There is nothing like the taste of a freshly picked tomato, warm from the sunshine. In the smallest of gardens or even an apartment with a window-box, it is worth growing at least one tomato plant for the pleasure it will give you. They will grow in pots, troughs or even hanging baskets.

Tomatoes should be grown in shelter or under cover in cool climates.

Tomatoes like lots of food! In a garden bed, compost and mulching will produce a crop from one or two plants. In containers, use some suitable long term fertiliser pellets or feed regularly when you water. Feeding improves the flavour of the fruit.

When you plant out, put the seedlings in a deep holes, up to the top set of leaves. The covered stems will put out extra roots and you will have a stronger, healthier plant.

There are many different varieties of tomatoes but they all have one of two growth habits.

Determinate:

Compact bush growth, stops at a specific height and useful for containers. If left without supporting stakes, they will form a dense carpet which excludes weeds and keeps the soil cool and damp.

Indeterminate:###

Will continue growing a main stem, or vine until stopped by frost. The majority of heirloom tomatoes are indeterminate.

Both types need stakes to give them some support otherwise they will sprawl across the garden.

Varieties include Acid-free, Bush, Tall, Cherry, Yellow and many others.

Culinary hints - cooking and eating Tomato

Use in sauces, with fried meals, in sandwiches. Can be frozen whole or in pieces.

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.

Tropical climate - plant tomato seeds May, transplant June and July. Your soil mix is very porous, it would dry out very quickly especially in hot Darwin. And with watering it would leach out the fertilisers. With your soil mix you probably needed to water 3-4 times a day. The wet season probably leached all the Dynamic Lifter out of the soil. Ok- potting mix has a lot of wood in it. Material like this grabs the nitrogen before the plant does. Compost would do the same if it is not completely broken down. Here is what I do, sub tropical, in the fallow season Nov to April, I dig/turn my soil over adding grass clippings, shrub trimming etc mulched with the mower. With normal rain it will keep this moist and help break down the grass etc. You can add a little D Lifter. By late April /early May after the wet season you should have some good friable soil (depends what the original soil was like). You could add some more compost if you like and maybe manures, about 3-4 (?)
