White Flower Challenge - Day 22

Convolvulus arvensis

Bindweed, Wild Morning Glory

Here is another weed I found in the field Friday. Although it has a pretty flower, it is generally considered one of California's worst weeds. It's habit of twining and spreading quickly builds an extensive root system which easily withstands most half-hearted weeding techniques. And the seeds can lay dormant for 50 years! So, if you have it, keep digging the roots out and if all else fails, use soil solarization to kill it.

Okay, I will be the first to ask. What is soil solarization?? I have had a long night and maybe it is obvious, but humor me please.

Isn't it funny that weeds are so hardy? And, this one does have a beautiful bloom.

The botanical name made me giggle. It sounds a bit risque. Okay, okay, maybe I am kind of goofy this morning. Just call me "Pink" punchy.

to Janet,
Soil solarization is a weed killing technique that uses plastic sheeting to "cook" the weeds, fungi, bacteria, and seeds. Basically you moisten the affected area, cover with plastic and wait 6weeks. Then remove the plastic and plant.
I've never tried it, but I have a spot where I could. I'll let you know if it works when I do.

The bloom is pretty on that invasive weed! Thanks for the definition of "soil solarization". I think my kids used that technique on a large section of our yard, years ago, with the "Slip and Slide"!
