  • S = Plant undercover in seed trays
  • T = Plant out (transplant) seedlings
  • Grow in seed trays, and plant out in 4-6 weeks. Sow seed at a depth approximately three times the diameter of the seed. Best planted at soil temperatures between 61°F and 95°F. (Show °C/cm)
  • Space plants: 16 - 24 inches apart
  • Harvest in 8-17 weeks.
  • Compatible with (can grow beside): Asparagus, Chervil,Carrot, Celery, Chives, Parsley, Marigold, Basil
  • Avoid growing close to: Rosemary, Potatoes, Fennel, Cucumber
  • Tomatoes on plant
  • a)  Seedlings
  • b) 6 weeks old
  • c) Tomato Roma (acid free)

There is nothing like the taste of a freshly picked tomato, warm from the sunshine. In the smallest of gardens or even an apartment with a window-box, it is worth growing at least one tomato plant for the pleasure it will give you. They will grow in pots, troughs or even hanging baskets.

Tomatoes should be grown in shelter or under cover in cool climates.

Tomatoes like lots of food! In a garden bed, compost and mulching will produce a crop from one or two plants. In containers, use some suitable long term fertiliser pellets or feed regularly when you water. Feeding improves the flavour of the fruit.

When you plant out, put the seedlings in a deep holes, up to the top set of leaves. The covered stems will put out extra roots and you will have a stronger, healthier plant.

There are many different varieties of tomatoes but they all have one of two growth habits.

Determinate:

Compact bush growth, stops at a specific height and useful for containers. If left without supporting stakes, they will form a dense carpet which excludes weeds and keeps the soil cool and damp.

Indeterminate:###

Will continue growing a main stem, or vine until stopped by frost. The majority of heirloom tomatoes are indeterminate.

Both types need stakes to give them some support otherwise they will sprawl across the garden.

Varieties include Acid-free, Bush, Tall, Cherry, Yellow and many others.

Culinary hints - cooking and eating Tomato

Use in sauces, with fried meals, in sandwiches. Can be frozen whole or in pieces.

If I’m in zone 8a, in an high rise with an outdoor patio. After taking cuttings of my cherry tomato plant prior to 1st frost, and putting cuttings in water to grow roots indoors, how long do I keep cuttings in water? Do I plant cuttings into small indoor pots prior to planting in larger outdoor pots for final growth, or keep them in water inside until final outdoor pot planting season?

Tomatoes being attacked by caterpillars picked one with a hole cut it in half and a caterpillar came out. They seem to be attacking before fruit has ripened. Will I need something stronger than pyrenthrium. Thanks

I've been growing tomatoes in the subtropics for years, the best insect/caterpillar repellents are barriers, which means bagging the fruit. Online sellers (don't want to name them here but the biggest one starts with an A), sell various sized drawstring fruit bags in bulk orders (20, 30 etc). These are reusable, I usually give them a soak in hot water at the end of the season to kill any eggs or pathogens, dry them and store them and I get several years out of them. I bag the baby tomatoes when the first tiny fruit forms as the bugs get there quickly. Yes, it is extra work. But it does work and avoids the need for harsh frequent insecticide spraying. The only tip I have about buying these is get the softer fabrics, there are some with a firm fabric that doesn't close well.

Best to grow tomatoes into the winter months. The summer early autumn time has lots of rain which is the breeding time for bugs and insects. After Easter plant seedlings.

Hi everyone, wondering if it is too late to sow tomatoes?

PLANT SEED OR SEEDLINGS. The information is here if you look for it.

I really enjoyed reading your tips on growing tomatoes! I'll try them out in my garden.

I’m planting Plum Lemon Tomatoes. Do I start in trays or sow directly into the container?

We have planted two different tomato transplants in our raised bed. Bed is about 18" deep. Have good soil, topped with compost, then covered with straw. How often should we be watering this time of year? Current daily temps are around 70-75.

If it is hot a good watering 3 times a week - not so hot 2 times a week. Small plants need small waterings more often. The finger test is a good indicator also.

Further to my posts below. I have found this which I believe is the problem with my bunchy curly leaves on cherry tomatoes. It is called -Tomato yellow leaf curl virus. TYLCV. Department of Agriculture and Fisheries Qld In March 2006, tomato leaf curl disease was found in cherry tomato crops in the south and west periphery of Brisbane. The disease has been found in many crops, with infection levels ranging from 5 to 100 per cent of plants. Losses in severely affected crops have been very high and the disease is a major threat to tomato production. In April 2006, infected plants were also found around Bundaberg. By June 2007, the virus was present in the Lockyer Valley, Fassifern Valley, Esk, Caboolture and Redlands areas. Since 2009 it has become a serious production constraint around Bundaberg. In February 2011, it was found in backyard tomato plants in Mareeba on the Atherton Tablelands. Tomato leaf curl disease is caused by viruses in the Geminivirus family of plant viruses, and is spread by whiteflies. The virus causing this disease is tomato yellow leaf curl virus (TYLCV). This virus is distinct from tomato leaf curl Australia virus (TLCV), which occurs in the Northern Territory and at several locations on Cape York Peninsula. Silverleaf whitefly (Bemisia tabaci Biotype B) was first recorded in Australia in 1994, it is now a widespread pest in Queensland and Western Australia and could become a major pest in most irrigated agricultural areas of Australia. Silverleaf whitefly (SLW) is also known as poinsettia or sweetpotato whitefly and in USA literature it is now referred to as Bemisia argentifolii. SLW has a wide host range (over 500 species) of crops and weeds, and is difficult to control as it has developed resistance to conventional insecticides. Biotype Q was discovered recently in Queensland. There is also an Australian native species. These three biotypes are indistinquishable in the field.
