@crinrict I assume you are talking about the subject of the current thread compared to the subject of the 2018
https://answers.ea.com/t5/Bug-Reports/OPEN-Fertilize-several-plants-with-the-same-item-doesn-t-work/td-p/6932848 which you recently edited.
Most all of my plants have been 'perfect' since before 'Seasons', therefore the complaint in the 2018 report about the plants not getting a quality "boost" after fertilizing would not have affected my game.
I did notice however, that my fertilizing inventory was not being consumed by the number of fertilizations I was exercising, e.g. if I fertilized 8* plants with garlic, only 2* garlics disappeared from my inventory. (*I can not say exactly how many, the numbers I mentioned are a guess) In my case, all the plants I fertilized truly were fertilized and they were shown to be fertilized. They produced their harvestables daily as usual. I usually collect the harvestables daily and fertilize every 4 days. I can not say how long ago I observed the lack of proper depletion of harvestables in my inventory while fertilizing, but it has been at least a few months. I didn't mind it, because it was a plus for my sims.
I do not play with any mods, but I do have over the recommended amount of sims in 'My Households'.
Currently, I do have the same problem that
@DanishLighthouse reported.
I hope I have helped.
