My Aspen trees lose their leaves early, turn brown early. The bark isn't as White as they normally are, they're more Grey now. What can I give them a Boost of? It's early season and the branches have no buds for the leaves yet. Thanks for any help or suggestions
Unfortunately, your photos did not come through. Here are a couple of articles that will give you information on the needs of Aspen trees:

I recently had several blue spruce trees cut down on my property. I am having the stump grindings left behind and want to know if mixing the stump grindings with topsoil will be beneficial or harmful to the Aspens.
You will want to check the pH first. Many times, Spruce will change the pH of the soil to be too acidic to support the growth of other trees.
If the pH is within an acceptable range, then you can plant safely. If the pH is not in an acceptable range, then you will want to amend the soil.
It will be good to amend the area with compost prior to planting, anyway.

This aspen tree is dead on the top. Can I cut off the dead stuff or will it kill the tree?
Pruning off the dead portion won't kill the tree, but you will need to figure out what did. If it isn't corrected, then the problem will likely happen again. Copper fungicides can manage serious diseases, but there are many tree diseases that are fatal to them.
This article will help you to treat the tree:
