Hello: Asiatic day weeds (leaf looks similar to wandering jew and has small blue flower with yellow center) are a yearly and never-ending problem in my flower bed. What do you suggest to get rid of it? As fast as I pull them, they return. I've tried Roundup Precision Gel to no avail. Rather than spend time, energy and money on treating these pesky weeds, is there merit in totally removing the garden bed soil and replacing with fresh soil? Thank you for your advice and help. L. Wilkins (Mrs.)
Asiatic dayflower is actually an annual but prolifically self-sows. In addition, dropped seed remains viable in the soil for up to 4 years. So pulling frequently for 4 years, making sure you never allow it to go to seed should clear it up. I've hand removed it and found roots 4 inches down in loose soil. If you have clay, it is harder to free it without loosing bits to a clump of clay. Triclopyr, 2-4D and Dicamba are supposedly effective but it won't affect the dropped seed that lingers in the soil.
How do I best care for it?
Some people keep it in the yard for the blue flower. It is similar to the houseplant wandering jew but the dayflower leaves are not colorful
It looks like the summer annual Asiatic Dayflower (Commelina communis), which is generally considered a weed. Did you dig it from the garden last fall?
They can be very invasive in the garden and are best removed by digging all the root. However, they produce a small blue flower that is pretty.
I got it from my cousin, who got it from her friend who seems to have a green house. So I’m nurturing a weed? Lol
