Tomatoes need heat to grow and produce. If you can where the soil in the container will stay warm enough you could certainly give it a try. You would need maximum sunshine and protection from frosts and cold winds. I have heard of people putting pots against a brick wall so that some of the heat absorbed by the wall can help overnight. If you have a sunny spot near a window inside what about planting them inside in a pot or a hanging basket. 'Tumbler' is a good hanging basket variety that bears very well and looks good. Let us know on this site how you get on.

I agree that Tumbler is a great "cherry type" tomato, and a great performer. I grow both yellow and red variety. Plant two plants in each large hanging basket, feed well and you should get toms from Oct till April. I hang mine off the picnic table on my deck, we pick our own for meals, easy!

I planted a crop 6 plants of Roma in virgin beds this year and did quite well, how ever in years gone by have had poor results in beds previously cropped with tomatoes, why is this so?

The tomatoes would have done well because of your 'virgin' beds. Vegetables have varying nutrient requirements, with leaf crops able to take lots of nitrogen from recently manured soil. If you follow a leaf crop with a fruit crop, such as tomatoes, beans or pumpkins (or plants from within that family), then complete the cycle with a root crop such as carrots you will end up with a fairly good balance. After the root crop add more manure or compost and start the cycle again. The only extra thing I will say is - don't plant tomatoes, capsicums, potatoes or egg plant in the same spot next year as this will encourage soil borne diseases that they are susceptible to. Trust this helps.

Is it too late to plant a Roma tomato plant now? Ta

Roma tomatoes need about two and a half months from planting to harvest, so if you planted some now you would have them ready by late March. You should scrape in before any frosts. If they are still bearing and frosts are imminent pull the whole plant out (including the roots) and hang it up by in a sheltered place where the remaining tomatoes will continue to ripen. The worst case scenario would be to make green tomato pickles at the end of the season. Trust this helps.

Hi, I got about 5 varieties of tomatoes growing and they are all doing great and tasting fantastic! And totally organic as well.....my only problem is that I am sharing my delicious fruit with these big fat green caterpillars .....so I end up throwing a lot away.......would you have an idea what I could do to get rid of them? A non-chemical solution if possible.... Thank you :)

I don't like to recommend particular brands but Yates Natures Way is an organically safe control for your caterpillars. It is harmless to pets, chooks, humans, etc. only affecting chewing pests. The caterpillar could subsequently be eaten by a bird with zero side effects. Trust this helps.

It's probably too hot at the moment that's why the leaves looks crimped and blossoms is not opening. Try to give your tomato plant some shade and water them twice a day. Once the temperature cools down a bit, you should see an improvement. My tomato plant is doing ok so far with the daytime temperature up to 34C but they are growing very slowly due to the heat.

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
