Dawn Redwood tips turning brown ?
I live in east TN. I had a Dawn Redwood when I lived in Middle TN and loved it. When we moved I searched to find another one.
We bought three that were about 4ft.
They planted all three last spring. We have a small farm that used to be a dairy and the soil is rich but will still be soggy,
I tried to put some horse manure and compost when we planted them.
They have grown fast but I just noticed the tips look kiind of droopy and turning brown. Is there any insect that would be attacking the tips?
I don't know the ph of our soil.
Could it be that the soil is to compacted and it needs airating?
Should I add some peat to the soil?
Would it be ok to spray them with neem?
Thanks,
sandy
So should I cut the tops of these trees?
They are about 6 ft now.
The spot they are planted looked like a good healthy spot but I have not had much luck with other plants.
The soil looks so black and rich like composted cow manure but when I plant something it just holds water and the soil is soggy. I tried to add some peat and lower the soil around it so that water does not run into the plants holes.
I did mulch them. We have had sink holes and there is a lagoon that was used for cow manure when this was a dairy.
We have holes pop up where tree roots use to be so I don't know what we have in the soil.
It looks so rich but gets soggy.
How much do I trim from the tops?
When do I do this?
Are there any insects that might attack my Dawn Redwoods?
All my searches say they are don't any problems with insects or fungus.
Thanks for you reply.

Dawn Redwood (Metasequoia glyptostroboides) is a deciduous tree. It loses its leaves (needles) every winter. These are VERY large trees. They will get up to 100 feet tall, with a spread of 25'. They DO NOT like soggy soil. If the soil is that wet, they will die.
They are a fast growing tree, reaching 50' in 15 years. They are one of my favorite trees. If you have other areas on your property that you can move them to that is drier, have them moved as soon as possible. Do not trim off the top of the trees. If they are trimmed, they will not retain their conical shape, which is one of the beautiful things about these trees. If the area you planted the trees in isn't large enough for very large trees, especially if they are near the house, you MUST move them or cut them down.
If you want another tree that will like the soggy soil,
Bald Cypress (Taxodium distichum), is another deciduous tree that loves wet soil. It grows in swamps, but does very well on dry land, too.
These also get very tall.

Whenever you transplant something you lose some of the roots. That is why you are always told to cut back the top of the plant. But people do not want to destroy the shape of trees with a single trunk, so they don't trim them. This usually results in the top of the tree dieing back. It grew well at first since it was healthy and had plenty of nourishment.
Next spring a new leader will rise from the upper most of the live branches. You will have a forever notch in the trunk that will gradually become less visible. Dawn redwoods always seem somewhat saggy.
