Poinsettias belong in southern Mexico and the countries of central America, where they can grow five meters tall.<br>\nThe red colored leaves are the bracts. Pointsettias bloom with inconspicuous green or yellow flowers in the center of the bracts.<\/p>\n<p><em>Location:<\/em> Pointsettias need a daily dose of sun (at least five hours, to be exact), so put them in front of a south-facing window. Prevent the leaf from touching the cold window: cold affects the leaf. Also, do not put the plants in a draft, which prevents premature leaf fall. Provide an ambient temperature of around 21&ordm;C, in which they thrive best. In cooler environments (15&ordm;C and below), the risk of root rot increases.<br>\n<em>Soil:<\/em> potting soil, mixed with some moss or peat to retain water.<br>\n<em>Watering:<\/em> The soil should not dry out, Pointsettias like a slightly moist soil. Too wet is not good either, and the roots will rot away. So make sure excess water can drain: place the potted plant in an ornamental pot with some gravel at the bottom.<br>\n<em>Keep:<\/em> After the leaves have fallen off, put the plant in a cool and dark place (<u>+<\/u>15&ordm;C) and do not water again. The plant goes dormant; put it back in a warm environment after two months and the Poinsettia will sprout again. Start watering; repot the plant if necessary.[\/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;]<em>Glasshouse cultivation:<\/em> leaves turn yellow and bumpy; eggs on underside of leaves: <a href=\"https:\/\/www.plantenplagen.nl\/en\/plantenplagen\/greenhouse-whitefly\/\" target=\"_blank\" title='[vc_row][vc_column width=\"2\/3\"][vc_column_text el_id=\"topentry\" el_class=\"topentry\"]Greenhouse whitefly, this snow-white aphid lays its eggs on the underside of leaves.
