Hoya Krohniana will like to be grown in airy, well-draining soil. You may create a perfect mix by combining peat or coco coir, perlite, and orchid bark.
Hoya Krohniana Fertilizer
As Hoya Krohniana is a light feeder, it does not require a ton of fertilizer. However, feeding from a liquid fertilizer high in phosphorus indicated for houseplants will help your Hoya bloom. Feed your plant once monthly from spring to summer, ensuring that you follow all label instructions. Do not feed in winter during dormancy.
Hoya Krohniana Watering
Like many other Hoya’s, Hoya Krohniana will like to remain consistently moist but not oversaturated with water. You should water your Hoya after the top 1-2″ of soil has dried. Depending on growing conditions, you will likely need to water your plant up to twice a week during the warm summer months. Watering frequency may be reduced in winter.

Therefore, you may aid your plant’s growth by misting the plant frequently and using a humidifier or pebble tray.

Select a container that is 2″ larger than the previous one, and repot your plant being careful to disturb the roots as little as possible. Water your Hoya thoroughly and place it in indirect light. Although your plant may droop slightly after repotting, it should perk back up within a few days.
