Growing Tomatoes in 5-Gallon Buckets – The Ultimate Guide

Growing Tomatoes in 5-Gallon Buckets – The Ultimate Guide

Hello there! Are you interested in growing your delicious, juicy tomatoes but don’t have a lot of space in your garden?

In This Article

Well, I have some fantastic news for you! You can easily grow tomatoes in 5-gallon buckets, a popular method among urban gardeners. The best part is you don’t need fancy equipment to start.

In this ultimate guide, I’ll walk you through the entire process, from choosing the perfect bucket to harvesting your yummy tomatoes. So, let’s dive in and learn how to grow the best tomatoes ever!

Selecting the Right Bucket

1. Why Choosing the Right Container is Important?

Before we start, picking the right container for your tomato plants is crucial. You see, tomatoes are pretty hungry plants and need many nutrients to grow big and strong. They also need plenty of room for their roots to spread out and enough space for nutrient-rich soil.

If you choose a container that’s too small, your tomato plants might not grow as well as they could, and you might end up with smaller, less tasty tomatoes.

On the other hand, if you pick a container that’s too big, you might accidentally give your plants too much water, which can make the soil too soggy and slow down their growth.

2. The Benefits of Using 5-Gallon Buckets

You might be wondering, “Why should I use 5-gallon buckets to grow my tomatoes?” Well, there are quite a few reasons!

  1. First, these buckets are the perfect size for tomato plants to grow comfortably. They’re big enough to fit at least two tomato plants, which means you can grow more tomatoes in a smaller space, like a balcony or a tiny garden.
  2. Another great thing about 5-gallon buckets is that they’re made from tough materials like plastic or metal to last for several growing seasons.
  3. Plus, they’re lightweight and easy to move around, which is helpful if you need to shift your plants to a sunnier spot or protect them from bad weather.

3. Types of Buckets

When you’re out shopping for your 5-gallon buckets, you’ll notice there are a few different types to choose from. The most common ones are plastic, metal, and fabric buckets.

Plastic buckets, especially those used at plant nurseries, are a popular choice for growing tomatoes. They’re lightweight, affordable, and come in fun colours. Remember that plastic buckets might not be as sturdy as metal ones and could crack or break over time.

Metal buckets, on the other hand, are built to last. They’re more expensive than plastic, but they’re also heavier and provide good insulation for your plants’ roots in colder weather. However, they might be a bit trickier to move around compared to plastic buckets.

Fabric grow bags are a newer option that many gardeners are starting to love. These bags are lightweight and allow for better airflow and drainage than plastic or metal buckets. The only downside is that they might rip or tear after a while.

4. Tips for Sourcing Buckets

So, where can you find these 5-gallon buckets? Here are a few ideas:

Hardware stores: Places like Home Depot or Lowes often carry 5-gallon buckets of various materials.
Restaurant supply stores usually have food-grade 5-gallon buckets perfect for growing tomatoes.
Online retailers: You can find a wide variety of 5-gallon buckets on websites like Amazon or eBay.
Local farms or businesses: Check with nearby farms or companies to see if they have any extra buckets they can sell or give you.

Preparing the Bucket for Planting

1. Importance of Drainage Holes and Proper Spacing

Now that you’ve got your perfect 5-gallon bucket, it’s time to get it ready for planting!

One of the most important things to do is ensure your bucket has enough drainage holes. These holes allow extra water to flow from the bucket, so your tomato plants don’t sit in too much water and get sick.

It’s also important to space out these holes evenly to help with airflow and prevent overcrowding.

2. Creating Drainage Holes

You’ll need your 5-gallon bucket, a drill or hammer and nail, and some small rocks to make drainage holes. Start by making several small holes in the bottom of your bucket and spacing them out evenly. Then, put a few small stones at the bottom of the bucket.

These rocks will help keep the holes from getting clogged with soil. You can also add some landscaping fabric or mesh on top of the stones for extra protection.

3. Use High-Quality Potting Mix

When growing tomatoes in 5-gallon buckets, it’s important to use a high-quality potting mix. This special mix has all the nutrients your plants need to grow strong and healthy, and it also helps their roots grow properly.

Don’t use regular garden soil or topsoil because it can get too packed down in the bucket, making it hard for your plant’s roots to grow.

4. Tips for Choosing a Potting Mix

When picking out a potting mix, look for one made specifically for containers or vegetables. These mixes are lightweight, drain well, and have important nutrients like nitrogen, phosphorus, and potassium.

