    Typically, you should treat a plant in a pot as though it is one zone lower than the one you live in. Many dogwoods are hardy to zone 3 or 4, depending on the variety. As for watering, most trees, like dogwoods, are dormant during cold winters so they will need less water. Don't leave them dry for weeks at a time, but do not let them sit in wet soil, or the roots will rot.

    Based on the comment that they have healthy foliage, I suspect that they have too much nitrogen in the soil. This happens if they are planted too close to a lawn that is fertilized regularly. Have the soil tested and increase the amount of phosphorous the trees are getting.

    Red Twig dogwoods should be fine in zones 7 and 8. It does sound like it died from transplant shock. Newly planted trees should be given extra water for at least 6 months, if you plant them in the spring (which is the best time to plants them. This helps to encourage them to grow new roots and establish well in the new spot. These articles will help for the future:

    The tree's branch likely broke after the tree came out of dormancy, and when this happens, the tree will "bleed" quite a bit. The bugs and mold are most likely attracted to the sugars in the sap. If possible, try to wash off the bled sap, but don't scrub too hard. Treat the area with a fungicide to keep away harmful fungus, but leave the wound to heal in the open air.

    Might be flux, try spraying with a 50/50 mix of white vinegar and water. You'll probably need to spray it twice a day for about three days. If that doesn't clear it up in a few days, try treating with a systemic fungicide. I like the ferti-lome brand, but it doesn't really matter, just make sure it's listed for dogwoods. Make sure the tree isn't being overwatered. If you haven't already remove any broken limbs, cover the cut with pruning paint if you wish.
