Types of Tomatoes
1. By Growth Habit
| Determinate (Bush types) | Indeterminate (Vining types) |
|---|---|
| – Compact, grow to a set height (around 1 m). – Produce fruit all at once over a short period. – Best for pots, verandas, or small spaces. Examples: Roma, Tiny Tim, Patio Princess, Bush Goliath | – Keep growing and producing fruit until frost or extreme heat. – Need staking or cages. – Larger harvest over a longer season. Examples: Roma, Tiny Tim, Patio Princess, Bush Goliath |
2. By Fruit Size & Shape
| Cherry & Grape Tomatoes – Small, sweet, bite-sized. – Heavy yield, easy for beginners. Examples: Sweet 100, Tommy Toe, Sungold, Red Grape. | Plum/Paste Tomatoes – Oval-shaped, thick flesh, low water. – Best for sauces, pastes, and drying. Examples: Roma, San Marzano, Amish Paste. |
| Slicing Tomatoes – Medium to large, juicy. – Great for sandwiches and salads. Examples: Grosse Lisse, Mortgage Lifter, Brandywine. | Beefsteak Tomatoes – Very large, meaty fruits. – Great for burgers and grilling. Examples: Beefsteak, Oxheart, Black Krim. |
3. By Colour
- Red: Classic flavour (Roma, Grosse Lisse).
- Yellow/Orange: Mild, low acid (Yellow Pear, Golden Sunrise).
- Green: Tangy, unique (Green Zebra).
- Purple/Black: Rich, smoky flavour (Black Russian, Cherokee Purple).
- Striped/Heirloom: Decorative, complex flavour (Tigerella, Mr. Stripey).
How to Grow Tomatoes
1. Choose the Right Variety
- Beginner-friendly (small, reliable): Cherry tomatoes, Grosse Lisse, Roma
- For verandas/pots: Bush/dwarf varieties (e.g., Tiny Tim, Patio Princess)
2. Growing Timeline
| Month | Stage | Tasks |
|---|---|---|
| Jul–Aug | Preparation | Prepare beds, compost, seed trays |
| Aug–Sep | Seed Starting | Sow seeds indoors/protected area |
| Sep–Oct | Seedling Growth | Pot up seedlings, increase sunlight |
| Oct–Nov | Transplanting | Plant outside after cold weather |
| Nov–Jan | Vegetative Growth | Stake, prune, fertilise |
| Dec–Apr | Flowering & Fruiting | Water deeply, harvest regularly |
| Apr–May | Final Harvest | Pick remaining fruit |
| May–Jun | Cleanup | Remove plants, rotate crops |
3. Soil & Pots
- Soil: Well-draining, rich in compost. pH 6.0–6.8 ideal.
- Pots: Minimum 30 cm deep for bush types; 40 cm+ for tall/vining types.
- Add slow-release fertiliser or worm castings before planting.
4. Planting
- Plant seedlings deeply (cover up to the first leaves) → encourages strong root system.
- Space: 40–60 cm apart (in garden beds).
- In pots, stick to one plant per pot.
5. Sun & Watering
- Needs 6–8 hours of full sun daily.
- Water deeply, 2–3 times per week → keep soil moist, not soggy.
- Water at the base of the plant (avoid wetting leaves to prevent disease).
6. Support & Pruning
- Use stakes, cages, or trellis for vining tomatoes.
- Pinch off suckers (small shoots in leaf joints) to encourage fruiting instead of leafy growth.
- Bush/dwarf varieties usually don’t need much pruning.
7. Feeding
- Start with a balanced fertiliser (NPK 10:10:10).
- Once flowers appear → switch to high-potassium fertiliser (e.g., tomato food, seaweed/fish emulsion).
- Avoid too much nitrogen (you’ll get lots of leaves, few fruits).
8. Pests & Problems
- Aphids / Whitefly: Plant basil or marigolds nearby, spray with neem or soapy water.
- Fruit Split: Caused by irregular watering → keep soil consistently moist.
- Blossom End Rot: From calcium deficiency/uneven watering → add lime or crushed eggshells.
9. Harvesting
- Pick when fruits are firm, full-coloured, and slightly soft to touch.
- Ripen green tomatoes indoors on a sunny windowsill if frost is coming.
- Harvest regularly to encourage more fruiting.
10. Storage
Whole tomatoes (best flavor)
- Unripe tomatoes:
Store at room temperature, away from direct sunlight.
A bench or kitchen counter is ideal. - Ripe tomatoes:
Keep at room temperature if using within 1–3 days.
Refrigeration slows spoilage but can reduce flavor and texture.
If tomatoes are very ripe
You can refrigerate them to extend life:
- Store in the fridge crisper drawer.
- Bring them back to room temperature for 30–60 minutes before eating to improve taste.
Long-term storage options
- Freeze: whole, chopped, or pureed.
- Dry/dehydrate: sun-dried or oven-dried tomatoes.
- Preserve: sauces, chutneys, canned tomatoes.
Extra tips
- Store stem-side down to reduce moisture loss.
- Keep away from bananas and apples if you want slower ripening, because those fruits release ethylene gas.
- Do not store wet tomatoes; moisture encourages mold.
For homegrown tomatoes in Sydney’s warmer months, good airflow and cool indoor temperatures help them last longer.
