Current dry weather has preempted most normal winter weed germination and growth while prolonged periods of dry soil has caused some early weeds to desiccate and die. In most tree and vine herbicide trials conducted so far this winter—the...

Onionweed (Asphodelus fistulosus) is an attractive but very difficult to control weed that is relatively common along highways, some irrigation right of ways and other areas in Southern California.

Once you learn to recognize it, it is easy to spot in spring and summer, especially along interstate 5 from La Jolla and on north at least as far as San Luis Obispo County.

However, to be effective the herbicide needs to be where the root radicle of the seeds are so it either has to be incorporated mechanically or moved into the soil through rainfall or irrigation. The commonly accepted term for this is “activation”.
