I would like to the name of a weed and how to eradicate it.
I live in Brisbane and I have a weed that has been sprouting in my yard and more recently in my garden. It is a thin stem with the seeds on the top of the stem. It's very easy to pull out; however, the seeds on the top are very sensitive to movement and pop, thereby spreading the weed. Do you know what it is and how I can get rid of it? Is there a spray that will kill it but not kill plants?
I think you are talking about Hairy Bittercress
Preventing Hairy Bittercress in the Garden
This pesky weed is small enough to hide among your landscape plants. Its extensive seed expulsion means that just one or two weeds can spread quickly through the garden in spring. Early control for hairy bittergrass is essential to protect the rest of the landscape from an infestation.
Prevent invasions into turf areas by encouraging good grass growth. The weeds easily infest thin or patchy areas. Apply several inches of mulch around landscape plants to help prevent seeds from getting a foothold in your soil. You can find more information on this site under Weed Control and Identification. Hope this helps.
