Origin and history of the tomato
The ‘Big Rainbow’ is an old tomato variety that Dorothy Beiswenger donated to the collection of the Seed Savers Exchange Minnesota in 1983. A few years later, around 1990, the beefsteak tomato came onto the market as a variety and has been cultivated and propagated ever since. In terms of its color and size, it is reminiscent of the ‘Hillbilly’ tomato variety.
Description and taste of the Big Rainbow tomato variety
The ‘Big Rainbow’ variety produces large, slightly ribbed, and flat-round fruits. With fruits weighing up to 500 grams, it is one of the beefsteak tomatoes. The plants measure up to 180 centimeters in height and are quite hairy. The tomatoes of the ‘Big Rainbow’ reach up to 10 centimeters in diameter and inspire in summer with their yellow color and the red and orange stripes and marbling.
The fruits ripen in mid-late August, the tomato plants then bear reliably and abundantly until the end of October. The taste of the ‘Big Rainbow’ is sweet and fruity with a little acid, which makes it tolerable even for people with sensitive stomachs. The variety is solid and can therefore easily be propagated from its seeds.
Planting and caring for Big Rainbow: this is important to note
The Big Rainbow tomato is suitable for cultivation in the protected field, in the tub, and of course in the greenhouse. The young plants are planted out in the greenhouse and polytunnels for tomato cultivation from the beginning of May and placed in pots and outdoors from mid-May after the Ice Saints. For the ‘Big Rainbow’, choose the largest possible pot or a sheltered spot in the bed. We recommend filling the planter with a substrate specially adapted for tomatoes.
Organic tomato soil already contains essential nutrients that stimulate young plants to grow. Incidentally, the high compost content promotes a crumbly structure and soil organisms even on difficult garden soils. In this way, the soil can be improved over the long term and the health and yield of the vegetable plants can be increased. After planting, the Big Rainbow tomato should be watered extensively and supported, and tied with a stick.
The beefsteak tomato should only be grown with one or two shots. The pruning of the tomatoes is necessary so that fewer and stronger shoots develop that can support the high weight of the fruit. All surplus side shoots are removed regularly and can be fermented into plant-strengthening tomato manure. The procedure is the same as for nettle manure, the ratio of dilution when pouring should be 1:20. The nightshade plants are fertilized for the first time from June.

As soon as the first fruits start to grow, the tomato plant needs larger amounts of nutrients. With an organic liquid fertilizer, such as our Plantura organic tomato & vegetable fertilizer, you can simply fertilize once a week over the irrigation water. The nutrients are flushed directly to the roots and can be quickly absorbed by the plant.
