Hi SAW,
when you have plenty of time then go to the location you have selected for your milkyway shot (use Photopills and/or Planit Pro on your mobile to optimize this decision) early, i.e. before it gets really dark, mount your camera and make some blue hour shots with focus on the foreground and low ISO. Wait until the stars get out and then make your milkyway shots as usual. At home stack your MW shots (with Sequator or DSS) and combine the result with the blue hour foreground shot, which is optimal as the colors will fit together without much tweaking.
I made this picture that way: https://www.instagram.com/p/B5bIty9BtSU/
Hope that helps and clear skies!
