The leaves turn yellow and drop off mostly in the middle of the branch, while leaves at end of branch and the base tend to stay green. I do not see any signs of insects or mold, etc. We had an unusually wet summer in OK and then the rain stopped, and it returned to hot. Also, my tree is about 100 ft from my septic tanks (they are fiber glass). Do you think the root system will interfere with my system?
This could be the effect of the heavy rainfall. Yellowing leaves is generally an indication of a watering issue. To much or to little.
Golden Willow trees are fast growing and unlike some other Willow varieties are attacked by insects and disease. In the Willow cultivators it is not a long lived tree.
If the the soil isn't draining well, this will keep the moisture levels high and cause the yellowing leaves.
My research shows that this tree does have issues with it's roots invading pipes and sewer lines.
It's roots can spread 3 times the tree canopy.
Is there any winter precautions I should take? My tree has been planted approx. 3 months and has done really well through the summer, wind, rain or shine.
Since this is the tree's first year, it can likely benefit from some winter protection. Here are some methods for shielding trees from the cold and wind:

How often do you water a young willow tree in the winter?
If your Willow is a new planting, you should give it daily water for the first 2 weeks.
Then you can cut back. If the tree is completely dormant (no leaves) you can give it occasional water.
If the Willow is leafed out you will want to likely water once a week or when the soil is dry 6 to 8 inches down.
Adding 2 to 3 inches of hardwood mulch will help with moisture retention.
My weeping willow tree has come out of the ground several times in the last year, with last week being the most recent. Today my lawn caretaker cut the tree back till there are no leaves on the tree. Is the tree going to die? It has been planted in my front yard for over 9 years, and I don't really want it to die.
Not to worry, weeping willows can tolerate severe pruning much better than most other trees. Your lawn caretaker was probably trying to enhance the weeping effect of the tree. The tree will most likely grow back next year.
This type of treatment will also reduce the mature size of the tree, so let the caretaker know if you want it to be allowed to grow larger.

We have a beautiful & full globe willow which is several years old. We recently trimmed it due to some wind/weather damage & branch over crowding. We trimmed after we had a lot of rain to make sure moisture wouldn't be an issue. It has been a couple weeks & all of the sudden about 1/2 of the tree has turned brown & the leaves have died. The tree is mature, but not sure of the age. Even during our worst drought, it remained green & hardy. We live in N. Texas . Can you help us? Judi K.
Willow Trees will bleed sap if pruned while they are actively growing. Pruning during dormancy is important.
I suspect that the open wounds, during damp weather has opened your tree up to a fungus or bacterial blight.
If this is the case, you can apply fungicide to the tree.
You may want to have the tree examined by a certified Arborist.
Here are some links with more information.
