The Sims 4 Fertilizer
Gardening Plant Quality and How Fertilizers Work
Fertilizing a plant in The Sims 4
The Sims 4's Gardening skill allows you to grow plants and fertilize them. Unfortunately a lot of what I'd learned had to be scrapped, as the devs at some point changed how fertilizer functions. First we'll look at plant evolution and quality then we'll move on to types of fertilizers. We're going to focus on only the best fertilizers and send you to other areas where you can get specific fertilizer strengths for both produce and fish.

How to Fertilize and Evolve
Players must be at level 3 Gardening in order to fertilize, which is done by simply click the plant and 'Fertilize'. Fertilizers can be applied about once every four Sim days. The fertilize command will be greyed out when you click the plant if it's not ready yet - check the next day. You are not notified when a plant is ready to be fertilized again, so it's good to form a schedule if you're trying to make plants perfect quality as quickly as possible.

Evolve happens instantly. Your plants will begin making higher quality produce the next day.
Plants evolve best when outdoors. There are five levels of plant evolution: Normal, Nice, Excellent, Magnificent, and Perfect. With each evolution, your produce will be worth more - much more when you consider at least 4-6 produce per harvest per day when in season. They will also serve as better fertilizers and boost the quality of meals when used as fresh ingredients in cooking recipes. When a plant is ready to evolve, it will begin to sparkle and the Evolve option will appear when you click the plant. Further progress will be blocked, so it's important to click the Evolve button as soon as possible. Evolve then fertilize, just in case excess 'experience' is wasted.
Fertilizers strength is tied to Simoleon value. More potent fertilizers will apply instant progress to the bar that appears when you hover over a plant. Because you're locked out after fertilizing it is best not to waste the opportunity to fertilize by using a junk fertilizer, such as using rotten minnows or low value flowers/herbs to fertilize. You're better off waiting until you have something better in many cases. Thanks to jjrmich for pointing out these levels and teaching me a bit in the process:
- Less than $5 - Near-Useless
- $5 to $11 - Low-Grade
- $12 to $19 - Medium Strength
- $20 to $49 - High Strength
- $50+ - Best Fertilizer
Using Plants as Fertilizer & Their Strength
How to get Growfruit: Buy Rare Seed Packets for $1,000 each at level 10 Gardening and get lucky (around 20% chance). Or cheat.
Plants are a primary go-to for fertilizing due to their extreme availability. Grow produce, use your own produce to fertilize other produce. Great! However, many produce are simply not worth using as fertilizer due to the long cooldown on the fertilize ability. The higher the quality level of the produce you have on hand, the higher the price becomes. You've got to GET high quality level produce to use them though, and fish are great for getting you there.
At level 10 Gardening, you get the ability to open rare seed packets. Growfruit, originally part of the spring challenge, can be found inside these packets about 20% of the time. They are no better than any other fertilizer as far as I can tell, they are just easy to get to $50.
Fish as Fertilizer and Their Strength
Large fish make excellent fertilizer. The bigger the better, but they also have a hidden modifier that determines the base rate.
The strength of fish as fertilizer varies wildly, based upon freshness. You can see all fish listed on the Fishing Guide. Here I am going to repeat the fish list and order them not by how common they are, as I do there, but by fertilizer strength THEN how common. So you can see common high strength then common medium strength. Now, there is a big caveat. One thing seriously messes with fish as fertilizer.
Freshness of fish matters and directly impacts its fertilizer strength. A foul salmon may not do as well as a fresh tuna of half the size, because it suffers a penalty due to a lack of freshness. What is happening in the background is, as a fish spoils, its internal value falls even if you can sell it for the same amount. Any fish over $100 Simoleons will still function as max-level fertilizer even when foul. An excellent freshness bass at $50 can do the same but if it ticks down even one freshness level it will no longer be high quality. Refrigerate your fish in the $60-90 range to keep them fresh until you get Excellent Pomegranates or something like that, which will let you retire your rod and reel.
There is no benefit to using a $3000 Sturgeon as a fertilizer over a $100 Salmon! Many rares should be sold for money instead. The fertilizer strength column is a remnant of the old fertilizer system but it just so happens most of the fish at the top of this chart will meet the $50 minimum requirement when fishing at level 7-10. Fish weight scales with level so you're able to catch heavier fish as you skill up.

Growfruit, Bee Boxes and Fungal Infusion (Hermit)
Growfruit (from the Spring Challenge) are the only plant that gets a 'high' fertilizer grade score. They are available by cheating (bb.showhiddenobjects). Another item that is extremely potent but not listed here is the special fertilizer you learn from the herbalism Skill and the hermit of Granite Falls. This requires a collectible item to craft, and isn't worth it unless you are a Scientist with access to a cloning machine.
Lastly, Beekeeping can provide an area of effect fertilizer effect to your plants that stacks with everything listed here. See the Seasons Beekeeping Guide for further details.
