It is frost-hardy and many varieties are self-fertile, so they crop without the need for a pollinator. Below is a practical guide from the Drzewka Kusek nursery.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-sour-cherry-seedlings-the-most-popular-varieties\">Sour cherry seedlings \u2013 the most popular varieties<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>\u0141ut\u00f3wka<\/strong> \u2013 a classic, tart and productive variety; excellent for preserves, partly self-fertile.<\/li>\n\n\n\n<li><strong>Kelleris<\/strong> \u2013 frost-hardy, self-fertile and productive; tasty, dark fruit.<\/li>\n\n\n\n<li><strong>Nefris<\/strong> \u2013 self-fertile and productive; dark fruit good for juice and preserves.<\/li>\n\n\n\n<li><strong>Debreceni (Debreczy\u0144ska)<\/strong> \u2013 sweet-and-sour, productive, with dessert qualities.<\/li>\n\n\n\n<li><strong>Ujfehertoi F\u00fcrt\u00f6s<\/strong> \u2013 Hungarian, self-fertile, with dark, sizeable fruit.<\/li>\n\n\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Planning a planting?

The choice of rootstock determines vigour:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Mahaleb cherry \u2013 vigorous growth and a deep root system; tolerates drier, lighter soils.<\/li>\n\n\n\n<li>Wild (bird) cherry seedling \u2013 vigorous growth, giving sizeable trees.<\/li>\n\n\n\n<li>Dwarfing rootstocks (Gisela type) \u2013 weaker growth and earlier cropping; for smaller gardens.<\/li>\n\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-fertilising-sour-cherries\">Fertilising sour cherries \u2013 what is worth knowing?<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In spring \u2013 nitrogen fertilisers supporting growth and fruit set.<\/li>\n\n\n\n<li>In summer and autumn \u2013 potassium and phosphorus improving fruit flavour and the tree&#8217;s health.<\/li>\n\n\n\n<li>It is worth using compost or manure and keeping the soil slightly acidic.<\/li>\n\n\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-pruning-sour-cherries\">Pruning sour cherries \u2013 how and when?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Sour cherries fruit on spurs and one-year-old shoots.
