My tomatoes are growing well, but they have started to exceed the 7' mark. Can I cut of the top of the bush so its not as high? Will this increase lower growth or will the plant go into shock and not produce?

Hi Dani, Sounds like they need a good fertilizing. You can take the new shoots from between stems and replant in seedling mix to keep over winter (inside). Otherwise tear out, plant some beans and then start over again in September. Good luck!

I read that tomatoes shouldn't be fed until fruit starts forming, otherwise you end up with lots of lush leaves but no fruit. If the plant is too well fed it doesn't feel the need to reproduce itself. I always plant in good soil but don't feed until then.

Are there anybody around North-East Melbourne who would like to swap seeds/seedlings? I live in Greensborough. :)

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!
