These five tomato growing tricks will help you grow your best tomatoes ever this summer!
Last updated: May 8, 2019
If you’re like most people, tomatoes are probably the first thing that comes to mind when you think of a garden.
There are thousands of varieties of edible fruits, veggies, roots, tubers, herbs, edible flowers, mushrooms, and grains that might adorn your garden throughout the year. However, tomatoes have managed to capture the American gardener’s imagination more than any other type of produce.
Perhaps it’s due to the piles of showy, delicious fruit a tomato plant can produce in a relatively short period of time. Or perhaps it’s because tomatoes are quiet, juicy geniuses who have domesticated human beings so that we’ll take care of them and spread their seeds throughout the world.
Whatever the case may be, if you plan to have a summer garden, you’re probably going to be growing tomatoes. If so, here are five tomato growing tricks we’ve learned over the years that will boost your yields and save you time and money…
5 Tomato Growing Tricks That Will Make You a Better Gardener
These tomato growing tricks are arranged chronologically based on the order in which you do them:
Tomato Growing Trick 1: Learn to start your own plants from seed
This might not seem like a “trick,” but once you master seed starting, it can save you more money than perhaps anything else you’ll ever do in your garden while also allowing you to grow any variety of produce you want, not just what your local garden center happens to carry.
A packet of USDA certified organic tomato seeds will cost you about $3-4 depending on how many seeds are in the packet. Most usually have at least 25 or more seeds. That means you could grow a minimum of 25 tomato plants that could each produce a pile of tomatoes for you in a few short months.
Considering that the average beefsteak tomato plant will produce 15 – 25 pounds of fruit, that single packet of seeds could give you a yield of 625 pounds of fruit. If you go to a store and buy a pound of crummy hothouse tomatoes, you’re going to pay $3/lb; if you buy a pound of certified organic heirloom tomatoes, you’re probably going to be paying closer to $6/lb.
So, if you expertly use 25 seeds to grow 625 pounds of your own organic, heirloom tomatoes, you just grew $3,750 in tomatoes!
New tomato seeds for future years
Also, if you’re growing heirloom tomatoes (which are always open-pollinated), you can save enough seeds from your tomatoes to give a seed to every person on earth after about two growing seasons (seriously, do the math!). See why heirloom/open-pollinated seeds are the gift that keeps on giving?
“Sure,” you’re thinking, “but what about the time and cost involved in growing tomatoes from seed?”
We grow our own tomato seedlings with minimal time and investment. We reuse our durable Bootstrap farmer seed cells and flats, so our primary cost is the organic seed starting mix.
Since we grow so much food, we built our own indoor grow light setup for about $300, but this is an investment that more than pays for itself each gardening season — and we garden in all four seasons every year.
Why not get tomato seedlings or plants from a garden center?
Now, consider this: if you go to a garden center and get a tomato plant/seedling, you’re going to pay somewhere between $4-10 per plant depending on where you live, the variety of tomato, and the size of the plant.
There’s a pretty good chance that you’re only going to be able to buy a hybrid tomato plant, which means you won’t be able to save seeds that will grow the same type of tomato again next year. There’s also a good chance the plant was treated with a systemic pesticide soil drench like a neonicotinoid, which over 800 peer reviewed scientific studies say kill birds, bees and other beneficial critters even when used as recommended by the manufacturers.
That’s the most expensive tomato plant you could possibly grow in your garden.
Tomato Growing Trick 2: Buried Stems = Better Roots
See those fuzzy tomato stems? As it turns out, tomato stems can form adventitious roots if they’re planted in the soil. Larger, deeper root systems mean less water and fertilizer inputs, healthier plants, and larger fruit yields.
Now, the first time you do this trick, you’ll feel like you’re murdering your plants, but it will pay off big time.
Here’s what you do when you’re ready to transplant your tomato seedlings:
1. Remove lower branches
Cut off all the lower branches on your seedling, leaving only the top few branches and the growth tip.
2. Dig a trench
Dig a trench larger enough to lay your tomato seedling down sideway while still giving the first stems enough room to stick out a few inches above the soil surface.
By laying the plants sideways, you’ll help them develop better vertical roots. This is especially helpful if you have leggy seedlings.
It’s also better to dig a vertical trench rather than a deeper horizontal hole to bury your tomato transplants. That’s because tomatoes are heat-loving plants.
The deeper you bury the root ball and stem, the cooler the soil will be, which will slow its growth. A horizontal trench keeps the plant in the warmer, upper levels of the soil.
3. Bury the stem and lay the plant sideways
Add some worm castings (these are the best quality and most affordable worm castings on the market) or finished hot compost into the hole. This will provide your tomato plants with biological fertility via beneficial microbes that also help protect the plants from pathogens.
Don’t use synthetic nitrogen fertilizer products since these are bad for the long term health of your soil and have also been proven to make your plants more attractive to pest insects. Once your trench is ready and you’ve added a good microbe-rich media (worm castings or compost), bury the tomato plant and stem up to a few inches below the first branches.
Your buried tomato stems will soon produce new roots and you’ll end up with plants that will outgrow and outperform a shallow rooted tomato plant.
Tomato Growing Trick 3: The “Stick Trick”
The “stick trick” is especially important if you’re growing your own seedlings rather than buying mature thick-stemmed plants at a garden center.
Cutworms are the bane of many farmers’ and gardeners’ existence. They’re the seedling-munching larvae of Noctuidae moths.
