Periwinkle flower plant (Sadabahar) is quite drought-tolerant and actually prefers slightly dry conditions. Overwatering is one of the most common issues with this plant, especially in summer when people assume more heat means more water is needed.

Here are a few quick tips to keep Periwinkle healthy in the summer:

• Check soil moisture: Stick your finger about an inch into the soil—if it feels dry, it’s time to water.

• Use well-draining soil: A mix with sand or perlite helps prevent waterlogging.

• Water early in the day: This gives the plant time to absorb moisture before the sun evaporates it.

• Avoid wetting the foliage: Water at the base to reduce the risk of fungal diseases.
