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.

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!

Try a physical barrier, like exclusion bags, to keep the fruit fly off your tomatoes. I got some from Greeen Harvest last year, and they made a huge difference to the amount of fruit that survived.

Hello i live in QLD myself and a good cheap alternative to fruit fly traps is cheap sweet white wine -the cheaper, the better. Just grab an empty plastic bottle cut some small holes (5c coin size) near the top, string it up close to the plant (on the tomato stakes is preferable) and throw out when it's full. The flies love the smell of the wine and end up drowing in it. I've tried it with red wine but white seems to get better results. hope this helps:)

My tomato plants are just starting to bare fruit, but now the leaves are turning black on the ends and dying off. What should do.

It could be a fungal problem. I would take a couple of leaves into your local nursery/garden shop to show them.

I have one long garden bed (6m x 1.5m) this year just set aside to grow tomatos. I have planted a variety of types, common to all nurseries. This year half of my plants have taken (part shaded end of the bed) and started to grow while the other half (full sun) last about 1 week before all the leaves wilt and the plant dies (Surprisingly quickly). I have just tested and adjusted the PH as I found that it was a little low, but not drastically, in the sunny end of the bed. I don’t know why my plants keep dying but I can’t keep replacing them. Does anyone have any ideas what could be causing my plants to die? The only think that is growing in the same bed, surprisingly well, are the basil and marigold plants. I grew tomato’s quite successfully last year but in a different position in the garden.

I have had this problem, and was told it was nematodes. I am now going to grow them in pots, in the dry and see how they go in the wet. I am 220 km down the track from Darwin. Good luck

I am also from the Central Highlands, though this will be my first year trying tomatoes here. A lady with many years of gardening experience recently told me that tomatoes shouldn't be planted out here until Melbourne Cup day (5th November). It's simply too cold before then, especially overnight, and late frosts are still possible in October. For best results you should raise seedlings beside a sunny window or in a greenhouse in late September - early October, to plant out in early November. Or simply buy seedlings from a nursery - this is a much easier option but the number of varieties they sell is limited. I have researched on cold-tolerant varieties for this season and here are three that I am trying this year: Siberian, Stupice, and Swift. You may want to try to look for these varieties as they will probably be better adapted for this climate. Generally, any variety from Northern Europe is probably better to plant than typical Australian varieties, which are bred for hotter climates. Finally, make sure you are feeding them correctly. A high Nitrogen fertiliser is necessary early on, but once it puts on flowers you want to only feed it with one high in Phosphorus and Potassium. There are very few of these fertilisers that seem to be available at the big box stores (many have way too much N) but something like liquid potash or a 'flowers / bloom' labelled fertiliser should work. Make sure to include some organic fertiliser or organic compost when planting out your seeds / seedlings as well, so that your soil is not deficient in trace elements. I hope at least some of this advice helps and that you end up with a bumper crop this year. Tomatoes are probably harder to grow here than elsewhere but I have also been told there are less pest problems than up towards the tropics. Best of luck!
