By definition a weed is any plant that you don\u2019t want in\u00a0your garden. Herbicides are vegetation killers and\u00a0 classified as a pesticide that kills weeds. When used incorrectly,\u00a0herbicides may\u00a0injure\u00a0good plants as well. Always read and understand the package directions before using. <\/strong><\/p>\n

In a lawn or garden, you\u00a0may be\u00a0trying to control (manage) three<\/span> different kinds of weeds: grasses, broadleaves, and sedges. Broadleaf weeds including dandelions, spotted spurge, buckthorn, purslanes and thistles. Fall and late winter (before new leaves emerge) are safe times to spray broadleaf herbicides. Most deciduous shrubs and trees are shedding their leaves and are less susceptible to the spray drift. Some herbicides are labelled to kill\u00a0sedges only or grassy weeds only such as yellow nutsedge, dallisgrass, or quackgrass.<\/p>\n

Check the weather forecast before spraying herbicides. Avoid spraying on windy days or on hot days over 85 \u00b0F as herbicides may drift or volatilize, injuring nearby garden plants.\u00a0Hot summer temperatures increase\u00a0chances of lawn injury from herbicides.\u00a0It\u00a0should not rain for 8-12 hours following an application.<\/p>\n

For a\u00a0herbicide to work, outside temperatures need to be 60 \u00b0F and higher\u00a0over a 6 hour interval for\u00a0contact broadleaf herbicide spray to be adsorbed inside the plant. Regardless the time of the year, weeds need to be actively growing for herbicides to work.<\/p>\n

Don’t mow a few days before and 2-3 days following an application. Greater leaf coverage is important here. Don’t spray newly seeded areas and wait 3-4 mowings before treating a new lawn with additional herbicides.<\/p>\n

Spring and early summer herbicide applications do not control perennial and woody vegetation such as brambles, poison ivy, and invasive species. Wait until mid-summer to start tackling these tough weeds; multiple applications are usually necessary.<\/p>\n

Heavy weed invasion in lawns may be evidence of poor mowing practices, low soil fertility, or too much shade which favors the weeds more than the grass. Presence of knotweed and spotted spurge\u00a0usually indicates bad soil compaction.<\/p>\n","protected":false},"excerpt":{"rendered":"
