Weeds and plant debris harbor overwintering insects, diseases, and viruses. Here is a short to do list:<\/p>\n<ul>\n<li>Remove all\u00a0weeds and plant debris. Aphids, spider mites, thrips and whiteflies may move onto newly\u00a0planted crops from weeds.<\/li>\n<li>Clean work\u00a0areas and production surfaces first by sweeping and\/or hosing down.<\/li>\n<li>Clean up old\u00a0growing medium left on benches and floors to reduce breeding areas for\u00a0pests like fungus gnats, shoreflies and Western flower thrips.<\/li>\n<li>Disinfect to kill all pathogenic organisms utilizing a number of commercial\u00a0disinfectants, including hydrogen dioxide and quaternary ammonium compounds.\u00a0Scrub up or dispose of\u00a0previously used plastic pots and trays, tools and\u00a0equipment.<\/li>\n<li>Keep hose nozzles off floor.<\/li>\n<\/ul>\n<p><b>#3 &#8211; <\/b>Inspect <span style=\"text-decoration: underline;\">all<\/span> new incoming plants, even\u00a0newly purchased plants and cuttings. Outside overwintering plants\u00a0may have\u00a0insects and scales and mites on them.<\/p>\n<p>Most pre-emergent\u00a0herbicides are NOT labeled for use in greenhouses; they may cause\u00a0significant plant injury. Roundup\u00ae herbicide is labeled for application to greenhouse floors. Landscape fabric for weed prevention and new gravel on floors and under\u00a0benches reduces weed populations. Follow the herbicide label for proper application rates and restrictions to\u00a0prevent spray drift and volatility that could injure plants.<\/p>\n<p>When potting up: inspect and discard plants with\u00a0brown unhealthy roots; swellings on the roots (root knot nematode); abnormal leaf vein discoloration (foliar nematodes); mosaic ring spots, dark lines and rings (viruses); and chlorotic leaves (nutritional disorders).<\/p>\n<p><b>In summary<\/b> start out clean and make all efforts to stay clean.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u00a0 Before starting\u00a0new spring vegetable and flower plants, first take some time to make sure that the greenhouse is clean.