Cutworms can make you think evil, murderous thoughts when you go out on a spring or summer morning to find your once beautiful, healthy seedlings chopped down and lying dead on the ground. Our first year of gardening, we lost a bunch of plants this way. So we set out for revenge…
Surely, our brains could outsmart a moth baby’s brain without resorting to using pesticides, right? Yep. And the solution is stupid simple, free and 100% effective if you do it right.
Here’s how to stop cutworms in your garden:
When you transplant your young seedlings, gently insert a stick (about the size of a toothpick or slightly larger) into the ground right next to the stem of your seedling.
The larvae will feel around the stem of your plant, detect the stick and be fooled into thinking that the plant’s stem is too tough to chew through. Then it will move on in search of another victim.
We use the “stick trick” on all the spring/summer plants that we start indoors and transplant: melons, squash, cukes, tomatoes, eggplants, peppers, etc. We have yet to lose a single plant to cutworms when using this technique.
Tomato Growing Trick 4: Got Mulch?
Many people talk themselves out of gardening by saying I don’t have time to plow, water, weed, fertilize, etc.
Great. Neither do we.
- We haven’t plowed our soil in seven years. In fact, we don’t ever plan to till our soil again because of how destructive it is to the soil ecosystem.
- We only water during periods of drought or when our seedlings are very young.
- The only weeds we have are in the few patches of grass we have left, and many of those “weeds” are edible plants that we eat.
- We don’t use conventional fertilizers; instead we focus on long-term biological soil fertility. This is because we have a pretty good appreciation for the living systems that make soil work (the soil food web).
We feed our soil what it knows how to eat and our soil feeds our plants what they know hot to eat so that our plants can feed us what we know how to eat.
Soil is like the skin on your body: it’s a protective organ. Scrape off your skin, and a scab will form.
Likewise, nature does not tolerate having its soil scraped off and exposed to the elements. Uncovered soil will soon begin healing via “weeds,” nature’s scabs, aka the pioneer plants in plant succession.
In your garden or farm, you have two options:
- always cover your soil with the plants and/or mulches of your choosing; or
- be prepared to let nature cover her own soil with the plants of her choosing.
You probably won’t like option #2, and it usually causes conventional gardeners and farmers to engage in perpetual chemical warfare.
We like using a combination of green mulches (cover crops), fall leaves, and wood chips that we get free from local tree service companies. All three types of mulch will drastically improve your soil biology/fertility, and can eventually replace your need to fertilize.
Especially if your soil is young, we’d recommend you take things a step further by also using some combination of worm castings, hot composted compost (aka using the Berkeley method), compost teas and really good mycorrhizal inoculants like this one.
Our personal favorite mulch to top-dress our garden beds with is wood chips, which we get for free from local tree service companies. Wood chips form an insulating surface on your soil surface, reducing soil temperature fluctuations and plant stress, while increasing water penetration and retention.
Wood chips also prevent weed seeds in your soil seed bank from germinating and growing in your garden beds. Less work + less inputs + less money spent + more and better food. That’s our kind of gardening!
IMPORTANT NOTE: Top Dress With Wood Chips, Do NOT Plow Them Into Your Soil!
We top-dress our beds with about 3-4″ of wood chip mulch twice per year, and let the soil microorganisms slowly convert the wood chips into bioavailable nutrients that they bring down to our plant roots for us. The plants also feed the microbes all kinds of goodies in return via their root exudates.
It’s very important to note that you do not want to plow the wood chips into your soil, or you’ll lock up the nitrogen in your soil as the soil microorganisms borrow it while they digest the carbon. Low nitrogen = plants that don’t grow. So, just put the wood chips on top of the soil surface and let nature do the rest of the work for you.
Mulch also reduces tomato foliar diseases
Many common tomato foliar (leaf) diseases are caused by rain splashing soil pathogens onto the lower leaves of the plants. Well, you’ll also be pleased to know that using wood chip or other mulches reduces or eliminates this problem too.
When transplanting your tomato seedlings into your mulched garden beds, simply pull back the mulch from the planting spot, make a small hole and plop it in the ground (see trick #2 above). You can do the same thing when you direct sow, but only make a hole big enough for the type of seed you’re planting.
Tomato Growing Trick 5: Don’t Get Suckered
What the heck is “tomato suckering”? As tomato plants grow, they’ll produce a branch and a “sucker” between the stem and the branch. The sucker grows like a new stem, producing new branches and suckers along the way.
Many people tell you that you have to remove the suckers to reduce plant diseases and get the biggest fruit from your tomato plant. The idea being that more air can flow through your plants and the plant will put more energy into fewer fruits.
If you’re trying to grow the world’s biggest tomato and you have the time to remove all the suckers as your tomato plant grows, then you might want to go ahead and sucker your plants (and be sure to sanitize your tools as you go so you don’t spread diseases).
However, if you’re growing more than one tomato plant and you’re into low-maintenance gardening like we are, you don’t need to sucker your tomato plants. You might end up with slightly smaller tomatoes on your beefsteak varieties, but if you’ve got good soil and healthy plants, you’re probably not going to notice a dramatic difference in fruit size.
Also, one of the fastest ways you can spread diseases throughout your tomato plants is by constantly touching them, cutting them with non-sanitized clippers or other tools that have pathogens on them, and/or leaving exposed wounds on the plants where you removed the suckers.
In our opinion: suckering simply isn’t worth the time and effort relative to the supposed benefits, so don’t be suckered into suckering!
