How to Grow Tomatoes in Pots? Growing tomatoes is a rewarding and satisfying experience, but not everyone has access to a garden. Luckily, you can still grow these delicious fruits on your balcony, patio, or even inside your home by using pots.

Growing tomatoes in pots is an excellent solution for urban gardeners or those with limited space. In this post, we will discuss everything you need to know to successfully grow tomatoes in pots, from choosing the right container to harvesting your first crop.

Growing tomatoes in pots is a good way to get the most out of a home garden. They are easy to grow, and you can grow them anywhere, indoors or outdoors in a sunny spot.

However, it is important to choose the right variety for your needs. Some tomato varieties can suffer from blight, which is a fungal disease that causes the leaves and stems to die and the fruits to rot.

Thankfully, there are a number of blight-resistant tomato varieties that will produce good fruit even in wet, warm weather, such as Beaverlodge, Glacier and the ‘Sakura‘ variety.

These blight-resistant tomatoes can also be grown in hanging baskets and are ideal for balconies and patios.

Generally though, look for compact, determinate (size-conditioned) varieties that won’t grow too tall or wide, such as Patio, Bush Early Girl, or Celebrity. These varieties are well-suited to container gardening and will produce a good yield of delicious tomatoes.

Choosing The Right Container

When it comes to growing tomatoes in pots, the size and material of the container are crucial. Tomatoes require a lot of room for their roots to grow, so it’s essential to choose a container that is at least 20in deep (50cm) x 18in (45cm) wide for determinate (Determinate tomatoes are varieties that grow to a fixed mature size and ripen all their fruit in a short amount of time) tomatoes.

For indeterminate (Indeterminate tomato varieties will continue to grow and ripen fruit throughout the growing season) tomatoes a 24-inch (60cm) wide pot should suffice. This will ensure that your tomato plant has plenty of space to grow and produce fruit.

In terms of material, plastic or ceramic pots are popular choices as they are lightweight and easy to move around. However, terracotta pots are also a great option as they are ‘breathable’ and can help regulate soil moisture levels. Whichever material you choose, make sure the pot has drainage holes to prevent waterlogging, which can lead to root rot.

Selecting the Right Soil

Once you have your correct-sized pot, it’s essential to ‘prepare’ it properly. Start by filling the bottom of the pot with rocks or stones to help with drainage. I also suggest you wash/clean the rocks and stones thoroughly though, to avoid any cross-contamination/transmission of disease into your potting soil.

To grow healthy tomatoes in pots, you need to select the right soil. A good-quality potting mix will ensure that your plants have the nutrients they need to thrive.

Look for a mix that is well-draining and specifically formulated for container gardening. It should be a blend of peat moss, vermiculite, and perlite, with added nutrients like compost, worm castings, or slow-release fertiliser. Avoid using garden soil as it may contain weeds, pests, or diseases that can harm your plants.

Tip: When filling your pot with soil, leave a gap of about 2in (50mm) at the top to make watering easier. This will also help prevent the soil from washing away during heavy rains.

Planting Your Tomato Seedlings

Before planting your tomato seedlings, it’s important to harden them off by gradually exposing them to the outdoor environment. Start by placing them in a sheltered area for a few hours a day and gradually increase the amount of time they spend outside over the course of a week.

When it’s time to plant your seedlings, dig a hole in the centre of your pot that is deep enough to accommodate the roots. Gently remove the seedling from its container and loosen any tangled roots before placing it in the hole.

When planting your tomato, make sure to bury the stem up to the first set of leaves. This encourages root growth and a stronger plant.

Backfill with soil and gently pat down around the stem to ensure the plant is secure. Water the soil well and add a tomato cage or stake to support the plant as it grows.

Watering and Fertilising Your Plants

Tomatoes need consistent moisture to grow and produce fruit. To maximise the nutrient and water uptake of your tomatoes, water your plants well once a week, or more frequently during hot and dry weather, and make sure to check the soil moisture level daily. Be sure to water the soil, not the leaves, to prevent fungal diseases.

To ensure your plants have the nutrients they need, fertilise them regularly with a balanced fertiliser. Look for a fertiliser that is specifically formulated for tomatoes, or use a slow-release fertiliser at the beginning of the growing season.

Caring for Your Plants

Tomatoes grown in pots require some extra care to ensure they stay healthy and productive. Here are a few of our tips to keep in mind:

  • Prune your plants regularly to encourage strong growth and fruit production. Remove any suckers as they appear. Suckers are the new shoots that grow between the main stem and the branches. Removing suckers will help the tomato plant focus its energy on producing fruit.
  • Provide support for your plants by using a stake, trellis, or cage. This will prevent them from flopping over and getting damaged.
  • Tomatoes are susceptible to pests and diseases, so it’s important to take preventative measures. Keep an eye out for common tomato pests like blight, aphids, whiteflies, and hornworms, and use insecticidal soap or neem oil to control them. Also, keep your tomato plants well-spaced and pruned to improve air circulation and prevent fungal diseases like powdery mildew. If you notice any signs of infestation or disease, take action immediately to prevent the problem from spreading.
  • Harvest your tomatoes when they are ripe but still firm. Avoid letting them over-ripen on the vine, as this can lead to splitting and rotting.
  • Also, keep your tomato plants well-spaced and pruned to improve air circulation and prevent fungal diseases like powdery mildew.

Harvesting Your Tomatoes

Once your tomato starts to ripen, it’s time to harvest. Gently twist or cut the tomato from the plant when it’s fully coloured and slightly soft to the touch. Store your tomatoes at room temperature and enjoy them fresh, in salads, or cooked into your favourite tomato-based dishes.


Do Tomato Plants Need a Lot of Sunlight?

Yes, tomato plants require at least 6-8 hours of sunlight per day.

How Many Tomato Plants Can I Grow in One Pot?

It’s best to limit your pot to one tomato plant to ensure that it has enough space to grow and produce fruit. However, if you have a very large container, you may be able to grow two plants, as long as they are well-spaced and have enough room to grow.

What is The Best Time of Day to Water Tomatoes?

It’s best to water your tomatoes early in the morning, as this allows the plants to absorb the moisture they need before the heat of the day sets in. Avoid watering in the evening, as this can lead to fungal diseases.

Can I Grow Tomatoes in a Hanging Basket?

Yes, tomatoes can be grown in hanging baskets, but you need to choose a variety that is well suited to container gardening. Look for compact, determinate varieties that don’t require a lot of support. You will also need to make sure the basket is large enough to accommodate the plant’s root system and has good drainage.

Can I Reuse Soil From Last Year’s Container Garden?

While it’s possible to reuse soil from a previous container garden, we do not recommend it, as the soil may contain diseases, pests, or depleted nutrients that can harm your plants. It’s best to start with a fresh, high-quality potting mix each year.

How do I Prevent my Tomato Plants From Getting Too Tall? 

To prevent your tomato plants from getting too tall and spindly, you can pinch off the growing tips once they reach a certain height. This will encourage the plant to branch out and produce more fruit. You can also use a stake or cage to provide support and prevent the plant from toppling over.

Growing Tomatoes in Containers is a Good Option
