Three basic types of turfgrass weeds

The basic definition of a weed is any plant growing in a place that it is not wanted.

The three basic types of weeds found in managed stands of turfgrass are grassy weeds, grass-like weeds and broadleaf weeds.

1). Grassy Weed (Creeping Bentgrass, Quack Grass, Orchard Grass, Crab Grass, Nimblewill, etc.): Similar growth habit as desirable turfgrass. Grassy weeds are monocots, meaning they produce leaves one at a time.  Leaves are usually narrow and veins within the leaves run parallel to one another.

2). Grasslike weed (Yellow Nutsedge and Wild Garlic): Are not true grasses, but belong to the sedge and garlic families. From afar look similar to grasses, however sedges have triangular stems and develop from nutlets.  Wild garlic leaves are hollow.

3). Broadleaf weed (Dandelion, Plantain, Clover, Thistle, Spurge, Violet, Creeping Charlie, etc.): Have net-veined leaves that are normally wider than grass leaves.  Broadleaf weeds are dicots, meaning they produce leaves in pairs.  Usually color and flowers make broadleaf weeds very easy to identify.

Only after unwanted weeds have been properly identified can a suitable control plan be implemented.  Please contact Pacocha Landscaping Services, Inc. with any weed identification challenge or control requests you may have.

Yellow Nutsedge: The problem “grass like” weed that will not leave your lawn without a fight!

If there is one persistent type of unwanted vegetation that is very difficult to control in most lawns it has to be the “grass like” weed named yellow nutsedgePacocha - Yellow Nutsedge 1 (aka yellow nutgrass).  This weed makes itself visible from mid to late summer and tends to love sun exposed wet soil lawn areas.  Yellow nutsedge is a warm season perennial plant that grows from underground tubers (nutlets) and spreads via underground horizontal creeping stems called rhizomes.  These underground tubers can easily survive many years in the upper foot of soil if negative site conditions are left unchanged.  Pacocha - Nutsedge DiagramEven though yellow nutsedge plants resembles turfgrass from afar, a closer look reveals the truth about this stubborn “grass like” weed.  The leaves of the nut sedge plant are stiffer and thicker than most grasses, are V-shaped (cross section) and grow in sets of three from the base.  Yellow nutsedge can be controlled non-chemically and chemically.  The easiest way to eradicate small colonies of yellow nutsedge is to maintain a thick lawn and simply pull the nutsedge plant out of the ground as soon as you see it.  Special care should be taken to also remove the underground tubers/nutlets (if possible) for best long term control.  Another common non-chemical way to eradicate yellow nutsedge is to improve the drainage of the effected turf grass area.  Since yellow nutsedge loves wet moist soil, a simple drainage improvement or reduction in irrigation can eliminate this particular weeds ability to flourish.  The final way to control yellow nut sedge is chemically.  Pacocha - Yellow Nutsedge 3It is very common to require multiple herbicide applications over many growing seasons to achieve desirable results.  Please contact Pacocha Landscaping Services, Inc. to evaluate the overall condition of your lawn and to discuss the possible need for chemical yellow nutsedge control.  Thank you for your time and we look forward to being of assistance to you!
