The tomato originated in the Andes, South America where tomatoes grow wild. It is believed that they were first cultivated by the Aztecs and Incas, possibly as early as 700 AD. The tomato plant arrived in Europe in the 16th century, supposedly brought back from Central America by the Spanish Conquistadors, although another legend suggests that two Jesuit priests took them to Italy from Mexico.

At that time tomatoes were also known as wolf’s peach and Peruvian apple. In the UK, the Elizabethans thought the bright red colour of tomatoes was a danger signal and regarded them as dangerous fruits. In fact, it is true that tomatoes are related to the nightshade family.

Tomatoes are sub-tropical plants and therefore require a full sun position when grown in temperate zones. A position against a wall or fence will give an even better chance of success as long as they can receive sufficient water.

Tomato plants grow very well in raised beds, they appreciate the soil conditions which provide moisture without water-logging.

Two or three weeks before planting, dig the soil over and incorporate as much organic matter, such as compost or well rotted manure, as possible. The aim is to make the soil able to retain the moisture needed so much by tomatoes.

Tomatoes are unable to tolerate any degree of frost, the timing for planting or sowing outside is therefore key to successfully growing tomatoes. If the tomato seeds are to be sown directly outside (not really suitable in cooler climates), they must be sown when the soil temperature is (and will remain) above 10C (50F) – any lower and the seeds will not germinate. In practical terms this normally means 3 weeks after the last frost date in your area.

Where the seeds are sown under cover (poly tunnels or cloches) or indoors, aim to sow the seeds so that they reach the stage where they can be transplanted outside, three weeks after the last frost date.

Tomato plants plants take roughly 7 weeks from sowing to reach the transplanting stage and they should be transplanted outside one or two weeks after your last frost date. Therefore you should sow them 7 weeks before you plan to transplant them outside.

Bush varieties do well for cultivation outdoors because they require no pruning for most of the season. Remove any yellow or decaying foliage as soon as possible to avoid the spread of disease.

If your bush tomatoes become too large to support themselves, either trim out a few major branches or add more support canes – the side branches can then be tied into the additional support canes. Limit the number of trusses of tomatoes to seven or eight by pinching out any surplus ones.

Upright varieties are commonly cultivated in pots, grow-bags, the greenhouse and sometimes outdoors in open soil. When the first fruits begin to form, the plant will produce side-shoots in between the main stem and the leaf stems.

These side shoots should be removed by pinching them out with the fingers. If allowed to grow they will produce a mass of foliage but few tomatoes. Any shoots which have been overlooked and allowed to grow should also be removed.

Lower leaves which show any signs of yellowing should also be removed to avoid the risk of infection.

When the plant has developed six or seven trusses of tomatoes (normally around July time), ’stop’ the plant by breaking off the growing tip. If any more than seven trusses of tomatoes begins to develop, pinch them out to encourage the plant to produce good quality tomatoes rather than an abundance of low quality late-maturing fruit.

Pick as soon as the fruits are ripe (colour and size will identify this) for the best flavour – eat as soon as possible. This also encourages the production of more fruit. As soon as a frost threatens, harvest all the fruit immediately and ripen them on a window sill. With upright varieties, it is possible to gently flatten the plants onto the soil and cover with horticultural fleece to protect them from the frost.

Did you know there are almost thirty varieties of tomatoes today? According to the U. S. department of Agriculture, people in this county eat over 22 pounds (per person) of tomatoes each year, half of this going to ketchup, sauces and soups. Tomatoes are highly popular, whether you think they’re a fruit or vegetable, it doesn’t seem to matter, people eat them up. Tomatoes can be expensive to buy in the super market and it’s no telling how old they actually are. There really is no reason to buy them, especially since this article is going to tell you how to grow tomatoes and you will find they are so easy to grow at home.

All you need is a good pot with good drainage and some good dirt or a little space outside and you’re all set. Tomatoes really like a dark, loose soil with organic matter and nutrients and a little acidity (about 6.2 pH) is best if you want really big red tomatoes.

 If your going to grow in a pot instead of in the ground, be careful when fertilizing and don’t add too much, maybe about a tablespoon to a 10 gallon pot and work this into the soil at least two weeks before planting. If planting outdoors a 10-52-17 or 15-30-15 fertilizer will be all your tomatoes need and about a cup scattered around the plants roots or seeds will keep your tomato plants well fed.

Staking your tomato plants will improve fruit production considerably and it also makes getting to your tomatoes much easier. If you’re planting seeds go ahead and place your stake in the dirt close to the seeds, this way you won’t disturb their roots once they start growing. If buying young plants, gently push your stakes in close to the plant and try not to disturb the roots as little as possible. Use a soft twine or yarn to tie your plants to the stake and remember to leave room for growth. Small tomato plants don’t usually need to be cut back or pruned but tall tomato plants may need a little clip here and there in the beginning. Just a little off the top and on the sides should be all the pruning your plant or plants need.

If you have a place picked outside for growing tomatoes, make sure you space them at least 24 inches apart, 36 inches is better if you have the room. Planting tomatoes closer together will reduce air circulation and can set your plants up for disease outbreaks.

Tomato plants are about 95% water so they do need to be watered daily, even those tomato plants grown in a pot on a porch, and remember to make sure your pot has good drainage. Water your plants thoroughly and let excess water drain away from potted plants. For those plants outside, it’s a good idea to cover the soil around your plants with mulch, pine needles, hay or even plastic to prevent water evaporation. Now that you know how to grow tomatoes, you will find they grow pretty fast and before you know it, you will soon have vine-ripe tomatoes, better than any grocery store tomatoes.

Your tomatoes will be ready when their color is almost a perfect red, or yellow depending on the kind you plant. Tomatoes grown in hot weather, over 75 degrees will actually reduce the flavor of your tomatoes, so if you live in a hot climate, planting tomatoes where they will get afternoon shade will give you better tasting tomatoes. Once you pick your tomatoes don’t put them in the refrigerator, leave them sitting at room temperature and they will keep their flavor much better. Another good thing about knowing how to grow tomatoes is you will probably never buy them at the store again.
