Help!! Dear All, I live in St Kilda in Victoria, my Tomatos which are only a couple of feet high are covered in clouds of whitefly, Ive tried everything, concoctions of sunlight soap and vinegar, pyrethrum, you name it but nothing seems to work. I have heard companion planting in conjunction with at least one other method is the best way but as i have tried so many different methods, i am somewhat sceptical. Does anyone have any tried and true methods to stop whitefly (other than not growing tomoatos)?

Hi David, I'm not sure if you have found a solution to your whitefly problem, but I thought i'd post this anyhow. I haven't tried this yet, but I saw a great segment on GA ages ago where Colin uses a vegemite 'tea' to attract lacewing, whitefly's natural predator. I found the fact sheet for you, but I can't post it. Just google it: Gardening Australia, fact sheet 'home-made remedies', series 20, ep 22, Presenter: Colin Campbell, 27/06/2009 Also, basil is a great companion plant to tomatoes, I tend to interplant them between rows. I hope this helps, and isn't too late!

will a tomato plant produce more than one crop?

It's true that tomatos are an annual but there IS a way to get"follow on" or late crops from a particular plant. . . take cuttings ("tip" or even better "heal" cuttings"take" eazily) The new plants will be genetically identical to the parent plant & will crop in 1/3 the time a seedling would. Best of all you can save a favorite (or a dozen if you wish) by overwintering in pots

Tomatoes are an annual so they grow then flower then they start to produce fruit and as long as you keep the water up to them and feed them regularly they should continue to flower and fruit for 4 to 6 months but when they are finished they dont usually bounce back the plant is spent. However small salad tomatoes (tiny tims,cherry tomatoes) have been known to flower and fruit again.

Look up 'Poisonous Plants' on wikipedia, there is a good list there. Tomatoes and potatoes are part of the nightshade family, which means any green bits are toxic. Brassicas would be a good choice, all sorts of fancy lettuce and chinese cabbage you could try and the seeds are usually cheap and easy to grow. (My amateur 2c)

Am trying to help set up a veggie/herb plot at my daughters child care centre but we have a problem. Tomato leaves (and potato) are posionus so will not be able to plant as children will have access to the garden at alll times. I know that a lot of veggies have poisonus parts but cant seem to find a list of them anywhere. Does anyone have any ides?

Hi, We planted small roma tomatoes about 4 weeks ago. The plants are thriving and heaps of flowers, but the flowers do not seem to be turning into tomatoes? Could it be over fertilisation? Really interested to hear your ideas. Thanks

It most likely will be short day-length - plants need enough energy to convert into flower and fruit production, and in winter there is simply not enough daylight in a day to do this. You should find that by October they will be forming fruit...

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.
