Just follow our tips on how to grow tomatoes in containers and pots to enjoy your own homegrown harvest.
Here’s what I’ll cover:
What You’ll Learn
Choose Your Location
Tomatoes are sun-loving plants and require a location where they can receive at least six hours of full sun each day.
Plants can be grouped together, but not so close that the leaves brush against each other. This helps to avoid plant-to-plant transmission of disease and pests.
Varieties to Select
It’s a good idea to decide on the types of tomato you’d like to grow before you head out to the garden center.
For size considerations, determinate varieties, with their limited growth, are always a good choice for containers.
But indeterminate ones work too, provided they have room to grow – and they’ll need ample support as well.
You can find more information on the difference between determinate and indeterminate varieties in this guide.
Next, look for your favorite features in the three main categories of paste, snacking, and slicing.
Here are a few reliable recommendations from each category to get you started.
Canning, Pastes, and Sauces
Paste tomatoes have meaty flesh, low moisture levels, few seeds, and a terrific taste.
And it’s these features that make them the go-to choice for canning, dehydrating, juice, ketchup, pastes, purees, and sauces.

Preparation for Planting
The minimum container size should be 12 inches high and 12 inches in diameter, or a five gallon capacity. This is a good size for bush, determinate, dwarf, or patio vines.
Large indeterminate vines require more space and do best in larger containers with a diameter of 18 to 24 inches and a similar height.
All pots require drainage holes to ensure water flows freely away from the roots. Problems like root rot arise when water is allowed to collect in the bottom of the container.
And because harmful pathogens and pests can overwinter in the soil, containers should be sanitized before use.
Spray or swish the interiors with a solution of chlorine bleach and water – 10 percent bleach to 90 percent water. Wipe down and allow to air dry before storing for the winter or planting in spring.
To ensure free-flowing drainage and healthy roots, add a layer of drainage material to the bottom of your pots. Materials such as coconut coir, pebbles, or broken pottery are suitable.
Use Top Quality Soil
But not just any old soil.
Garden soil is too heavy for pots. It compacts quickly, causing water to run down the interior walls and out of the drainage holes before the roots can drink it in.
Soil compaction also cuts off airflow to the roots, another key element for healthy growth.
It’s also important to remember that container soil dries out much quicker than garden beds do. In addition, tomatoes are heavy feeders that require organically-rich soil.
The ideal blend is a mix of healthy soil enriched with organic material, and amended with a moisture-retentive material. This creates a nutrient-rich base with a light, fluffy texture that absorbs water and retains moisture around the roots.
Here’s a recipe if you’re starting from scratch:
- 2 parts clean garden soil
- 1 part organic material such as aged compost or well-rotted manure
- 1 part moisture-locking material such as coconut coir, peat moss, perlite, or vermiculite
Mix the ingredients together on a tarp or in a large storage bin.
Or, for a more convenient ready-made option, you can always pick up pre-mixed soil at your local garden center or online.
I like this organic container mix from Miracle-Gro, since it’s blended with aged compost.
You can find six-quart bags at Home Depot.
Seedlings can be planted up and moved outdoors when all risk of frost has passed.
Fill vessels with container potting mix to within three to four inches from the top. This allows room to side dress with compost during the growing season or to add a layer of mulch.
Ensure the root hole is deep enough to bury the root ball plus two-thirds of the stem, and mix in a teaspoon of bone meal and a tablespoon of Epsom salt.
The bone meal aids strong root growth and Epsom salt helps with plant formation and to prevent blossom end rot.
Burying two-thirds of the stem also promotes new root growth. To accommodate the stem depth, snip or pinch off the lowest two sets of leaves when planting.
Add two to three inches of straw mulch, if desired, to help retain moisture and keep weeds down.
After planting, add supports in the form of cages, stakes, or trellises.
This can look a little disproportionate with a small seedling, but it’s best to add them at planting time to avoid damaging growing roots later on.
Collapsible cages made of galvanized steel are available at Wayfair.
If space is an issue, choose dwarf or patio varieties.
These are typically determinate and bred for compact growth, and staking is often optional. Check your seed packets or plant tags for mature sizes and support requirements.
Water Deeply and Regularly
Proper watering is a key factor to successful container-grown tomatoes.
Pots dry out from the sun and wind faster than the soil in garden beds, and consistent moisture is crucial for well-formed, healthy fruit.
Irregular or shallow watering can lead to problems like blossom end rot and cracked skins.
For the healthiest plants, encourage deep rooting by keeping the soil consistently moist, but not saturated.
When the top inch of soil is dry to the touch, give plants a slow, deep drink so that the entire root system gets water.
And in the heat of summer, you may need to do this every day for large plants.
Use a saucer beneath each pot to catch any water overflow.
This allows plants to absorb moisture back up through the roots during the day and also protects decking and patios from moisture and stains.
If you plan on growing a large crop, a drip irrigation system is an economical way to free up watering time and ensure your plants are watered regularly.
Healthy, rich soil gives your plants a nutritious foundation, but they’ll need supplemental feeding during the growing season as well.
When the flowers appear, top dress plants with a one to two-inch layer of organic compost and work in one to two tablespoons of Epsom salt at the same time.
Once fruit appears, feed every 10 to 14 days with a water soluble fertilizer such as fish emulsion, a balanced N-P-K blend (10-10-10), or a tomato and vegetable blend of 18-18-21.
Kellogg Organic Plus fish and kelp fertilizer is available at Home Depot.
Disposal and Cleanup
After your harvest is complete, remove spent plants from their pots and dispose of healthy ones in your compost pile. Any diseased plants should be burned or thrown out with the trash.
Discard the soil, rinse out the pots, then sanitize by spraying or swishing with a 1:10 solution of bleach and water.
Store them upside down over the winter.
Growing tomatoes in containers and pots is a fun and convenient way to enjoy your own harvest – even if you don’t have a garden!
Remember the key elements of full sun, consistent and deep watering, and regular feeding for strong, robust plants, and they’ll reward you with a bountiful crop of fresh, delicious fruits in no time.
