Are you hankering for the taste of homegrown tomatoes, but lack the real estate for a garden plot?
Well there’s no need for despair. You can have your own tasty crop without the back forty, because technically, a garden isn’t even necessary!
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.
Also, if you plan on collecting seeds from heirloom cultivars, keep them at least 10 feet away from other varieties to prevent inadvertent cross pollination.
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 supports 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.
coconut coir, peat moss, perlite, or vermiculite
And for convenience, you can always pick up pre-mixed soil at your local garden center and online.
Like this bag of organic container mix from Miracle-Gro, 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.
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 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 one 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 Alaska fish emulsion 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 burnt 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.
