cool thats nice and easy : )
The answer to achieve a faster shutter speed to freeze vegetation movement and retain your depth of field is to focus stack.
Shoot multiple images at a wider aperture then align them and stack them in post.
Or embrace the movement and go even slower with the shutter speed (smaller aperture, lower ISO or ND filter) to completely blur it.
Why not just wait for no wind?
Focus stacking does not work with moving grass and leaves.
