Sow in February under glass, mid-April to late June in open ground in final location. Harvest fall and winter. Brussels sprouts are hardy and become less bitter after frost. You can top Brussels for a slightly earlier harvest. Growing Brussels under insect netting keeps many pests away.
\nKeep Brussels sprouts weed-free. It is not necessary to remove the leaves from the plant; it does not increase yield. After harvest, the stumps can be thrown away (organic waste container); they are so hard that they are difficult to digest. This makes them unsuitable for the compost heap.[\/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”]<\/p>\n

Initially white or purple spots on malformed leaves (curled, bumpy), then the plants are colonized by ap<\/wbr>hids: Cabbage aphid (Brevicoryne brassicae)<\/em>. A greasy layer sometimes forms on the Brussels sprouts.<\/p>\n

White flies colonize the underside of the leaf. They feed on leaf sap (mesophyll) and secrete honeydew<\/a>: Cabbage whitefly<\/a> (Aleyrodes proletella)<\/em>. Sooty mold<\/a> then forms on the honeydew.<\/p>\n
