Pruning Your Tomato Plant
How To Grow Tomatoes
It’s easiest to buy tomato seedlings from your local nursery or garden center rather than starting from scratch with tomato seeds. You want to buy seedlings that look healthy with bright green leaves and sturdy stems. Tomatoes grow best with some room, so the number of plants you buy will depend on how much space you have. Start seedlings out indoors in a room temperature area, and once the germination starts , move them to a sunny spot or under grow lights.
If you don’t want to go through the transplanting process, most stores will also have some determinate tomatoes, like cherry tomatoes, already planted in a larger container. With those tomatoes, all you have to do is place the container in the sun, water it and wait patiently.
Check your USDA hardiness zone for the best general time to start tomatoes- it’ll usually be in late spring or early summer. Make sure not to plant them until after the last frost date. The soil needs to be at least 60 degrees in the daytime and 50 degrees overnight before you plant tomatoes.
Prepare your growing location by checking the sun and getting the garden soil ready. You want the plants to get at least six hours of direct sunlight every day . The best tomatoes tend to come from plants that get eight hours of sun. If it’s particularly hot in the direct sun, you may want a row cover to provide shade during part of the day so that the plants don’t dry out.
How To Grow Tomatoes From Seed
Because tomatoes are warm-season plants that take a long time to mature, they are often started from seeds indoors, at least six to eight weeks before the last spring frost. This can be the only way to grow certain organic heirloom varieties, where nursery plants are not available at all.
In a cell tray filled with potting soil, sow the seeds 1/2 inch deep. Place the tray in a well-ventilated sunny area that’s at least 70 degrees. Experienced gardeners often use a heat mat and small fan to provide ideal conditions. Within five days or so, the seeds should sprout. Keep the seedlings warm and moist until they are 2 to 3 inches tall, at which time they can be transplanted into larger pots. Continue to grow in bright, sunny conditions until the weather warms and all danger of frost has passed.
To aid the transition outdoors, “harden off” the young plants by giving them increasingly long visits to outdoor conditions over a period of seven to ten days, bringing them indoors at night. Tomatoes are very sensitive to cold, so they need to be slowly acclimated to outdoor conditions in order to avoid shock.

The Best Tomatoes For Containers
Flip through any seed catalog and youll quickly discover that there are a lot of varieties available to gardeners. Many of my own favorites are featured in my award-winning book, Veggie Garden Remix. And while any variety can be grown in a container if given the right-sized pot, support, and care, certain varieties really are the best tomatoes for containers.
Add Your Support Structure
To reduce your chances of damaging the roots, add your tomato support at this stage before the plant grows too large.
If you are growing determinate tomatoes, the metal conical cages that you find in most garden centers will suffice. But, I am generally not a fan of them for indeterminate tomatoes, as I find theyre too flimsy to support the long, sprawling vines.
My favorite tomato supports are these tomato ladders and square tomato cages .
Both of these supports are strong, extendable, and durable and theyre also attractive, if you care about that kind of thing.
Theyve easily supported my container tomatoes that grew over 7 feet tall and are convenient to store away at the end of the season.
Id say the cages are a little better at containing the vines than the ladders, as you can simply tuck your tomato branches back into the cage if they get too unruly.
Whichever support you use, dont wait until you actually need it before you install it. Itll be that much harder to wrangle a mature tomato plant into a cage than to just have it in place early.

How To Grow Tomatoes With A Hydroponic Deep Water Culture Method
When it comes to the recommended hydroponic systems for growing tomatoes, youll see DWC or Deep Water Culture, also see our article Our Picks for the 5 Hydroponic Bucket Systems and the 5 Grow Tent Kits with Buyers Guides.
DWC its an active system where nutrients are pumped through the system. It has much space for large sizes of tomato plants. Its a budget-friendly option, good for beginners. On the other hand, you have less control over individual plant care, and its most likely to be affected by root rot and pests. All you have to do is place the plant in a net pot found in the reservoir with the roots fully put in the water. The air pump will oxygenate the water to provide roots with the right amounts of oxygen.

