Not to be confused with Corn stover that is widely grown as animal feed. The plant produces both female and male flowers. The female flowers develop into the corn cobs. In winter, the corn bed is prepared by applying large amounts of manure. Sweetcorn likes a slightly acidic soil (pH 5.5). Peat makes the soil a little more acidic. Sweetcorn likes heat: pre-sow in April in the warm greenhouse or on the windowsill. Sowing in open ground cannot be done until mid-May. In addition to sweetcorn, seeds for popcorn are also available.[\/vc_column_text][\/vc_column][\/vc_row][vc_row equal_height=”yes”][vc_column width=”1\/3″][vc_custom_heading text=”Bugs” font_container=”tag:h4|text_align:center|color:%23ffffff” google_fonts=”font_family:Lato%3A100%2C100italic%2C300%2C300italic%2Cregular%2Citalic%2C700%2C700italic%2C900%2C900italic|font_style:400%20regular%3A400%3Anormal” css=”.vc_custom_1532164328547{background-color: #585858 !important;}”][vc_column_text el_class=”entrytxt”]Growth tips are gnawed, more side shoots appear and a thickened foot: frit fly<\/a> (Oscinella frit)<\/em>.<\/p>\n
