Boss battles is ez with pesticide (3-4 full growth for stump field), coconut field is ez (cause Coconut Crab is ez with lv 10+ Gifted Vicious bee), and with petal wand you will collect like 3m pollen per round (means like 9 rounds for quest completition).
MITM is also ez but can be some issues with 1b red and blue pollen.
In my opinion, the hardest one is Red delicacy, cause 25m red pollen from coconut and 50 m from pumpkin is mad (but counterable will full pesticide planter)