Patio Hybrid Tomatoes In The Vegetable Garden
Especially if you have less space, bush-type tomatoes are easy to manage with their compressed vines that reach 2-3 tall.
These fast-maturing patio tomatoes bloom as a determinate crop and prefer a container at least 12 deep, as they develop 3-4 oz sweet, juicy and rich fruit.
As this bush-type variety only reaches 2-3 tall, you may not need to use a trellis, however, more support would help its compressed vines and upright growth. As these rich and sweet 3-4 oz tomatoes are fast-maturing, feed plants a liquid fertilizer a few times throughout development. Patio Hybrid Tomato seeds bloom an early-to-mid season determinate crop.
These patio tomato plants are perfect for containers, but will need more water than garden tomatoes.
Dutch Bucket Hydroponic Tomatoes
Bato/Dutch bucket is a system where 2 or more growing containers are linked to the same irrigation and drainage. You have a reservoir with mixed water and nutrients, which will feed every bucket in your whole system. A pump will send water up to an irrigation line. Once the water flows out of the line, the nutrients will start feeding the buckets. There are no limits in the number of buckets you can have 2 or even 100 of them. Then, such a system has a timer to run the pump from time to time. The main benefit of its that the whole system can be run unattended by you for a couple of weeks prior to changing the water.

How To Grow Tomatoes Outdoors
Do you need a greenhouse to grow tomatoes? This is one of the most common questions I get from my readers. I grow tomatoes outdoors without any issues. Why not give it a try?
It seems to be a given that tomatoes are always grown in the greenhouse. But thats not necessarily true. Some kinds are indeed supposed to be better suited for greenhouses though: For example the expensive F1 hybrids that are developed for greenhouse cultivation. But in most other cases, I think its a sliding scale. Adopting this frame of mind gives me the courage to experiment, and I think you should do that too. Its not as hard as you might think to grow tomatoes outdoors.
The pros of growing tomatoes outdoors
Im in no way an expert in growing tomatoes, but I manage to grow them with exactly the right of amount of success to cover my needs. I actually think its easier to grow tomatoes outdoors. They dont need as much supervision out in the open as in the polytunnel. The tomatoes grow super quickly in my polytunnel and require plenty time for watering, fertilization, tying and much more. Its a different pace outside. I also like adding some tall tomato plants to my outside areas in the kitchen garden.
There are a lot of not fully developed tomatoes to deal with in late fall. Most of them will ripen indoors and you can harvest them from large trays even in winter.
This is how I grow tomatoes outdoors:

How To Grow Patio Tomatoes
Start as with any other tomato, under heat and move up to a 3 pot. If the weather is against you, still cold, you may need to move it up a pot size before planting out. See the article on Sowing and Starting off Tomatoes
If you have a greenhouse or a coldframe then you can plant up in your container and keep it sheltered and warm until the weather is right to move it outside. Remember it isnt just frost to avoid but cold nights. See Ideal Temperature for Tomato Growing
Initially bring out in the day and return to cover at night for week to harden the plant off a little and avoid shocking it. If the weather turns cold after theyve gone out, horticultural fleece blankets can often save the day.
Dont forget that it is often warmer nearer the walls of a house or in an area sheltered from the wind. Just a degree or two can make all the difference.
The biggest problem with growing tomatoes in relatively small containers is the compost drying out and causing problems like blossom end rot and split skins. Always use a good quality compost that will help hold water and add water retaining crystals to the compost. These are generally available and just swell up when they meet water to release as things dry. They help ensure there is always moisture available in the compost.
With hanging baskets, line the interior with an old plastic bag with a few small holes punched through to help hold the water and rehydrate dried compost.
What Is An Earthbox
The EarthBox® Gardening System is planter with a built-in irrigation system. Marketed as a container garden for fruits, vegetables, and herbs, it has an aeration system and a water reservoir that allow it to self-water.
Normally, this supply of water, fertilizer, and dolomite should provide all the calcium the plants need, but in an EarthBox, blossom end rot is probably caused by unusually rapid growththe plant can’t take in enough calcium quickly enough. For those who experience blossom end rot in an EarthBox, mix 1/4 cup of lime with one gallon of water, and pour it into the reservoir. Do this only onceit should fix the problem.

