Tomato 'Arancia'

Those who love colourful bright coloured tomatoes will definitely like Tomato 'Arancia'. A beautifully rounded, orange-yellow tomato with a remarkably sweet taste, this is a commercial variety with Polish origins that is proving popular in western Europe. Famously cold, drought and disease resistant the plants reliably bears fruit steadily throughout the season .

Tomato 'Arancia' is known as Zloty Ozarowski, or Golden Ozharovsky in Poland, this indeterminate variety produces beautiful golden, honey coloured rounded fruit. The plants grows to around 1.8m tall and require pinching and staking. They plants tend to become overloaded with the weight of the fruits and definitely need good support. Recommended for growing in the open field and in greenhouses and are resistant to tobacco mosaic virus. The maturation period is medium-early, 95 to 105 days from germination. Harvest from the second week of July until September.
The plants produce medium to large fruit with an average weight of around 175 grams, a large salad or small beefsteak type of tomato that is sometimes slightly flattened. Golden, deep honey coloured, the flesh is soft and fleshy, with a sweet and intense flavour. The fruits can be used for canning but are at their absolute best when eaten fresh as a snack or used as a splash of colour in a salad.

Timing:
As they cannot tolerate any degree of frost the timing for sowing and planting outside is key to successfully growing tomatoes. Where the seeds are sown under cover or indoors, aim to sow the seeds so that they reach the stage to be transplanted outside three weeks after the last frost date. Tomato plants take roughly seven weeks from sowing to reach the transplanting stage. For example, if your last frost date is early May, the seeds should be planted in early April to allow transplanting at the end of May.

Position:
Tomatoes require a full sun position. Two or three weeks before planting, dig the soil over and incorporate as much organic matter as possible. The best soil used for containers is half potting compost and half a soil-based type loam: this gives some weight to the soil.

Sowing:
Plant about 3mm (1/8in) deep, in small pots using seed starting compost. Water lightly and keep consistently moist until germination occurs. Tomato seeds usually germinate within 5 to 10 days when kept in the optimum temperature range of 21 to 27°C (70 to 80°F). As soon as they emerge, place them in a location that receives a lot of light and a cooler temperature (60 to 70°F); a south-facing window should work.

Transplanting:
When the plants develop their first true leaves, and before they become root bound, they should be transplanted into larger into 20cm (4in) pots.
Young plants are very tender and susceptible to frost damage, as well as sunburn. I protect my young plants by placing a large plastic milk jug, with the bottom removed, to form a miniature greenhouse.
Depending on the components of your compost, you may need to begin fertilising. If you do fertilise, do it very, very sparingly with a weak dilution.
Transplant into their final positions when they are about 15cm (6in) high. Two to three weeks prior to this, the plants should be hardened off.

Planting:
Just before transplanting the tomato plants to their final position drive a strong stake into the ground 5cm (2in) from the planting position. The stake should be at least 30cm (1ft) deep in the ground and 1.2m (4ft) above ground level - the further into the ground the better the support. As the plant grows, tie in the main stem to the support stake - check previous ties to ensure that they do not cut into the stem as the plant grows.
Dig a hole 45cm (18in) apart in the bed to the same depth as the pot and water if conditions are at all dry. Ease the plant out of the pot, keeping the root ball as undisturbed as far as possible. Place it in the hole and fill around the plant with soil. The soil should be a little higher than it was in the pot. Loosely tie the plant's stem to the support stake using soft garden twine –allow some slack for future growth.

Cultivation:
A constant supply of moisture is essential, dry periods significantly increase the risk of the fruit splitting. Feed with a liquid tomato fertiliser (high in potash) starting when the first fruits start to form, and every two or three weeks up to the end of August. In September, feed with a general fertiliser (higher in nitrogen) in order to help the plant support it's foliage.
Over watering may help to produce larger fruit, but flavour may be reduced. Additionally, splitting and cracking can result from uneven and excessive watering.

Pruning:
When the first fruits begin to form, pinch out the side shoots between the main stem. Also remove lower leaves which show any signs of yellowing to avoid infection.

