I'm looking for a large juicy tomato to just plain eat whole. Looking for a good producer. Can't seem to find a recommendation for my area!

Google big tomato varieties. Most crops will grow from cold weather to hot weather, just have to plant at the right time of year for your area.

Let it die off and start anew. Even indeterminate tomatoes are annual and not perrenial. It could survive in a warm sheltered area but you will very likely be disappointed with a new season crop. Disease is likely to take hold of the plant as well causing further stress.

The KILL temperature for tomatoes is 2c. If you expect your night time temperatures to be below 4c, I would cover the tomato plant with plastic, and remove the plastic in the morning. The plastic should not be touching the plant. You can cover the plant umbrella style or tent style (fully enclosed like a mini green house). If for some reason you expect to get a really bad cold snap, I would dig the plant up, taking as much soil as possible, you can place the root ball on a piece of plastic (tarp and wrap the root ball), or on burlap, or in a pot, or in a cardboard box... whatever, then move the plant into the shed/garage/on a covered porch close to the house and keep it there until the temps warm up again. The goal when temperatures drop is too keep the morning dew off the plant, and if possible provide warmth by placing it close to the house, or in a enclosed shed.

Tomato seedlings get up to about 2 inches high, then just fall over and die. Spinach did the same. In tropical Darwin. Tried growing seedlings in trays first, plant them out only to loose them about a week later. Trying to Grow in a raised bed as no success into garden soil. Raised bed built mostly of potting mixtures with bags of compost and sand added. Lots of Dynamic lifter, turned over and left fallow for the wet season. Seedlings did the same death rate in the raised bed. What am I missing. Been here for 3 years and first season crops were really abundant. Now everything dies except for my Lime, Lemon and Guava Trees. Is it just to hot for Tomatoes and spinach now?

More information is needed: for example amount of water... soil conditions. The MOST GENERIC, and probably most correct answer is LACK OF NUTRIENTS. Most people plant their plants (tomato) adding lots of compost and/or manure at the time of planting. The plant grows using the nutrients (some are washed away... maybe trees manage to confiscate some nutrients); but as the soil nutrition drops, the plant, still wanting to grow, starts to take nutrition from its lower leaves so it can grow leaves higher up. That is, it is deciding how to best used it's own self to maximize it chances of success; since it can't source the needed nutrition from the soil What you need to do is: ADD manure or compost or anything else you may have to put nutrition back into the soil. I rinse my coffee pot in the garden, I also try to drain things (like the water from soaking dried beans) into the garden. Manure/compost/nutrition (in any form) needs to be added at planting, middle of the season, and close to the end of the season to give that LAST burst of energy to bring the fruit/vegetables into full form. Don't feel like you need to spend a lot of money; get creative; in Canada we can stop by our local coffee shops and pick up the days used grinds for use in our gardens (free); you can add micro nutrients to your garden by filling a pail with water and adding a layer of rocks (rocks are minerals) stir and use this to water your plants. Left over tea bags, left over coffee grinds, stuff that you might rinse down the sink (food juices), blood from meat when you wash it before cooking it ..... anything like that all puts nutrition back in the soil.
