Q.leaves on cardinal vine turning yellow and brown
The leaves on my cardinal climber vine are turning yellow and brown. Vine is planted in a planter.
Yellow leaves generally are an indication of a watering issue.
To much or to little can cause yellowing leaves and if the plant sits in soggy soil or the roots dry out, eventually the leaves will die and turn brown.
Check the pot soil. Does it feel wet? The soil should be moist but never soggy. The soil should be well draining and the pot have an adequate drainage hole.
If the soil is dry, water. With warmer summer temperatures you will need to water twice a day if it is 85 degrees or more.
Cardinal Climber Vine is generally pest free but can be bothered by White Fly. If you see any little bugs, treat with Neem Oil.
