Syngonium Potting Mix

Sybotanica lists the following ingredients and relative proportions for its current Syngonium Mix. Measure each stated part with the same scoop; smaller additions have no published fixed ratio.

• Coco coir: 2 parts for a moisture-holding base
• Worm castings: 1 part, contributing mild organic nutrients
• Pumice: 1½ parts for mineral structure
• Perlite: 1 part, helping keep the root zone open
• Coconut husk chips: 1 part for chunky organic texture
• Small additions: Activated carbon, lava gravel and organic nutrients
• How to mix: Use one consistent scoop to measure the listed parts. Adjust chunk size to the root system and do not assume the finished blend is exactly 10 parts.

Use this mix when Syngonium need better aeration than generic potting soil can offer, but still react badly to long dry periods.

• Light: Syngonium prefer bright, indirect light; strong, direct sun can scorch leaves.
• Watering: keep the mix evenly, lightly moist – let the top layer dry slightly but avoid letting the pot dry out completely.
• Humidity: higher humidity is helpful; grouping plants or using a humidifier can reduce leaf crisping in very dry air.
• Temperature: warmth and stable conditions suit Syngonium best; avoid cold drafts and sudden temperature swings.
• When to repot: repot when roots become crowded, growth slows without another clear cause, or when the old mix has broken down and no longer drains well.
• Repotting steps: remove loose old soil carefully, trim dead or rotten roots if needed, add enough Syngonium Potting Mix to set the plant at the right height, then backfill while keeping the root crown just below the surface.
• Settling the mix: lightly press the substrate to stabilise the plant, then water thoroughly so the mix settles around the roots and air pockets close.

Monitor how quickly the mix dries in your specific light and temperature; adjust watering frequency rather than volume so the substrate can re-oxygenate between waterings.

• EC: approx. 1.0.
• pH: around 7.3.
• NPK (mg/L): roughly 58 – 6.8 – 145.
• Bioactive: Yes – compatible with many bioactive setups.
• Pet considerations: contains perlite, fertiliser and activated carbon and is not intended for ingestion by pets or children.
• Organic matter: about 60 %.
• Dry matter: about 40 %.
• Water retention: roughly 55 %, tuned for lightly moist but not saturated conditions.
• Structural stability: typically 3–4 years indoors before organic ingredients change enough to slow drainage.
