Question
I have a blue agave planted outside my home in a rock bed.  Weeds continually pop up.  Can I put weed-killer down around the blue agave without it hurting the plant?
Thanks for your help.

Answer
I wouldn't.  You can read the label and see what the manufacturer says, but agave have some shallow roots.  I would hand weed around it and give it a gravel mulch with peas stone or quartz.  You can layer the gravel 2-3 in. thick which will cut down on weeds dramatically and will highlight the plant as well.  You will see a weed pop up her and there, but they're easy to spot and pull before they spread.
