Tomato Plants from Seedshow to grow tomato plants from seeds

Heirloom tomatoes are a variety of tomatoes grown from seeds that are usually over 50 to 100 years old. They are non-hybrid, open-pollinated cultivar tomatoes.

The use of the word heirloom can mean that the seeds have been passed down through generations, from farmer to farmer or parent to child and they are still growing today. Or it could mean any seed older than 50 or 100 years old; the jury is still out on this definition with many debates raging on for the use of heirloom to describe the wide variety of tomatoes.

What everyone does agree on is that an heirloom tomato needs to be an open-pollinated plant. This means it is pollinated by the wind, insects or birds, not man. And cultivar means that it is a plant species is being cultivated and given a specific name and that it can repopulate itself again in the same manor and retain all its characteristics.

There are several names of heirloom tomatoes available today which recently as ten years ago became available. There are over a hundred heirloom tomatoes and list grows every year as long as the tomatoes adhere to the standards put forth by the International Code of Nomenclature for Cultivated Plants (ICNCP) or the cultivated plant code.

Many of the most popular heirloom tomatoes are Brandywine, a large, pink fruit, red outside, clear inside, it has been said to have been grown from a seed passed to a farmer in an Ohio farm and then traded to several large seed companies who preserved it’s heirloom status.

In addition to Brandywine tomatoes, there is the Cherokee Purple, one of the only known ‘black’ or deep rose colored tomatoes; the Green Zebra, a small green tomato with either yellow or reddish stripes depending on when you pick them. They are rather tart and are often man-made therefore they can not be an heirloom tomato, although it is often categorized as one.

Black cherry tomatoes are tomatoes everyone should be familiar with. They are the smallest of the heirloom tomatoes and come in a cluster on a fine like grapes and are sometimes referred to as grape tomatoes.

The Hillbilly and the Big Rainbow are similar heirloom tomatoes because of their yellow, large fruit with red swirls of color; however their origin is unknown so verification into the heirloom society is iffy at best. One of the best stories behind an heirloom tomato is the Mortgage Lifter tomato. A man by the name of “Radiator Charlie” who owned a radiator business during the Great Depression lost his business and decided to breed his best four tomato plants into one giant tomato that tasted better and sweeter than any one of them individually. He was able to come up with the best tomatoes and advertised that they could easily feed a family of six. He began selling his plants for a dollar a piece and that was when a dollar was a dollar and so after four years, he was able to pay off his mortgage. People began calling the large tomatoes the Mortgage Lifter after that and “Radiator Charlie” was able to retire after a few more years.

Growing Tomatoes

Most of the tomatoes grown in Britain are grown in greenhouses yet there are several excellent varieties that are specifically for growing outside. The tomato plant requires a growing temperature of 60 F. In some of our cold, wet, summers especially the ones we frequently have in the North, the crops grown outside are often disappointing and can be attacked by potato blight disease. Without sunshine the fruits will not ripen but even without a greenhouse you can still grow beautiful, flavoursome tomatoes using one of the portable mini poly-houses.

This type is of simple construction, a tubular metal frame that can be easily fitted together and therefore can be just as easily dismantled when not in use. The plastic cover fits snugly over the frame and is ideal for giving a little warmth and protection when the weather is poor.

If you are handy you can construct a similar type of frame from timber and this with a plastic sheeting cover will work almost as well.

Tomato plants can be purchased during May or you can raise your own from seed under glass. This will give you the opportunity to experiment and try some of the newer or very-coloured tomatoes that the seed companies have on offer. Those, which you intend to grow outside, must be one of the outside growing varieties to be successful. Though seeds can be sown out-of-doors it is generally not a very satisfactory process unless they have shelter and warmth. If you purchase plants make sure that they are well-hardened, sturdy, dark green specimens.

Soil Preparation

Tomatoes do not mind if the soil is light or heavy but it must contain plenty of organic manure. If you are growing the tomatoes outside they must be in a warm, sheltered position in a sunny aspect. In April add plenty of well-rotted compost or manure to the soil.

Sowing in the Greenhouse

The seed can be sown anytime between February and May they should be 2 in. apart in trays of seed compost covered with a sheet of glass until germination. Give as much light as possible, after about 28 days, pot up into 3 in. pots in John Innes potting compost No.1.

Planting Out in the Greenhouse

In the greenhouse the plants may be grown in the border soil, or in pots of good compost. A popular method of growing these plants is to place pots that have had their bottoms removed onto 6 in. deep bed of ashes or coarse sand and shingle. The ashes or single will hold a large quantity of water so the plants do not suffer
