The 'Sibirskie Ogni' watermelon variety is an early-maturing and high-yielding variety, ideal for growing in open ground and under plastic coverings. The plant is semi-vine, reaching a height of about 2.5 meters, with the main stem length being approximately 250 cm. The fruits have an oval shape with dark green rind and barely noticeable thin stripes. The weight of watermelons ranges from 2 to 5 kilograms, and the flesh features a rich red-magenta color, grainy texture, sweet and juicy taste. 'Sibirskie Ogni' is characterized by high resistance to cold, fusarium, drought, and low temperatures, making this variety particularly valuable for regions with short summers. Sugar content in the fruits reaches 7.3%, ensuring their pleasant sweet taste. From germination to harvest takes from 78 to 95 days, allowing for an early harvest. For successful growing, it is recommended to sow seeds into open soil at the end of May with daytime temperatures of 25–30 °C and nighttime 18–20 °C. The soil requires fertilization, and watering should be moderate, as the root system can cope independently with moisture deficiency. Loosening the soil after watering is beneficial to improve aeration. The yield per plant ranges from 9 to 12 kilograms. To ensure even ripening of the fruits, it is recommended to turn them over periodically. The 'Sibirskie Ogni' watermelon is versatile in use and suitable both for fresh consumption and for storage and transportation. Thanks to its adaptive qualities and unpretentiousness in care, this variety will be an excellent choice for gardeners wishing to obtain tasty and juicy watermelons without significant time and effort expenditure.
