Q

How do I get rid of wild morning glory?

Answer(s)

A

This weed is correctly called field bindweed.  It is a very difficult and persistent problem.  The plant propagates by seed and underground rhizomes.  Early “weeding” of young plants reduces and sometimes eliminates their growth.  However, established plants with a deep root system are extremely hard to control and a broadleaf weed killer should be applied during the blooming season or in the fall after the first frost. 
Recommendation:  Grow a vigorous lawn to compete against bindweed, or apply mulch 3 inches deep over it.  Occasionally pull sprouts or spot-treat with perennial-rate glyphosate.
