Eigen,

Nothing can get in but the siding isn't supposed to keep things out, it's
supposed to shed rain. By caulking it you will seal in water and encourage
rot. Hate to say it but if you thought caulking was hard you'll be amazed at
how hard un-caulking is.

What he said. You're trying to combine functions, which is usually a
death sentence for one of the components of the system.

If you have grass growing inside the wall your grade level is too
high. That has to be addressed before anything else. Then you deal
with air infiltration and critter entrance. Caulking or expanding
foam between the sill plate and foundation is the typical method.
You're really just trying to slow things down as you'll never preserve
sanity if you try to eliminate all possible means of entrance. That
leaves the siding to do what it is designed to do - keep out weather
and look good - and that's a maintenance thing.
