The region enjoyed warmer than average temperatures last week and into the weekend before things cooled off on Monday and now remain seasonal. While warmups like we saw last week are not uncommon in March, the extended 5- to 6-day duration of warm weather has Forsythia in full bloom across much of the region. What […]
It finally feels like summer in New Jersey. Rain, humidity, and warmer temperatures, especially at night, mean that warm-season weeds are growing quickly. Of particular concern are summer annuals like crabgrass, goosegrass, and spurges. Yellow nutsedge and false-green kyllinga are warm-season perennials are also enjoying the weather. These weeds are now growing more quickly than […]
Now is the ideal time to control yellow nutsedge (Cyperus esculentus). This plant is a perennial that grows best during the heat of summer and survives the winter through underground tubers. While the drought may have limited nutsedge emergence in unirrigated areas, it is visible and rapidly growing in irrigated beds and lawns. Yellow nutsedge […]
With warmer weather comes plant growth. The most conspicuous plants in the lawn and landscape right now are winter annuals such as hairy bittercress (Cardamine hirsuta), henbit (Lamium amplexicaule), purple deadnettle (Lamium purpureum), and chickweeds (Stellaria media and Cerastium fontanum ssp. vulgare), to name a few. In lawns, these winter annuals are typically found in […]
Japanese stiltgrass (Microstegium vimineum) is a C4 summer annual grassy weed commonly invasive to forests. It can be problematic in lawns. Often it is problematic in shaded areas adjacent to an infested forest. But we have observed infestations in full sun turfgrass areas where you would normally expect crabgrass to be the predominant summer annual. […]
Conditions for good annual bluegrass growth have returned. Whether you adore or despise Poa annua, consider completing a survey which will allow us to collect valuable insights regarding the turf industry and opinions about managing this pesky grass. The results of this survey will inform a national project team of turfgrass weed scientists working to […]
