vinca plants about 1 1/2 in. tall
The stems have turned yellow and spindly but still blooming. Southern CA - mainly sun especially in afternoon. This has happened in Feb/March. Maybe too much water or bugs? One plant in a different area with not much water is nice and green and bushy. What is wrong?

Yellowing stems is a sign of watering issues. Make sure the soil is well draining and that they are not sitting in soggy soil.
