I've bought both gardening and plant lore. Testing it out, I get three carrots/beets/peas, two grapes, and anything with a seed gives 14 seeds instead of 15, which would let me plant 3 plots
Naw, it giving 14 seeds really looks like an error, considering that these new skills are supposed to represent having max in the old sliders, and you can't really do anything with 4 seeds except saving up, which is dumb as it'll be last gen q
Maybe they both would give 2.5 extra seeds and the game like a good boy always rounds down this time before the bonuses get added.
