The Ideal Container Size For Pepper Plants

What Size Pot Is Best For Pepper Plants?

While the perfect planter does not exist for all peppers, there is an ideal range of soil volume. Generally, pepper plants need between 3-5 gallons of growing medium to produce a healthy yield. However, this varies based on the type of pepper.

For smaller pepper varieties, like habanero or ghost peppers, your pots should be at least 3 gallons. For larger varieties like bell peppers and poblanos, aim for a pot with 5 gallons or more.

Keep in mind these are meant to be minimum container sizes for happy, healthy pepper plants. If you want to achieve larger harvests, grow in larger containers to allow your pepper plants to mature to their maximum size.

You can grow these varieties in smaller pots and still produce peppers. However, you will end up with smaller harvests, smaller peppers, and potentially stunted plant growth.

The Cheapest Pots

For the frugal pepper gardener, look no further than the 5-gallon bucket. These are usually between $3-4 and can work well as a pepper plant container. Just be sure to drill some holes in the bottom for adequate water drainage.

While 5 gallon buckets are not the most aesthetically pleasing to put in your yard, they are a practical and affordable option.

Note that 5-gallon buckets are not made for growing plants, and that the plastic used may not be food-grade. Use them to grow peppers at your own discretion.

These pots also come in many colors, perfect for color coding your plants, or simply making your garden more quirky and fun.

Fabric Planter Grow Bags

One unique option for gardeners are plant grow bags. They are highly effective for faster plant growth because of their breathable walls. Fabric grow bags are affordable, collapsible, and easily stored after the growing season.

While some bags are made of woven fabric, others are felt, offering better stability of temperature and a longer lasting build. One of the greatest benefits of this design is drainage. Make sure you place the planters in a spot where water can escape.

These fabric grow bags from Bootstrap Farmer are perfect for pepper plants and come in a variety of sizes and colors.

Modern Planter Pots

If you want a modern look to your outdoor garden, you may find what you’re looking for on You can also shop for attractive planters at department stores, gardening centers, Etsy, and even Goodwill!

Though these pots may be aesthetically pleasing, many of them do not come with drainage holes. For peppers, it is important not to over-water, so be sure your pot of choice has drainage before planting.

You can easily drill your own drainage holes, so this shouldn’t be a deal breaker. Or, plant in black nursery pots, and place them into a decorative planter.

For fancy, upscale planters, we recommend using a cheap nursery pot placed into your planter box, out of sight. Just check that the nursery pot will fit comfortably in your planter beforehand.

I already have some 25 gallon fabric grow bags. Would you suggest planting maybe 2 or possibly 3 plants (Ajvarski and Lesya) in the 25 gallon bags, or would you purchase individual bags (what size, 5 or 10 gallon) bags for each plant? Thanks

You can definitely use the 25 gallon pot - those annuum types can be spaced pretty close so you could try planting 4-5 plants in a 25 gallon pot - maybe 1 in the middle and surround it with more plants. Good luck!

I use 3 gallon paint buckets with 1/4" drilled holes in the bottom. Since I live in South Florida, I created chicken wire "cages" for the shorter young chili's and a 30" tomato plant trellis covered in nylon mesh netting for the more mature ones. Iguanas are chili peppers' Public Enemy #1.
