I've also had no issues with the passion fruit dropping event trowels.
So far I'm pretty lucky, I'm getting decent drops. The chocolatier is Def a challenge, but I do get drops. The dirt is the worst, but Judy's advice has been sound for me. I've been making wheat on about 35 or 37 plots, posting 10,discarding,trying all over again. I get 0 sometimes, but I also get 3 sometimes. Average is 1 or 2,and it goes quickly if u do it that way cuz it's so quick to grow. And there's zero risk in discarding it cuz its the foundational crop and coats zero to make. Literally. So whether u sell it dirt cheap (see what I did there?) or just dump it, it's a win, as ur end goal here is the dirt.
I got thru 4, 5, and 6 really quick. Crossing my fingers for 7.
