Have you ever dreamed of growing your own tomatoes, beans, cucumbers, carrots, onions, and flavorful garlic without having to dig a garden in your yard? In this post, you’ll discover why 10 gallon grow bags are the perfect size for your container vegetable garden.

Well, guess what?

You can grow all of these common vegetables right in your backyard or even on your back patio using 10 gallon grow bags!

You might be wondering, “What’s a grow bag?” It’s like a big, sturdy fabric bag made just for plants or growing vegetables.

You fill it with soil, plant your seeds or small plants, and watch them grow!

In my experience, 10-gallon grow bags are the perfect-sized grow bags for gardening.

They’re easy to move around, they let your plant’s roots breathe (which they love!), and they make sure your plants don’t get too much or too little water.

Smaller bags dry out too fast, and larger bags are too heavy to move, but 10-gallon bags are JUST RIGHT!

In this fun guide, we’re going to explore how these awesome 10-gallon grow bags can be the perfect home for some of your favorite vegetable crops in any size garden you want to grow.

We’ll talk about how many of each vegetable you can plant in one bag and how to take care of them.

We’ll also cover the plants per person that you’ll need for each crop.

You can never have too many delicious veggies, and growing in these containers allows you to expand your garden without having to set up raised beds or eat into your growing season by having to dig an in-ground garden.

So, grab your gardening gloves, and let’s dive into the world of grow bag gardening.

You’re about to become a grow bag gardening superstar.

Why 10 Gallon Grow Bags are Ideal for Container Gardening

Let’s talk about why 10 gallon grow bags are the perfect size for your container vegetable garden

Imagine having a little garden that you can move around easily – that’s what these grow bags offer!

First off, these bags are amazing space-savers. Whether you have a tiny balcony or a big backyard, you can fit these bags just about anywhere. They’re portable gardens! Plus, the size is just right – not too big, not too small. You know, like the Goldilocks of grow bags!

Now, let’s talk dirt – literally! Soil health is super important for your plants, and these 10 gallon bags are champs at keeping the soil healthy. Good soil is a must, so fill your bags with compost, potting soil, or composted leaf mulch to provide plenty of nutrients.

They allow air to flow through, which means the roots of your plants get to breathe (yes, roots breathe too!).

Your plants roots will also air prune, which means that when the roots reach the edge of the container, they stop growing and the plant sends out another root from the main stem. This gives a more bushy root ball with healthier roots, and keeps your plants from getting root bound.

Another cool thing about the 10 gallon size of these bags is how they hold onto moisture better than a smaller bag. They can hold a mass of soil that is big enough to keep the plants roots moist, but not too moist. With ten gallon grow bags, you can get by with watering once per day, but if you have smaller bags, you’ll have to water more frequently.

Compared to a traditional garden or raised beds, grow bags are way easier to manage. No more bending over too much or dealing with pesky weeds. It’s gardening made simple and fun!

Now, why not smaller or bigger bags? Well, 5 gallon bags are like tiny apartments for plants – they get cramped and dry out too fast. And 20 gallon bags? A 20-gallon bag is a large container that is almost impossible to move once it’s full of soil and plants. The 10 gallon size is just perfect – like a cozy house with a yard for your plants.

Growing Tasty Tomatoes in 10 Gallon Grow Bags

Alright tomato lovers, let’s talk about growing these red (or yellow, or purple!) beauties in 10 gallon grow bags. It’s like having a tiny tomato farm right in your own space!

How Many Tomato Plants per Bag? First things first, how many tomato plants can you fit in a 10 gallon grow bag? The magic number is one. Yep, just one tomato plant per bag. This might seem like a solo act, but trust me, giving each plant its own space is key to a bountiful harvest.

Choosing the Right Tomato Types Now, what types of tomatoes work best in these bags? You’ve got a bunch of choices! Cherry tomatoes are a fantastic pick – they’re like the snack-sized candies of the tomato world. If you are looking for cherry tomatoes to grow, check out Sungold and Sweet 100. They are my favorites right now.

But don’t stop there; you can also try growing beefsteak, Roma, or heirloom varieties. Each type has its own unique flavor and use, so feel free to experiment in your garden space.

