How to Grow Tomatoes in Pots — Even Without a Garden

How to grow tomatoes in pots like a gardening pro

Tomatoes are the holy grail of gardens. Who can resist all those sweet, juicy orbs ripening in the sun every summer, filling the air with that unmistakable heady scent of tomato vine?

Hands down, it’s one of my favorite plants to grow every year and I grew it without abandon in my last garden, in the ground, when space was not an issue for these large, unwieldy plants.

But when I uprooted to a different part of the country and found myself in a rental home for the short term, with only a deck that was suitable for gardening, I thought my tomato dreams were dashed for the next couple of summers.

Not so!

That first year, I ended up growing a wide variety of tomato plants in containers, easily and successfully, in my hardiness zone 6b climate. I had enough of a harvest every week to eat fresh and cook with, and a final crop at the end of summer for several jars of homemade skin-on tomato sauce.

I found that an unexpected benefit of container plants is being able to protect them more easily from critters (in my case, growing tomatoes on a second-story deck deterred all the deer in my neighborhood), not to mention having better resistance against pests and diseases that naturally live in the garden (since you start with fresh potting soil).

Growing tomatoes in pots really levels the playing field in the home garden game, as it allows even gardeners short on space (say, a balcony or side patio) to grow beautiful and productive plants regardless of real estate.

Grow productive tomato plants in pots

So what’s the first thing you need to know?

The key to being wildly successful with growing tomatoes in pots is proper planning.

First, make sure you choose a location with at least 8 to 10 hours of sun (6 hours is the bare minimum, but more is much better).

(If your yard is shadier than you’d like, here are a few options for tomatoes that can grow in shade.)

Then, follow my tested-and-true tips below to learn how you can maximize the minimal space you have and cultivate healthy, vigorous tomato plants in your small-space container garden!

1. Choose the right type of tomato.

Determinate types (also called bush, compact, or patio plants) are usually the best tomato plants for containers, as they grow to a predetermined size — no more than 3 to 4 feet tall — and set flowers and fruits all at once, making them reliable and predictable in tight quarters.

Determinate tomato plant

However, you can still grow indeterminate tomatoes if you give them a large enough container and good support for their vines. (More on my favorite tomato supports below in Step 9.)

A good rule of thumb is to grow determinate tomatoes if you have a short growing season, got a late start in the season, or have a very limited footprint.

Recommended determinate tomato varieties: Glacier, Red Siberian, Italian Roma, Supremo Roma, Cherry Falls

If, on the other hand, you have a decent growing season and enough space for a large, tall plant, indeterminate tomatoes will give you abundant harvests all summer long and are totally doable in containers!

Recommended indeterminate tomato varieties: Cherokee Purple, Green Zebra, Black Krim, Cuore Di Bue, Chocolate Cherry

2. Start with a strong and healthy transplant.

Ideally, the tomato plants you start with should have been repotted at least once, and hardened off properly so they’re ready to live outside in the sun.

(If you started your own plants from seed, follow my previous guides on how to repot your seedlings into larger containers, and how and why to transplant them a second time.)

Repotting assists your tomato plants in developing larger root masses, which in turn helps them survive the shock of transplanting, resist pests and diseases that prey on vulnerable young plants, and grow stronger overall.

If you’re bringing transplants home from a nursery or garden center, look for thick, sturdy stems and healthy green foliage free from insect damage, sunburn, and yellowing (which indicates watering issues or nutritional deficiencies).

Start with a strong and healthy tomato transplant

I also try to avoid “top heavy” plants on tall, skinny stems, as it could be a sign they haven’t received adequate sunlight or been repotted.

3. Don’t be shy with container size, and choose a fabric pot over a plastic pot.

When it comes to tomatoes, the bigger the pot, the better.

Determinate varieties should be planted in 10-gallon containers at a minimum, while indeterminate varieties need, at the very least, 20-gallon containers to thrive.

Any smaller than these sizes and your plants may not be as productive as they could be.

My favorite type of containers are fabric pots, like these ones from Root Pouch. They come in either non-degradable or biodegradable versions, but for container gardening, I prefer the non-degradable Boxer line so I can reuse them year after year.

Root Pouch fabric pot for growing tomatoes in containers

Fabric pots are beneficial for plants with extensive root systems because they naturally “air prune” the roots.

The effects of air pruning in breathable fabric pots are best seen when compared side by side with plants contained in non-porous plastic pots.

When the roots in plastic pots grow long enough to hit the sides of the pot, they continue to grow round and round in a constricted pattern (spiraling, kinking, and twisting around themselves), eventually becoming rootbound.

