The plant is indeterminate, intended for growing in open ground, height 5-6 feet (1.5-1.8 m). Characterized by excellent fruit set in greenhouses. An extremely heavy yielder, the plant is literally showered with red, elongated, eggplant-shaped fruits weighing up to 10.5 oz (300 g). The fruits are very uniform, dense, tasty, perfect for canning, and store well. Depending on growing conditions and soil fertility, yields can reach 2 to 3 buckets per plant. The variety was acclimatized in the Western Siberian region. Recommended planting density is 3 plants per square meter (approx 10 sq ft).<\/p>\n<p>Photo credit: Ninu<\/p>\n<p><a href=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/galleries\/8\/1310-150214101404.jpeg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/galleries\/8\/thumb_1310-150214101404.jpeg\" alt=\"Kenigsberg tomatoes ripening on the vine\" width=\"120\" height=\"160\" \/><\/a><br \/>\n<a href=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/galleries\/8\/1310-150214101332.jpeg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/galleries\/8\/thumb_1310-150214101332.jpeg\" alt=\"Red elongated Kenigsberg tomatoes\" width=\"160\" height=\"120\" \/><\/a><br \/>\n<a href=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/galleries\/41\/12696-151114174302.jpeg\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.tomat-pomidor.com\/uploads\/newforum\/galleries\/41\/thumb_12696-151114174302.jpeg\" alt=\"Harvested Kenigsberg paste tomatoes\" width=\"120\" height=\"160\" \/><\/a><\/p>\n<\/div>\n<\/div>\n<div class=\"forum-post\">\n<div class=\"author-header\">\n<div class=\"forum-avatar\">P<\/div>\n<div class=\"author-meta\">\n<div class=\"author-name\">Pani Tomat (Irina) <span class=\"author-stats\">\u2b50 Pro Grower (8,773 posts)<\/span><\/div>\n<\/div>\n<\/div>\n<div class=\"post-content\">\n<p>I grew Kenigsberg from SibSad.
