Leaves turning red on Dogwood

I have a couple Cherokee Dogwoods that I planted last spring. They did pretty well last year and into this spring but lately the leaves have been turning from green to red.

Any idea what is causing this? Lack of fertilizer?

We had a long dry period this spring where I forgot to water them, could that be the culprit? Are they doomed?

Thanks!

If they are not rooted in well, a drought can cause the damage shown. Then again, the leaves on the outside of the tree seem unaffected.

Could it be anthracnose?

Especially with dogwoods, improper (or lack of) watering after planting can cause these symptoms. Did I mention dogwoods are extremely fussy when it comes to lack of moisture after planting?

Thanks all!

John - it's now a year after planting. That still count as "being extreemly fussy when it comes to lack of moisture after planting"?

Thanks!

With a dogwood, unfortunately, yes. Especially if they are getting a lot of sun. They just do not root out of their potting mix/soil ball very fast at all. I killed 3 dogwoods last year. The first (Cherokee Princess) died from the extremely wet spring and got some leaf disease (athracnacose?) and never made it to the dry part of summer. I planted it the previous fall so it had been in the ground about 7-8 months. I pulled it out of the hole after it died and new roots were not even .5" longer than when I planted it! The other two Kousa dogwoods died during the drought as I just could not get the ground soaked adequately throughout their rootzone. They were 2' bareroots I planted in the spring and I have noticed at my house at least, bareroots of all species require more thorough watering the first year and less help the second year and beyond compared with potted plants the don't need quite as much complete watering the first year but still need a little help the second generally speaking. All this to say planting technique and method, followed by how you mulched and watered it all play a large role is stress you might be currently be seeing.

I bought a closeout Cherokee Princess for $10 end of last summer and put it in shade until it went dormant in fall. I then washed all the potting mix off the roots and bareroot planted it. It doing very well so far and seems to be my best bet for success with C. florida.
