Soil Ninja Base Mix – Customisable Indoor Plant Compost

Soil Ninja Base Mix – Versatile Compost for Indoor Plants

Give your houseplants a strong foundation with the Soil Ninja Base Mix – a nutrient-packed, aerated indoor plant compost designed for most houseplants. It’s perfect for standard plant care and also highly adaptable if you’re tailoring media for specific plant types.

This blend includes generous aerators and a full palette of nutrients, creating plenty of air-spaces that encourage healthy root growth and help prevent problems like compaction and root rot.

What’s in the base mix?

• Coconut coir: retains moisture while staying lightweight.
• Perlite: improves drainage and soil structure.
• Worm castings: natural, slow-release nourishment and beneficial microbes.

How to customise your mix

For plants with specialist needs, you can adapt this mix easily:

• Sand (10-20%): speeds up drying, improves drainage — ideal for fine-rooted plants or when over-watering risk is high.
• Bark (20-50%): creates a chunkier texture and structural strength — great for taller or climbing species.
• Vermiculite (10-20%): increases moisture retention and aeration — ideal for plants that dislike drying out.
• Zeolite (~10%): acts as a nutrient reservoir and filters salts/impurities — useful for longer-term potting and maintenance.
