BROADLEAF WEEDS

​

The many types of broadleaf weeds that grow in Central PA germinate at different times during the season. Some are winter annuals, some are summer annuals and some are perennial broadleaf weeds.  It is best to control these weeds shortly after they emerge and are actively growing. 

Dandelion Fields

Dandelion (Taraxacum officinale)

This broadleaf weed is a perennial.  Seedlings emerge when the soil temperatures reach a consistent 50 degrees in the early spring. Dandelions prefer moist conditions and soils and thrive in weak, thin turf. They get bright yellow blossoms that grow on the end of leafless, hollow stalk that emits a white milky sap when broken.  The plant produces a puffball seed head.  The seeds are then dispersed by wind. The seeds germinate and the plants can crowd out your healthy turf.

How do you get rid of dandelions?

Dandelion Leaves

A healthy, thick lawn is a good defense against dandelions.  A comprehensive turf program for your lawn is recommended to ensure a healthy, thick lawn. The turf program should include balanced fertilizer applications and post-emergent broadleaf herbicide application.

Added organic supplement applications are recommended as they release microbes, beneficial bacteria and fungi into the soil and helps turf use the products more effectively and efficiently.  

The lawn applications alone are not the solution. Good agronomic practices also play an integral part in the control of dandelions.  As a rule, the mow height should be at 3 inches to keep the grass blades strong and healthy limiting the opportunity for dandelions to grow.

Turf Program to Combat Dandelions

  • Balanced Fertilizer

  • Post-emergent Broadleaf Application

  • Organic Supplement

  • Correct pH in soil-Liming
