Accessing Tree parameters in C#

This is a bit of a newbie question, though I looked around the documentation and various forums and could not find an answer to this. How can you manipulate the parameters of a Tree object in C#? Say I wanted to adjust “Tree Seed” so it increments by 1 on Update().

I can’t quite say something like:

 GetComponent<Tree>().TreeSeed += 1;

How can I access these parameters?

@leftoversalad Did you find out how to achieve it? I would need this in a similar way too.
