I'll try that on my plum trees next year!

I am no expert, but I read somewhere that you can put banana skin under the mulch or in the soil and the potassium helps with flower production. I tried this and also made a tea of banana skins which I apply (diluted) weekly. It seems to work! There are lots of flowers and fruit even though we have had a very slow start to summer here.

I have tomatoes at 1.5 metres and the fruit is large on all plants. The problem is the plants look like they are starting to die off before the fruit ripens. We have chook so i have placed the waste on the ground around the plants ( the waste is a week old before it goes on). Suggestions please.

we've had so much rain, the soil in places is boggy but my tomatoes are in a new slightly raised bed. I've noticed blossom end rot on many of the plants. I guess the calcium has been leached out of the soil with all this rain, should I add some lime?

From experience night temps will stop flowers from bearing fruit. We in Armidale (Northern Tablelands NSW) have experienced 1 C over the last few weeks at night. However, I have pot plants in a secure under the eves and one self seeded plant lived through winter, and has beared a few fruit. Not the most healthy looking either. But has three tomatoes on it.I don't think Armidale is the best place to have tomatoes unless in a green house. They grow well but don't bear much fruit, as night time temps go beneath 10 C.

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?

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!