Roots in fabric pots, on the other hand, are exposed to air as they grow. This exposure “burns off” the tips of the roots, which stops them from growing long and spindly. Instead, they branch off and form new, shorter, fibrous feeder roots.

Because growth is well distributed throughout the soil volume (and not just on the edges of the pot), the dense network of branched roots is able to increase the plant’s uptake of water, utilize all available nutrients, and aid in its natural defenses.

Effects of air pruning on fabric pots versus plastic pots

The permeability of fabric pots also helps to promote proper drainage of excess water and improve oxygenation to the roots (which maximizes the plant’s metabolic performance and, in turn, boosts crop yields).

In cooler climates, however, black plastic pots do serve a practical function. They hold heat in and keep roots warm in late spring to early summer, when tomato transplants are most susceptible to temperature swings.

On the flip side, black plastic pots may get too hot in the peak of summer, so they need to be shaded to prevent the rootball from overheating.

You can wrap or cover plastic pots with shade cloth, canvas, or towels to insulate against the heat (office binder clips work great for securing them), as well as try to keep them off heat-retaining surfaces like concrete.

Whichever kind of container you use, be sure to place a heavy-duty saucer (I use this one) underneath before you load it up, and have it placed exactly where you want it — it’ll be very heavy to move later on.

Not only will the saucer protect your deck or patio from standing moisture, it will allow your plant to absorb any excess water over the course of a hot day.

4. Use high-quality potting soil.

Plants in containers need a good combination of breathability, absorption, and moisture retention.

The topsoil from your garden (as well as any commercially bagged mix labeled as “raised bed soil” or “garden soil”) is generally too dense for potted plants, and it increases the risk of your tomato plant picking up a soil-borne disease that’s otherwise easily preventable.

I recommend using a high-quality premium potting soil or potting mix like this one, and try to avoid reusing potting soil from past seasons if your plants had pests or diseases. You can also make your own potting mix with only three ingredients.

Spread about 3 to 4 inches of potting soil on the bottom of your container, then continue with Step 5.

5. Feed your tomato plant well.

Tomatoes are heavy feeders and need ample nutrients to produce well and long into the season.

Before putting the tomato transplant in its final planting hole, add the following amendments to the soil and stir them around a bit:

Add a diverse mix of amendments to your tomato planting hole

Once the amendments are in, spread another 2 to 3 inches of potting soil on top.

6. Bury the stem of the tomato plant.

Gently pinch or snip off the lowest sets of leaves until you’re left with a bare stem on the bottom one-third to one-half of the stem.

Center the tomato plant in the pot and fill the remainder of the pot with more potting soil until it’s filled to the brim (just below the last set of leaves). Gently shake the pot to settle the soil and add more as needed.

Plant tomatoes deeply in the soil for better root development

Top off the soil with 1/2 cup all-purpose fertilizer (I like this one) and lightly rake it in around the base of the stem.

Feed tomato plants with good organic fertilizer
Fertilize tomato plants starting at week six

7. Water thoroughly and consistently.

Water the root zone thoroughly until the soil is evenly moist. I usually water the plant in, wait about 10 minutes, water again, wait 10 minutes again, and repeat until water runs freely out the bottom of the pot.

It takes a surprisingly large amount of water (at least a gallon, from my experience) to fully saturate the soil the first time. Don’t assume that just because the water drains right away on the first watering that the soil is soaked through.

Proper watering is the key to success when it comes to growing tomatoes in pots. Too little or too much water can stunt your plant’s growth, contribute to blossom end rot, or encourage pests in times of hot weather or plant stress.

For those same reasons, water only the root zone with a watering can, garden hose, drip irrigation, or soaker hoses (not overhead on the leaves) so you can see exactly how much water your plant is getting each time.

After the initial watering, and depending on the weather, you probably won’t need to water again until three days later. Check the top 3 to 4 inches of soil with your finger; if it feels dry, give it a good drink.

As summer goes on, you’ll want to check the soil a couple times a week to ensure a consistent level of moisture.

Plants in containers tend to dry out more quickly than those in raised beds or in-ground garden beds, so it’s not unusual to water at least once every other day as temperatures climb higher. The smaller the pot, the more often you’ll need to water.

Remember that tomato plants like to be watered deeply, so be sure to saturate the soil until excess water drains out the bottom. Give another nice, long soak only when the top 3 to 4 inches of soil feel dry.

