Lime

Remember, tomatoes hate lime and dolomite as they raise PH, use gypsum and stacks of compost to loosen soil instead (make sure it's real compost though, not stuff that has whole bits of fruit and vegetables that haven't broken down in it). They thrive in acidic, low PH soils with great drainage.

Try growing them in large pots with good potting mixture mixed with lots of compost and pelleted animal manure. A poultry/ cow manure blend is good.

A handy hint for protecting tomatoes: cut open a one or two litre clear plastic water bottle at both ends and place over the small seedling. This protects from birds and wind until they grow a little larger.


Diseases and fruitfly in tomatoes

If Fungal and bacterium wilts are a problem in your area try planting ES58s, Scorpio, Manapal, Burnley Surecrop and Romas as they have resistance to some forms of wilts. The symptoms of various wilts include yellowing/ browning of leaves normally from ground up. Diseased plants need to be removed and thrown in the rubbish/ away from garden, as the disease will spread. As for fruitflies, they are a big problem in Queensland. Try growing a variety called Hardy Tom or plant in late autumn to ensure a crop in winter (in warm areas) when fruitflies are least active. My tomatoes fruiting in Brisbane's winter have had no problem with fruitfly. You can also try protecting netting, but this needs to be gap free as the fruitflies are very small. Symptoms of fruitfly are fruit falling/ rotting on the ground with maggots inside. Sprays and traps for fruitflies are largely ineffective and can affect beneficial insects like bees so chose your methods wisely.

Origin of Tomatoes

This fascinating member of the deadly nightshade family is delightfully delicious and versatile. It was probably first domesticated by the Mexicans earlier last millennium. Their name for it was tomatl (and also Nahuatl) - in the Anahuac language spoken at the time. It was reputed to be one of the ingredients used when some of the pre-European Indigenous people of South America used to have people for dinner, after they'd rolled down the steep steps of pyramids following participation in a sacrificial ceremony that left them feeling a litttle light-headed.  

The Spanish decided to call them tomata (the tomatoes that is, not the unfortunate persons used to prepare stew) and went about spreading small pox, taking gold and killing lots of people with their spiky swords in the process before sitting around the campfire drinking hot cocoa.

The Spanish probably brought back tomatoes to Europe around 1523. I can't be sure of the exact date but if anyone is willing to sponsor a trip to the area, please let me know as I am willing to go to Ibiza to find a more precise date.

The earliest European records of it date back to 1544, when an Italian botanist by the name of Matthiolus described it as pomodoro: golden apple. He was possibly describing one of the yellow varieties.

To begin with, this fruity vegetable was thought, by Europeans, to be a little suspect. Columbus brought a few back and people thought they were poisonous. (The Latin name is derived from words meaning wolf and peach: referring to the fruit's supposed deceptive nature). Of course Europeans weren't that adventurous in those days and many still thought the earth was flat.

After most people agreed that the earth was probably round, they began inventing thousands of very tasty dishes that included the tomato. And the world is thankful that they did.

Apart from the most common red varieties, tomatoes occur naturally in a heap of colours including: white, blackish, pinkish, purplish, orange, and green (with stripes). And they come in all shapes and sizes from the tiny little round cherry ones to big ruffley ones.

Most of the first tomatoes that were cultivated in Europe had quite uneven shapes.

The first famous smooth type was declared grosse lisse, by the French, meaning "fat and smooth".

If you can get your hands on some fresh Green Zebra tomatoes - they are green, even when ripe, though they do have a yellow tinge to them, and have stripes.

Grow a few different varieties so you can have fruit at different times during the season - and save the seed from them. They are self pollinating so you can be assured, with minimum effort, that you will be getting a true to type plant next season. That minimum effort would be: space different varieties about three meters from each other (just to avoid cross pollination).

You will get so much reward from growing your own. Especially since modern breeders design there flavourless fruit with thick "survive-the-rolling-around-the-supermarket-floors-a-bit" skin that is about as useful to anyone who enjoys their food as plastic fruit.

There is also a modern tendency to splice genes from weird flat fish with those of the seldom aquatic Solanum. And, so far, the old varieties of tomatoes, have yet to be linked to human mutations and abnormalities. We cannot be quite as certain with these new "innovations".

Search around for a good seed company that sells interesting seed.

I have provided the addresses for some here in Australia. The links for them are on the left-hand side of the page. All of them are good.

Tomato Cultivation

Tomatoes are a summery plant in cooler and temperate climates. They can grow throughout most of the year in sub-tropical and tropical climates.

They do not grow very well at both the North and South poles though recently on Gardening Australia some scientists based in the Antarctic sent pictures of some tomato plants growing in shipping containers down there to combat scurvy, so it is possible.

In Canberra last spring (on Fathers day - which is sensibly placed in spring in the southern hemisphere) I planted tomatoes near a brick wall with tree gaurds (3 stakes and a plastic sleeve) round them and lots of pea straw (piled up around the outside of the tree guard) and compost and manure to warm the soil a bit and they thrived even with the chilly Canberra nights. Canberra still has nights below zero in spring by the way. This runs contray to the old myth hled in southern Australian states - in pre-global warming days - of planting tomatoes on Melbourne Cup day (first Tueasday of November). I had great crops of tommy toes, green zebras and other varieties by Christmas Day. I've even had reports of people planting their tomatoes in early spring in Sweden by digging holes and putting relatively fresh manure at the bottom which while it decomposes lets off enough heat to keep them warm. It was also suggestted that in Sweden you sprinkle coffee grounds around them to keep the deer away as the deer associated the smell with hunters.

They love a little compost. Well, even lots of compost! They also respond well to seaweed fertiliser and small amounts of potash (for fruit set) and a nice layer of pea straw to keep their roots from drying out, whilst also supplying some nitrogen.

Many tomatoes (most actually) need to be staked like cherry tomatoes, beefsteaks, green zebras, tommy toes, black Russians, though some like romas should be okay by themselves. All of them should be protected from frosts, unless they have been inserted with genes from snowflakes - which may be difficult to do at home, but you could try putting snow and tomatoes in a blender and then call the result Yetti Tomatoes, though a more natural way might be to try a variety like the Nepal tomato, which may be a little hardier in the cold, or one of the Russian varieties, like purple or black Russians. When heavy frosts hit tomatoes will burn and go brown - might as well just replant if this happens.

All tomatoes make good companions to all sorts of basils, pyrethrum daisies, New Zealand spinach and marigolds (you can now get white marigolds if you don't like the yellow ones).

Grow different varieties for different purposes and for different times of the season. You can get early ones like rouge de marmande and romas, mid-season ones like most cherry tomatoes and late varieties like purple calabash and white beauty, for a steady supply for your salads, sauces and for drying.

Good luck, and may the white flies not visit you. And if they do, spray them with neem or pyrethrum and not nasty chemicals. After all, you might want to eat them.


Saving Seed for Tomatoes

Did you know saving your own tomato seed is very easy. All you have to do is squeeze the seed from you favourite varieties (buy some heirloom, old fashioned ones NOT the supermarket ones which might grow but which will be basically crap and corrupted in the long run) into a bowl and then cover with water. After a few days it should get some mould on top. This is good as it means the mucusey layer around the seed has broken down. Simply pour off the mouldy water through a fine sieve and wash thoroughly. Dry for a few more days then you can store the seed for a few months. I find it best used within one year, but if stored in a dry, moisture free, environment, it can be stored for several years, though as with all seeds the viability of the seed can degrade with age - that is fewer seeds will germinate as time progresses.
