Hoya Potting Mix

• Coco coir and coconut husk chips: retain a controlled amount of moisture while keeping the mix light.
• Orchid bark: creates chunky structure and extra airflow around epiphytic roots.
• Perlite: improves drainage and reduces compaction in the pot.
• Activated carbon: brings a small porous carbon fraction; it does not replace fast dry-down, suitable pot size or removal of decaying material.
• Worm castings: provide natural, slow-release nutrients.
• Lava gravel: gives weight, structure and additional aeration.

The balance of chunky and fine components is tuned so the substrate stays open and free-draining while still holding a thin film of moisture on particle surfaces.

• When to repot: repot when roots fill the pot, when the old substrate has collapsed, or when watering becomes difficult to control.
• Prepare the plant: remove Hoya from its pot and loosen old mix gently, keeping functional roots intact.
• Root check: trim dead or rotten roots with clean scissors. Rinse only if compacted old soil cannot be removed safely by hand.
• Pot choice: choose a pot with drainage holes and avoid oversizing, because Hoya roots often dislike staying wet too long.
• Planting: add enough Hoya Potting Mix to set the plant at the right height, then backfill lightly around the roots.
• First watering: water lightly after repotting if roots are firm; wait longer if roots were trimmed or damaged.
• Ongoing watering: let the mix dry well between waterings, adjusting for leaf thickness, pot size, light and temperature.

This is a prepared Hoya mix. Choose Hoya Substrate Set for the lean bark-led ingredients separately.

• Moisture behaviour: fast-draining with moderate moisture retention; dries more quickly than standard potting soil.
• Structure: high proportion of bark, husk chips and mineral components for an epiphyte-friendly, open texture.
• Organic content: coco-based with worm castings for long-term, gentle feeding.
• Structural stability: normally 3–4 years indoors before bark and husk start to break down enough that drainage slows.
• Use-cases: best for Hoyas and other epiphyte-like houseplants that prefer a loose, airy substrate and partial dry-down.
• Safety: Potting substrates are for plant cultivation; do not allow children or pets to ingest substrate ingredients.
