I have this tree, that I planted about 4 years ago. Last year and this year there have been no flower buds and not great leaf growth either. What is needed to fix this? Is there a fix? What is wrong?
There are several reason why this is happening:
Dry soil conditions will cause this to happen. When the soil is extremely dry the leaves will curl up and drop off. it is also more prone to bugs when it is like this and can cause an issue.
The trees grow best in acidic soil where the PH value is up. You may need to get some food to feed the tree to bring up the acidic content in your soil.
Check for bugs such as aphids this can also cause your problem. There are a few things you can try. Here is a link to a good site that will help you out and let you know exactly what you need to buy to help your tree. homeguides.sfgate.com/
That is a sad looking tree but if you are inexperienced with caring for this tree I would suggest you do a lot of research before you do anything as you could easily damage or even kill this tree.
Are you saying the tree bloomed before last year but started looking like this last year and no blooms for 2 years?
From the picture I cannot tell which type of tree you have so you should read up on this before attempting any 'repair'.
If you really want to bring your tree to a better life you may need to hire someone that can prove they have professional knowledge in knowing how to care/prune this particular type of tree.
It may cost more than you would like to spend but may be worth it is you really like the tree.
You can also send several pictures (close-ups also) to your County Extension Office and ask for advice. They are familiar with this type of problem.

I have some links listed below that might help you understand how involved this can be as we know nothing about how you are watering your tree or do you use mulch correctly or when (or if) you fertilize and what type do you use or if your tree has ever been pruned and maybe even more but especially which type of tree you have.

My weeping cherry was blown over during one of our severe wind storms. It's a year old from planting. It still has some roots. I put it in a bucket of water and plan to add some cotton burr compost to beef up the very sandy soil before replanting.
