Seems to be a few of these in the USA. Probably in aussie you would look for tomatoes for paste - like Roma, Super Roma and San Marzano. Best if you GOOGLED and have a look around for ones with more flesh than seeds.

Thanks folks. Importing seeds directly seems problematic because of bio-security issues. Tried Google & other engines and can find none of the USA varieties in Oz. + way too much contradictory info to be really useful (e.g. almost seedless to lots of seeds for the same type). Thought I'd try this forum. Thanks for the tips on the paste varieties. That provided a different focus for my searches.

The Diggers Club sell seeds for Amish Paste tomatoes. Perhaps one of their heirloom varieties might be what you're looking for.

Read the notes for tomatoes. Plant seeds now and keep in a warm place. After the frosts have finished plant out in the garden.

What variety of tomato have you planted. No, they will flower as they grow. If it is a bushy type of tomato most of the fruit will ripen at the same time. If it is an indeterminate type of tomato it will keep growing - as it grows it will keep flowering and when you come to harvest them, the harvest will be spread over weeks months. If it is not a bushy type (determinate) it can grow to several meters high.

How early can I grow tomato seed under a cold frame in Victoria? We don't get frosts, but I was hoping to start sow seeds late July then repot under cover a couple of times before planting out in the garden in October. I know traditionally you wouldn't plant out tomatoes until Melbourne Cup day. I've yet to grow any tomatoes in my garden as this is a new project. Any feedback would be beneficial

The guide says start seedlings in Aug Sept. Planting seeds and growing them for 1-2 mths isn't as easy as it sounds, especially if growing undercover. They can become spindly if trying to find light. I'd suggest you wait until August and after they have developed a few leaves give them some sunlight each day to toughen them up.

I'd probably wait until September to sow seed in a cold frame to reduce the chance of having 'leggy' plants.

I live on the North Shore, Auckland and have done container growing for several years now, This is the third year of growing tomatoes on a large scale - predominantly determinate varieties. I source my seeds from Kings Seeds who supply a determinate variety called Sub Arctic Plenty which I have experimented with variable results. All plants raised indoors, gently hardened off then potted out into 15L tubs. I use 50/50 new compost/previously used container soil from a non-tomato pot mixed well with added slow release fertiliser and half a cup of powdered eggshell.. The top is mulched with straw and 4 marigolds to attract the bees. They also need a 5ft stake. Generally the plants like the morning and late sun and need shade from the glaring hot midday temperatures. Each year I am growing them earlier to avoid the heat of summer. The pots on the decking facing North fully exposed struggled, the pots that were shaded midday grew much better. Next year I plan to plant out in July/August and see how they get on then. They have a mild taste, personally I prefer the richer flavours of the dark toms but they are good for dehydrating. I also found that they prefer dryer soil than some of my other varieties. I liquid feed them once a week using a litre of water. Don't let them stand in trays, they need full drainage. Any run off from the trays I use on something else (the pineapple sage is very grateful). Spay every part of the plant with a brew of bicarsoda to pre-empt and control powdery mildew weekly. Please let me know if you want any other info - happy to share. Let me know how you get on.