Harvesting Tomatoes From The Garden
Tomatoes ripen best on the vine. Leave the fruit on the plant as long as possible. That being said, pick up any tomatoes that fall off before they ripen and bring them indoors to let them ripen up.
Dont worry growing tomatoes is like raising children: Perfection on your part is simply not possible. Youre going to screw up, but theyll probably be just fine anyway as long as you tried your best.

How To Plant A Tomato In A Container
Tomato plants grow quite well in containers as long as the container is large enough, has drainage holes, and is watered frequently.
Plant one seedling in each container. Use a quality potting mix made of peat moss/coconut coir and perlite. Add some nutrients to the potting soil by adding compost. Avoid using plain garden soil in a container garden if possible. Place the pot in a sunny area thats getting at least 6 hours of full sun daily. Plants in super-sunny southern areas may benefit from a bit of afternoon shade in the hottest months.
Container tomatoes dry out much more quickly than plants in the ground. Use a drip irrigation system to water them and be sure to check them every day.

Heirloom Vs Hybrid Tomatoes
Traditionally, nearly all grocery store tomatoes and most garden-grown tomatoes are hybridscarefully developed varieties that seek to maximize color and shelf-life, sometimes at the expense of unique taste and colors. Increasingly popular though, are so-called heirloom tomatoes, sometimes considered organic tomatoes. These are typically either original species or cultivars immediately descended from those species. They may have unusual shapes and colors, and often have a unique taste than store-bought tomatoes. The cost of growing these tomatoes is a plant that may be more susceptible to some common tomato pests and diseases.
Heirloom tomatoes once were the territory of gardeners willing to grow tomatoes from seeds, but many garden centers now offer a variety of heirloom plants along with their hybrid tomatoes.

Getting Your Tomato Plants To Set Tomatoes
The Spruce / K. Dave
Tomatoes’ ripening is pretty much at the mercy of the weather, but sometimes we can help things along. Pinching off the tips of the main stems in early summer will encourage indeterminate tomatoes to start putting their energy into flowering.
Indeterminate tomatoes like to grow tall before they start setting fruits, so don’t be alarmed if your tomato plants aren’t flowering for their first month or two. Pinching is also a handy trick toward the end of the summer when you want the last tomatoes to hurry up and ripen.
It shouldn’t be a problem getting determinatetomatoes to set fruit unless weather conditions are unfavorable and cause a condition aptly named “blossom drop.”

Mulching Tomato Plants In The Garden
The soil around your tomato plants should be mulched one the soil has had a chance to fully warm up. I like to mulch my tomatoes about a month after planting them outside. I mulch mine with more homemade compost, which helps keep moisture in the soil and discourage weeds from growing. The compost is also less likely to splash up onto the foliage during a rainstorm.
Compost used as a mulch prevents weeds just as well as shredded bark or wood chips , provides all the foods our growing plants need, and prevents disease spores from breeding on the surface of the soil .

Advice by Topic Container and Small Space Gardening Tomatoes
Enthusiastic gardeners know the story well: the garden is completely planted but wouldnt it be nice to grow just another tomato variety or two? You always have room for another when you plant those last few tomatoes in pots.
Tomatoes thrive in pots, and youre giving them just the conditions they need when you plant them in early summer. Warm days, warm nights, and warm soil stimulate growth. Small tomato plants set out in pots at the beginning of the summer will grow quickly and produce prodigiously.
All kinds of tomatoes are appropriate for pots, as long as the pots are of good size. Kansas City master gardener Kathy Hoggard recommends pots at least 20 inches across the top and 24 inches deep for tomatoes. Plastic pots are fine, Hoggard says: terra-cotta pots are beautiful but lose moisture through the clays pore pots made of plastic will not dry out as quickly as clay.
Find a spot that receives 6-8 hours of sun a day. Morning sun is better than afternoon sun, Hoggard says, but, in mild areas, sun in the afternoon is not as brutal as it is in the midwest. Good air circulation is important, but choose a place protected from high winds. Protecting plants from the wind also helps keep them from drying out.
Potting mixes drain well and retain moisture. Hoggard likes to mix compost into purchased potting mix, to add nutrients, and, for a further boost, she adds organic fertilizer when she plants.
