How To Grow

How to Grow Indeterminate Tomatoes from Seed

Tomatoes (Solanum lycopersicum) are members of the Solanaceae family. Tomatoes are annual plants.

Indeterminate tomatoes are also known as climbing tomatoes.

When to Sow Tomatoes

Tomatoes are a warm season crop. Use the table below to identify the best time of year to sow tomatoes in your climate.

Preparation

Tomatoes are best grown in full sun. Choose a location that will receive at least 6 hours of full sun each day.

Tomatoes need a well drained soil enriched with plenty of organic matter. Prepare soil by weeding it thoroughly, digging it over to loosen the soil and adding aged animal manure or compost. Keep the area free of weeds until planting.

Tomatoes are very susceptible to pests and diseases. Practice crop rotation to reduce the chance of pests and diseases becoming pervasive in your garden. Do not plant tomatoes in the same position two years in a row. Read more about crop rotation here.

Tomatoes can be grown in containers. If growing in containers use a good quality potting mix and make sure your container is large enough for mature plants; a minimum of 40 litres is recommended for tomatoes. During the growing season, keep in mind that container grown plants may need additional fertiliser to encourage healthy growth.

How to Sow Tomatoes

Tomato seeds do not require any treatment (eg soaking, stratification) before sowing.

Tomato seeds can be sown directly into the garden OR seedlings can be raised in trays or other containers and transplanted to the garden once established.

Sow Direct

  1. Sow seeds directly in the garden 5mm deep and 50cm apart, with rows 60-70cm apart.
  2. Keep soil moist but never wet or dry.
  3. Seeds should germinate in around 5-10 days at a soil temperature of 21-27°C.
  4. Young seedlings will need protection from pests, pets and weather until they are established.

Raise Seedlings

  1. Fill trays, punnets or jiffy pots with a good quality seed-raising mix, or use soil starter pellets.
  2. Sow seeds 5mm deep.
  3. Keep soil moist but never wet or dry.
  4. Seeds should germinate in around 5-10 days at a soil temperature of 21-27°C.
  5. Transplant seedlings to the garden once they have their first true leaves and are large enough to handle (usually 5-10cm tall).
  6. Plant out, spacing plants 50cm apart, with rows 60-70cm apart.

Tomatoes are a tender crop that’s sensitive to frost. Do not transplant seedlings or sow seeds outside until all danger of frost has passed.

Optional: In cool climates tomatoes can be started indoors 6 weeks before the last expected frost. Grow them in a warm position with plenty of natural light.

How to Grow Tomatoes

Tomato plants need to be staked for support. Use a sturdy stake or grow plants up a trellis or tripod. As plants grow, tie stems gently to the support using twine or plant ties. Make sure you have the support in place when you sow seed or transplant seedlings to avoid disturbing the plant’s roots later.

Tomato plants need regular watering during the growing season. Water when the soil is dry about 5cm below the surface (test this by scratching away a little soil with your finger). Water deeply in the early morning or late afternoon. Avoid watering the leaves of plants to avoid fungal diseases. Learn more about watering here.

Optional: Prune plants to two main stems to control growth, increase airflow and encourage the plant to put it’s energy into producing fruit. Read more about pruning tomatoes here.

If soil was well prepared no extra fertiliser should be necessary. In poor soil or to give your plants an extra boost, application of a balanced fertiliser or one formulated for fruit and vegetables can be beneficial:

  • Apply slow release fertiliser at the recommended rate when transplanting or when seedlings are 5-10cm tall.
  • Apply liquid fertiliser at the recommended rate and frequency while plants are fruiting or flowering.

How to Harvest Tomatoes

Tomatoes should be ready to harvest in approximately 85-90 days.

Fruit is ready when it starts to change colour. Harvest fruit by cutting with snips/secateurs or by twisting to separate from the stem. Harvest regularly to encourage more fruit. If stored at room temperature, fruit will continue to ripen after harvest. For short term storage, harvested fruit can be kept at room temperature. To extended the storage life, fruit can be kept in the fridge. For long term storage fruit can be frozen, canned or dried.

