Tomatoes. With their vibrant colours and diverse shapes, from the hefty beefsteak to the petite and sweet cherry varieties, they are as versatile as they are delicious. They also happen to thrive in the warmth and sunlight, making them ideal for Australian gardens.
Growing tomatoes at home is not just for seasoned gardeners – it’s a rewarding project for anyone willing to get their hands a little dirty. There’s something truly satisfying about nurturing a plant from seedling to harvest, watching it transform and eventually bear fruit.
Tomatoes are wonderfully versatile in the kitchen, too. They can be the star of a fresh salad, the base of a hearty pasta sauce, or a sweet addition to a summer salsa. With a few steps and patience, you can ensure a bountiful supply of these juicy gems all season long!
Understanding the Growing Basics
There are plenty of great vegetables to grow in Melbourne, and tomatoes are very high on the list. Whether you start from seeds or opt for transplants, there are a few key considerations to keep in mind to ensure your plants thrive.
Seed vs. Transplant
If you’re starting your tomatoes from seeds, giving them a head start indoors can lead to stronger, healthier plants come transplanting time. However, it’s crucial not to overcrowd your seedlings. Planting them too closely together can stunt their growth. To avoid this, ensure each seedling has enough space to spread its roots by planting them in individual pots as soon as their true leaves emerge.
On the other hand, purchasing transplants offers convenience and a bit of a shortcut. You can find a variety of tomato transplants at garden centres or nurseries, allowing you to skip the initial germination phase. Just be sure to choose healthy, vigorous plants with sturdy stems and vibrant foliage.
Sunshine
Tomatoes are sun lovers; ample sunlight is essential for their growth and fruit production. Aim to place your tomato plants in a spot that receives around 6 to 8 hours of direct sunlight daily. During the winter months, when natural light may be limited, consider supplementing with artificial plant lighting to ensure your tomatoes continue to thrive. Positioning your plants to maximise exposure to sunlight will encourage robust and stocky growth and ultimately lead to a more bountiful harvest.
Soil Preparation
Preparing the soil is critical for growing healthy tomatoes. While organic matter such as compost is often emphasised, it’s important to consider other soil types and amendments that benefit your plants. Tomatoes prefer slightly acidic pH soil, typically between 6.0 and 6.8. If your soil is clay-heavy or too sandy, consider amending it with perlite, vermiculite, or peat moss to improve its texture and drainage. Additionally, incorporating balanced fertilisers or specific nutrients like calcium can help prevent common issues such as blossom end rot.
Watering
Proper watering is key to ensuring your tomato plants stay healthy and productive. Aim to water consistently, keeping the soil evenly moist but not waterlogged. Watering at the base of the plant is preferable to frequent shallow watering, as it encourages deep root growth and helps prevent issues like fungal diseases. During hot, dry spells, be especially vigilant about watering to prevent stress and wilting. Using mulch around the base can retain moisture and regulate soil temperature, reducing the frequency of watering needed. With these basic growing principles in mind, you’ll be well on your way to cultivating a bumper crop of delicious, home-grown tomatoes.

Things to Keep in Mind for Good Plant Care
Tomatoes are voracious feeders, requiring regular nourishment to support their rapid growth and fruit production. There are various fertilising options available, including organic and synthetic choices:
- Organic fertilisers, such as compost or fish-based formulations, provide slow-release nutrients boosting soil health over time.
- Synthetic fertilisers offer a more immediate nutrient boost but won’t offer the long-term benefits of organic amendments.
Whichever option you choose, follow the recommended application rates and frequency to avoid overfeeding, which can lead to nutrient imbalances or plant burn. We also recommend the following:
-
Support:
Many tomato varieties, especially indeterminate types, benefit from support to keep their sprawling vines off the ground and prevent breakage under the weight of heavy fruit. Staking is a common method for supporting tomato plants, involving securing the main stem to a sturdy stake as it grows. This helps maintain upright growth and improves air circulation around the plant, reducing disease risk. Alternatively, you can use cages or trellises to provide support, allowing the plants to climb and sprawl as they grow.
-
Pruning:
Pruning tomato plants can enhance air circulation, reduce disease risk, and promote fruit production. Remove any suckers – the small shoots that form in the leaf axils – to redirect the plant’s energy toward fruit development rather than excessive foliage growth. Additionally, pruning lower leaves that come into contact with the soil can help prevent fungal diseases from taking hold. Use clean, sharp pruning shears, and be mindful not to remove too much foliage, as leaves play a vital role in photosynthesis and fruit development.
-
Pest and Disease Control:
Regularly inspect your plants for aphids, whiteflies, or fungal infections. If you notice any pests or disease symptoms, promptly mitigate the problem. This may involve hand-picking pests, applying organic insecticidal soaps or oils, or using natural predators to control pest populations.
Harvesting Your Tomatoes
Harvesting your homegrown tomatoes marks the culmination of your gardening efforts, but it’s important to know when and how to pick them for optimal flavour and storage.
Tomatoes come in diverse varieties, each with its unique flavour, size, and ideal picking time. Determinate tomato plants reach a set height and produce fruit that ripens all at once, making them ideal for canning or preserving. Indeterminate varieties produce fruit throughout the season, allowing for a staggered harvest. Depending on the variety, tomatoes may be ready for picking when they reach full colour and firmness, though some heirloom types may exhibit unique characteristics that indicate ripeness.
Proper storage prolongs the shelf life of your homegrown tomatoes. Avoid refrigerating tomatoes unless they are fully ripe and must be kept for a few extra days. Instead, store them in a single layer at room temperature, away from direct sunlight. If you have an abundance of ripe tomatoes, consider preserving them by canning, drying, or freezing them for later use. Additionally, storing tomatoes with their stems intact can help retain freshness and flavour.
What month do you plant tomatoes in Australia?
In Australia, tomatoes are typically planted in early spring, around September to October, when the soil is a little warmer.
Can you put Epsom salt on tomatoes?
Yes! Epsom salt can provide magnesium, which is beneficial for plant growth, but it’s essential to use it sparingly and according to recommended guidelines to avoid over-application.
What is the best fertiliser for tomatoes?
The best fertiliser for tomatoes often includes a balanced mix of nutrients, including nitrogen, phosphorus, and potassium. Organic options such as compost or seaweed extract are popular for feeding tomatoes throughout the growing season.
What should I plant next to tomatoes to keep bugs away?
Planting basil next to your tomatoes can help deter pests like aphids and whiteflies. Marigolds, parsley, and peppers are also beneficial companion plants for keeping bugs away from tomatoes.
