10. Trash Fruit

Trash Fruit, while not the best fertiliser available, can be extremely beneficial in your game. They spawn when trash is left on the ground and are extremely easy to obtain. The plant yields quickly, but the fruits are completely useless! 

This is what makes Trash Fruit such an excellent fertiliser. Because the Fruit only sells for one, it is useless to your sim. You could use the harvest to grow some high-quality plants, albeit at a slower rate than some of the others on this list.

Why Trash Fruit Is Great:

  • Really easy to obtain
  • The plant produces Trash Fruit nearly every day, so you can harvest high numbers of it
  • useless other than using as fertilizer, so it’s a good way to make use of trash

Trash Fruit details:

  • Free to obtain
  • Obtain from planting trash, or simply leaving trash on the ground.
  • Only sells for §1, so may as well be used for fertilizer
  • Relatively low-strength, but you can easily obtain it in high numbers


9. Anglerfish

The rare Anglerfish is an intriguing fertiliser option, but when used correctly, it can work exceptionally well. It is a medium strength fertiliser, but when applied fresh, it can cause a significant improvement in plant quality. 

It's not the easiest fish to catch due to its scarcity. Anglerfish can be found in Forgotten Grotto and Sylvan Glade Ponds, and using Bass, Salmon, or Catfish as bait will increase your chances of catching one!

Why Anglerfish is Great:

  • It can be a challenge to catch, but the payoff is worth it!
  • High weight
  • It’s a medium-strength fertilizer, but it works very well when it’s fresh.

Anglerfish details:

  • Free to obtain if you already have the required bait
  • Obtained by fishing in Forgotten Grotto and Sylvan Glade Ponds, using Bass, Salmon, or Catfish as Bait.
  • Select fertilize after clicking on the plant that you wish to fertilize, and then select your Anglerfish from your inventory


8. Rose

The Rose is a rare plant in The Sims 4 that blooms in the spring and fall seasons. Because of its low value (29), it is best used as a fertiliser. It only takes 48 hours to fully mature and can be found in Willow Creek behind Umbridge Manor Mansion. 

It is quite strong as a fertiliser, so give it a shot!

Why Rose is Great:

  • Free and easy to grow
  • It is low value to sell, so its best use is as a fertilizer
  • It’s a high-strength fertilizer that works very well

7. Tuna

The large tuna is an excellent example of how fish can act as excellent fertilisers. It is extremely common, easy to catch, and extremely effective as a fertiliser. You will not be wasting money if you use tuna as fertiliser because it is very cheap. 

This fish requires the City Living Expansion Pack to obtain, but it is otherwise very easy to catch! Simply go to any fishing spot in San Myshuno or any other fishing spot around the world and catch that tuna.

5. Pet Poop

The larger the better when it comes to using pet poop as fertiliser! When your sim picks up pet poop, it is added to their inventory, where it can be retrieved and used as fertiliser whenever they want. 

It is one of the best fertilisers in the game and works even better than rare fish! You'll need the Cats and Dogs expansion pack to get dog poop, but it's well worth it.

4. Bees

You can fertilise any plant within 5 squares of Burtie's Bee box, which is included in the Seasons Expansion Pack. This means that if you strategically place your bee boxes, you can cover a larger area of crops with fewer boxes. 

The best part about using bees as fertiliser is that no special interactions are required! It is sufficient to simply place the boxes as long as they are happy and healthy. 

The bee box, which costs only $265, allows sims to pollinate nearby plants with little to no effort!

  • Collect a swarm of bees from the box, go to any location, and select the interaction “Pollinate Nearby Plants” in order to fertilize all of the plants in the vicinity


3. Wolf Eel

The key factor in using fish as fertiliser is the freshness of the fish! The potency of its fertilising ability is directly proportional to its freshness, so make sure your Wolf Eel is as fresh as possible!  

Even when not at its freshest, the Wolf Eel is a large, relatively uncommon fish that is a high-strength fertiliser. It is worth around 108-364 and can be caught or gifted to your sim.  

Head to Forgotten Grotto to catch this fish (with Frog as bait), or you might get one as a random gift during Winterfest!
