Which Pepper Varieties Do Best In Pots?

Compared to tomatoes and eggplants, pepper plants are a relatively compact nightshade. But some types tend to grow better in the restricted space provided by containers than others.

Here are a few pepper varieties to consider when constructing your container garden.

  • Bell Peppers – These sweet favorites are not as easy to grow in pots as some of their smaller pepper cousins, but it can be done. Look for varieties of red, orange, yellow, or purple that mature quickly and maintain a more compact form as they grow.
  • Bulgarian Carrot Peppers – Don’t let the name fool you, these slender, orange peppers aren’t sweet like their namesake. In fact, they are pretty dang hot–almost three times hotter than the average jalapeno. They grow on bushy plants that produce dozens of fruit, making them a great option for containers.
  • Bolivian Rainbow Peppers – Often grown as an ornamental plant due to their sheer beauty, these peppers are perfect for the container garden or for the front porch. This large plant produces a rainbow of hot peppers including yellow, orange, red, and purple.
  • Fushimi Sweet Peppers – These thin, sweet peppers have a crunchier texture than the similar shishito and are delicious even when raw. They are also one of the easiest peppers to grow in pots and produce beautiful fruit all summer long.
  • Jalapeno Peppers – This popular hot pepper comes in many sub-varieties that do very well in pots. Look for types with a short growing season or shorter stature when picking a plant to include in your container garden.
  • Poblano Peppers – Deep green and extra-large, these beautiful mild peppers are the preferred type for making chili Relleno. Despite their size, this variety is known to do quite well in large container pots.
  • Shishito Peppers – These long green peppers are sweet with just a hint of spice. They are common in East Asian cooking and make a delicious snack when sauteed with oil and spices. They are one of the easiest peppers to grow in general and do very well when grown in pots.

9 Tips for Growing Peppers In Pots

Once you have chosen your pepper varieties, it’s time to start planning and planting! Here are nine tips to assure your pepper container garden is a success.

1. Pick a Hot Location

When picking a location for your pepper container garden, the most important aspect to consider is sunlight. All peppers need at least six hours of direct sunlight each day. But more is better.

Like all nightshades, peppers love the heat. They thrive in daytime temps between 70 and 80 degrees. At night, they don’t like to get much cooler. 

Putting your pots against a south-facing wall that gets a lot of sun will guarantee plenty of heat and light.

2. Find the Right Pot

Some of the more compact pepper varieties will do fine in pots as narrow as 8 inches. But larger plants will do best in containers at least a foot in diameter. In either case, make sure your pot is at least 10 inches deep to allow for adequate root growth.

Five-gallon buckets are the perfect size for most peppers. If you plan to plant more than one pepper in each pot–something that is possible with non-bushy varieties of bell peppers and others–pick a pot with a diameter wider than a foot.

Whatever pot you choose, make sure it has plenty of drainage holes. Peppers like moist soil but do not do well in waterlogged pots. If needed, take a drill with a large bit to the bottom of your plastic or metal container to add extra drainage holes.

3. Pick Good Potting Soil

The soil inside pots is subject to a much different environment than the soil in a garden bed. There are no earthworms or other bugs available to aerate it. And it is much more likely to dry out since it has a more limited volume and cannot pull water from lower depths.

For this reason, regular garden soil or dirt pulled from the ground will not work well for growing veggies in pots.

Instead, you need to purchase special potting soil that is made for the environment inside a container. This soil drains quickly while trapping moisture evenly from top to bottom. It is also less prone to compaction than other types so roots can breathe easily.

One of our favorite products is this organic potting mix from Espoma.

4. Select the Right Pepper Variety

In the section above, we looked at many pepper varieties that do well in containers. This list is a great place to start for those less familiar with container gardening. However, it is possible to grow most types of peppers in containers.

For varieties not mentioned above and those not directly advertised for container planting, make sure you use an extra-large pot. This will assure the plant’s roots have enough room to grow and will better emulate their natural growing environment.

5. Sow Early or Buy Seedlings

Most pepper varieties take some time to mature, and all prefer to produce during the hottest months of the year. This means that your window for growing peppers is fairly limited in most climates.

Direct sowing pepper seeds into your pots is generally only possible if you can bring your pots inside until the plants are large enough and the weather has warmed up. You also have the option to sprout your seeds on a sunny window sill or in a greenhouse and then transplant them into the pots once they are ready.

Buying seedlings and planting them in your containers after the weather has already warmed up is an easier route to take. But, keep in mind, you won’t be able to find the same variety of pepper plant seedlings as you can with pepper seeds. 

6. Fertilize Twice a Month and Water Daily

Once the temperature warms up to the hot temps peppers like, you will most likely need to water your pots every day. Check the soil by sticking your finger into it. If the top inch or so is dry, then give the pot a healthy drink.

It is best to water in the morning before it is hot enough for rapid evaporation to occur. This will also guarantee your peppers don’t sit in soggy soil overnight.

Because peppers produce fruit at such a fast rate, they require frequent fertilization. This is especially true of peppers in pots because a lot of the nutrients are washed away with each watering. By applying a balanced veggie fertilizer every two weeks, you’ll assure your peppers get everything they need to keep producing.

7. Keep an Eye Out for Top-Heavy Growth

Peppers don’t require any trimming or special maintenance, but you do need to watch out for the plants becoming too top-heavy. This is most common in bell peppers and other large pepper varieties.

As the plant produces more and more fruit, the stem may start to bend. If this happens, use a stick or bamboo pole to prop the plant up. Just be sure not to tie the plant too tightly.

8. Harvest When Ripe

Most pepper varieties can be harvested when the pepper first turns green or when it has matured into a more vibrant color.

For many spicy peppers, the less mature green fruit is not as hot as the more mature red or orange. Likewise, mild and sweet peppers tend to have more flavor after they have turned yellow, red, or purple. What color transitions your particular pepper goes through will depend on the variety.

9. Continue to Harvest All Summer Long

Most pepper types will produce as long as the weather is warm. By picking fruit early and often, you can encourage better production, especially early in the season. 

If the weather gets too hot, the plant may drop its flower buds and production will decrease. But existing fruit should continue to ripen (and hot peppers will be much hotter!). To avoid this drop in pepper production, you should move your pots to a slightly cooler location during the hottest period of the summer.

If you have a sunny, south-facing window, you can bring your pepper plants inside once the weather cools to extend the season. Any plants left outside after a frost will die.

Common Problems You Might Face

In general, growing plants in pots means you don’t have to deal with as many pest problems as you do in a traditional garden. However, there are still a few problems to watch out for when growing peppers in containers.

  • Pests –  Aphids, corn borers, and whiteflies can sometimes cause issues for pepper plants. If you notice any bugs going after your pots, try moving them away from other plants and areas of open soil. Washing the leaves with warm soapy water can also help remove many types of foliage destroying bugs.
  • Bacterial Leaf Spot – This is a common issue in pepper plants that causes round yellowish-black spots on the foliage. Using fresh soil each growing season and placing your pots away from other plants will help avoid this problem. If you do see a leaf with black spotting, cut it off and dispose of it right away to slow the spread.
  • Blossom End Rot – This condition causes the blossom end of the pepper to turn mushy and brown before the fruit has matured. Blossom end rot is caused by an inadequate uptake of calcium. Frequent fertilization and, more importantly, a consistent watering schedule should prevent this issue in potted peppers.
