Dead branches are just portal ways for diseases and insects to enter a tree.
By chance did you apply any herbicides like atrazine around any of the small oaks for lawn treatment?

No, I did not spray atrazine until a few weeks ago and I stay cleared of my trees, bushes, and gardens.

Good on herbicides - on the oaks and azaleas, just one good watering weekly in the absence of rain, many try to overcompensate when a problem arises and water too much leading to root rot. Hopefully they’ll leaf out soon.

Not sure about the oaks, but azealas need acidic soil. Try adding some aluminum sulfate to soil around the root system.
Pecan trees must put on new growth every year in order to produce pecans each year. So they need fertilizing every year. If they do not have growth, the tree will not produce any pecans until after a growth season. This is why pecan trees produce every other year.
Also pecan trees are susceptible to insects and fungus, so spraying them is essential. Talk to your local county agent for advice on over the counter products for spraying, many products are labeled restricted use and you may not be able to purchase them.

The problem with this one is you’re supposed to tie a yellow ribbon round the old oak tree, not a teal one.
