Help me save my giant sequoia seedling

[bradolson]

Two years ago I started two giant sequoia trees from seeds. This summer I baked it, soaked it, or it has a disease because it started dying. One is a healthy as can be (8 inches tall and full in a 6 inch pot) and the bottom branches on the other one are drying up. Please help.

What ever the one has keep the healthy one away from it until you can diagnose the problem.

We don't have sequoias in Virginia.
