Dawn Redwood Browning in the Spring #867308

Asked May 06, 2024, 5:45 PM EDT

Just planted a dawn redwood at the end of last summer. The tree did well through the last month of summer and throughout the winter. This spring the tree began growing back normally but now most branches have stopped their growth with the leaves less than an inch in length. The leaves have began Turning brown from the tips going inward and some small ones have shriveled up and fell off completely. There are a few branches that appear to be unaffected and have grown full leaves and look to be perfectly healthy but the majority of the tree looks like what I said above.

Hello,

It sounds like your Dawn Redwood (Metasequoia glyptostroboides) is experiencing some growth issues. Here are some steps you can take to address the problem:

Watering: Ensure the tree is receiving adequate moisture. Dawn Redwoods prefer moist, deep, well-drained soils that are slightly acidic. They can tolerate wet soils but not early freezes.

Soil pH: Check the soil pH to make sure it’s not too high, as Dawn Redwoods do not thrive in high pH soils. If you need to get a soil test, go to this link:

Fertilization: Provide moderate fertilization to ensure the tree has the necessary nutrients for growth.

Pest Inspection: Although Dawn Redwoods have minimal pest problems, inspect for signs of Japanese beetles or other pests that may damage the foliage.

Pruning: Avoid excessive pruning but remove any dead or diseased branches to promote healthy growth.

Protection from Frost: Since late-season growth may be injured by early frosts, protect the tree as the cold season approaches.

If these steps do not improve the condition of your tree, I recommend consulting a local arborist or the MSU Plant & Pest Diagnostics Lab for a more detailed diagnostic assessment and advice tailored to your specific situation with regards to the condition of the tree.
