This premium soil mix has everything your hoya plants need. This soil mix is peat free, and contains perlite, worm castings to improve growth and aid drainage. Comes in a re-sealable bag. 

The added activated carbon helps prevent root-rot-related issues. There is orchid bark and coco husk to support space and aeration. This mix drains relatively quickly as Hoyas prefer to be left to dry between watering.
