How to Water Pop Star^®

Pop Star^® loves water but does not love when it’s overwatered. Here are tips on how to water Pop Star^® to make sure it’s healthy and hydrated all season:

• Check the soil before watering and only water if the soil is dry.
• Water the ground underneath the entire width of the stems, which is called the dripline, and not just at the base. Avoid watering over the top of the blooms and leaves.
• Water in the morning to allow the water to soak into the soil and roots before the warmest part of the day
• Give your plant a good even soak. It’s better to water deeply and less frequently than watering a little bit every day.