8. Protect young transplants from frost with “walls of water.”

Generally, it’s a good idea to wait until nighttime temperatures are consistently above 45°F before you plant tomatoes outside.

But in climates with short or finicky growing seasons, sometimes you just need to get them outside sooner (or you never know when temperatures may dip below freezing). Here in Central Oregon, it’s not unheard of to get frost well into July!

One way that I protect my transplants in late spring to early summer is with “walls of water” (also known as tomato teepees).

They keep plants nice and toasty and are super easy to use (no need to take frost covers on and off each day).

Cherry tomato plant

Walls of water enable you to plant your tomatoes up to six weeks before your last frost date, and keep them going up to six weeks after the first freeze, as they’re rated to withstand temperatures as low as 16°F.

(They haven’t failed me yet, though I’ve personally never used mine below 28°F.)

They also protect against wind, so they’re useful for delicate young plants that haven’t fully anchored themselves into the soil yet.

“Walls of water” is basically a large ring of heavy-duty plastic that’s sectioned off into long tubes. The tubes are filled with water, and the “walls” are placed over the plant with the weight of the tubes supporting them. You end up with what looks like a teepee around your plant.

(Quick tip: Place the walls of water over a bucket and fill the tubes partway with water until the walls can mostly stand on their own. Transfer the walls to your container over the plant, then continue filling them to the top with water.)

Fill each tube in the plastic tomato teepee with water
Walls of water collect heat during the day and radiate it back out at night

Walls of water act as mini greenhouses, collecting heat from the sun during the day and radiating it back out at night.

They do need to be refilled periodically as the water evaporates, but they’re surprisingly effective in colder climates and I highly recommend using them if you want to get an early start on the growing season.

I usually remove mine once my tomato plants are a few inches above the walls (or I’m certain all danger of frost has passed).

A simple way to remove the tomato teepee is to push all the walls in until water spills out the top and onto the soil.

Once the tubes are mostly empty, you can roll them down, lift them up over the plant, dry them out, and store them for next year. Then proceed with Step 9.

9. Add your support structure.

To reduce your chances of damaging the roots, add your tomato support at this stage before the plant grows too large.

Stake tomato plants early to avoid damaging roots

If you are growing determinate tomatoes, the metal conical cages that you find in most garden centers will suffice. But, I am generally not a fan of them for indeterminate tomatoes, as I find they’re too flimsy to support the long, sprawling vines.

My favorite tomato supports are these tomato ladders (essentially very tall, burly stakes) and square tomato cages (which can be folded down when not in use).

Both of these supports are strong, extendable, and durable (I’ve used the same ones for years and they still look good as new) and they’re also attractive, if you care about that kind of thing.

Vigorous tomato plants in pots

(Quick tip: If you use tomato ladders, you can stake your plants first and then add the “walls of water” over them, making things a little more streamlined.)

Walls of water can be used with stakes and ladders to support tomato plants

They’ve easily supported my container tomatoes that grew over 7 feet tall and are convenient to store away at the end of the season.

I’d say the cages are a little better at containing the vines than the ladders, as you can simply tuck your tomato branches back into the cage if they get too unruly.

Tomato plants thriving in 20-gallon containers

With tomato ladders, you have to stay on top of tying or clipping the vines to the stakes to keep them neat and tidy.

Whichever support you use, don’t wait until you actually need it before you install it. It’ll be that much harder to wrangle a mature tomato plant into a cage than to just have it in place early.

10. Mulch the soil.

Mulching is essential for any garden, but it’s especially important for container gardens as it helps retain moisture in the soil.

Use an organic mulch like straw (not hay, which contains seeds), shredded bark, or arborist wood chips to cover the soil by at least 2 inches, taking care not to bunch it up against the stem.

One substantial layer of mulch should last the whole summer, and can be composted with your spent tomato plants at the end of the season.

Mulch containers to help retain moisture in the soil

11. Fertilize your tomatoes consistently throughout the season.

Even with all that good stuff that you put in the planting hole, your tomato plants will need another shot of nutrients about six weeks into the season.

I like to use a balanced organic fertilizer, like this granular tomato fertilizer or this liquid fish and seaweed emulsion. Follow the package directions for proper application, and keep the fertilizer bag or bottle next to your plants so you’ll never forget to feed them.

Try to avoid high-nitrogen fertilizers, as you’ll end up with lots of lush green leaves, but no flowers or fruits.

How to Grow Tomatoes in Pots Like a Gardening Pro

Growing indeterminate tomato plants in pots

You don't need a lot of space to grow tomatoes. You just need this step-by-step guide that shows you exactly which varieties to grow and how to set your plants up for success.