Tips for Healthy Tomato Plants To keep your tomato plants happy and healthy in their grow bag homes, here are some top tips:

  1. Sunshine is Your Best Friend: Tomatoes love the sun – like, really love it. Make sure they get at least 6-8 hours of direct sunlight every day. It’s like their daily sunbath!
  2. Water Wisely: Keep the soil moist but not soggy. Tomatoes don’t like wet feet! A consistent watering schedule helps prevent issues like blossom end rot.
  3. Support System: As your tomato plants grow, they’ll need some support. Use cages or stakes to keep them upright and proud. It’s like giving them a little hug to help them stand tall.
  4. Pollination Power: For the best pollination, give your plants a gentle shake now and then. This helps spread the pollen around. You can also attract bees and other pollinators by planting flowers nearby. It’s like throwing a party for pollinators in your garden!
  5. Feed Them Right: Use a good quality fertilizer to give your tomatoes the nutrients they need. Think of it as their special tomato food.


Growing tomatoes in 10 gallon grow bags is a fun, rewarding experience. You get to watch your plants grow and eventually enjoy the fruits (or should I say tomatoes?) of your labor. So, grab a grow bag, plant a tomato, and get ready for a season of delicious, homegrown tomatoes!

Growing Green Beans in 10 Gallon Grow Bags

Hey bean enthusiasts! Ready to grow some crunchy, delicious beans in your 10 gallon grow bags? Let’s jump right in and turn those bags into a bean-growing haven!

How Many Beans Can You Squeeze in a Bag? When it comes to planting beans in a 10 gallon grow bag, you’ve got room for about 2 to 4 plants. Whether you’re growing beans, pole beans, or any other variety, this number gives each plant enough space to thrive without turning into a tangled mess.

As a rule of thumb, I recommend 2 bean plants per bag if you’re growing pole beans. You can fit up to 4 bean plants per bag if you’re growing bush beans.

How Many Beans Will Your Family Need? To grow enough beans for your family, plan on about 10-15 plants per person. This should give you a nice, steady crop throughout the growing season.

If you love beans and use them a lot, you might want to plant a few extra. So, just doing the quick math, if you need 15 plants per person, you’ll need 4 10-gallon grow bags per person.

Supporting Your Climbing Beans Now, if you’re growing pole beans, they’re like the climbers of the bean world – they love to reach for the sky! To help them along, you’ll need some support structures. Here are a couple of ideas:

  1. Bamboo Stakes: These are like the bean plant’s best friends. Stick a few bamboo stakes into your grow bag and tie them at the top to create a teepee shape. Your beans will happily climb up these.
  2. Trellis System: If you’re feeling a bit more adventurous, set up a trellis behind the grow bag. This gives your beans a fantastic ladder to climb as they grow.

For bush beans, you can relax a bit as they don’t need support – they’re the chill, low-maintenance type.

A Few Bean-Growing Tips

  • Sunshine Love: Beans adore the sun, so place your grow bags in a spot where they’ll get plenty of it.
  • Watering Wisdom: Keep the soil consistently moist. Beans aren’t fans of dry soil, but they also don’t like soggy feet. It’s all about balance.
  • Companion Planting: Consider planting some friendly neighbors like marigolds or nasturtiums in the same bag. They can help deter pests and make your bean plants even happier.

Growing beans in 10 gallon grow bags is a fun and rewarding experience. You’ll be amazed at how these little seeds transform into bountiful bean plants. Once you grow beans, you might branch out into peas as well.

Cucumber, Carrot, and Onion Cultivation

Cucumbers in Grow Bags

Cucumbers are a natural fit for growing in 10 gallon grow bags. I plant 2 seeds in each 10 gallon grow bag, and I try to grow bush varieties, like this Bushy variety from Seed Saver’s Exchange.

Bush varieties are much more compact in size, and can be grown easily in 10 gallon pots. When I’m growing bush cucumber varieties in 10 gallon bags, I plant 2 plants per bag and trellis them as they grow.

You can harvest up to 10 cucumbers per plant per season, so use that as your guideline to decide how many grow bags you want to devote to cucumbers. Each plant will yield 1-2 cukes per week during peak growing season.

Cucumbers can be succession planted, and they should be, because they can fall victim to powdery mildew pretty easily.

Succession planting is simply waiting a few weeks after you’ve planted a pot or two, and then planting some more that will mature later. These succession plantings mean that you will have ripe cucumbers for months and months!

Carrots in Grow Bags

Carrots are another crop that grow well in grow bags. Carrots need a long space to grow the root, and a 10 gallon grow bag has a space that’s almost a foot long they can grow into. It’s easy to harvest carrots from a grow bag as well, since the soil is usually quite loose.

