Hi! Hope you are doing well. I recently planted a green giant arborvitae (about 5 weeks ago) and am noticing that the tips of the foliage are turning brown. In some cases, the leaf/beach has died. Is there any specific reason this is happening (lack of water, too much, etc.)? Any information would be greatly appreciated. Thanks!

Hi. We hope you are doing well also.

Given the short time since being planted, this is likely what is sometimes called "transplant shock". Newly planted trees have lost a good deal of their roots when they were harvested, and the actual planting can be stressful and perhaps a bit damaging (broken branches, more root disruption)sometimes as well.

Take a look through our planting and aftercare (watering etc) information to see if there are any issues there: https://extension.umd.edu/hgic/topics/after-planting-care and just continue to monitor.

We can't tell from your photo how far the tree is from your fence, but Green Giants are true to their name and grow very large. Hopefully you planned for their eventual mature size of 40-60 feet tall and 12-18 feet wide. If not, we would re-plant it further from your fence.
