Origin and History
'Harzfeuer F1' is a hybrid variety from the former GDR and is said to come from a cross between 'Moneymaker' and 'Early Love'. In 1959 it came onto the market for the first time under the name 'Prima Vera'. However, since a variety with this name already existed and its breeders objected to the approval, breeder Dr. Finally Fabig in 1961 for the name 'Harzfeuer F1'. She is now known and loved far beyond her home in Quedlinburg.
Characteristics and taste of the ‘Harzfeuer’ tomato variety
The 'Harzfeuer F1' plants are vigorous and grow up to two meters tall. From the end of July, up to ten fruits ripen on a single panicle. The 'Harzfeuer F1' fruits are round to slightly flattened and bright red. They reach a weight of around 90 grams. Ripe 'Harzfeuer F1' have a sweet, fruity taste. The skin of the fruit is quite thin, the flesh is juicy but firm. 'Harzfeuer F1' is a hybrid variety, which can be recognized by its suffix "F1". It is therefore not a seed-resistant variety and should not be sown again from your own seeds. Because there is a good chance that the original properties of 'Harzfeuer F1' will not appear in the seedlings. So the seed for this variety has to be renewed again and againbe purchased.
Planting and caring for Harzfeuer tomatoes
The 'Harzfeuer F1' is a very robust and adaptable salad tomato. It is suitable for cultivation in greenhouses and outdoors, but also as a balcony tomato. Young plants can be planted outdoors or in tubs from mid-May, and in greenhouses from the beginning of May. As a salad tomato, the 'Harzfeuer F1' gets along well with two or three shoots. Leave two deep-seated side shoots and trim the rest. All shoots should be well supported and tied if necessary.
The use of mineral fertilizers can quickly lead to over-fertilization of resin fire tomatoes, as they tend to turn green if too much nitrogen is added. This means that the fruit does not turn red around the base of the stem, but remains yellowish-green. Organic fertilizers, on the other hand, release their nutrients slowly and gently, so there is no risk of green collars. At the beginning of June, as soon as fruit formation begins, we therefore recommend applying a primarily organic long-term fertilizer, such as our Plantura organic tomato fertilizer.
The tomato resin fire in the pot: you should pay attention to that
To keep the 'Harzfeuer F1' in a pot, fill the planter with a special soil, for example with our Plantura organic tomato and vegetable soil. It is adapted to the needs of tomatoes and other types of vegetables and is pre-fertilized accordingly. At best, place the planted pot on a warm house wall where it is protected from rain.
Harvesting and Using Resin Fire Tomatoes
As a firm salad tomato, the 'Harzfeuer F1' is particularly suitable as a snack tomato for snacks and chopped into small pieces in salads. The fruits can also be filled and gratinated in the oven.
