crowrita1 said: Well, that depends on how "green" you are ! The old "hunt & squish" method works....if you catch them early, and get them all. next up, would be nematodes...you put them in the soil, and the little guys eat the borers. What I use is a chemical......Bayer Long Season Grub Control.....it contains a systemic poison ( the plant actually takes up the chemical, through the roots, and, in effect, becomes "poison" itself), which can be found as either a Liquid concentrate, or a granular. (I think the granular may have some fertilizer added, as well )
But a sharp eye for "borer sign" on the leaves, and a good "squish" is hard to beat !
