Young your own seedlings rather than buying mature thick-stemmed plants at a garden center. Tomatoes are America’s favorite garden vegetable, and gardeners are enthusiastic about finding new ways to maximize production, stalk thickness and even the. I saw in nursery seedlings that are short but having thick stems. Plant tomato seedlings in spring for one of the best tastes of summer, fresh.
How do I get the tomato stem to grow nice and thick just like the they grow the middle stem gets thin, and then I get a spindly tomato plant that. Here, another tomato growing season is upon us. The way to get thick stems is either to top last years plants and grow them from there or to.

One of the things first time vegetable gardeners ask about when they call or email us is tomatoes – everyone wants to grow their own tomatoes. This is a bit unfortunate as for the most part they are not really suitable for growing outdoors in Ireland and are much better suited to a glasshouse, polytunnel or the Mediterranean, all of which require significant investment.
Having said that homegrown tomatoes are top of the list for difference in flavour from their bland shop bought cousins. You simply can’t compare the taste of a homegrown tomato with the thick skinned supermarket varieties that have been bred for long shelf life and handling qualities rather than what should be most important – their taste.Growing tomatoes may not be for someone who’s having their first go at vegetable growing but if you’re decided it’s for you or are considering a greenhouse or tunnel they will be one of the most rewarding crops you will grow.
We’re covering sowing tomatoes in this article, for planting and tomato crop care please see our ‘How to plant tomato seedlings’ article.
When to sow tomato seeds
Sow in late February to mid March. This may seem a little early (and cold) for heat loving plants but tomatoes need a long growing season for the fruit to form and ripen before light and heat levels fall in Autumn.
If you have a warm and sheltered South facing garden and wish to plant outdoors sow in mid March as plants can’t be placed outdoors till May and earlier sown seedlings will have to spend too long in their pots.
What compost to use?
Use a specially formulated seed compost as it’s lower in nutrients (higher nutrient levels can inhibit germination and damage young roots) and a much finer consistency than potting compost. We use Klassman organic seed compost for our seedlings and reckon you’ll struggle to find better. Available in peat and peat free versions.
You’ll need heat for your tomatoes to germinate with 21˚C being the optimum. Use a heat mat, propagator or soil warming cable to achieve this. You’re ready to go with the first two straight out of the box but if you’d prefer to make your own you can see how to make a soil warming cable heat box here.
I’m afraid I’m a bit lazy when it comes to sowing tomatoes and don’t bother to prick out seedlings and pot them on. I need to feed my tomatoes a little after 4 weeks or so to keep them going before I plant them but I still get very happy plants which produce good yields of tomatoes. It’s a time problem with me, you might want to do it properly so I include both methods below:
Open seed tray method
Sow seeds thinly in an open seed tray (not split into modules, like a small plastic roasting tin) or in a large 9cm pot. Barely cover the seeds with a very light layer of low nutrient fine seed compost (a soils sieve is handy for this), and firm the compost down gently with a wooden tamper.
The seed tray should be kept moist but take care not to over water at this stage. You must also make sure the compost never dries out so a bit of a balancing act here! I find inexpensive bottle top waterers ideal for this job as they deliver a fine accurate spray which won’t soak your compost.
After about 10 days the seedlings should be pricked out and re-planted in a larger 10cm pot filled with a higher nutrient multipurpose potting compost. ‘Pricking out’ means gently removing a seedling by loosening the roots with a dibblet or small stick. Hold the seedling by the seed leaves (cotyledons) and gently lever the root ball out with your dibblet. Re-plant in the new compost with the seed leaves just above the soil level.
The plants should be left on the heat bench at this stage but turn the heat down from 21˚C to about 18˚C (15˚C is the minimum temp for tomatoes at this stage). If plants are grown in individual pots space them out as soon as their leaves touch to prevent them growing tall and spindly.
6 Cell tray method
Most plants you buy from nurseries are grown in 6 cell modular trays. We direct sow 1 seed per call with the plant remaining in the seedling cell until it’s ready to be planted. To be honest you probably will produce a show winning plant with the first method but as long as you feed the seedlings in the lazy method I’d be surprised if it makes much difference in the long run.
