Jim from Cumming, Ga writes,

Round Up Pro is not working on my ivy. Suggestions?


It has been very chilly out in GA lately, much too chilly for a product that must be translocated through a plant to work. Glyphosate based products work systemically on plants. When plants are cold or water stressed glyphosate based products will not work well on them because they are not actively growing at that time so they will not move the product through the plant. You should wait until the weather starts to have daily average temps in the 60's for the best results.
