Korean fir (<em>Abies koreana<\/em>) is a densely branched pyramidal evergreen tree. Growth is slow in the beginning, eventually reaching 50 feet or more in mature height. The wide 3\/4 inch long needles are dark green and glossy above and silvery on the underside. Upright purple 3-inch cones are a distinctive feature of this fir.<\/p>\n<p>&#8216;Silberlocke&#8217;, aka &#8216;Horstmann&#8217;s Silberlocke&#8217;, typically grows as a compact pyramidal shrub form, 8 to 10 feet tall in its first 10 years, eventually maturing to 18 to 20 feet tall and 12 to 18 feet wide. The needles are uniquely recurved and silvery-white beneath. Silberlocke was introduced in 1986 by German plantsman Gunter Horstmann.<\/p>\n<p>When properly sited in full sun (minimum of 6 hours) and a compost-rich, well-drained soil. It prefers a cool well-drained site (USDA hardiness zones 5 to 7) and often fails in summer heat and humidity further south. If you garden in USDA zone 7 and\/or the soil is a heavy clay loam, grow &#8216;Silberlocke&#8217; korean fir grafted onto Japanese Momi fir <em>Abies firma<\/em> rootstock.<\/p>\n<p>Silberlocke has few serious disease or pest problems. Stem cankers and Phytophthora root rot often kill most firs (<em>Abies spp.<\/em>). Generally, firs languish, if not die, in hot droughty soils and urban pollution. Maintain a 2-3 inch thick mulch layer around Silberlocke to conserve soil moisture and moderate root temperatures.<\/p>\n<p>Feed once yearly with 10-10-10 granular fertilizer in late winter or apply an acidic water-soluble product such as Miracle Gro\u2122, Jacks\u2122, or Hollytone\u2122 in spring and early summer.<\/p>\n<p>Silberlocke\u2019s silvery needle foliage and erect standing purple cones provide 4-seasons of interest. Plant availability is usually limited to specialty conifer nurseries from e-commerce. Again, specify grafted stock if you garden in zone 7.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In any season visitors to your garden should immediately take notice of \u2018Silberlocke\u2019 korean fir.