For best results sow 2 seeds per cell in a 6 cell modular tray, nip out the weaker seedling with a nail scissors once they have germinated. Tomato seeds can be pricey, especially F1 varieties so if you’re being thrifty you can prick out the spare seedling and re plant in a cell that’s failed to germinate. The same method applies as above, adding a fine layer of compost, firming down and keeping moist.
The difference with sowing in 6 cell trays is you will need to feed your seedlings before you plant them out. As soon as the first true leaves appear (the second set of leaves after the seed leaves) feed with a seaweed tomato feed diluted to half strength. IMPORTANT: Make sure you stick to a half strength mix as overfertilized seedling plants can become stressed and die. Feed again 4 weeks later.
Make sure your propagator is turned down as we’ve said but also make sure your seedlings get plenty of daylight. Clean the glass or plastic on your greenhouse or polytunnel to allow as much light in as possible.
Remember the heat from the propagator comes from the bottom so the foliage of your plants will still be sensitive to freezing night time temperatures. Place a layer of horticultural fleece over the plants on cold nights to keep the heat in and avoid frost damage.
If any flower buds form while in the pot stage nip them off as you want to keep all the energy for growth rather than reproduction a this stage.
Pretend to be the wind
In their natural environment stems will get stronger and thicken up by being moved by the wind, of course this won’t happen in a protected environment indoors. Lightly brush your hands over the tops of the seedlings to jostle them around a bit which will encourage to grow thicker stems and become the sturdy little plants you want them to be. Do this for a minute or so rather than a quick rub on the way past, it’s not a chore, I bet you’ll get benefit just as much as they do!
Red, ripe homegrown tomatoes are the crown jewel in many a vegetable garden. Let this be the year that you can say the same, with luscious fruit grown in your backyard garden, patio or balcony. Follow these tips for the best tomatoes ever.
1. More sun equals more fruit. Choose your sunniest garden spot, because tomatoes soak up sunshine just like water. Aim for seven hours of sunshine a day. Give them room to grow, too, planting seedlings 30 to 48 inches apart, with rows set 48 inches apart. This will let light into the lower portions of the mature plants and improve air flow.
2. Beef up the soil. Tomatoes thrive in rich, well-draining, slightly acidic soil with a pH of 6.5 to 6.8. To determine pH, pick up a soil tester from the Garden Center or your local Cooperative Extension Service. If the soil is too acidic, add dolomite lime. If it’s too alkaline, add sulfur or composted organic matter.
3. Timing is everything. Whether you start your own seedlings or pick them up from the Garden Center, tomatoes like warmth. Wait until soil temps are consistently over 60 degrees Fahrenheit before planting outside. If the weather is still iffy, protect tender seedlings from cold with row covers.
4. Plant deeply. Here’s a neat trick: Tomatoes will root along their stems. With leggy transplants, dig a trench and lay the stem sideways, bending gently upward. Snip or pinch off the lower branches and cover with soil up to the first set of leaves. This extra root growth will produce a stronger, more robust plant.
5. Invite friends to the party. Basil, garlic and onions are a tomato’s best friends in the kitchen, and in the garden, too. Grown together, they’re said to repel pests such as nematodes.
6. Water deeply and mulch, mulch, mulch. Juicy jumbo tomatoes need water, about an inch a week. A blanket of mulch — anything from shredded pine bark to grass clippings and composted leaves — will keep the water from evaporating in summer’s heat. A soaker hose is an efficient solution; just position the hose in the garden and pile mulch up and over the hose.
7. Offer a cup of (compost) tea. Add the benefits of nutrient-rich compost to keep heavy-feeding tomato plants happy. Soak one part organic compost in one part water, let sit for 24 hours, filter the “tea” and use to nourish plants.
8. Pruning is for suckers. Tomato plants send out suckers — leaves that shoot out from the main stem. “Suckering” tomato plants, or removing the suckers, makes sense because it promotes air circulation, keeps down disease and focuses the plant’s energy on growing fruit. Small leaves and tender stems can be pinched off with your fingers; pruning snips give a clean cut to thick stems.
9. Stake or cage. Keep in mind that there are two main types of tomato plants: determinate, the compact plants that fruit all at once, and indeterminate plants that produce throughout the season. Neat, self-contained determinate bushes keep to themselves, but don’t even think about not supporting indeterminate plants. They will grow uncontrolled, with fruit grazing the ground. Cage or stake plants early, before they get out of hand.
