Why are the leaves on my potted vinca turning yellow?
A Vinca plant can die from overwatering as well. Excessively wet soil can cause fungal diseases such as blight or leaf spot. Infected plants will start to show yellow to dark brown spots on the leaves.
How often do you water vinca in pots?
Watering Vinca in Pots
Once established, typically the flowers will need water every other week. Follow the general rule that if the top 2 inches of soil feel dry to the touch, then water the plant. If the Vinca is receiving regular rainfall, then additional water is not needed.
What causes potted leaves to turn yellow?
Poor drainage or improper watering
Water issues — either too much or too little — are the leading reason behind yellow leaves. In overly wet soil, roots can’t breathe. They suffocate, shut down and stop delivering the water and nutrients plants need. Underwatering, or drought, has a similar effect.
