Care Guide
Planting
Plant Scouler's Polypody in partial to deep shade - it thrives in the fog-drip conditions of coastal California and won't tolerate full sun. This fern prefers medium-drainage soil and actually does best when attached to trees, logs, or other organic matter rather than in standard garden soil, so consider planting it near the base of a tree or on a moss-covered log if possible. It spreads slowly by rhizomes, so give it room to expand over time. Plant in fall or winter to establish before summer.
After Planting
Water moderately during the first growing season, but once established, this fern needs minimal water - just once a month maximum during summer. The biggest mistake is overwatering; Scouler's Polypody is adapted to coastal conditions and doesn't need frequent irrigation like tropical ferns do. It's evergreen and low-maintenance, spreading slowly on its own without needing pruning. Expect it to tolerate cold down to 20°F, making it reliable for Bay Area winters.
