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. :)

Black spots is usually "Early Blight", google it and have a look at some pics and see if it looks the same. There is not much you can do, its best to pull out the affected plants and throw them in the garbage. You can also trim off all affected branches, try keep the plants dry and make sure they aren't planted to close so lots of air can get through.

Well, it depends on how big the pot is (make sure you have it in a 19 litre container). I don't think rosemary's got deep roots so it should be fine as they won't compete against each other for space. Also make sure you fertilize them regularly because plants in pots tend to lose a lot of nutrients. I've got basil right next to one of my tomato plants and they're both fine. They're not in a pot tho.

I just moved into a new house and have inherited a bit of a garden and some plants. I'm new to gardening but would really like to start growing my own fruit and veg. I have 3 different types of tomatoes - what look like plum, small heirloom ones?? and a more rounder, larger variety (no labels on any). They were a bot worse for wear having sprawled on the ground for a few weeks.... I have tried to save them... they have been staked/supported and dead, browning or "excess" leaves taken off. They do have some fruits on them and more flowers but after 2 weeks they don't seem getting any bigger/riper though leaves still seem to be growing. I'm in Perth and it's starting to cool here. Have I missed the season? Can I get the rest of the tomatos to grow/ripen? And how long can I expect the plants to fruit? Do I need to keep fertilising them, and how often? Also is what do I do with the plant when it does get too cold/it is done fruiting? leave it? Pull it out and start again next year? Cut it back? I know there are a lot of questions but I haven't done this before. ;-) Thanks

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.
