Hello. Newbie here.

I received a bald cypress about a couple weeks ago from Evergreen Gardenworks. Tree looked great. First couple days I had it, I watered it and kept it in partial sun.. Since then I've been soaking it, keeping it in a sunny spot, and otherwise leaving it alone.

Today I noticed some of its leaves are taking on a yellowish color. Is this the start of chlorosis?

Thanks for your input!

Chlorosis doesn't set in overnight. In my experience, it's more typically noticeable in new growth...

This looks more like sun scald to me. Does it appear near the crown more? Or the outer branches?

The deep green in your first photo makes me think it was growing in a more shaded area...which isn't necessarily bad. My redwoods in full sun tend to be more light green/almost yellow...especially new growth.

Thanks for your reply. I've attached a photo where I've outlined the location of the affected leaves (i.e., outer branches).

Would say sunburn too. Does the left side get the sun? You can see the sunburn also above and below the red circle

Thanks for your feedback. The short answer is that area gets a good amount of sun, but it's not the spot that gets the most.

But the longer answer is...With the tree being so young, I haven't given any consideration to picking a front of the tree, and I've moved it around a lot the last few days without paying attention to which area of the tree was facing the sun. I was thinking that switching how it faced the sun would be good for evening out its growth, but it sounds like I should be more intentional about how I do this.

They can take full sun. They need to ""grow into it" though. New foliage emerging into full sun will be fine (keep them hydrated!)

If the older foliage emerged in shade or early enough that the sun wasn't very high yet...then got shipped to you and put into brighter sun right away, that could cause a bit of scalding. Depending on the age of the scalded leaves they may/may not recover...but it isn't usually anything to worry about.

The point of this post is: don't get sun shy! The tree may just need a "conditioning period" due to a sudden change in growing conditions.
