Hoya kastbergii aka Hoya Kastbergii

Hoya Kastbergii’s native range is Southeast Asia and Australia.

Hoya Kastbergii does best in dry soil and should only be watered sparingly.

Hoya Kastbergii loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

To ensure optimal growth, the Hoya Kastbergii prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

No extra humidity is necessary for the Hoya Kastbergii. Absorption of water by plants is primarily done through their roots, and soil watering is the most effective method to provide humidity to your plants.

Repotting the Hoya Kastbergii should be done either when it has doubled in size or on a yearly basis, whichever occurs sooner. Fresh potting soil with all the required nutrients, refreshed annually, will provide the plant with all the necessary sustenance, making the use of fertilizer unnecessary. Keep in mind that plants receive their energy from the sun, not fertilizer.

There is no verified data on the toxicity of this plant in the records of Ploi. If any person, including yourself, a family member, or a pet, consume plant material with an uncertain toxicity level, it is advisable to seek the advice of a healthcare expert.

A standard dormancy pattern is absent in the Hoya Kastbergii. If the growth slows down noticeably, make sure that adequate sunlight and water are provided to support the plant's growth.
