I am wondering if anyone can tell me what the best soil ph for tomatoes should be?

Optimum PH range for tomatoes 5.5 - 7

can you tell me how often to water tomotoes in hot house in tassie

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. :)

My tomatoes have little black spots on the leaves, what is this from and how do I treat it. Also the fruit is still green but som have been stung (?) by something as they have worms in them

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.

i have rosmary growing next to my tomatoes in a pot will this have a efect on my tomatoes growing in a pot next to them ?????????

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

Lyndall, Flowers not producing fruit could be due to too much water. with regard to the height, last year I let all the side shoots grow and that stopped vertical growth compared to this year where I have religiously trimmed out any shoots from the leaf joints and my plants which were planted 23 November are between 1 and 1.4 metres high. My theory is that if you let the side shoots grow a bit it will stop trying to grow vertical because the plant needs to keep flowering and the only way to flower is to produce new growth. This growth comes from the main stems or new stems nearer the bottom of the plant. I have 4 plants so am going to let to bush out more and keep 2 growing vertical. If you let the plant grow up through the wire the possums will do the trimming for you.
