Want tomato plants that grow like they’re on steroids? I was shocked to discover that the secret to spectacular harvests isn’t fancy fertilizers or rare varieties.
It’s simply planting your tomatoes sideways. This game-changing technique creates root systems so powerful that your plants will flourish like never before. The best part? It takes zero extra effort!
Why Sideways Planting Creates Tomato Powerhouses
The game-changer for your tomato harvest isn’t what you think. Most people make this mistake with their tomatoes: planting them straight down in deep holes. But here’s the botanical truth: tomato stems can actually form roots when buried!

When you plant sideways, you’re essentially giving your tomato a secret superpower. A horizontal stem develops roots along its entire buried length, creating a root system up to 3x larger than traditional planting.
This transforms your ordinary seedling into a nutrient-absorbing machine. (Trust me, your tomato is trying to tell you something important: “I can grow roots from my stem—let me lie down!”)
Step 1: Choose Tomato Varieties That Will Thank You For Going Horizontal
Before digging a single trench, you need the right tomato varieties. Forget what you’ve heard about all tomatoes being equal. They’re not! For sideways planting success, look for:
- Indeterminate varieties – These continuous growers will maximize the benefit of extra roots
- Disease-resistant types – Look for labels with “VFN” resistance coding
- Climate-appropriate options – Match varieties to your growing zone for best results
Heirloom varieties like ‘Brandywine’ and ‘Cherokee Purple’ respond particularly well to sideways planting, often producing up to 40% more fruit than when planted conventionally.
Step 2: Create Soil That Feels Like a 5-Star Resort for Roots
Your tomato’s dramatic transformation begins with luxurious soil. Think of soil preparation like setting up a gourmet buffet. Your hungry plants need all the right offerings!
Mix in 2-3 inches of compost or aged manure to create a nutrient-rich environment. The difference between amateur and pro plant parents is simply soil pH.
Tomatoes thrive in slightly acidic soil with a pH between 6.0 and 6.8. A simple soil test kit from your garden center will tell you if adjustments are needed.
Pro tip: Add a handful of crushed eggshells to each planting trench. The calcium prevents blossom end rot, a common tomato ailment that can ruin your harvest.
Step 3: Dig the Trench That Will Revolutionize Your Garden
Now for the fun part! Instead of digging a deep hole, create a shallow trench about 6 inches deep and long enough to accommodate most of your plant’s stem.

Think of it as a cozy bed where your tomato will stretch out and send roots downward from multiple points.
The ideal trench should be oriented east-west if possible, allowing the exposed plant top to receive maximum sunlight as it grows upward. This simple orientation hack can increase photosynthesis efficiency by up to 15%!
Step 4: The Sideways Magic Moment (Where Everything Changes)
This is where the magic happens! Remove the lower leaves from your tomato seedling, leaving only the top 2-3 sets of leaves.
Gently lay your plant in the trench like it’s taking a nap: root ball at one end, leafy top bent carefully upward at the other.
Cover the horizontal stem with 2-3 inches of soil, leaving only those top leaves exposed.
Within days, your plant will begin a remarkable transformation, developing new roots all along the buried stem. It’s like giving your tomato extra straws to drink nutrients!
(Between you and me, this is the moment most gardeners get wrong. They plant vertically and miss out on all those bonus roots!)
Step 5: Support Your Overachiever For Massive Production
Your sideways-planted tomato is now positioned to grow like Jack’s beanstalk, but it needs support to reach its full potential. Within 1-2 weeks of planting, install a sturdy cage or stakes to support the inevitable heavy fruit load.
The secret most plant experts won’t tell you is that proper support should be installed BEFORE your plant needs it. Trying to cage an already sprawling tomato plant is like trying to put pants on a toddler who’s running away, nearly impossible!
Water deeply but infrequently, about 1-2 inches per week, to encourage those new roots to grow deep and strong. Remember: roots searching for water grow more extensively than roots sitting in moisture.
The Results Will Make You A Sideways Planting Evangelist
Gardeners who switch to this method report harvests that are truly stunning, often 30-50% larger than those achieved with traditional methods. Your tomato plants will be more drought-resistant, disease-resistant, and productive than ever before.

The best part? This technique works its magic whether you’re growing in raised beds, traditional garden plots, or even large containers. It’s like getting a free tomato plant upgrade with no extra cost!
So this season, lay those tomatoes down and watch them reach new heights. Your only problem will be finding enough recipes for all those extra tomatoes!
