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.

Hello, what kind of tomato variaties can be grown in East African conditions more so in central Uganda.

Look up on the internet or phone seed selling companies. Go to local nurseries and ask.

If you set your climate to summer rainfall and look in tomatoes, it is right in front of you, plant SEPT TO MARCH.

To keep the slugs, caterpillars from Tomatoes and other vegetables away break egg shells up and spread around plants. Works great

We have been experiencing very hot, dry days. Up to 42 degrees Celsius. Could this be the reason that my tomato plants died? They were watered regularly & kept in the shade.

I think it could just be seasonal. My tomatoes were going great (Nov and into Dec picking) and towards the end the whole plant just died off quite quickly. Same conditions as you, hot weather. In a lot of crops you can have early mid and late season varieties.

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
