I currently have about 60 dogwood seedlings that are three to four weeks old. Should they be transplanted to outdoors this fall? If so, what procedure should be used? If not, how do I keep them over winter indoors? Your help is appreciated, especially since I've not done this procedure before! Charles Justice Bloomington, Indiana
Once the seedlings are 4 inches tall, they can be transplanted out to the garden or moved into pots.
Be careful not to damage the roots when moving the plants.
Dormant plants are more forgiving of transplant, so you can leave the seedlings in the trays until next spring. You can then transplant them before they leaf out in the spring.
My white flowering dogwood is over 19 years and always did great. But this year I haven't seen a single leaf yet. I see no signs of disease and I have Some green branches. Only thing that's changed is it gets more sunlight? What can I do to help it?
It doesn't appear to have any growth.
Check the branches; do the bend or snap off?
You can do a scratch test.

A tree can die off do to pests, disease, environmental issues or for unknown reasons.
We have a 2 year old dogwood and has been doing great but I see where a few of the leaves have turned yellow and have sort of brown spots on them. I water twice a week for it has been dry and hot. We live in Southern Indiana but I wonder what am I doing to cause this? It is planted at the NE corner of our house, gets some sun in the morning but not the hottest of the sun during the day. It sort of sits at the NE corner of our house underneath the overhang. What would cause this? Mary
This could be watering issues; too much or too little, pests, disease or nutrient issues.

at the base of my trees which have been in the ground for a couple of years. the bark both below the soil line and above the soil the bark is coming off. it is slowly traveling up the trees.we have had plenty of rain this year.I did put mulch around the base of the trees and it is against the bark. I have been told that is not good. the soil is not the greatest, it has clay in the soil. in Tennessee that is quite common.I'm afraid in time I will loose these trees. I live in east Tennessee. would appreciate your help !!
It sounds like Crown Canker of your Dogwoods and the trunk rot is likely the later stages of this disease.

I live in central Indiana and have encountered an infestation on two dwarf dogwood trees. I have attached pictures and wondered how to kill the nasty bugs. Thanks Doug Montgomery
Luckily the infection is still young. I recommend using a few things. This my method for both fungal infections, and insect infestations: First, you will want to prime the ground with dolomitic lime, then spread wettable sulfur to Kill off any infection in the soil. I Also like to spray the plant itself. Mix a few drops of one or more of these ingredients into warm water with a spoonful of coconut oil: Rosemary oil, lavender oil, neem oil, garlic oil, cinnamon extract/oil and for really bad cases, also add clove oil. Here is an article with more information on insect infestations:https://www.gardeningknowhow.com/ornamental/trees/dogwood/common-dogwood-problems.htm
How far can I prune down a dogwood tree without destroying it.I would like to go almost to the trunk, is its harmful to the tree?
Typically I would not recommend cutting off more than 10 percent of the tree at a time. If you decide to, then do this over a weeks time, so that the tree has time to recover in between cuts. There are a few things to be aware of about cutting dogwood trees, and they are explained in this article: https://www.gardeningknowhow.com/ornamental/trees/dogwood/trimming-dogwood-trees.htm
