Why Pine Needles Belong on Top, Not In, Carnivorous Plant Soil Mixes

Pine needles are excellent winter mulch (insulation, slow freeze-thaw). In soil mixes, they decompose in constant moisture, releasing nitrogen and resins that damage sensitive roots.

Use only recommended soil mixes for your species. See our care sheets for formulas.

Good growing!
