I sow mine in late Sept in trays which i then put in the bottom of a large Sistema container with lid...I pop this out in the sun during day...moving lid around for heat and close it at night...if really cold pop in shed with a blanket....or do the same in the tunnel double walls/ can always throw a rug over the sistema for the morning undo the sistena and before long you have healthy plants. When planting out, i use cardboard boxes to cover at night, as less condensation and if really cold night.....pop that big Sistema over the cardboard box...really helps with protection. Had great sucess over the last few years. Also put sheep dags over the soil in the winter and dig them in before planting out...great microbiome and nitrogen for soil.

Does anyone know where I can source some seeds for the Alboran variety. It is a winter variety for very low temps.

What do I need to make a home made good potting soil for grow bags, to grow vegetables?

A simple potting soil can be made with peat or Coco coir, perlite and any compost in a 1:1:1 ratio. You can use steer manure from lowes or home depot since it is pretty cheap or if your city has a composting program use that for free compost. It's a good idea to add 1-2 cups of fertilizer per cubic foot of soil you prepare with the above recipe. If you want to keep it simple, but a 10-10-10 balanced fertilized and add 2 cups per cubic foot. If you want a more detailed and balanced soil recipe I recommend checking out Buildasoil for info

I live on the NSW Central Coast. I have been given some Siberian Tomato seeds from a fellow gardener. I have been told that they are pretty cold resistant. I planted seed in about April. All 5 seeds germinated. I gave 2 to a friend, planted one in a pot outside in half sun, and 2 in my garden. I killed the two in my garden with kindness. Too much fertiliser and water. The one in the bot has bloomed, is about 18 inches high and flowering. To complicate things there is a self sown Mini Roma which is about 3 ft high and booming, full of flowers and some fruit. Very keen to see how the Siberians will go through the winter. It is 1 July here cold nights frost free. Has anyone grown Siberians? Cheers Pete

Go to australian seed website and read about them - they just set fruit at lower temperatures, otherwise grow much the same as other toms. Better to grow just one bush in a 2-3' pot.

Right now my tomatoes are very big and look almost successful however they arn't turning red?! A few of them have but the rest are just happy sitting in greenville for quite some time. I would love some help! I planted around october from memory. Its they are beefsteaks. Thank you so much for your help. I would love to show my 7 year old that we can do this!

Hi Belinda, when I grew tomatoes in Armidale NSW, I used to pick them just as they started to turn, the put them somewhere dark and ripen them that way. Worked every time. Also didn't have to worry as much about birds and critters!
