My weeping Cherry tree is in a large pot in full sun. It is now 3 years old and this year, and for the first time has not flowered. It has gone straight to full leaves. The leaves are quite healthy and a good color. The tree has never been pruned and receives reasonably regular fertilizer.
Fruit trees quite often take a year off when young. It should flower next year.
We have a 10 yr. old Weeping Yoshino Cherry tree (never pruned). It has grown more outward than weeping downward, and is nowhere near the ground. One long branch has grown upward and outward with another branch growing downward from it. Can we prune the upward portion of the branch (4' long) completely off, just leaving the secondary branch? Should we wait until after spring bloom?
You can prune a Weeping Cherry in late fall or early spring. Make sure the tree is dormant before pruning.
You need to determine if the tree is a natural Weeping Cherry or a grafted tree. It is most likely grafted.

We have a weeping cherry in the middle of each of four boxwood beds and have had to replace them every few years. They grow well, then the bark begins to split and weep. We think it's due to borers and spray every spring but the problem continues.
This is a common tendency for Cherry Trees. It is called gummosis.
It is not a threatening problem.
If the bark is injured; this can be from weather and temperature changes or an injury to the bark since the bark is thin, it will ooze sap.
The tree can usually heal itself from this damage.
Prolonged wet conditions can be problematic.
Here are some links for you.

Can I plant a weeping cherry in an above ground plant box? I brought 2 weeping cherries and they were not taken care of in the garden center. We have had them in pots for a year now and they haven't flowered yet, but I was wondering can I plant them now, and if so, can I do it in an above ground plant box?
If these are Dwarf varieties or cultivators that stay smaller 12 to 15 feet tall, you can plant into large patio pots.

Do I need to do anything to prepare weeping cherry tree for winter?
Weeping cherry trees are winter hardy, however, even under severe winter temperatures they could still sustain injury. With this in mind, there are precautions that can be taken, which are discussed in the following links:

Planted a weeping cherry about 4 weeks ago. It started to die, as it was too wet. We dug it out and took the water out of the hole and replaced it with dry soil. Then replanted it. What should we do to save it, or will it die?
When you replanted it, was there evidence of root rot? If not, the chances of recovery are better. For information on root rot, please visit the following article: https://www.gardeningknowhow.com/plant-problems/disease/root-rot-in-garden-plants.htm
The best thing you can do to ensure your tree's survival is to care for it according to this article's guidelines: https://www.gardeningknowhow.com/ornamental/trees/weeping-cherry/weeping-cherry-growing-tips.htm
Sap leaking from the lower trunk. Never had this problem before. Just started in November. What should I do?
This can be due to a Canker disease.
You can remove or prune the diseased branches during the dormant winter period.
