Troubleshooting Common Problems
 
Yellowing Leaves: Often caused by overwatering or nutrient depletion. Let soil dry between waterings and adjust fertilizing frequency.
 
Root Rot: Caused by compacted or waterlogged soil. Always ensure free drainage.

Botanical Context and Etymology
The genus Hoya was named in honor of British botanist Thomas Hoy (c. 1750–1822). Hoya kaikoeana was formally published by Wanntorp et al. in 2014 and is considered distinct based on floral morphology and habitat. The collector’s trade name “sp. Dahlia” is still used in cultivation, though kaikoeana is the accepted species name.
