Please offer me some advice. The dogwood tree in these photos was planted in August 2017. Since then, it has grown very little and hardly flowers at all. We feed it Plant -Tone organic fertilizer every spring and fall. I was expecting the tree would look better after nearly four years. This is my first dogwood so I don't know if my expectations are realistic or if my tree needs help. Thanks for checking this out.

It doesn't look normal to me.

Any ideas on what I can do to help it?

Well dogwoods are slow to get started every year. But I was unfamiliar with Plant Tone. It is an organic slow release fertilizer rated at 5-3-3 which is almost not fertilizing at all in my opinion.
But that's is just me. I do not subscribe to organic stuff. If I want to fertilize something, I fertilize it. I prefer using Mir Acid and Miracle grow. I don't think that Mir-Acid is around any more.
I use Jack's water soluble fertilizer for everything. My orchids, hostas, perrenials, annuals. It is 20-20-20. I fertilize once a month starting in April. I mix a concentrate in a 5 gallon pail, 3 cups and fill with water. Then I put a cup of that concentrate in my watering can, after they have been watered, and hit them with fertilizer.
My azaleas here get a dose of one cup in a 5 gallon pail every September first. That's when I want to give them a big shot to hopefully make more buds.
You should be able to physically see how many buds there are for next spring by looking at the branch tips. But if it hasn't grown much, or bloomed well in 4 years, try fertilizer. The Plant Tone is woefully inadequate.

What sort of soil do you have? Dogwoods need soil with lots of organic matter, well draining and slightly acidic. But they must also stay moist. If your soil doesn't drain well or if you aren't watering enough, your tree will have problems. I don't think the Plant-Tone is supplying the right nutrients to your tree. Organic fertilizers work on the assumption there's something in the soil that, with the addition of the organic fertilizer, will jump start the soil. Unless there is lots of organic material already in the soil, they don't work as well. Instead of fertilizing spring and fall, fertilize early spring, early summer and mid-summer. Switch to something with more nutrients and especially more nitrogen.

How long ago did you fertilize?

Thanks for the advice. I have Miracid which I use for my hydrangeas. I'll fertilize tomorrow. I was holding off applying this spring until after I posted on this site. How often should I fertilize it? Every two weeks?
I started with Plant-Tone because it was recommended by the nursery. Since it's not working, I'm happy to switch.

I feel like we are having two conversations.

Tree! Trees should only be fertilized 2 or 3 times a year, depending upon the length of your growing season (about every two months during active growth). Trees grow more slowly than other plants so can't use the amount of fertilizer we would give our houseplants (but I don't think our houseplants need it either).

The Miracid may work as it has a good dose of nitrogen in it and Dogwoods do need more nitrogen then you might think. Acid is also good as the tree can't utilize the nutrients unless the soil is slightly acidic (but you can go too far).

But two things: The roots are not just under the canopy, they have spread out in search of nutrients and moisture. Your entire garden will need to be fertilized with the Miracid. AND only 2 or 3 times this summer, not every two weeks. In your zone, probably only twice: now and again in July or early August.

You can not fertilize a tree into good health!!
Fertilizer supports good growth, it does not create good growth.
