I'd probably wait until September to sow seed in a cold frame to reduce the chance of having 'leggy' plants.

Thanks John and Mike. Will hold off until Mid to late August. Much appreciated.

Further to my posts below. I have found this which I believe is the problem with my bunchy curly leaves on cherry tomatoes. It is called -Tomato yellow leaf curl virus. TYLCV. Department of Agriculture and Fisheries Qld In March 2006, tomato leaf curl disease was found in cherry tomato crops in the south and west periphery of Brisbane. The disease has been found in many crops, with infection levels ranging from 5 to 100 per cent of plants. Losses in severely affected crops have been very high and the disease is a major threat to tomato production. In April 2006, infected plants were also found around Bundaberg. By June 2007, the virus was present in the Lockyer Valley, Fassifern Valley, Esk, Caboolture and Redlands areas. Since 2009 it has become a serious production constraint around Bundaberg. In February 2011, it was found in backyard tomato plants in Mareeba on the Atherton Tablelands. Tomato leaf curl disease is caused by viruses in the Geminivirus family of plant viruses, and is spread by whiteflies. The virus causing this disease is tomato yellow leaf curl virus (TYLCV). This virus is distinct from tomato leaf curl Australia virus (TLCV), which occurs in the Northern Territory and at several locations on Cape York Peninsula. Silverleaf whitefly (Bemisia tabaci Biotype B) was first recorded in Australia in 1994, it is now a widespread pest in Queensland and Western Australia and could become a major pest in most irrigated agricultural areas of Australia. Silverleaf whitefly (SLW) is also known as poinsettia or sweetpotato whitefly and in USA literature it is now referred to as Bemisia argentifolii. SLW has a wide host range (over 500 species) of crops and weeds, and is difficult to control as it has developed resistance to conventional insecticides. Biotype Q was discovered recently in Queensland. There is also an Australian native species. These three biotypes are indistinquishable in the field.

Planning to grow some heirloom cherry tomatoes when the time is right. Has anyone here in Vic -Aus had any success with the Florida Weave as a support method .? Cheers

They are grown similar to that commercially in Qld. They put a post in the ground each end of the row. Then 2" square posts each 5 m or so. As the plants grow they run wires along both sides of the plants. They then crimp the two wires together at the post. Rows are about 3-4' apart. I have done something similar this year - 2 posts 8' apart with a post in the middle. Run twine each 12" and pull together and tie at the middle post. Saves tying 10 times to a stake for each plant.

I haven't done exactly that but have seen it done. The advantages of it a easy vine management, easy picking, and more airflow which will reduce fungal problems.

I haven't grown tomatoes much - usually fairly cheap where I live. I have grown cherry tomatoes the last few years at the end of the growing season (Mar- Oct) and just let them spread all over the garden. Have had pretty good crops. This year I have staked them. I have planted Roma and Cherry next to each other. Done this twice. A row with 3 Cherry and 1 Roma. I know the Cherry tomatoes are Cherry because I just use them when they germinate from one that had fallen on the ground. The Roma I purchased seeds - can't be totally sure they are Roma. On a couple of the Cherry plants they start out big spread out leaves and then turn to very tight bunched leaves. You would think they are turning into Roma. IS there some deficiency in the soil to do this. And the Roma are just producing a lot of growth and little fruit. The fruit on 1 Roma is like a Cherry - very small. The weather here has turned cold for here, Night temps have fallen from low 20's to low teens in the space of 4-5 weeks. Last night was about 8. Anybody have any clues to what is happening to my tomatoes. Help!!!

Try some potash on your tomatoes. This will encourage them to fruit. And cut down any other fertilizer you might be using. As Sean has said, there could be too much nitrogen.

I have usually dug in some mulch and let it rot, put a bit of lime on and some fert N- 15.3 - P-4 - K 11.7. I know this is high N and will be using one with about 12 N 3.5 P and 14 K in the future (recommended by fert company that supplies to a lot of commercial growers of veggies around here). From the above I generally have very strong looking plants - I will say I realise I should cut back on the N and will be in the future. I have just started to make some compost the last few months. On a replanting now, I'm putting on about 3 x 20 liter buckets of compost/mulch per sq meter and adding lime and some fert. Will see how that goes - still probably too much N. I'm also adding some trace elements and Epsom salts to my soil. It should be good soil lol

Cherry tomatoes do tend to have smaller, more deeply cut leaves and Roma has larger flatter leaves. This is not a rule though as they are both derived from the same wild species. If you have a lot of large, leafy growth it could indicate an excess of nitrogen which will stimulate leaf growth at the expense of fruit. trust this helps.
