Hibiscus plants are among the popular flowering plants that gardeners grow at home. They are famous for their large and beautiful flowers. Additionally, hibiscus plants are easy to grow and care.

Giving your hibiscus plants less than 6 hours of sunlight every day will lead to a low growth rate and poor blooming. Even so, this plant can tolerate shady environments but remember about its growth rate.

Hibiscus flowering requires ideal temperatures ranging from 60 to 85 degrees Fahrenheit. Tropical hibiscus plants require this temperature range throughout the year. Exposing your plants to temperatures below 60 or above 85 degrees Fahrenheit can damage or kill your hibiscus plants.

The amount of water your hibiscus plant will require depends on the amount of light and temperature you expose it to. If you’re growing the plants in high-temperature regions and you should expose them to direct sunlight for long hours, frequent watering is vital. Summertime necessitates daily watering.

Adjust your watering accordingly as it gets colder. Hibiscus plants don’t require frequent watering during winter. Check whether your plants require watering by dipping about 1-inch of your finger in the soil to check for moisture. Only water your hibiscus plants if the soil feels dry to touch. Avoid overwatering your hibiscus during winter to circumvent root rot.
