Light Needs

Partial shade works great for it since direct, scorching sunlight may cause sunburn. However, it is used to full sun in tropical areas, so 6 to 8 hours of direct sunlight does no harm, if it is acclimatized.

How Often To Water Hoya Obscura

It prefers regular watering with adequate intervals to let the soil dry and keep it safe from overwatering. Like all succulents, it develops fungal infections and rots when left in standing water. Reduce the water input even more during the winters, and always check if the soil is dry with your fingers before watering.

Fertilizer

During its growth period, fertilizing in the summer and spring greatly enhances the development process. It would be enough to use a balanced fertilizer at half its recommended strength twice a month in the warmer months.

Soil

Although it is not fussy when it comes to the type of soil, a well-draining, porous mix serves the best. You can enhance the drainage by adding perlite, charcoal, and other gritty material to a regular potting mix.

When to Repot Hoya Obscura

Unlike other succulents requiring regular repotting, Hoya Obscura rarely requires a repot. In fact, repotting it may induce adverse stress on the plant. Check it early in Spring and repot it only if crowded.

Humidity

Due to their origin in tropical areas, they grow best in high humidity levels. Ideally, the humidity level should be 60% for it to mature. The household air also works fine as long as you spray the plant twice a week or so.

Temperature

Aim for 20-30°C (68-86°F) in the day, and 10°C (50°F) at night.

How to Propagate Hoya Obscura

Hoya Obscura propagates best through stem cuttings. Take a few cuttings during early spring or summer and plant them in well-draining soil. Make sure the soil is moist and not wet. Allow it to grow for 3-4 weeks to see the stems produce roots.
