I had two of these side-by-side in my back yard, both about 15
feet tall. A couple years ago one turned brown and died, and
I replaced it with a baby, which is now about 4 feet tall.

Today the little one looks great, but two branches died from
the base up on the big one. I cut those branches off, and
some new red growth appeared. Not a lot, but some. But the
plant in general looks bad. The leaves, while still green,
are drooping as though the tree hasn't been getting enough
water (which is obviously not the case).

Does this sound familiar to anyone?

Thanks.