Avoid mixes that already have fertilizers or pesticides mixed in because they might be too strong for your young tomato plants.

Best Tomatoes to Grow in 5 Gallon Buckets

a. Ideal Tomato Varieties for Container Gardening

When growing tomatoes in 5-gallon buckets, choosing the right type of tomato plant is important.

Not all tomato varieties will grow well in containers because some might need more space or support than others.

The best tomato varieties for container gardening are usually compact and have a shorter growing season. This is because 5-gallon buckets have limited space and don’t have as much room for roots or nutrients as an in-ground garden.

Plus, container tomatoes need to be able to hold up their fruit without falling over.

b. Best Tomatoes for 5-Gallon Buckets

Here are some of the best tomato varieties for growing in 5-gallon buckets:

  • Cherry Tomatoes: These tiny tomatoes are perfect for snacking and can give you a big harvest in a small space. They also have a shorter growing season, which makes them great for container gardening.
  • Patio Tomatoes: These varieties are specially bred to grow on patios or in containers. They’re compact and produce lots of medium-sized tomatoes.
  • Determinate Bush Varieties: These tomatoes are bred shorter and bushier, making them perfect for container gardening. They also produce their harvest earlier and all at once.
  • Dwarf Varieties: These tiny tomato plants are ideal for small containers and have a short growing season. They also come in different shapes, sizes, and colours.

3. Determinate vs. Indeterminate Varieties

When choosing a tomato variety for container gardening, knowing the difference between determinate and indeterminate varieties is important.

Determinate varieties are smaller and have a shorter lifespan. They stop growing once they reach a certain height and produce all their fruit at the same time. This makes them perfect for container gardening because they don’t need much space and are easier to care for.

Indeterminate varieties, on the other hand, keep growing and producing fruit throughout the entire growing season. They need more vertical space and support for their vines, which might not work well for container gardening.

d. Factors to Consider when Choosing the Tomato Variety

When you’re picking the perfect tomato variety for your container garden, there are a few things to think about:

  • Space: As we talked about earlier, determinate varieties are better for smaller spaces and containers. If you don’t have a lot of room, choose a variety that won’t outgrow its container.
  • Climate: Some tomato varieties do better in certain climates. Think about the average temperature and humidity where you live, and make sure the tomato variety you choose will do well in those conditions.
  • Type of container: The size and type of container you use can also affect how well your tomato plants grow and produce fruit. Choose a container with good drainage and enough room for the roots to grow.
  • Personal preference: Finally, think about what kind of tomatoes you like best! Do you prefer big, juicy slicers or small, sweet cherry tomatoes? Choose a variety that fits your taste preferences.

Choosing the Right Time to Plant

When it comes to planting your tomatoes in 5-gallon buckets, timing is everything! You’ll want to wait until the last frost has passed in your area and the soil is nice and warm. This will help your tomato seeds or seedlings grow strong and healthy.

How to Grow Tomatoes in a 5-Gallon Bucket?

If you live somewhere with chilly weather, you can start your tomato seeds indoors and then move them to their buckets once it’s warm enough outside. This way, they’ll have a head start on growing!

How to Plant Tomatoes in a 5-Gallon Bucket?

You can plant your tomatoes in buckets in two main ways – using seedlings or growing them from seeds.

If you decide to use seedlings, wait until they’re about 6-8 inches tall before moving them to their permanent home in the bucket. This gives them enough time to develop strong roots.

If you want to grow your tomatoes from seeds, you can plant them right in the bucket! Fill your bucket about three-quarters full with good quality potting soil, then place your seeds on top and gently press them into the soil.

Cover them with a thin layer of soil and give them a good watering.

Proper Spacing and Depth for Planting

When growing tomatoes in 5-gallon buckets, giving them enough room to grow is important.

One plant per bucket should be plenty for determinate varieties (the ones that grow to a certain height and then stop).

But for indeterminate varieties (the ones that keep growing and making fruit until the first frost), you might need a bigger bucket or fewer plants in each one.

As for how deep to plant them, make sure you put your tomato plants deep enough so the bottom set of leaves is just above the soil. This helps them develop a strong root system and keeps the plant stable as it grows.

If your seedlings are tall and skinny, you can bury them deeper than usual, leaving just the top few leaves above the ground.

Caring for Your Tomato Plants


Watering your tomato plants the right way is super important for keeping them healthy.

