The Best Containers and Pots for Growing Vegetables (2026)
No yard or poor soil does not have to stop you. A pot on a patio or balcony lets anyone grow real food. The catch is size. A too-small pot dries out by noon and starves the plant, so you get a few sad leaves and no harvest. This guide gives you the right size and type for each crop.

How we picked
Size and depth matter most. A 5 gallon pot is the floor for a tomato, and 10 gallons is better. Roots need room to spread, and more soil holds more water so the plant does not wilt every hot afternoon.
Drainage holes are a must, or the roots sit in water and rot. We also picked for honesty about watering: containers dry out fast and may need water every day in summer heat, so pick a type that fits how often you can show up.
Our picks
- Best all-around for most crops
Fabric Grow Bags
Best value
- Cheap, fold flat to store, and air-prune the roots for a healthier plant.
- A 5 to 10 gallon bag fits one tomato or pepper with room to grow.
- Downside: they dry out fast and may need water every day in summer heat.
- Best for steady moisture
Self-Watering Planter
Best for busy gardeners
- A built-in reservoir waters from below, so you can skip a day or two between fills.
- Steady moisture means fewer cracked tomatoes and less wilting in heat.
- Downside: it costs more, and the reservoir can breed mosquitoes if you leave it open.
- Best for tomatoes and roots
Large Plastic Pots
Best for big plants
- A 15 to 20 gallon pot holds enough soil for a full-size tomato and is still light enough to move.
- Deep enough for carrots, potatoes, and other roots that need room down.
- Downside: cheap thin pots get brittle and crack in the sun after a year or two.

Questions, answered straight
At least 5 gallons for one plant, and 10 gallons is better. More soil holds more water, so the plant does not wilt every hot afternoon and you get a bigger harvest.
Lettuce, spinach, herbs, peppers, bush beans, and radishes do great in small pots. Tomatoes, eggplant, and root crops like carrots and potatoes need a big pot of 10 gallons or more.
Often. Pots dry out far faster than the ground, and in summer heat that can mean watering every day. Stick a finger 2 inches down. If it is dry, water until it runs out the bottom.
Yes, always. Without holes the roots sit in water and rot, and the plant dies. If a pot has no holes, drill a few in the bottom before you fill it.
