What do you use to fertilize the plants?

Same. But the best, obviously, is dog poop.

Really? I didn't even know you could use that lol

I'm not sure I can do it. They look so stinky and with those flies buzzing all around. Besides, usually, some random person will walk by and step in it before I can clean it up :smirk:

The poop.

Before the gardening update that came just before Seasons came out, the best fertilizer was any large fish, with sturgeon being the best. After the update, the best was Growfruit. Since a more recent patch, now the best fertilizer is any plant or fish worth 50 simoleans. There is three levels of fertilizer actually all based on price now instead of weight.

The first level is 10 simoleans, second is 20, and the third and best is 50. If you use any plant or fish above 50 simoleans, it's a waste of simoleans because it won't be any better than the 50 simolean plant or fish.

In light of all that, I use snapdragons, roses, chrysanthemums and Bird of Paradise plants for fertilizer. I stop using the BOP though once it begins to evolve above 50 simoleons. The base level price for those is I believe around 51 or 52. If you'd like more indepth information about gardening, I suggest watching a video on YT made by Carl of Carl's Sims 4 Guide website. Here's a link:

This video is where I got the above information. Actually Carl's entire site is a must to visit for anyone new or even experienced with TS4. He provides a treasure trove of valuable information about the game. Hope this helps! :)

I use whatever fruit/veggy/fish i have in the inventory.

I always use mushrooms unless my Sim does fishing, then I use fish. I also use dog poop if possible, but mushrooms are just so easy. I always plant one mushroom and I never sell them, I harvest them for fertilizing other plants.

I use the bird of paradise that my sims get from the romance festival flowers. I plant a couple of them outdoors and then a few indoors and I usually fertilize them with themselves until they are a little bit higher than halfway. Once they hit that then I will start using them to fertilize my other plants. In no time my plants are Perfect quality and Im making some good money off them.

Bees. You can fertilize on top of using bees, but why bother?

I always use fish.

I actually grab my perfects from a dedicated farm in San Myshuno (and they get theirs by grafting onto perfect carrots). If for some reason one of my sims doesn't have access to the farm I use Growfruit, because I wasn't aware of the new 10/20/50 rule. Thank you @Karababy52 for this info!

Dog poop isn't working for me anymore since november. Might be a mod conflict if nobody else has that problem.
