Hoya kerrii is a climbing plant that can grow up to 4 meters high (around 13 feet). Stems have a diameter of 7 mm. The leaves are 6 cm wide, 5 mm thick. Adult plants show inflorescences of 5 cm diameter and up to 25 flowers. They produce small balls of nectar, coloured red to brown. They smell only faintly or not at all.
Treat your Hoya Kerrii like a succulent. Water it once a month or every 15-day since they tend to rot quickly. Always remember under watering is better than over-watering. If you cannot understand how much water your plant needs, water it tills your finger picks up dirt once you press against the soil.
Being a tropical vine, Hoya Kerrii loves the sun. So make sure to give it sunlight for at least 5-6hrs a day. Place it by a south-west facing or a west window so that your plant gets abundant sunlight. Avoid dark spots or direct sunlight as it may sometimes burn the leaves. During winter, you can place your vine under Grow Light. Hoya thrives well in natural, indirect, bright light.
After a whole year since the first repotting with fresh soil, I started fertilizing my kerrii with diluted Marphyl soil enhancer. I also spray the leaves with AgricultureRx GardenRx Spray. Since it’s a very slow growing plant, I really don’t know if the fertilizer helps — but no damage done!
Your precious vine needs well-draining soil so mix your own. Get pre-mixed potting soil (50%) and add perlite (25%) along with orchid bark (25%). You can throw in some sand as well. If your mix is not well, the soil will retain too much water, and there is a high chance that your roots will rot.
With watering and outer pots, be careful to check that your plant is fully drained before returning it to its pot. Drainage is really important!
