The frequency of watering will depend on several factors, including temperature, humidity, and the size of the pot. In general, during the active growing season (spring and summer), you may need to water your Hoyas every 7-10 days. However, always check the soil moisture before watering, as environmental conditions can vary.

During the dormant phase in winter, when Hoyas experience slower growth, waterings should be less frequent. As the plants require less moisture during this time, watering every 2-3 weeks may be sufficient. The key is to ensure that the soil dries out partially between waterings, preventing waterlogged conditions that can be detrimental to the plant’s health.

Signs of Proper Watering

Understanding when to water your Hoyas is crucial for their well-being. One way to gauge the water needs of your plants is to observe the leaves. When the Hoyas need watering, the leaves may start to pucker or wrinkle slightly. This is an indication that the plant is becoming thirsty and requires hydration.

Additionally, monitor the soil moisture by inserting your finger into the soil up to the first knuckle. If the soil feels dry at this depth, it’s time to water your Hoyas. However, if the soil still feels moist, it’s best to wait until it dries out partially before watering again.

Remember that these guidelines are general recommendations. Factors such as humidity, temperature, and the specific needs of your Hoyas may influence the watering frequency. It’s essential to observe and adapt your watering routine to provide the ideal conditions for your plants.