Tomatoes need at least one inch of water each week, and when they’re growing in 5-gallon buckets, you might need to water them more often.

Sticking your finger into the soil up to your knuckle is an easy way to check if your plants need water. If it feels dry, it’s time to give them a drink!

When you water your tomatoes in their 5-gallon buckets, make sure to water them deeply and evenly. This means watering the whole surface of the soil until it’s damp, but not soaking wet.

Try not to get the leaves wet because this can sometimes cause fungal diseases.


Tomatoes are big eaters and need regular fertilizing to grow their best. When growing them in 5-gallon buckets, they can only get nutrients from the soil in their container, so it’s extra important to use a high-quality potting mix.

Feed your bucket of tomatoes every two weeks with a balanced fertilizer (like a 10-10-10) or an organic option like compost or fish emulsion.

Just be careful not to over-fertilize, because this can make your plants grow lots of leaves but not many fruits. Always read the instructions on your fertilizer package to know how much to use.


Mulching is a part of container gardening that people sometimes forget about, but it’s actually really helpful! Putting a layer of mulch around your tomato plants can help keep the soil temperature steady, retain moisture, and stop weeds from growing.

You can use an organic mulch like straw or shredded leaves around the base of your tomato plants. This can also help keep soil from splashing onto the leaves when you water, which can sometimes lead to fungal diseases.

Staking or Caging

Tomato plants are known for growing big and producing lots of heavy fruits. If they don’t have enough support, they can get wild and even break under the weight of their tomatoes.

To stop this from happening when you’re growing tomatoes in 5-gallon buckets, you should stake or cage them. This gives them something to lean on and helps airflow around the plant.

Pest and Disease Management:

Keep a close eye on your tomato plants and check them regularly for signs of pests like aphids, whiteflies, or hornworms.

If you spot any unwanted critters, you can pick them off by hand or use an organic pest control method to eliminate them.

Fungal diseases are also common when growing in containers because the humidity can be higher. Ensure your plants have good airflow, and be careful not to overwater them.

If you notice any leaves or fruits that look diseased, remove them immediately and throw them out somewhere far from your tomato plants.

You can also use an organic fungicide to help stop the disease from spreading. Always clean your containers and tools well, and sanitize them with bleach before using them again.

Pruning and Training

How to Prune and Train Tomato Plant in a 5-Gallon Bucket?

Start by taking off any suckers that are growing where two branches meet. These little shoots can steal energy from the main stem, so removing them regularly is best.

Next, look for any branches that are growing down towards the ground or the middle of the plant. These branches won’t get enough sunlight, so you should prune them off.

Also, remove any yellow or damaged leaves because they can be a breeding ground for diseases and pests.

Use something soft like twine or plant ties to tie the main stem to a stake or trellis gently. This will help hold up the weight of the plant and keep it from falling over. As your plant keeps growing, keep removing suckers and pruning off any branches you don’t need.

Aim for one main stem with 4-5 healthy side branches. Use plant ties or tomato clips to carefully train the remaining branches to grow up toward the light. This will help keep your plant from getting too bushy and let more sunlight and air reach all parts of the plant.

Benefits of Pruning and Training

  1. A tomato plant that’s well-pruned and trained doesn’t just look nicer – it can also grow better and produce more fruit. By removing extra branches and leaves, your plant will have better air circulation, which can help prevent diseases like fungal infections.
  2. Pruning and training also let your plant focus its energy on growing fruit instead of growing extra branches and leaves it doesn’t need. When you train the branches to grow up towards the light, more of the plant can get sunlight, which means healthier plants and more tomatoes.
  3. A tomato plant that’s pruned well is also easier to pick tomatoes from because the fruits are easier to reach, and there aren’t as many extra branches and leaves in the way. By taking off any damaged or diseased leaves, you can help stop pests and diseases from spreading to the rest of your plant.

Container Garden Challenges and Solutions

1. Nutrient Deficiencies

Growing tomatoes in 5-gallon buckets can be tricky to ensure your plants have all the nutrients they need.

Unlike regular garden beds, containers only have a small amount of soil, and the nutrients in that soil can get used up quickly. This can cause your tomato plants to have nutrient deficiencies, which means they might not grow as well or produce as much fruit.

To stop this from happening, it’s important to fertilize your bucket of tomatoes regularly. Look for a high-quality fertilizer made just for tomatoes, and follow the directions on the package to know how much to use.