How Many Carrots Should You Grow?

A good rule of thumb is about 10-15 carrot plants per person. They can be planted closely, so you can fit quite a few in a small space. Carrots are great because they can be enjoyed by fresh eating, or stored for winter use, ensuring you have a steady supply.

Carrots can be finicky to germinate. I’ve created a lot of YouTube videos that show my step-by-step carrot germination method, so check out those videos. I’ve added them below. They are quick and to the point. Watching them is a good use of your time, if I do say so myself!

Onions in Grow Bags

Onions–particularly green onions– do very well in grow bag gardening scenarios. They are fast-growing, and don’t need a ton of room, so you can grow ALOT of green onions in a single grow bag.

If you have 2 grow bags devoted to green onions, you could seed the first bag, then wait 3-4 weeks and start the second bag. This way, you’ll have a continuous harvest for MONTHS.

To plant green onions in your grow bags, simply purchase a variety you like, and plant the seeds about 1/4 of an inch deep and cover with soil. Water them in, and your all set.

I like these Tokyo Long White Bunching Onions, because they can be harvested small, or you can leave them in the ground and let them grow larger for an onion that is almost an inch in diameter.

Garlic Planting and Per Person Planting Guide

Let’s dive into the world of garlic planting and figure out how to plan your garden for a family-sized harvest!

In a 10 gallon grow bag, you can comfortably plant about 10-12 garlic plants. Garlic doesn’t need a ton of space, but it does like its personal area. Plant the cloves about 4-6 inches apart, and you’ll be on your way to a fragrant harvest!

On average, a person uses about 8-10 bulbs of garlic a year. So, for a family of four, aim for around 40 bulbs, which will be 4 10-gallon grow bags for your garlic. Remember, each clove you plant gives you one bulb!

 Drip Irrigation for Grow Bags

Watering your plants correctly is crucial, and drip irrigation is a fantastic way to make this task easier and more efficient, especially for your 10 gallon grow bags.

How Many Drip Emitters per Bag? For a 10 gallon grow bag, you’ll typically need 2-3 drip emitters. This setup ensures even water distribution, allowing the entire root system to access moisture. Place the emitters evenly around the plant to cover the soil area effectively.

The drip emitters I usually use deliver 1/2 gallon or 1 gallon of water per hour. You can try both sizes to see which ones work best for each grow bag in your conditions.

Benefits of Drip Irrigation


  1. Consistent Moisture Levels: Drip irrigation provides a steady supply of water directly to the roots, maintaining an ideal moisture level. This is especially beneficial during hot or dry periods when your vegetable garden can get thirsty quickly.
  2. Water Efficiency: This system reduces water waste significantly. By permeating the soil and delivering water directly to the plant roots, you avoid the evaporation that happens with traditional watering methods.
  3. Prevents Root Bound Issues: Consistent moisture helps roots grow strong and spread out, reducing the risk of them becoming root bound. This is particularly important in the confined space of a grow bag.
  4. Healthier Plants: Drip irrigation helps keep the foliage dry, which is crucial in preventing diseases that thrive in wet conditions. Your plants stay healthier and happier.
  5. Time-Saving and Convenient: Once set up, the system takes care of the watering for you. This means less time with the hose and more time enjoying your vegetable garden.
  6. Adjustable to Plant Needs: You can easily adjust the flow of water to meet the specific needs of different plants, ensuring that each one gets just the right amount of water.

Incorporating drip irrigation into your containers is a smart move. It simplifies your gardening routine, conserves water, and promotes the growth of robust, healthy plants.

Additional Tips for Grow Bag Gardening

  1. Choosing Potting Soil: Opt for high-quality potting soil that’s well-draining and nutrient-rich. Avoid using garden soil as it can be too heavy and may contain pests.
  2. Managing Pests: Keep an eye out for common pests. Use natural deterrents like neem oil or insecticidal soap. Encourage beneficial insects by planting flowers nearby.
  3. Sunlight Exposure: Most vegetables need 6-8 hours of direct sunlight daily. Position your grow bags in a sunny spot, but be ready to provide some shade during the hottest part of the day to prevent overheating.
  4. Extend Your Growing Season: You can extend your growing season by moving these grow bags into a warm, sheltered area after your first frost. You can grow vegetable plants well into winter by doing this. Your plants will thinks it’s still summer, and you can’t do that with an in-ground garden, or a raised bed garden!
