How To Grow Tomatoes (The Step-By-Step Guide)

If you’ve ever bitten into a juicy ripe tomato that you grew yourself, you know there’s nothing quite like it. Not only is growing tomatoes a popular hobby for green thumbs and novice gardeners alike, but it also comes with a plethora of benefits. 

From the satisfaction of watching something grow from a tiny seed to the unbeatable taste of a homegrown tomato, there’s a lot to love about this fruit. 

But don’t let the seemingly easy task fool you- growing tomatoes takes some effort and know-how to produce healthy and flavorful results. 

So, let’s dig in and learn how to grow some delicious tomatoes! 

Types Of Tomatoes To Grow

When it comes to growing tomatoes, you’ve got options. There are three main types of tomatoes to consider: determinate, indeterminate, and heirloom. 

Determinate tomatoes are known for their compact, bush-like growth habit. They tend to produce more fruit all at once, making them a popular choice for canning or preserving. 

Indeterminate tomatoes, on the other hand, keep growing and producing fruit until the first frost hits. They can get quite tall and require staking or support to keep them upright. 

Heirloom tomatoes are a bit of a wild card; they come in a variety of shapes, sizes, and colors and are typically open-pollinated varieties that have been passed down for generations. 

So which type do you choose? Well, it depends on your gardening goals. If you’re short on space or want to harvest your tomatoes all at once, determinate tomatoes might be the way to go. 

If you’ve got plenty of room and want a steady supply of tomatoes throughout the season, indeterminate tomatoes are your best bet. 

And if you’re feeling adventurous and want to try something new and unique, heirloom tomatoes are a fun option to experiment with. 

Choosing The Right Location And Soil

Ok, time to talk dirty! Location and soil. Tomatoes thrive in warm sunny environments, so finding the right spot for them to grow is key.

Aim for a location that gets at least six hours of direct sunlight each day. If you live in a cooler climate, consider planting your tomatoes against a south-facing wall or in a greenhouse to maximize heat absorption. 

But it’s not all about the sun- soil quality is important too. Tomatoes need well-drained soil that’s rich in organic matter.

If your soil is heavy or clay-like consider adding compost, vermiculite, or perlite to improve drainage. And don’t forget about the pH – tomatoes prefer soil that’s slightly acidic with a pH between 6.0 and 6.8.

Now let’s talk about the fun stuff: how to improve the soil.

One easy way is to start a compost pile and add in food scraps, yard waste, and other organic materials. Another option is to till in aged manure or other organic amendments.

And if you’re really serious about soil quality, consider getting a soil test to determine any nutrient deficiencies or imbalances.  

Remember, soil quality can make or break your tomato growing success, so don’t skimp on this step. With a little TLC, you’ll have happy and healthy tomatoes in no time!

Planting And Caring For Tomato Plants

So, you’ve got your location and soil set up; now it’s time to get those tomato plants in the ground!

The best time to plant tomato seeds or seedlings depends on your local climate and growing conditions, but generally speaking, aim for when the soil has warmed up to at least 60°F (15.5°C). This is usually around two weeks after the last frost date in your area.


When planting tomato seedlings, dig a hole slightly deeper than the root ball and add a handful of compost or other organic matter. Gently place the seedling in the hole and fill it with soil. Be careful not to bury the stem too deep. 

If you want to get ahead of the game and start your tomatoes from seed indoors during the winter, you can. Growing from seed gives you access to a lot of varieties of tomato so you can mix things up a bit.

To grow tomatoes from seed, follow these easy steps: 

  1. Fill an egg carton or seed tray with an all-purpose potting mix. 
  2. Make small holes in the soil about ⅛ inch deep using a stick or a pencil.
  3. Pour some seeds into your hand from the packet and put 2 or 3 seeds into each cell. 
  4. Gently cover the seeds with a thin layer of soil and press down lightly. 
  5. Water the seed tray using a light spray to prevent the seeds from surfacing. 
  6. Cover the seed tray with plastic wrap to keep the moisture and warmth in. 
  7. Keep your seedling tray away from direct sunlight and in a warm location. The best temperature for germination is 70-75°F.

Germination will happen 5 to 10 days after sowing when in the correct conditions. Remember to keep the soil moist during this time.

Once the seeds have germinated and the seedlings reach 10 cm high, they are ready to be hardened off outside.

You can harden them off by placing these plants outside in the sun during the day. At nighttime, bring the plants in, as this is the time when the temperature drops. After a week of hardening off, you are ready to transplant them into the ground. 


Now onto the care and feeding of your tomato plants. Tomatoes need consistent moisture to thrive, so aim to water them deeply once a week (more often in hot, dry weather).

Avoid getting the leaves wet to prevent fungal diseases, and consider using a soaker hose or drip irrigation system to keep the soil moist without soaking the foliage. 

Fertilizing is also important for optimal growth and fruit production. You can use a balanced fertilizer (i.e. one with equal parts nitrogen, phosphorus, and potassium) every 3-4 weeks throughout the growing season. 

And don’t forget about pruning- removing suckers (small shoots that grow between the main stem and branches) can help focus the plant’s energy on producing fruit rather than foliage. Finally, let’s talk about pests and diseases. 

Unfortunately, tomatoes are susceptible to a variety of problems, including pests like aphids, hornworms, and whiteflies, as well as diseases like blight and wilt. To prevent these issues, make sure you rotate your tomato plants to a new location each year. 

Keep the area around the plant clean and weed-free and consider using organic pest control methods like companion planting or introducing beneficial insects.

If you do encounter a problem, early detection and treatment are important, so keep an eye out for any signs of trouble and address them promptly.

Harvesting And Preserving Tomatoes

Congratulations, you’ve made it to the most exciting part of your tomato-growing journey: harvesting those juicy red fruits! But how do you know when they’re ready to pick?

Look for signs like a deep red color (or whatever your particular tomato variety is), a slightly soft texture, and a slightly sweet aroma. If you gently pull on the tomato and it comes off easily, it’s probably ready to go!

When it’s time to harvest, use clean, sharp shears or a knife to cut the tomato off the vine, being careful not to damage the stem or nearby fruits. Don’t yank or pull on the tomato, as this can damage the plant and lead to rotting. 

Now onto preserving and strong those delicious tomatoes.

If you have a small harvest, you can enjoy them fresh in salads, sandwiches, or just on their own. But if you have a bumper crop, consider preserving them for later use.

One easy method is to freeze them.

Simply wash and dry the tomatoes, cut them into quarters or halves, and freeze them in a single layer on a baking sheet. Once frozen, transfer them to a freezer-safe container and use them later in soups, stews, or sauces. 

Another option is to can your tomatoes. This requires a bit more equipment and know-how, but it’s a great way to preserve a large harvest for the long term.

You can dice tomatoes, can whole tomatoes, or even make tomato sauce. Just make sure to follow a tested and approved recipe to ensure safety and quality. 

And if you’re short of time or just don’t feel like preserving your tomatoes, you can always give them away to friends or neighbors (or even trade them for other garden goodies). After all, sharing is caring!

Wrapping Up

So, there you have it about everything you need to know to grow, harvest and preserve your own delicious tomatoes. With a little bit of effort and a lot of love, you’ll be the envy of your neighborhood with your bountiful harvest. 

Be sure to select the perfect variety for your space, needs, and growing conditions. When your tomatoes are maturing, keep on top of the pruning to help prevent the risk of pests and diseases. When your tomatoes are pruned correctly, you will be rewarded with plump juicy fruits. 

Whether you’re starting your tomatoes indoors before spring or jumping ahead of time by buying seedlings, you can grow your very own batch of super sweet toms!
