Farming and 3rd tier crops

Hello,
I've been trying to get 2nd and 3rd tier crops on all types of fields, especially the special cotton types.
What I've done basically is plant wheat first, and I got the green bar to 100 on all fields.
After that I planted cabbage (since it drains for bars 3 and 4), and started raising the red bar.
Sadly though, after every planting, I lose 5 influence on the green bar (technically on the other 2 as well, but they're at 0 so nvm).
Since I keep on losing the same amount every planting, I'm not quite sure how I can get a tier 3 cotton (or any other crop for that matter).. I mean.. as far as I know, i need both bars to be at 100 or so.
Any solution any of you can offer for how to get both bars to 100 w/o draining them? or any other way to get 3rd tier crops?
Thank you
