Choosing the Right Peat Moss and Drainage Amendments for Carnivorous Plants

Selecting Quality Peat Moss and Soil Amendments

A grower purchased sphagnum peat moss from a local hardware store but found it coarse, woody, and different from the fine, powdery peat previously obtained from Sarracenia Northwest. They also struggle to find perlite without added fertilizer.

Expert Guidance

Jeff Dallas advises buying peat moss only in large bales (typically found outdoors at garden centers). Smaller bags often contain fertilizers or inconsistent ingredients. Small sticks in peat are normal; the brand "Lakeland" from Home Depot is currently used by Sarracenia Northwest.

Drainage Amendments

Carnivorous plant mixes require a component to improve aeration and drainage. The best options are:

• Perlite: Look for large bags of untreated perlite in the outdoor section of big-box stores (often near concrete products).
• Silica Sand: Sold as "Commercial Grade Sand" in the concrete aisle; buy a 100 lb sack.
• Pumice: Mostly available on the West Coast.

If these are impractical, many carnivorous plant nurseries sell pre-mixed soils, though shipping can be costly.

Key Takeaway

Use a 1:1 ratio of peat moss to perlite (or sand). Avoid any media with added fertilizers, which harm carnivorous plants.
