They bloom in the summer.<br>\nIn the open ground, Oleander likes a sheltered spot in full sun. Preferably plant a hardy variety in the open ground or provide the Oleander with a solid cover against frost. Oleanders like a calcareous and nutrient-rich soil with a neutral <a title=\"Glossary\" href=\"https:\/\/plantenplagen.nl\/dossiers\/woordenlijst\/\" target=\"_blank\" rel=\"noopener noreferrer\">pH<\/a> (7). They do not feel at home in acidic soil and on peat or peaty soil. Fertilize Oleanders in the spring.<br>\nIn spring, prune dead and frost-damaged branches to just above the ground. Overgrown branches can be pruned back to about half their length in September after flowering.<br>\nThe soil in which the plant stands should be slightly moist. Prevent Oleanders from drying out during dry periods, water regularly.[\/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;]Red, yellow or brown spots develop on the leaves; the leaves eventually die.
