For tomatoes what is the best ph level

6.5 is a common pH level for vegetables and works for tomatoes.

Look up ph levels for vegetables on the net. Then you will know for all vegies.

My tomato vines are full of fruit, all of it green. I've often had the problem of ending up with lots of unripe fruit at the end of the season so I was wondering it there is a sure-fire way of ripening the tomatoes on the vine before the first frosts?

My dad said he used to pull the whole plant out and hang it in a shed and the tomatoes would vine ripen then finish off on the windowsill.

Ethylene gas ripens tomatoes and some other fruit. Add a few bananas to them. Suggest you read up about how to ripen tomatoes on the internet. Read different articles. Also see if you can start your seedlings earlier in future so that they grow/ ripen earlier in future.

Also most fruit take a few weeks from being fully developed to then ripen, 3-5 weeks. Same applies to pumpkin, rockmelons, watermelons etc.

Any advice on best cool climate tomato varieties for a greenhouse in Melbourne between March and October? Thanks in advance

You are temperate, a greenhouse will raise the temperature in it. Most varieties would grow in it. Ask at your local nursery etc.

Unless your area is frost-free they are not likely to survive. We have them coming up in our garden because of a warm Autumn but the first frost will finish them.
