Tomatoes come with more advice than almost any other garden crop, and a lot of it gets repeated so often that it starts to sound like fact when it’s actually tomato myths. I’ve followed plenty of that advice over the years, sometimes because it made sense, and sometimes because everyone else was doing it.
After growing tomatoes season after season in Florida, and after plenty of trial, error, and observation, I’ve realized that some of the most common tomato myths or “rules” don’t actually hold up here. They’re not always wrong, but they’re often incomplete, oversimplified, or pulled out of context.

These are five tomato myths I see all the time, why they don’t work the way people think they do, and what actually matters instead.
Tomato Myth #1: Blossom End Rot Means Your Soil Lacks Calcium
Blossom end rot gets blamed on calcium deficiency almost immediately, and while calcium is involved, the soil itself is rarely the real issue, especially in Florida. I’ve had my soil tested multiple times, in raised beds, in ground beds, even around fruit trees, and calcium has never been the limiting factor.
Blossom end rot happens when the plant cannot uptake calcium consistently, not when calcium is missing altogether. That distinction matters. In Florida, inconsistent moisture is usually the culprit. Heavy rain, overwatering, or rapid swings between wet and dry conditions interrupt calcium uptake, even when plenty is present in the soil.
Adding things like eggshells or Epsom salt doesn’t fix the underlying problem. In fact, during rainy periods, you can keep adding calcium and still see blossom end rot because the nutrients are being flushed or diluted faster than the plant can access them.
The most reliable way I’ve reduced blossom end rot is by growing tomatoes during drier parts of the season, using thick mulch, and backing off irrigation when rainfall is frequent. Consistency matters more than supplements.
Tomato Myth #2: Vine Ripe Tomatoes Always Taste Better
These tomato myths gets defended fiercely, but the science and my own taste tests tell a more nuanced story. Picking tomatoes fully green does result in inferior flavor, especially when they’re forced to ripen artificially. But that’s not the same thing as picking them at the blush stage.
Tomatoes picked when they’ve started to change color can finish ripening off the plant without sacrificing flavor. Studies show that once a tomato reaches that blush stage, the difference in sweetness and acidity compared to vine ripened fruit is minimal to undetectable.
In Florida, leaving tomatoes on the vine until fully ripe often means sacrificing them to pests or sun damage. Picking at blush protects the fruit and still delivers excellent flavor once ripened indoors. I’ve done side by side taste tests, and while fully green tomatoes are noticeably inferior, blush harvested tomatoes consistently hold their own.
Vine ripe sounds romantic, but practical gardening sometimes tastes just as good.
Tomato Myth #3: You Must Prune Tomato Suckers
This one tends to upset people.
Pruning suckers is often presented as universal advice, but it depends heavily on your climate and growing season. Determinate tomatoes should not be pruned at all. Removing growth from them directly reduces yield.
With indeterminate tomatoes, pruning can speed up ripening, but it also reduces the total number of flowers and fruits. In climates with short growing seasons, that tradeoff can make sense. In Florida, where the season is long, it often doesn’t.
I stopped removing suckers years ago and saw an increase in overall productivity. Those suckers become branches, and those branches produce flowers. More flowers mean more tomatoes. I do selectively remove leaves to improve airflow and reduce disease pressure, but I don’t automatically strip suckers just because they appear.
Pruning is a tool, not a rule. Used incorrectly, it can cost you harvest.
Tomato Myth #4: Burying Food Scraps Feeds Tomatoes Directly
Eggshells, fish heads, banana peels, compost tea myths, this category is full of well meaning advice. Burying organic material in the garden isn’t harmful, but it doesn’t feed tomatoes in the way people think it does.
Plants can’t access nutrients from raw food scraps until they break down completely, and that process takes months. Often, the nutrients benefiting your tomato plant are from compost or scraps added the season before, not what you just buried.
For annual crops like tomatoes, which may only live six months, relying on raw organic matter is rarely enough. Compost works because it has already gone through the breakdown process. Fertilizer works because nutrients are immediately available.
There’s nothing wrong with burying scraps, but expecting them to replace compost or fertilizer during the same season sets unrealistic expectations and makes this one of the biggest tomato myths.
Tomato Myths #5: Planting Tomatoes Deeply Is Necessary
Planting tomatoes deeply or sideways is often treated as a must do step, but in backyard gardens, the benefits are usually minor. Trials comparing deep planted, sideways planted, and normally planted tomatoes show very small differences in yield and root development.
In my own side by side comparisons, I couldn’t see a meaningful difference. What mattered far more was weather, watering consistency, and disease pressure. This past fall, with drier conditions and less rain, I had one of my most productive tomato seasons ever, despite planting tomatoes at normal depth and skipping extra planting steps.
Deep planting doesn’t hurt, but it’s not the deciding factor in success. In many cases, it adds work without adding results.
What Actually Made the Biggest Difference
The biggest improvements in my tomato harvest didn’t come from tricks or hacks. They came from paying attention to climate, rainfall, and timing. A drier season reduced disease. Consistent watering prevented stress. Mulch stabilized moisture. Choosing the right planting window mattered more than any single technique.
A lot of tomato advice isn’t wrong, it’s just not universal. What works in one region can fall apart in another. Florida gardening rewards flexibility, observation, and a willingness to question advice that doesn’t match what you’re seeing in your own beds.
Tomatoes don’t need perfection. They need conditions that make sense where you live.