Prep Time 10 minutes
Active Time 35 minutes
Total Time 45 minutes
Difficulty Easy

Materials

  • 1 tomato seedling or start
  • 10- to 20-gallon container
  • 25-inch heavy-duty saucer
  • 1.5- to 3-cubic feet of high-quality potting soil (depending on container size)
  • 1/2 cup of tomato/vegetable fertilizer
  • 1/4 cup of fish meal
  • 1/4 cup of bone meal
  • 2 aspirin tablets
  • Handful of crushed eggshells
  • 1/2 cup of all-purpose fertilizer
  • 1 Walls of Water tomato teepee (optional)
  • 1 tomato support structure
  • Organic mulch

Tools

  • Trowel
  • Garden snips or scissors
  • Cultivator

Instructions

  1. Choose the right type of tomato. Determinate plants or indeterminate plants? Let your space and length of growing season guide you.
  2. Start with a strong and healthy transplant. Your tomato transplant should've been repotted at least once already and properly hardened off.
  3. Don't be shy with container size, and choose a fabric pot over a plastic pot. You need a minimum 10-gallon container for determinate tomatoes and a 20-gallon container for indeterminate tomatoes. Place a saucer under the container before filling it, and make sure it's in the spot you want it — otherwise it'll be very heavy to move later.
  4. Use high-quality potting soil. Spread about 3 to 4 inches of potting soil across the bottom of the container.
  5. Feed your tomato plant well. Once you add your potting soil, stir the following amendments into the soil: tomato/vegetable fertilizer, fish meal, bone meal, aspirin, crushed eggshells. Then, spread another 2 to 3 inches of potting soil on top.
  6. Bury the stem of the tomato plant. Gently pinch or snip off the lowest sets of leaves until you’re left with a bare stem on the bottom one-third to one-half of the stem. Center the tomato plant in the pot and fill the remainder of the pot
    with more potting soil until it’s filled to the brim (just below the last set of leaves). Gently shake the pot to settle the soil and add more as needed. Top off the soil with 1/2 cup all-purpose fertilizer and lightly rake it in around the base of the stem.
  7. Water thoroughly and consistently. Water the root zone thoroughly until the soil is evenly moist. Water the plant in, wait about 10 minutes, water again, wait 10 minutes again, and repeat until water runs freely out the bottom of the pot. It will take upwards of 1 gallon of water to fully saturate the soil.
  8. Protect young transplants from frost with "walls of water." This is an optional step for cold climates. If nighttime temperatures are consistently below 45°F at the time of planting, fill a Wall of Water and place it over your seedling to protect against frost. Remove the Wall of Water when the tomato plant is a few inches above the walls (or all danger of frost has passed).
  9. Add your support structure. To reduce your chances of damaging the roots, add your tomato support at this stage before the plant grows too large.
  10. Mulch the soil. Use an organic mulch like straw (not hay, which contains seeds), shredded bark, or arborist wood chips to cover the soil by at least 2
    inches, taking care not to bunch it up against the stem.
  11. Fertilize your tomatoes consistently throughout the season. Start feeding your tomato plant about six weeks into the season. Use a balanced organic fertilizer and follow the package directions for proper application.

      Depending on a variety – some tomato plants don’t grow tall (cherry tomatoes), I wouldn’t pinch flowers as these indeed become the fruit. What you need to pinch are the little leaves that grow between the stalk and the branches (in between – a tiny little leaf), as these aren’t needed and by pinching them the plant will spend more energy into growing and baring fruit.

    My question is this- one day I came to my celebrity tomato plant that had already started producing about 3 good sized green tomatoes but all of the very few leaves it had to begin with had all turned yellow. Not sure why. Here are my guesses as to why but would love your input
    1- about two weeks prior at the advice of someone on you tube I poured a lot- like 1/4 to maybe 1/2 of baking soda at the bottom of the plant which is in a container. This seemed like a lot but this is what I was advised to do. I am wandering if that blocked the plants ability to take up nutrients and water. Before turning completely yellow the edges were brown on some which I read could be a sign of this. Or perhaps they got some disease or pest as I read there are many that present in this fashion
    2- perhaps I over watered as I am new and was checking on them every day.
    3- we are going through a heat wave with over 90 degrees for ten days so maybe it was heat stress
    4- not enough nitrogen as even before this happened with the baking soda I had very few leaves growing on the plant
    5- maybe it’s septoria? I think it’s called or some other fungal disease that presents with brownish/yellowing spots and then all leaves turn yellow and fall off.
    Any ideas?
    And any suggestions as to how to save my green tomatoes? Concerned about sun scald as they have very few leaves.
    Should I try to repot the whole thing or is that too risky? All growth and new growth appears to be stunted.
    Oh I also applied calcium nitrate- dissolved and watered it with this again due to you tube advice.. Not sure what I did wrong but would appreciate any experienced gardener who feels they have a good idea of the problem and possible solutions.
    Shout I pick the green tomato and hope it ripens inside?

