European spruce is native to mountainous areas of Europe. Norway spruce is widespread in the UK, having been planted for forestry in the 1800s.<br>\nThe Norway spruce as a Christmas <wbr><\/wbr>tree averages one and a half meters in height. Christmas tree producers harvest seeds from popular pines, and after planting they can take up to four years to reach a height of just 25 cm. From this point, the saplings are then planted in fields and allowed to grow until harvested. A lot of the trees are delivered with root balls.<br>\nChristmas trees with root balls are best treated like a very large houseplant. Plant the tree in a large pot and keep the root ball moist with water enriched with liquid plant food.<br>\nIf the intention is to plant the Christmas <wbr><\/wbr>tree later in the garden, the top branch for the peak should not be cut off.<br>\nPlant the tree in the garden when it is not freezing and let the tree get used to the outside temperature slowly first in an unheated garage or shed.[\/vc_column_text][\/vc_column][\/vc_row][vc_row equal_height=&rdquo;yes&rdquo;][vc_column width=&rdquo;1\/3&Prime;][vc_custom_heading text=&rdquo;Bugs&rdquo; font_container=&rdquo;tag:h4|text_align:center|color:%23ffffff&rdquo; google_fonts=&rdquo;font_family:Lato%3A100%2C100italic%2C300%2C300italic%2Cregular%2Citalic%2C700%2C700italic%2C900%2C900italic|font_style:400%20regular%3A400%3Anormal&rdquo; css=&rdquo;.vc_custom_1532164328547{background-color: #585858 !important;}&rdquo;][vc_column_text el_class=&rdquo;entrytxt&rdquo;]<\/p>\n<figure id=\"attachment_6471\" aria-describedby=\"caption-attachment-6471\" style=\"width: 375px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/plantenplagen.nl\/wp-content\/uploads\/Bruinwordend_sparretje.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-6471\" src=\"https:\/\/plantenplagen.nl\/wp-content\/uploads\/Bruinwordend_sparretje-375x500.jpg\" alt=\"recognize cause brown needles spruce\" width=\"375\" height=\"500\" srcset=\"https:\/\/www.plantenplagen.nl\/wp-content\/uploads\/Bruinwordend_sparretje-375x500.jpg 375w, https:\/\/www.plantenplagen.nl\/wp-content\/uploads\/Bruinwordend_sparretje.jpg 720w\" sizes=\"auto, (max-width: 375px) 100vw, 375px\"><\/a><figcaption id=\"caption-attachment-6471\" class=\"wp-caption-text\">Dwarf alberta Spruce (Picea glauca &lsquo;Conica&rsquo;) turns brown on one side, photo: Benny Demandt<\/figcaption><\/figure>\n<p>Spruce turns brown on shady sides, sometimes <a href=\"https:\/\/www.plantenplagen.nl\/en\/plantenplagen\/spider-mites\/\" target=\"_blank\" title=\"[vc_row][vc_column][vc_column_text]See Red spider mite[\/vc_column_text][\/vc_column][\/vc_row]\" class=\"encyclopedia\">spider mites<\/a> appear on the branches and minute black <a href=\"https:\/\/www.plantenplagen.nl\/en\/plantenplagen\/mites\/\" target=\"_blank\" title='[vc_row][vc_column][vc_column_text css=\"\"]Mites are small, often hard to see, arachnids that can have different colors, including red, green and brown.
