Hoya Plants Growing Basics
Have you successfully grown cactus or succulents’ plants? If yes, then you 75% ready for hoya plants. The main different between growing hoya plants verses succulents are the amount of light and temperatures. Many cactus varieties will survive freeing weather and extreme temperature changes. In the desert, most cactus and succulents love bright long hours of sunlight. These two things sun and temperatures are the main differences between hoya plants and succulents/cactus.
When growing hoya plants, keep the growing environment warm above 50 degrees. The sweet spot for most hoya plants is between 70 and 85 degrees. Several hoyas will handle temperatures down to 40 degrees during winter. However, no hoyas I know of will handle freezing temperatures what-so-ever.
Epic Grower recommends making 50 degrees as the determination point. Just because a plant can handle colder weather does not mean they will not suffer. Now on to light.
Many people confuse direct sunlight with indirect sunlight. A bright window is NOT direct sunlight. Keep it simple. If the plant can SEE the sun unfiltered (not through tinted glass) then its direct sunlight. The exception is shade cloth. True plant shade cloth is designed to allow sunlight through while inhibiting some UV light. IF growing hoyas under a shade cloth use 50% to 70% shade rating.
Hoyas vary in their light requirements to flower. However, 97% of them prefer shaded indirect light. They grow great in covered patio areas with strong indirect light. If you have a covered front porch, they make great hanging or draping plant specimens.
They will handle a couple hours of morning direct sunlight. But they do not like afternoon direct sunlight. They are great indoors in or close to a bright window, Yes, a few hours of direct through window sunlight light is OK.
Watering hoya plants is easy. In nature most prefer humid warm and wet climates. However, in nature they do not grow in soil. Just like a cactus/succulent, when you grow hoya plants you need to let the soil be on the dry side. Water them once a week and then let the soil dry out for a few days. Yes – you can mist the plant when they start to develop areal roots. Use cactus soil that drains very fast. Make sure you pots have holes in them so they do not retain any water.
