Growing tomatoes in containers is almost always an adventure. It can be incredibly rewarding or flat-out disastrous. Epic failures can happen for reasons you can’t control, like tomato blight or a summer that is too wet or cold. But if you don’t do these common mistakes when growing tomatoes in pots, you will have a much better chance of getting a bumper crop.
Growing tomatoes in containers can be extremely rewarding, producing abundant fruit in a compact space But a common question is – how many tomato plants can you fit in one pot? While it may be tempting to cram several seedlings together, this will ultimately lead to poor results. For optimal growth and productivity, it is best to limit your containers to just one tomato plant each
Stick to 1 Plant Per Pot
The general recommendation from gardening experts is to allow 1 tomato plant per container. More than this will overcrowd the pot, creating competition for water, nutrients, and sunlight.
Though tiny new seedlings may seem to fit together, tomato plants grow big and bushy as the season goes on. Plus their root systems will be vying for space and food in the limited soil volume a pot contains.
Tomato roots also need air circulation to stay healthy Overcrowded containers can lead to root rot and other problems, Spacing plants apart allows for better airflow at soil level,
So while it may seem inefficient to allot one plant per pot, it truly gives each tomato the best chance to thrive and succeed. Do not be tempted to plant 3 or 4 seedlings in a large container.
Exceptions for Small Varieties
The 1 plant per pot rule applies best to full-sized indeterminate tomato varieties that can grow over 4 feet tall.
In some cases, you may be able to plant 2 determinate/bush tomatoes or dwarf varieties in a very large container, like a 25 gallon or bigger. These smaller tomato types max out under 3 feet tall.
You could also possibly plant 2 patio or container-specific tomato plants designed to stay compact. But still, err on the side of caution and stick to 1 per pot if unsure. Crowding causes more problems than it solves.
Benefits of 1 Plant Per Container
Giving each tomato plant its own pot offers many advantages:
- Promotes larger, stronger plants
- Encourages greater yields
- Prevents disease and pests
- Allows for better care and feeding
- Simplifies staking and trellising
- Provides room for root development
- Improves air circulation
- Reduces competition for resources
One plant per pot is definitely the way to go for beginners. As you gain experience, you may experiment with pushing those limits. But when first starting out, embrace the 1 plant rule for success!
Pot Size Matters
In addition to allowing 1 plant per pot, proper container size is also crucial. Tomato plants need large pots, generally 5 gallons or bigger. Anything under 5 gallons will cramp their growth.
For full-size tomatoes, 10 gallons is an ideal pot size to provide enough room for roots and nutrients to support maximum growth. Patio and dwarf types may do well in 5 gallon pots.
Use containers with drainage holes to prevent soggy soil and aim for a high quality potting mix meant for vegetables. With ample space and nutrients, your lone tomato plant will thrive!
Tips for Managing Multiple Tomato Plants
If you end up with lots of tomato seedlings to manage from seeds or starts, here are some options beyond crowding them:
- Trade with gardening friends or donate extras to community gardens.
- Plant some in the ground if you have space and suitable growing conditions.
- Use large containers like whiskey barrels or window boxes to give them more room.
- Succession plant by replacing faded plants with fresh ones throughout the season.
- Try preserving methods like canning or freezing to deal with any excess ripe tomatoes.
Sample Container Designs
Here are some ideal potted tomato setups:
- 1 full-size indeterminate tomato plant per 10+ gallon pot
- 1 patio variety tomato plant per 5 gallon pot
- 1 dwarf tomato plant per 3-5 gallon pot
- 1 cherry tomato plant per 5 gallon pot
The exact container dimensions will vary but focus on allocating adequate space for each variety. With room to grow, your potted tomatoes will prosper!

Too Chilly
Along with lots of sunlight, tomatoes like warm temperatures. Tomatoes are not frost-tolerant. Even though planting tomatoes early might make you feel like you’re ahead of the season, they won’t do well until the weather stays warm. If you want to get ahead of the season, you can either put your tomatoes on carts and wagons and move them in and out of a closed space (like a garage) until the weather gets warmer, or you can cover them with plastic when it’s cold. If going this route, dont forget to harden off your seedlings.
Not Enough Sun
To tomatoes grow well, they need to be in full sun, which means they need direct sunlight for at least 6 to 8 hours a day, no skipping or cheating. Many people chronically overestimate how much sun an area receives. Determine actual sun exposure, either with a watch or a sunlight meter, before you position your pots. Also, during the growing season, the amount of sunlight that hits an area can change a lot, so check again about once a week to make sure nothing is blocking the sun.

Can you grow two tomato plants in one pot?
You can grow multiple tomato plants in one pot by using a pot that is at least 12″ deep and wide. This size is good enough to grow two tomato plants that won’t compete for nutrients and resources. There is enough distance for good air circulation and prevent fungal diseases. Is It Possible To Grow Multiple Tomato Plants In One Pot?
What size pot should a tomato plant grow in?
A 5-gallon bucket, easily found at hardware stores, is the perfect size for healthy tomato plant growth. Avoid black containers. Black plastic can absorb and hold a lot of heat, which can cause roots to be overly warm, leading to stunted plants. Plastic or fiberglass pots are a better choice than clay pots, because they don’t dry out as quickly.
How many tomatoes can you plant in a 5 gallon container?