10. Forget the windowsill. The lush color that signifies a ripe tomato comes from warmth, not light. If summer’s temps are too cool, go ahead and pick fruit that’s red-orange and bring it inside to ripen. The time-honored tradition of lining up your garden’s best fruit along a sunny windowsill isn’t the speediest way to ripen it. Putting unripened tomatoes in a loosely closed paper bag is a better solution.

Bumpy Tomato Stems: Learn About White Growths On Tomato Plants
Growing tomato plants definitely has its share of problems but for those of us who adore our fresh tomatoes, it’s all worth it. One fairly common problem of tomato plants are bumps on the tomato vines. These bumpy tomato stems may look sort of like tomato acne or may look more like white growths on the tomato plants. So what does it mean if the tomato stem is covered with bumps? Read on to learn more.
What are White Bumps on Tomato Stems?
If you are seeing white growths or bumps on the tomato plant stems, all you are probably seeing are roots. Really. Bumps start out as hundreds of tiny hairlets protruding up and down the length of the stalk. These hairlets can turn into roots if they are buried in the soil.
Above ground, they become nodules. These nodules are called root initials, adventitious roots or tomato stem primordial. Basically, they are the earliest developing roots.
What Causes Bumps on Tomato Vines?
Now that we have ascertained what the bumps are, I bet you wonder what causes them. Just as stress can exacerbate or bring on a bout of acne, stress also causes bumps to form on the tomato stalk. Usually, the stress means there’s a blockage in the stem’s vascular system. The plant sends out a hormone called auxin to the tomato’s roots when there is a blockage in a branch. The hormone accumulates in the stem due to the blockage, forming a bump.
A number of stressors can engender bumpy tomato stems. Among these are root damage, internal injury, irregular cell growth, high humidity and probably the most common stress is too much water, either from over watering or after a deluge, especially if the plant lacks drainage. Sometimes, diseases can result in a tomato stem covered with bumps. These root initials may be white, brown or the same green as the stem.
Bumps may also be caused by exposure to an herbicide. If you see swelling on the stems, check the leaves. If they are curled or stunted, the plant may affected by an herbicide. Even if you aren’t using one, your neighbor may be. Herbicides can act much like the tomato’s own hormone, auxin, resulting in not only curled leaves but bumpy stems.
What Can Be Done about Bumpy Tomato Stems?
Most of the time there is no need to do anything about bumps on the stems of a tomato. They don’t harm the plant in the slightest. In fact, you can utilize these root initials to help strengthen the plant, simply mound soil around the lower root initials. They will develop into mature roots which, in turn, will strengthen the plant.
If you have accompanying wilt, it’s likely that the area is too wet and you have either overwatered or drainage is bad and there has been an abundance of rain. Adjust your watering and be sure to plant your tomatoes are in well-draining soil.
Wilting can also be an indication of something more sinister such as with fusarium wilt or verticillium wilt. This is also accompanied by brown leaves, stunted growth, as well as yellowing and black streaking of stems. Fungicides may help if caught early enough, though pulling up plants and disposing of them may be a better option should this be necessary.

You go out to your garden, begin checking out your tomatoes plants, and picking some great looking tomatoes. Then all of a sudden you notice that the main stem of your plants are covered in little tiny bumps. Don’t worry too much, those bumps are not a big threat in most cases.
What Are These Bumps On My Tomato Plant?
If you look closely at a tomato stem, you will notice hundreds, if not thousands, of little tiny hairs.
These hairs will turn into roots when buried underground. That is why it is advantageous to plant tomatoes deep.
By planting your tomatoes deep, those hairs will grow into roots, creating a stronger and healthier root system.
When these hairs are above ground, they will form tiny bumps (often called Tomato Stem Primordia) on the stems of the plant.
The Tomato Stem Primordia are the earliest stage of development of the roots. The bumps are caused by high humidity, predominantly wet weather, or overwatering. The bumps themselves are not harmful to your tomato plants, and are usually deemed as normal.
Watch Plants Closely If You Find Bumps On The Stems
Bumps on the stems can also be a sign of root problems, so keep a close check on your plants. This is usually not the case, but it doesn’t hurt to watch for any signs of wilting, browning leaves, or that the plant’s growth is hampered.
