What is the Best Fertilizer For Pepper Plants?
The best fertilizer for pepper plants depends on where your plants are in the growing cycle. Once a certain size is reached, you have to make sure your plants get what they need to produce peppers.
Early on, pepper plants need more nitrogen (N). This helps them grow plentiful leaves and establish strong growth. Why is this important? Because the larger the canopy of leaves, the more energy the plant takes in from the sun. This is really important for later when the plant begins to produce pods.
Once your plants begin to flower, it’s time to move to the next phase. Pepper plants don’t need as much nitrogen at this point but they do need more phosphate and potassium so they have what they need to begin to produce pepper pods.
If the plants continue to get the same amount of nitrogen and not enough phosphate (P) and potassium (K), the leaves keep growing. The plant would appear healthy but it would have a hard time producing peppers. Getting the right nutrients to the plant at the right time is important.
Luckily, there are several ways to do this. You can choose a balanced, extended-release formula that covers your plants’ different needs throughout the growing season. Or, switch up the fertilizer depending on what your plants need for where they are in their growth.

When to Fertilize Pepper Plants?
A lot of people new to gardening may apply the right fertilizer but do it at the wrong time. This often results in over or underfeeding your plants. If they’re not getting what they need, when they need it, you won’t get the results you’re looking for.
Peppers should be planted in the spring when temperatures stay above 55 degrees F. Fertilizer with adequate nitrogen should be used when seedlings are transplanted into the ground. Wait until they reach about four or five inches to transplant them.
Mix fertilizer into the top two or three inches of soil then plant. Be careful not to over-fertilize at this point but give the plants what they need to establish strong roots, stems, and leaves. These are all necessary to support pepper growth down the line.
If you’re using a slow-release fertilizer, it may last several months and you might not need to add anything else. That said, the only way to be sure is to have your soil checked throughout the season.
How Often to Fertilize Pepper Plants?
How often you need to fertilize your plants depends on a lot of factors, including the type of soil you’re using, what type of peppers you’re growing, and the type of fertilizer you choose.
Generally speaking, it’s best to follow the directions included with your fertilizer. Extended-release fertilizers last for several months so you may not need to reapply them. There are a few options on our list, though, that need to be reapplied every few weeks or so.
The only way to know for sure that your plants are getting all the nutrients they need is to have your soil tested. This tells you what, if anything, you need to add.
Generally, if your plants are thriving and producing a lot of peppers, it’s a safe bet that what you’re doing is working. If your plant seems to be thriving but isn’t producing any peppers or if it was doing well and seems to have taken a downhill turn, it’s a good idea to test the soil, just to be on the safe side.
How to Fertilize Pepper Plants?
The type of fertilizer you choose determines how it’s applied.
Granular fertilizer is typically extended-release. Each granule has a water-permeable coating. Over time, as water penetrates the outside and blends with the nutrients inside and as the temperature of the soil changes, the fertilizer is slowly released into the soil.
Follow the directions that come with your granular fertilizer as how much you apply depends on a lot of different factors. Measure out the right amount of granules then mix then into the top few inches of the soil. Then, water normally.
Liquid fertilizers and dissolvable powders basically work the same way. You mix a predetermined amount of powder or concentrated liquid with water and apply it to your plants. These can usually be applied with a watering can or sprayer.
Generally, fertilizer should be applied to the soil at the roots, particularly synthetic fertilizer because there’s a good chance it could burn the stems or leaves.
That said, some fertilizers include instructions so you can apply them to the leaves if you prefer. In this case, the mixture is not quite as strong and can be applied using a simple spray bottle.
Note that if you choose this method, apply the fertilizer during the early morning or evening. If you put it on the leaves in the middle of the day when the sun is hot and bright, it could burn the leaves, even though it’s a weaker concentration.
Again, it’s always best to follow the package directions carefully as each brand is different. They all include detailed instructions and some even come with measuring scoops so you can be sure you’re using the right amount with every application.
Conclusion
If you’re looking for the best fertilizer for peppers, we know it can be a little overwhelming. There are a lot of great options out there to choose from and a lot to think about when picking the right one for your garden.
Remember, the big thing to keep in mind when it comes to peppers is that they have different needs when they’re sprouting versus when they’re producing pepper pods. That doesn’t mean fertilizing them has to be complicated, though. There are a lot of great fertilizers available that make it really easy.
Whether you choose a short-acting synthetic liquid or an extended-release formula made of all-natural earthworm castings, we found a lot of great products for you. For best results, follow the instructions carefully. Each brand is a little bit different.
If you’re still not getting the results you want, the best thing to do is have your soil tested. It’s the only way to know for sure what your plants need and when they need it.
