Whats with all this Oxalis???????

Weed of Spring 2011

Oxalis – AKA Yellow Woodsorrel, is more prolific this spring than I have ever seen it.  It germinates in late March or early April and is quite resistant to most weed controls.  We have found that Fluroxpyr or Triclopyr are the best herbicides to control it.  It has a small yellow flower and is generally considered a summer annual, although, there is a perennial variety. We will control it during 2nd and 3rd apps in 2011.
