Is this a permanent fix or is it an annual application that needs applied annually?
Per the General Use Info on the Catt Plex product label: This product moves through the plant from the point of foliage contact to and into the root system. Visible effects on most annual weeds occur within 2 to 4 days but on most perennial brush species may not occur for 7 days or more. Extremely cool or cloudy weather following treatment may slow the activity of this product and delay visual effects of control. Visible effects are a gradual wilting and yellowing of the plant that advances to complete browning of aboveground growth and deterioration of underground plant parts. This product will not prevent new growth in the soil or water so you would need to reapply as new plants come up, however it will completely kill a plant you spray it directly on.
