Grow bags are a great option for those who want to grow their own tomatoes! They’re easy to use, inexpensive, and save a lot of space.

I discuss why this is in the article and what factors affect the choice of your grow bags. I also list some useful tips when deciding on buying the best grow bags for your tomato plants.

What Size Grow Bag For Tomatoes You Should Get:

For determinate tomato plants use grow bags that are 10 gallons or larger in size. For indeterminate tomatoes, you will need a grow bag that is at least 20 gallons or larger. You can only use 5-7 gallon grow bags for tiny tomato varieties. 

The point I’m trying to make here is that your choice of grow bag depends quite a lot, on what variety of tomato you wish to plant. I would usually recommend going with a deep grow bag with plenty of room for growth. This way your plants won’t outgrow the bag prematurely and will produce more fruit.

What is A Grow Bag:

The grow bag is a specialized container designed primarily for growing plants and vegetables. It can be used both indoors and outdoors.

Why You Shouldn’t Use Small Grow Bags For Your Tomato Plants:

A small tomato plant in a small grow bag will struggle to develop a strong root system and this will limit the potential growth of that plant. It is better to choose a large enough grow bag so that there is plenty of room for the roots to develop.

You may also find that some varieties need more space than others – larger fruiting varieties like Beefsteak, for example, tend to need more room than smaller fruiting varieties like ‘Sweet Million’ cherry tomato plants.

You don’t have to worry about this if you use a large grow bag for your tomatoes.

Advantages of Grow bags:

You can use grow bags to grow almost anything, including herbs, flowers, fruits, and veggies. They don’t need a lot of space to get started and are easy to move around. Grow bags make it easy to customize your garden with change.

Foldable grow bags are very convenient for storing unused ones, or for transporting plants from one location to another.

You will also find some grow bags that have handles on the sides that allow you to carry them more easily. The handles make it easier to move the containers around your yard or garden and also make it easier for you to lift them into your vehicle for transporting your plants from one location to another during the growing season.

Is It Better To Grow Tomatoes In Pots Or Grow Bags?

Growing tomatoes in pots or grow bags is a matter of choice. You can use either option successfully if you know which one will work best for you.

When deciding whether to use a grow bag or grow container for tomatoes, there are many factors to consider. One of the biggest is how much space you have available. If you have only one or two plants growing at home, then you will likely have enough room to fit them comfortably in a container (or pots) without taking up too much space. 

However, if you plan on having more than one type of tomato plant growing at home, then grow bags are a better option as they provide enough room for all your plants to develop successfully. 

Tomato plants don’t require a lot of space. You can grow them in pots, raised beds, or even on your deck or in your backyard. If you have limited outdoor space and want to grow tomatoes, you’ll probably want to use grow bags.

Types Of Grow Bags For Tomato Plants:

As far as tomato plants go, the best material for the growth of your tomato plants is either fabric or plastic. Both materials will work well to keep your soil together and hold moisture, but each has its own advantages over the other. Cost-wise, fabric bags can be a little more expensive than plastic bags. 

How To Choose A Grow Bag For Growing Tomatoes:

There are several factors that determine what size grow bag is best for growing tomatoes. So, before you buy a bag, make sure you consider all of the variables.

Tomato Variety: 

The type of tomato you are growing will determine what size grow bag you should choose. Smaller tomato varieties like cherry or pear tomatoes require smaller bags, while larger tomato varieties such as beefsteak need larger bags to support their growth and produce more fruit. 

Also depending on whether you are growing a determinate variety or an indeterminate one your choice of grow bag will change.

Type of Soil: 

Ideally, you should use potting soil in your grow bag when planting tomatoes. But if you decide to use your garden soil, then a bigger bag can carry more soil to ensure your plants get as many nutrients as possible.

If using potting soil in your grow bags, then be sure to add some sand or perlite to improve drainage and aeration.

Growing Location:

Depending on whether you want to grow tomatoes indoor or outdoor your grow bag will differ as different locations can lead to different types of care and maintenance for your tomatoes.

Toxicity: Some people worry about the toxicity of plastic materials used in grow bags and containers. If you’re concerned about plastic toxicity, you may want to go for fabric grow bags.


The portability of the plants can also be deciding factor for choosing your grow bags. If you move your tomato plant rather frequently, grow bags with handles can be a good option for you.

How To Plant Tomatoes In Grow Bags:

If you are going to use grow bags for growing tomatoes, it is important to choose the correct bags. My personal favorites are fabric grow bags.

You can also buy plastic grow bags, if you are looking for cheaper options.

Once you have selected the grow bags, first, make sure it has a drainage hole at the bottom. This is essential for growing any plant and not just tomatoes.

Now, fill the container half-full with a quality potting mix and tuck your tomato seedling into its cozy new home. Add a bit of water to make the soil moist.

Tomatoes need a lot of space to grow roots, so plant them a bit deeper than other plants. For seeds, sow them when the bag is 3/4th full.

After that fill the rest of the bag with potting mix, and finally, place your grow bag in an area that receives plenty of sunlight.

Tips For Growing Tomatoes In Grow Bags:

Tomatoes need plenty of sunlight to produce bountiful amounts of fruit. You can place the grow bag in a sunny, bright, and well-ventilated area. if you have a south-facing window put the bag near the window so it gets plenty of sunlight.

Grow bags (fabric ones in particular) tend to lose water very quickly through evaporation, so water them frequently. You don’t want your tomatoes to die out of thirst.

Plant your tomatoes deep. it will encourage more root growth and also prevents the plants from toppling over.

Tomatoes are voracious feeders, so make sure your grow bag is full of plant nutrients. Use compost, organic fertilizers to keep the soil enriched. Adding crushed eggshells or coffee grounds will also benefit your tomato plant.

Try out different tomato varieties and see which one does best for you. You can lots of tomato growing tips in this post, so do check that out.

Tomatoes are top-heavy. So tie them up with something like balcony rails so they won’t get blown away in wind or storms. this is especially true for growing tomatoes in grow bags.


Tomato plants produce quite a lot of fruit and the grow bag needs to be deep enough to accommodate those plants. Get a deep grow bag so that your plants can grow without any kind of complications whatsoever.

I hope that this article has helped to steer you in the right direction. Remember, shop wisely and select a nice deep bag with plenty of room for your tomatoes to grow upward in.
