It's in a 4 foot urn. Drip system. Water occasionally with hose. Hasn't bloomed. What do I do? I love the intricate woody branches.
It would help to refresh the soil if you haven't done that in a while. Also check the roots; if they are rootbound, may need to root prune or move up a size in container. Our experts suggest using a nitrogen fertilizer. Here's a helpful article:

they don't have any blooms on them at all by this time of the year they are usually full and dropping. I cant open my pool till after this happens does the weather we have had in Cincinnati have anything to do with this? I don't want to wait much longer to open my pool.
Unfortunately, your photo did not come through. I am unable to see any new growth to determine whether it is flowering or vegetative.
If it has been cooler than normal, then this could cause the issue. It will likely take a little longer to bloom. There is a chance that it won't, but it is more likely that it is just a little late.
Here is an article for more information on the tree:

There is a locust tree growing in my backyard. It's about one foot high now but sprawling wide. It has thrived very fast. It's a wild plant, and I asked my landlord if I could replant it in the front yard (it's too close to the house right now), and she said she doesn't like them. I hate killing it but would need to plant it in a pot to keep it. Can that be done? Is there a way to keep a locust tree from growing beyond the pot? Thanks so much for your help.
I am with your landlord! Those trees will cause more problems than they are worth!
Still, you can keep it in container. It may not flourish, since even seasoned gardeners can have troubles with wild trees in container, but it can be done. Be sure that you do not do any transplanting until Autumn, or best, wait until dormancy.

small robinia, 5 years old, has been perfect health until I cut back a few overly long branches in early spring, leaveflets on new shoots have turned brown and crisp at the ends while the resto of the small tree looks fit and healthy. I've had very long hot spring and summer days and may not have watered as I should, Its on clay soil in full sun. Hoping its not the frisia die back Any suggestions please.
It sounds like it has contracted an infection. Likely, this happened from non-sterile pruning sheers. You can try and treat with a fungicide.
