This is my 3rd season for my pink kousa dogwood. This year the flowers were a very pale pink, almost white. Is there anything I can do to keep it producing deep pink flowers like it had the 1st year?
Your soil pH may not be acidic enough; pink dogwoods do best when the pH is below 6.5. I recommend that you test the soil around your tree. To lower the pH you will need to add aluminum sulfate, and you will probably need to do it for a few years at least as pH adjustments happen slowly over time. To get a soil test you can contact your local extension office which you can find using the following link: https://www.gardeningknowhow.com/extension-search/
My Kousa dogwood was planted 6-8 years ago. It blooms profusely in mid-late June but, come July, the leaves start to show signs of stress -- droopy with wavy edges. The soil is sandy; could it be not getting enough water? Although we have had a couple of heavy rains, they have been a week apart or more. We do not provide additional water.
Kousa Dogwood prefer a rich loamy soil, so a sandy soil may not be holding enough moisture to endure the heat.
Kousa Dogwood also is not very drought tolerant. You will need to water your shrub unless you amend your soil.

We bought a 5 foot China Doll Kousa Dogwood last year with many white bracts. We are in zone 5B (bad winter this year) but the tree has survived. It is fully leafed but no white bracts to date - July 10th. Any ideas? Thanks.
Environmental problems such as the cold winter can effect flowering.

What is causing the end branches of our 4-yr. old 8' Kousa dogwood to die? There is a hole bored in the center of the branch when we cut the dying part. We have applied Systemic granules today. The tree looks very healthy except now seeing the end branches dying. Can we save this very special tree that just began to show blooms this past spring?
You could be dealing with Dogwood Borer.

I recently purchased a kousa dogwood, which I would like to place within 7 feet of my home. Will this be ok?
15 feet away from the house or foundation is the recommendation.

I planted 5 dogwoods about 12 years ago and now I see they are too close. I want to move one to the front of the house on the front lawn. However, we have a huge oak in the center of the lawn and a maple near the curb that has just about wrecked our lawn with its woody roots on the surface. I have two questions: 1) can I successfully transplant this kousa? (It has three separate trunks, each about 2 inches diameter, and it is about 14-16 feet high. 2) do I have to root prune it 6 months before transplanting because then I would have to wait till next year?
Yes, it is possible to move a Dogwood tree, and you are correct in that you will need to prune the roots.
Here is a link to an article that will give the correct process to ready the tree to be moved.

Had mine for several years now but it never blooms.
There can be several reasons for lack of flowering.
A Kousa Dogwood does not bloom until it is 3 to 5 years old.
If the tree has never bloomed I would review the planting information in the links below.
