A bark-rich Hoya substrate designed to create a very open, structured and fast-draining root environment.

Forty-five percent graded pine bark forms a durable framework, while chunky perlite increases aeration and coco husk chips retain moisture without introducing fine coco pith.

• 45% graded pine bark: Combines 8-15 mm and 15-25 mm particles for varied coarse structure.
• 25% chunky perlite: Low-dust 5-15 mm particles preserve lightweight air spaces throughout the mix.
• 10% washed and buffered coco husk chips: Adds structured moisture retention through 10-15 mm particles.
• Limited fine organic fraction: Keeps the root zone more open than a conventional soil-heavy houseplant mix.
• Laboratory-informed development: A tested sample measured approximately pH 5.9.
• Published recipe: Measured, mixed, inspected and packed by PlantScraper in Prague.

• Hoyas with epiphytic or semi-epiphytic growth habits
• Dischidias and similar plants suited to coarse substrates
• Plants requiring an open root zone and efficient drainage
• Ventilated pots and hanging containers with effective drainage
• Growers replacing dense general-purpose potting soil

Use directly from the bag in a pot with effective drainage.

Position the root system and work the mix gently around it. Tap the pot to settle the particles without compressing the bark into a dense mass.

Water thoroughly, then allow excess water to leave the pot. The chunky surface may dry before the centre, so check moisture around the root zone rather than watering only by appearance.

The mix contains no added fertiliser. Feed according to the Hoya's active growth, light and seasonal conditions.
