My tomatoes are growing well, but they have started to exceed the 7' mark. Can I cut of the top of the bush so its not as high? Will this increase lower growth or will the plant go into shock and not produce?

Hi Dani, Sounds like they need a good fertilizing. You can take the new shoots from between stems and replant in seedling mix to keep over winter (inside). Otherwise tear out, plant some beans and then start over again in September. Good luck!

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. :)

You can look up the germination (seed hatching) temperature for various vegetables online. Compare this temperature to your soil temperature (even your air temperature to get an idea) -- the germination temperature needs to be met and sustained for the seeds to germinate (in addition to water, soil and presence of light for some shallow planted seeds). Most likely you will still benefit from starting indoors -- it all depends on temperatures AND which veggies you are planting - some veggies seeds have fairly low germination temps - beans, chard, mustard etc. Other veggies have very high germination temps: tomatoes, peppers etc. Remember that the germination temp needs to not only be met, it needs to be sustained. Since you can control your inside temperature - I would start my seeds indoors -- and potentially add a heating pad under the seedling tray. If you plant outdoors you can use a tarp to help warm the soil; I prefer clear elevated about 6" above the ground (like a green house) to help warm the soil when the sun hits it