Problems You May Encounter when Growing Tomatoes

Tomatoes are usually a straightforward crop to grow. Most gardeners are able to grow productive and healthy plants without much need for additional care or intervention. However like all plants, tomatoes are susceptible to some pests, diseases and other problems, and when something does go wrong it's useful to be able to identify the cause and take appropriate action. Below is a list of the most common problems gardeners encounter when growing tomatoes:

Generic placeholder image
Aphids are small (2-4mm long) sap-sucking insects that congregate on the new shoots or the undersides of leaves. They can cause leaves to wilt or become discoloured, and also excrete honeydew which can attract ants and other insect pests. To manage aphids, remove them by spraying with a garden hose, apply a soap or alcohol spray, or encourage predatory insects to your garden. Read more about aphids here.

Generic placeholder image
Queensland Fruit Fly (Bactrocera tryoni) that lays its eggs in fruit, causing it to rot from the inside. Fruit will fall prematurely and larvae can be seen if affected fruit is cut open. Practice good garden hygiene by disposing of fallen fruit, protect fruit with insect exclusion netting and install traps to monitor fruit fly populations. Read more about Queensland fruit fly here.

Generic placeholder image
Whitefly is a sap-sucking insect related to aphids. They are often found in large numbers on the underside of leaves and will swarm in clouds when disturbed. Plants may have yellowing leaves or wilting, and growth will be slowed. Whitefly can be removed with a garden hose or sprayed with soap spray. Badly affected plants should be destroyed. Attracting beneficial insects that will prey on whitefly can be beneficial. Read more about managing whitefly here.

Generic placeholder image
Blossom end rot is a nutrient deficiency caused by a lack of calcium uptake, often due to inconsistent watering. Fruit will discolour from the bottom end upwards, with the affected area growing darker and harder. Dispose of affected fruit, water regularly and evenly, and correct soil pH and nutrients if required. Read more about blossom end rot here.

Generic placeholder image
Split or cracked fruit is most often caused by overwatering or too much rainfall while fruit is developing. The fruit grows more quickly than the skin, causing the skin to split. Watering evenly and mulching thickly can help moderate soil moisture, reducing splitting. Pick any ripe fruit before it spoils. Dispose of inedible cracked fruit as it can introduce rot and disease to the crop.

Generic placeholder image
Catfacing is a physical deformity of the fruit causing it to grow in a deformed, cracked and pitted way. Thought to be caused by low temperatures early in the growing season or damage to flowers, excess nitrogen (over fertilising) can also increase susceptibility. The fruit is still edible; cut out any deformed or hard pieces and consume what’s left.

Generic placeholder image
Sunscald will show up on fruit as white marks or blisters that often become moudly. Young, unripe fruit are most susceptible. Do not prune leaves from plants at the height of summer; leaves will help to shade and protect the fruit. Cover plants with a light fabric on very hot days to protect them from sunburn.

Generic placeholder image
Buzz-pollinated plants are pollinated when wind or insects vibrate the flowers causing pollen to be released. Lack of pollination will result in no fruit. To attract bees and other pollinators to your garden plant companion flowers among your vegetables. You can also attempt to pollinate the fruit yourself by gently shaking the plants or by applying an electric toothbrush directly to each flower stem for around five seconds every few days.

Generic placeholder image
Powdery mildew is caused by fungal spores reproducing on the leaves of plants. First showing as white spots on leaves, affected areas areas can spread quickly to cover the entire leaf surface. While rarely fatal, powdery mildew can reduce yields. Water plants at soil level (not on the leaves) to prevent spreading spores, allow good air flow between plants, remove affected leaves and if necessary spray with an appropriate fungicide or homemade spray. Read more here about powdery mildew here.

Generic placeholder image
Possums, birds and other animals can ruin a large percentage of your harvest overnight. Physically exclude pests by using netting or cages, or try spraying plants with a pungent homemade spray made from garlic, fish oil or mustard.

Generic placeholder image
Armyworms, cutworms and other caterpillars can all eat the inside of fruit, making it inedible. Young caterpillars burrow into soft fruit, leaving just a small telltale hole on the fruit’s skin. Monitor fruit and remove any caterpillars you see. If necessary use insect exclusion netting or fruit bags to physically protect the fruit, or spray with Dipel.

Generic placeholder image
Fusarium wilt and verticillium wilt are diseases caused by soil-borne fungi. The fungi enter a plants’ roots and prevent water and nutrients from moving through plants. Leaves and branches will wilt, dry off and die and leaves may yellow. There is no cure for wilt but choosing resistant varieties, disposing of affected plants and soil, practicing good garden hygiene and crop rotation will all help to prevent it spreading.
