Mulberry weed growing under my miniature gardenias, and it is really too much to pick. I need a product that will kill the mulberry weed without harming gardenias.
Mulberry weed is an annual weed and can be prevented with the proper timing of pre-emergent chemical. The best pre-emergent for broadleaf weeds is dithiopyr such as Dimension 2EW. It should be applied in late March and again in mid-May. If you have a huge mulberry weed population, you can make a third application in early July. Spot treating with something like Hi-Yield 2,4-D and/or a glyphosate based product will kill mulberry weed but care should be taken to avoid contact/drift with the gardenias as they could be injured as well. Key is to kill or pull the weed before it drops the seeds, which the plant does a few weeks after germination. There is an article by UGA here that might help.
