I have read that you can pinch out the laterals (the new shot where the leaf joins the stem) of tomatoes and put that in water and start a new plant. Maybe try that. Can only give it a go or buy some seeds from :The seed collection company" - out of stock at the moment. 200 seeds for $1 + postage.

Yes, doing that really works and I have been doing this all year. I also grow plants from tomato slices placed in seed raising mix. Wonderful results.

Hi there, to tie up all my tomatoes etc I have used an old cotton/polyester sheet that I have torn into strips about 2cm wide. You get heaps of “ribbons “ and can even buy an old sheet from vinnies for $6. The polyester makes them last and they are soft on stems unlike twine and the like. Also old stockings are excellent! Cheers.

I have used old clothes sheets towels all my life. I'm now trying a couple of posts with wire mesh between them. Train the plant in and out of the wire mesh and can use twine etc to support them also. Saves having dozens of pieces of cloth.

Hi I love tomatoes but don't have any luck growing them without white fly or aphids impregnating them. I've tried white oil but with no luck. Does someone out there have the solution as I love growing them and especially eating them. Cheers

Try a mix of LUX soap flakes. Mix 2 table spoons of flakes with 500mls of warm/hot water. Then mix with 5 liters of water and spray both sides of the leaves - do this every 4-5 days. Do the leaves curl up and not grow? Try growing in a different spot. .

Hello, is it too late to sow tomatoe seeds now (mid October)?

You could probably grow tomatoes all year round. Maybe better to plant some good strong seedlings - like about 6-9" tall. Next year plant a bit earlier. I transplanted some small seedlings out 2 days ago. If your soil is nice and fertile mulch around the plants and keep the water up to them.

Look up the internet. Maybe a garlic and chilli mix.

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!
