Ok, you'll have to do a few things first. If you don't want to change every decision you've made you can load Stolen Hearts in Chapter Select.
⠀➢After completing Stolen Hearts, go and complete Operation B.O.B for unlocking the Forest.
⠀➢Go and start Plotted Weeds quest.
⠀➢Advance the quest until you're doing your little farm, choose "Ask someone else to do the hard work for you" (You'll need the Nurse's Picture)
⠀➢Enjoy
Hope this is helpful!
