Frequently Asked Questions
What’s the difference between vermiculite and perlite?
Vermiculite retains water and nutrients well, making it ideal for moisture-loving plants. Perlite provides excellent drainage and aeration, better suited for plants that prefer drier conditions.
What ratio should I use for seed starting?
A 1:1 ratio works well for most seed starting mixes. For plants prone to damping off, consider increasing perlite to 2:1 (perlite:vermiculite) for better drainage.
Can I use this mix for container gardening?
Absolutely! A vermiculite/perlite mix improves soil structure in containers. Adjust the ratio based on your plants’ water needs – more vermiculite for moisture retention, more perlite for drainage.
