Q.redwoods
I have a young redwood from a cutting. It is about 8 years old and just this year looks like it is almost dead. It grew to almost 4 feet. We live in Delaware and bring it in every winter. It seems as if it may be waterlogged. Do you have any suggestions?
Water the container tree only when the soil has dried. Over watering can lead to root rot.
Lack of humidity can also be an issue for these trees.
It is recommended that these trees be planted out after 1 to 2 years of container growth.
Since your growing zone does not support year round growth of a Redwood Tree, you will need to continue to grow in a container.
The tree may have reached it's lifespan in a container and the lack of it's natural growing environment may too much stress for your tree.
Unfortunately the tree will eventually become too large for a container.