Harvesting:
Pick as soon as the fruits are ripe, this also encourages the production of more fruit. Cherry tomatoes are usually tender-firm and thin-skinned, the skins of the fruit will split if watering regimes are erratic, or if the fruits are not harvesting promptly and left too long on the vine. At the end of the season, harvest all the fruit as soon as frost threatens and ripen on a window sill.
Once harvested, store at room temperature, as anything below 10°C (50°F) destroys the enzyme that gives tomatoes their flavour.

Origin:
The tomato originates from South America's western coast. They are native to the Andes region of Chile, Colombia, Bolivia, and Peru, however they are believed to have been domesticated in Mexico.
It was in the early 1500s that returning Spanish colonists first introduced tomatoes to Europe. However, in North America, tomatoes were not widely embraced until the early 1800s. Despite being grown and used by pockets of colonial Americans, they were thought to be toxic as they are in the Solanaceae family, which includes deadly nightshades and other poisonous plants. This was disproved publicly in 1820 when Colonel Robert Gibbon Johnson ate a tomato on the courthouse steps of Salem, New Jersey.
The first traces of its use as a food date back to the first half of the 18th century. Originally believed to be poisonous when introduced into Europe and was used solely as an ornamental plant during the 16th and 17th centuries. Around the same time that the myth of tomatoes being poisonous was dispelled, people in France started to believe that the tomato was an aphrodisiac, and began calling it 'pomme d'amour', or 'love apple.'
There is no evidence that points to a specific time and place of discovery for the first yellow cherry tomato, but it is known that it was a natural occurring mutation found on a red cherry tomato plant. A recessive gene contained in the tomato’s genetic makeup.
This gene causes flavonoids in the skin and increases the level of yellow carotenoids, carotene and beta-carotene, the pigment which results in the yellow complexion. This single mutation is responsible for the evolution of Yellow cherry tomatoes and the many varieties on the market today.

Nomenclature:
Botanically, the tomato is a fruit, but in 1883 the U.S. Supreme Court ruled that the tomato was legally a vegetable because of the way it was commonly used. Tomatoes are among the most common plants grown in home gardens.
The botanical classification of the tomato has had an interesting history, and debate over the scientific name continues today. The tomato was first placed in the genus Solanum, and identified as Solanum lycopersicum under the methodology of Carl Linnaeus, who developed the binomial system of naming plants and outlined it in his 1753 publication, 'Species Plantarum'. This designation was then changed to Lycopersicon esculentum, the term Lycopersicon deriving from the Greek word meaning 'wolf peach,' and esculentum simply meaning edible. However, current phylogenetic methods have shown the tomato to be situated firmly within the genus Solanum, and after years of preference for the name Lycopersicon esculentum, strong molecular DNA evidence is promoting the return to Linnaeus' original classification, Solanum lycopersicum.
Cherry tomatoes, in particular, are then more specifically called Lycopersicon esculentum var. cerasiforme.

Tomato Sizes:

• The very smallest of cherry tomatoes are usually classified as Currant or small Cherry tomatoes. Weighing 7 to 14 grams and measuring 1.5 to 2.5 cm in diameter.

• A Cherry, Cocktail, Fig or Pear tomato usually weighs between 28 and 57 grams, they are the smallest types of cherry types of tomatoes that are generally available. Most cherry tomatoes weigh in at around 28 grams, with a diameter of about 2.5cm.

• A small to medium sized tomato, the Grape or the small Plum type usually weigh between 28 to 84 grams. This makes them about the same size or slightly larger than a regular cherry tomato.

• A Roma or other paste types of tomato weighs between 57 and 142 grams. This makes them somewhat larger than cherry or grape tomatoes.

• A medium to large, traditional Salad or Slicing type of tomato weighs between 84 to 142 grams and measure 10 to 12cm in diameter.

• The Beefsteak tomatoes can weigh anything between 225 to 1800 grams. A Large Beefsteak weighs 225 to 340 grams and measures 12 to 20 cm in diameter, an Extra Large Beefsteak weighs 340 to 510 grams and measures 20 to 25cm, while Giant Beefsteak tomatoes can reach huge proportions. They weigh in excess of 510 grams and measure over 25cm in diameter.