    Thanks! Sorry for long post.

      Yellow leaves could mean a number of things, including underwatering or overwatering, or nutrient deficiencies. Baking soda is typically used as a diluted spray for plants, so I’m not sure if you mean you just put 1/2 cup of straight baking soda in your container?

      In any case, with temperatures in the 90s, your plants are likely heat-stressed (on top of possible injury from the baking soda), so I’d give them some shade in the afternoon and see if the green tomatoes start to ripen.

      I’m not an expert but this sounds a little like nutrient burn to me. By adding that much baking soda (Sodium bicarbonate) and calcium nitrate to your soil you are adding a lot of salts and nutrients which can do a few things. It can change the PH of the soil which could potentially upset your plant. It could also add basically too many nutrients to the soil causing the roots to have a hard time finding nutrients they need (Nutrient lockout).

      I would suggest just watering it normally for a bit without adding anything to help wash some of the that out and then give it something high in nitrogen until it has put on some leaves to suck up the sun and then switch your fertilizer to something with more Potassium when you feel your plant is healthy enough to start producing fruit. I would also take the current fruit off it so that your plant can put it’s energy into leaf growth.

      Once it has some new leaf growth you can trim off any damaged leaves. Never trim more than a third of the plant at one time.

      When it comes to fertilizer its usually good to pick a fertilizing schedule you like or follow the label of what you are using. In containers you can over feed. Experiments can be good to do be do them one at a time waiting to see results and know that you may loss that plant if the experiment goes badly.

      Good luck. I hope that was some what useful for you.

      Do try again! I’d skip the baking soda – too much baking soda- even it sprays can, as Tracey said, change the pH and it isn’t doing anything. Most of the voodoo we routinely practice on tomatoes is unnecessary. Soil science is complex and when we mess with one aspect without understanding all of it, we can just make things worse. If you’re buying a high-quality potting mix, the pH should be fine. Remember when you decide what to feed it that the plants aren’t eating it- the soil microbes are, and they will enable the plants to take up the nutrients they need – so lots of compost. Around here, it’s what we use for mulch, because the slugs love everything else. And sometimes things just go wrong, so don’t give up.

    Hi, This is my first time planting anything so I decided on tomatoes. I have some in the ground but not many b/c I have stray cats that use it as a litter box. So, I put them in tall garbage pails and small pots. Anyway, they are determinant and I read that you aren’t supposed to prune them at all, but the leaves on the bottom look droopy. Also, are the roots as deep for a determinant plant as indeterminant? The soil is costing me so much money since I have so many plants. And I’m told not to prune the first flowers even though it would cause more energy to be put into the roots. Thoughts? So grateful!!!! Thank you!

      Tomato plants don’t like to be waterlogged and they don’t develop well when watered frequently for short periods of time (as the roots tend to stay near the surface of the soil where all the moisture is). Give them a nice deep soak, then wait until the first 3-4 inches of soil feels dry before you water again. Depending on the size of your pot and your climate, you may need to water your plants 2-4 times a week in summer.

      No, let your plant grow as tall as it wants! But make sure it’s well supported so the branches don’t snap (or become too top heavy for your pot). Thinning out the leaves is not necessary unless you have an issue getting enough air circulation between your plants.

      It depends on your climate. You can download a custom planting calendar here to enter your last frost date: https://www.gardenbetty.com/planting-calendar/

      If you use Walls-o-Water (as shown in my post), you can probably transplant tomatoes now if you’re anywhere south of zone 6. I’ve successfully used Walls-o-Water down to a low of 28°F (with daytime temps in the high 50s-low 60s).

    This is fabulous and so timely. We’re moving this summer and won’t get into our new place until mid-August….. I’m determined to have a few vegetable plants for the rest of the season. It’ll be a short one, but I still want to try (and succeed)! Thanks for posting!

      You’re welcome! I’m in the same boat. Still haven’t transplanted tomatoes (nearing mid-June) but I already know I’ll get a good growing season by putting them in pots rather than in the ground. You have so many more options that way!
