Q.Can young dogwood tree survive outside during winter?
Can a very young dogwood tree survive outside during winter? I have a very young dogwood tree that was planted in a pot this past spring/summer. It is about 1 foot tall, so it is still very small. I have it on my deck in a pot and it has grown leaves. Should I keep it outside during the winter or bring it indoors?
Dogwood Trees are Hardy in zone 5 - 9.
That said your young tree is very small. It may not have the root system to withstand the winter.
I would allow it to go dormant and store for the winter in a garage or similar location. You can add some protection around the pot. Check the plant once a month to make sure the soil has not dried out completely. You can add a small amount of water if the soil dries too much.
You can then plant your tree out in the spring.