You can also add some organic stuff to the soil to give your plants extra nutrients, like compost or worm poop (it’s not as gross as it sounds, I promise!).

If you notice any signs that your tomato plants aren’t getting enough nutrients, like yellow leaves or slow growth, don’t wait – fertilize them right away and add some good stuff to the soil.

By keeping a close eye on your plants and giving them the nutrients they need, you can help them grow up to be strong and healthy, even in a 5-gallon bucket.

2. Root-Bound Plants

Another problem you might run into when growing tomatoes in 5-gallon buckets is “root-bound plants.”

This happens when your tomato plant’s roots get too big for the container and start getting all tangled up and squished together. When this happens, the roots can’t grow properly or get the nutrients they need, which can make your plant sick.

To stop your plants from getting root-bound, it’s important to choose a big enough container for your tomato plant’s roots to have plenty of room to grow.

A 5-gallon bucket is usually big enough for one tomato plant. You should also check on your plant’s roots occasionally, and if they start looking too crowded, move your plant to a bigger container.

If you notice that your tomato plant is starting to get root-bound, don’t worry – you can still help it! Carefully remove your plant from its container and gently loosen up the roots a bit, like you’re giving them a little massage.

Then, put your plant in a bigger container with fresh soil. This will give the roots more room to grow and help your plant stay healthy.

3. Overwatering

Overwatering is another thing that can cause problems when you’re growing tomatoes in 5-gallon buckets.

When it’s hot outside, it may be tempting to water your plants a lot, but this can hurt them more than it helps.

When the soil stays too wet all the time, it can cause the roots to rot and make your plant sick.

Instead of watering your tomato plants all the time, please wait until the top inch of soil feels dry before you water them again. This will help the roots grow strong and healthy, and it will stop your plants from getting too much water.

If you think you have overwatered your tomato plants, there are a few things you can do to help them.

First, stop watering them for a little while and let the soil dry. You can also add some small rocks or gravel to the bottom of your container before you add the soil – this will help the extra water drain out so your plant’s roots don’t sit in it.

Harvesting and Enjoying Your Tomatoes

1. Determining Ripeness

After all your hard work caring for your tomato plants, the most exciting part is finally picking your ripe tomatoes! But how do you know when they’re ready to be picked?

If you like them too early, they won’t be as sweet and yummy, but they might get too mushy if you wait too long. Here are some tips to help you tell when your tomatoes are perfectly ripe:

  • Colour: Different types of tomatoes can be different colours when they’re ripe, from light green to bright red. Look for a colour that’s even all over, with no green or white spots.
  • Squishiness: Gently squeeze your tomato – it should be a little bit soft but not too mushy. If it’s still really hard, it might need a few more days.
  • Size and shape: Check the label that came with your tomato seeds or plant to see how big and what shape your tomatoes should be when they’re ready.
  • Smell: Ripe tomatoes have a sweet, earthy aroma that makes your mouth water. If your tomato doesn’t smell like anything or smells sour, it’s not quite ready yet.

2. Harvesting Tips

When picking your ripe tomatoes, always use clean, sharp scissors or garden shears to cut them off the vine. This helps keep your plant from getting damaged.

Don’t pull or twist the tomatoes off the vine because this can hurt the tomato and the plant. Try to pick your tomatoes in the morning when they’re nice and cool and full of water.

If you’re growing a type of tomato plant that keeps making more tomatoes all season long (called an indeterminate variety), make sure to pick the ripe ones regularly. This will help your plant keep growing and make more yummy tomatoes to enjoy!

3. Enjoying Your Harvest

Now that you’ve got all these delicious homegrown tomatoes, what should you do with them? Here are a few tasty ideas:

  • Tomato Jam: Want to try something a little different and sweet? Make your tomato jam! Cook down your ripe tomatoes with sugar, spices, and lemon juice until it’s thick and spreadable. It’s super yummy on toast or as a topping for meat and cheese.
  • Tomato Juice: If you have many extra tomatoes, blend them with water, lemon juice, and a pinch of salt to make your fresh tomato juice. Pour it through a strainer to remove the seeds and pulp, then enjoy a refreshing drink.
  • Tomato Salad: Chop some of your tomatoes with cucumbers, onions, and feta cheese for a healthy and tasty salad. Drizzle olive oil and balsamic vinegar for a simple, delicious dressing.
