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.

Hi collegues, Do you know any USA quarantine insect pests of tomato? Looking forward to getting your ideas Theo

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...

Hi. I'm not an expert gardener but maybe the flowers aren't being pollinated? You might need to get out into the garden and give the flowers a good shake. There are some very helpful you tube clips showing when the flowers are ready. HTH.

You can look up the germination (seed hatching) temperature for various vegetables online. Compare this temperature to your soil temperature (even your air temperature to get an idea) -- the germination temperature needs to be met and sustained for the seeds to germinate (in addition to water, soil and presence of light for some shallow planted seeds). Most likely you will still benefit from starting indoors -- it all depends on temperatures AND which veggies you are planting - some veggies seeds have fairly low germination temps - beans, chard, mustard etc. Other veggies have very high germination temps: tomatoes, peppers etc. Remember that the germination temp needs to not only be met, it needs to be sustained. Since you can control your inside temperature - I would start my seeds indoors -- and potentially add a heating pad under the seedling tray. If you plant outdoors you can use a tarp to help warm the soil; I prefer clear elevated about 6" above the ground (like a green house) to help warm the soil when the sun hits it
