How to Care for Hoya Obovata
Hoya Obovata is a low-maintenance, succulent plant. It needs temperatures in the range of 60 and 85 degrees Fahrenheit. To pot Hoya, you need a potting mix that contains peat, perlite, and fine orchid bark. You need to keep your Hoya plant near the window from where bright indirect light will fall on your plant.
Hoya plants do not need too much watering. Over-watering will kill your hoyas. Water the plant only when you feel that the top surface of the soil pot is dry. Hoya Obovata needs 60 percent humidity and is drought tolerant.
Let us look at its basic requirement of soil, temperature, humidity, water, and light in detail. We have compiled an easy guide for you to follow.
– Soil Requirements
The Hoya Obovata plant needs moist soil to grow. It should not be water-logged, and the pot or container should have good drainage. The potting mix for Hoya Obovata should contain peat, perlite, and fine orchid bark. Such a combination offers good drainage, thus reducing the risk of root rot.
Add horticulture charcoal to the potting mix to improve the drainage of the soil. Charcoal is the best choice to add to the potting mix because it absorbs excessive water. Charcoal also absorbs impurities and protects the potting mix from bacteria and fungi.
Garden soil is not suitable for Hoya Obovata because it is compact and dense and does not allow the air, water, and nutrients to pass through. Thus the garden soil is harmful to the plant as it deprives the plant of essential nutrients. Adding perlite and pumice improves the aeration in the soil and encourages robust growth.
– Light Requirements
Hoya Obovata needs bright light for their growth. Provide a sufficient amount of light if the plant is indoor. Keep the plant near a window so that the plant can get proper lighting.
The ideal location is an East or South facing window. However, you should arrange a curtain to filter the direct exposure of light or keep your plant at a distance from direct sunlight exposure. Arrange a substitute or an alternative of natural light if the plant is indoor.
You can arrange LED grow lights as an alternative to the natural light of the sun. They are suitable for growing Hoya Obovata indoors as they emit the right intensity of light for the support of the plant.
– Water Requirements
The leaves of Hoya Obovata are very thick. They retain more water than those plants with thin leaves. Due to this quality, the plant can survive without getting water for a few weeks. Water your hoya only when the top two inches of soil are dry.
If you feel that the soil is moist, you can wait for a couple of days to water the plant. Control the water to minimize the risk of root rot, which is caused by overwatering the plant. In winter, you should avoid giving water to the plant for weeks. In cooler months, the water is retained in the leaves for a long time due to less evaporation.
Hoya Obovata needs less water because they are semi-dormant and slow growers. It is another reason they only need a limited amount of water. The trick to healthy hoya plants is to check the soil before watering.
– Temperature Requirements
The Hoya Obovata grows better in a warm climate. The temperature ranging between 60 and 85 degrees Fahrenheit is ideal for their optimal Hoya Obovata growth rate. The plant should be kept safe during droughts. During drought, place the plant away from windows and doors to save it from warm and dry winds.
– Humidity Requirements
