Hi David.. Whitefly can be controlled by using a low toxic product called Natrasoap. It suffocates the pests, then they dry up and fall off. You can also add a few drops of Peppermint or Eucalyptus oil as well.

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.

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, everyone. We've got a beautiful crop of tomatoes this year, with varieties including Rouge De Marmand, Tropic and a black variety I can't remember the name of. My problem is fruit fly (specifically, QLD fruit fly). Is there any way of eradicating this horribe pest? I've done some searching online which suggested fly traps may be beneficial but not much else. Help!

More information is needed: for example amount of water... soil conditions. The MOST GENERIC, and probably most correct answer is LACK OF NUTRIENTS. Most people plant their plants (tomato) adding lots of compost and/or manure at the time of planting. The plant grows using the nutrients (some are washed away... maybe trees manage to confiscate some nutrients); but as the soil nutrition drops, the plant, still wanting to grow, starts to take nutrition from its lower leaves so it can grow leaves higher up. That is, it is deciding how to best used it's own self to maximize it chances of success; since it can't source the needed nutrition from the soil What you need to do is: ADD manure or compost or anything else you may have to put nutrition back into the soil. I rinse my coffee pot in the garden, I also try to drain things (like the water from soaking dried beans) into the garden. Manure/compost/nutrition (in any form) needs to be added at planting, middle of the season, and close to the end of the season to give that LAST burst of energy to bring the fruit/vegetables into full form. Don't feel like you need to spend a lot of money; get creative; in Canada we can stop by our local coffee shops and pick up the days used grinds for use in our gardens (free); you can add micro nutrients to your garden by filling a pail with water and adding a layer of rocks (rocks are minerals) stir and use this to water your plants. Left over tea bags, left over coffee grinds, stuff that you might rinse down the sink (food juices), blood from meat when you wash it before cooking it ..... anything like that all puts nutrition back in the soil.
