It is Magnesium deficiency. A suggestion is to put two teaspoons in the bottom of the hole when you transplant. Mix it into the soil. Or apply some around the base of the plant (two feet diameter) and water it in.

With some arrays of flowers on my tomato plants there is a single large flower. Why is there one large flower? Would be very grateful for a reply,

From a crop (3-4 plants) of tomatoes ( I mainly grow Cherry) a lot fall on the ground - grub holes etc. In a few weeks/months time heaps of seedling come up. I just transplant them. I can grow tomatoes all year round.

Another method is to just cut slices and place them in the soil and cover them over. Or just take a tomato or a few if small and squash them up in a tray of water - in a few days they will ferment - leave for a few days. Then plant the seeds or separate the seeds and dry them out and keep for later on.

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 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!
