3. Optimal Seasonal Timing & Temperature Thresholds
Spray in early fall or during full bloom in mid-summer when roots are actively storing nutrients.
Do not pull stems by hand, as root fragments regenerate new shoots.

- Arrowhead-shaped alternate leaves with blunt lobes at the base
- Twining, vine-like climbing stems that wrap tightly around grass blades
- Funnel-shaped white to pink morning-glory-like flowers on long stalks
