You’ve seen the photos. Those heavy, deep-red heirlooms leaning against a weathered garden fence, looking like they’ve been kissed by the sun itself. Then you look at your own backyard. Maybe there’s a spindly vine with three yellowing leaves and a single, rock-hard green orb that refuses to ripen. It’s frustrating. Honestly, it’s enough to make you want to stick to the flavorless, mealy grocery store stuff. But here’s the thing: the best way to grow tomatoes isn't about buying the most expensive fertilizer or having a "green thumb." It is about understanding the weird, specific biology of a plant that is actually a tropical perennial masquerading as a summer annual.
Most people treat tomatoes like marigolds. They aren't marigolds. They are greedy, sun-worshipping, water-obsessed divas.
It All Starts Underground (And Deep)
If you’re just digging a small hole and plopping the root ball in, you’re already behind. Stop doing that. The secret—and I mean the literal foundation of success—is burying the stem. Tomatoes are one of the few plants with "adventitious roots." That’s just a fancy way of saying they can grow roots out of their skin. If you have a seedling that is ten inches tall, bury seven inches of it. Strip off the lower leaves and sink it deep.
Why? Because a massive root system is the only thing that stands between you and a dead plant during a July heatwave. More roots equal more water uptake. More water uptake equals more fruit. It's basic math. Craig LeHoullier, the guy who basically rediscovered the "Cherokee Purple" heirloom, emphasizes that soil health and root volume are the non-negotiables. He’s right. If the soil is compacted, the roots can't breathe. If they can't breathe, the plant stalls.
The Nitrogen Trap
We need to talk about fertilizer. You’ve probably been told to use a high-nitrogen "start" fertilizer to get things moving. That’s a mistake. While nitrogen produces beautiful, lush, forest-green leaves, it does absolutely nothing for the actual fruit. In fact, if you overdo the nitrogen, you’ll get a giant, beautiful bush with zero tomatoes.

What you actually want is phosphorus and potassium. Look for the N-P-K numbers on the bag. You want that middle number to be the star. And don't forget calcium. If you’ve ever seen a tomato with a disgusting, sunken black bottom, that’s blossom-end rot. It isn't a disease; it’s a localized calcium deficiency caused by inconsistent watering. The plant can't move calcium to the fruit if the soil keeps drying out and then getting flooded.
Sunlight Is Not a Suggestion
Six hours of sun? No. That’s the bare minimum for survival. If you want a harvest that makes your neighbors jealous, you need eight to ten hours of direct, unfiltered light. Anything less and the plant gets "leggy." It starts reaching for the sky, stretching its internodes, and becoming structurally weak.
Positioning matters. If you live in a place like Texas or Arizona, you might actually need a bit of afternoon shade to prevent "sunscald," where the fruit literally gets a sunburn. But for most of the northern hemisphere, you want every photon you can get.
Pruning: To Snip or Not to Snip?
This is where gardeners start fighting. There are two types of tomatoes: determinate and indeterminate.

Determinate varieties (like Roma or Celebrity) grow to a certain height, produce all their fruit at once, and then give up. Do not prune these. You’re literally cutting off your harvest.
Indeterminate varieties (like Brandywine or Sun Gold) are vines that will grow twenty feet long if you let them. These require a firm hand. You have to find the "suckers"—those little shoots that grow in the V-shape between the main stem and a leaf branch. Pinch them out. If you don't, your garden will become an impenetrable jungle. Airflow is your best friend. Without it, you get Septoria leaf spot or Early Blight, and once those fungal spores take hold, it’s game over.
The Best Way to Grow Tomatoes in 2026
Modern gardening has changed. We have better tools now. In 2026, the best way to grow tomatoes often involves "EarthBoxes" or similar sub-irrigated planters if your backyard soil is trash. These systems use a water reservoir at the bottom, which keeps the moisture levels perfectly consistent. It eliminates the "feast or famine" watering cycle that kills so many plants.
If you are planting in-ground, mulch is your religion. Use straw. Use shredded leaves. Use wood chips. Just cover the soil. Bare soil splashes fungal spores onto the lower leaves when it rains. Mulch acts as a barrier. Plus, it keeps the roots cool. A tomato's roots hate being hot as much as its leaves love the sun. It’s a weird contradiction.

Real Talk on Varieties
Stop buying "Beefsteak" just because the name sounds cool. If you live in a short-season climate like Vermont, a 90-day heirloom will die before it even thinks about ripening. Look for "Days to Maturity."
- For Beginners: Get a "Sun Gold" cherry tomato. They are virtually indestructible and taste like candy.
- For Flavor Snobs: "Black Krim" or "Mortgage Lifter." These have a smoky, complex acidity that a hybrid can't touch.
- For Canning: "San Marzano." They have less water and more meat.
Disease Is Not Failure
Sometimes, despite doing everything right, your plant will get Wilt. It happens. Fusarium and Verticillium wilts live in the soil for years. If your plant starts wilting from the bottom up even though the soil is wet, it’s likely a soil-borne pathogen. The only solution is to rotate your crops. Never plant a tomato where a tomato (or pepper, or potato) was last year. Wait three years.
Actionable Steps for Your Garden
Success isn't about luck. It's about a series of deliberate choices you make before the plant even hits the dirt. If you want to master the best way to grow tomatoes, follow this sequence:
- Test your soil's pH. Tomatoes want it slightly acidic (6.2 to 6.8). If your soil is too alkaline, the plant can't "unlock" the nutrients even if they are present.
- Hardening off is mandatory. You can't take a seedling from a warm windowsill and put it in the wind and sun immediately. It will go into shock. Give it an hour outside the first day, two the second, and so on.
- Water the soil, not the leaves. Wet leaves are an invitation for fungus. Use a soaker hose or be very careful with the watering can.
- Support them early. Don't wait until the plant is falling over to stake it. Use heavy-duty cattle panels or thick wooden stakes. Those tiny cone-shaped cages from the hardware store are useless for anything bigger than a dwarf variety.
- Harvest at the "breaker stage." Once a tomato is about 30% to 50% changed in color, you can pick it. It has all the sugars it needs. Let it finish ripening on your kitchen counter. This protects it from birds, squirrels, and cracking due to sudden rain.
Tomatoes are a labor of love. They require attention, pruning, and a bit of dirt under your fingernails. But when you bite into a warm, sun-drenched fruit that you grew yourself, you'll realize the grocery store has been lying to you your whole life. Get started now. The soil is waiting.
