There’s no shortage of tomato-growing myths out there, but if you stick to these proven basics, you can grow everything from cherry to beefsteak—heirlooms or hybrids—whether in patio containers or garden beds.

If you are growing tomato vines that get really tall or produce large fruit, we’ve got you covered with a tutorial on how to build a wooden tomato cage.

1Know Which Type You’re Growing

It is very helpful to know which basic type of plant you are growing—a bush type (determinate), or vine type (indeterminate), so you are prepared to provide the right support (stakes, cages), and care including pruning through the growing season. This guide explains the differences.

2Plan Before You Plant

These ten tips before planting tomatoes will let you avoid some common mistakes tomato growers regret. Plan now, then plant.

3Get Supports Ready

If you are growing tomato vines that get tall or bushy with long stems, you’ll need support to prevent breakage. Once the fruit starts forming, it’s a lot of weight on those shoots!

4Learn When or If to Prune

There is a lot of contradictory information about pruning tomatoes and removing “suckers.” Ultimately, you want to prune if it helps the plant produce more fruit for you! If I can give you one mantra about pruning it is always prune for a specific reason, not just because you think you should. Some gardeners never prune their tomatoes, others are snipping and clipping every other day. You will learn when it’s warranted as you grow.

This has the basics on pruning tomatoes and sucker removal.

5Plan Ahead to Save Seeds

There are many different ways to save tomato seeds.

Tomato seeds have a protective coating on them which (smartly) prevents them from germinating or rotting inside the fruit.

This easy method for saving tomato seeds removes that coating through simple fermenting.

Frequently Asked Questions

Are tomatoes easy to grow?

I give tomatoes a 6 out of 10 for ease of growing. Some people think they have incredible growing skills or tricks but (sorry) it’s really just that the basic growing needs were met. And, sometimes, that the unnecessary extras didn’t interfere.

If you buy a small tomato plant in a basket, provide a sunny location, and keep up with the watering, it will probably be as easy as can be.

If you have one of those summers with a lot of rain and humidity, you might encounter tomato blight, blossom end rot, or other problems, which is a total drag.

Some gardeners also have relentless problems with critters eating their plants.

That said, if you’ve covered all the basics (right location, soil, care), provide support (cages or stakes), and prune smartly, sure it’s easy. And very rewarding.

Do you have any tomato growing secrets?

The secret is there are no secrets. Just focus on providing the right growing conditions.

Tomatoes love sun, most need support (cages or stakes) unless they are small, bush tomatoes, and fertile, well-draining soil is key. This shows how to test your soil drainage.

You can enrich your soil with good compost and also use a slow-release, organic fertilizer in containers as needed.

Watch out for the misinformation that is all over the internet where they tell you to add all sorts of weird additives to the soil.

Any tomato growing tips that claim a fast-track to success are completely misleading.

There is no evidence or scientific facts behind all the crazy claims involving Epsom salt, baking soda, sugar, coffee grounds, eggshells, and so on, as magical soil amendments when planting tomatoes.

Spare yourself the wasted time and energy and just stick to good gardening basics.

Can I grow tomatoes in pots?

Yes. I grow all my tomatoes in pots. Choose a container that is at least 12-inches wide and 12-inches deep (bigger is better) with drainage holes and use organic potting mix made specifically for growing vegetables.

Add support stakes or cages at planting time, otherwise you may damage the plant when trying to add them later.

Start with new organic potting mix each year because tomatoes are heavy feeders.

Can I grow tomatoes indoors?

You can grow tomatoes indoors but not easily. If you’ve seen commercial greenhouses that grow tomatoes, it’s a controlled setting with very specific growing conditions which are not easy to replicate in your home.

That said, I have had limited success just trying it for fun. A few times my bush tomatoes (determinates) have fruited indoors and I have grown a giant beefsteak tomato in front of a window—but I just got one.

Can you grow tomatoes from slices?

Yes. It’s not the most efficient way but it can work. You can grow tomatoes from slices or just by leaving a whole tomato out to rot in the garden if the seeds are viable and conditions are right. That’s how it happens in nature although controlled methods are more efficient.

Keep in mind that the seed type will determine what grows: heirlooms and other open-pollinated seeds will grow plants like their parents (unless cross-pollinated). Hybrid seeds may not produce anything like their parents (but I still grow them for the surprise factor). This explains the basic differences between these types of seeds.

That said, you can bury a slice of tomato in the ground and some tomato seedlings may sprout and grow. The problem is, because tomatoes are sun-lovers, they grow at during the warmest months of the year, so most of us start our seeds indoors or buy ready-to-plant plants to get a jump start on the season. Seeds germinating from slices may take a long time to sprout, and by the time they are growing in to plants, the warm season may be over.

Could you grow tomatoes from slices indoors? Yes, but same thing. It may be very slow. But, as a fun experiment, I say, go for it.

Every year I toss a bunch of end-of-season tomatoes right back into my garden beds and some of them always sprout and grow plants the next year.

Do marigolds help protect tomatoes from pests?

It doesn’t seem to be the magic answer that some gardeners imply. Also, prevention is hard to prove. There isn’t much research and testimonials are anecdotal.

Why do tomatoes split open on the vine?

Certain types of tomatoes are particularly susceptible to splitting open on the vine. This tends to happen after a prolonged hot and dry spell followed by a heavy rain. The fruits literally burst open, unable to hold the additional water within the fruit. This explains cracked tomatoes and answers whether they are edible and how the problem can be prevented.
