These tomatoes were seeds from seedlings given to a seed seller who grew them out and harvested the seeds and sold them. They are from Guyra Glasshouse (NSW) - biggest tomato grower in Aus I read. These plants have been unbelievable. I grow them on trellises 6-7' long - 3 plants to a trellis. I have 3 trellises about 2.5' apart running N -S and another trellis at my house. The middle trellis of the 3 hasn't produced too many tomatoes - shaded by the others but gee have all the rest produced heaps. I don't know what variety they are (a hybrid) but they produce a lot of fruit and no disease or grubs. Have picked about 40kg and still have approx. 25-30 kg to pick.

re: end rot_ always put calcium of some kind in the planting hole then feed with powdered calcium and maybe spent coffee - diluted, a couple of times in the growing season. I collect all my eggshells and use, powdered, for all the mandrake plants, especially the ones in pots - once a month application for potted plants.\

Can I plant my tomatoes now and til April 24 without any damage to my plant. I plan on putting straw around them for added protection

I have been planting tomatoes in my veggie patch, but the fruit never goes a nice bright red, they are always blotchy orangey red. I have tried different varieties, but they all do the same thing. Is it the soil, or too much sun, or the bore water which is quite hard? They taste ok, just look unattractive. I was going to try growing them in pots this year, then at least I can rule out the soil.

I'm having problems with grub's in my yard and garden. Has anyone ever used a spray called milky spore. If any one has how long does it take to get rid of them. The moels are reeking havock on everything because of them. Dogs digging after the moels is a completely different story and problem. Any advice would be appreciated thank you.

Earth-friendly beneficial nematodes seek out and kill grubs and other soil-inhabiting insects. They come on a sponge (invisible to naked eye) that you soak in water, put in a sprayer and spray your dirt or lawn. They will multiply over time and continue to kill grubs You can buy them online or at your local nursery.

my roma tomatoes have got a big brown spot on the very end just as it starts to show colour, what would you say that is ?

Looks like is lacking calcium, normally we put fertilizer but we forget to put calcium, get some dolomite or some rock dust.

Use Epsom salt - a teaspoon in the hole at planting and even sprinkle another on top of the soil a few weeks later.

Blossom end rot by the sounds of it. Buy some Epsom Salts and put in your garden - from supermarkets. Couple of $$ for 1 kg.

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!
