About Soil in Crawford County, Pennsylvania
Acidic Northern Tier Soils
Crawford County soils have a pH of 5.08, falling slightly below the state average of 5.22. This acidic profile is much lower than the national median of 6.5, making it well-suited for woodland species.
Silty Soils over Bedrock
The composition is 47.9% silt, 25.0% sand, and 14.1% clay, though bedrock is the dominant structural feature. The high silt content gives the soil a smooth, floury feel when dry and aids in moisture retention.
Superior Moisture Storage
With an available water capacity of 0.169 in/in, this soil outperforms the state average for moisture retention. It also holds 10.74% organic matter, ensuring a steady supply of nutrients for local plant life.
Hydrology Shaped by Silt
While formal drainage classes are not listed, the high silt and organic content suggest the ground stays moist for long periods. Gardeners should plan for beds that take advantage of this consistent water availability.
Cold-Hardy Varieties in 6a
Hardiness zone 6a is perfect for growing potatoes, berries, and brassicas. Your soil’s exceptional water capacity means your garden will be more resilient against summer heatwaves.

Soil & Planting Advisory: Crawford County
Soil Verdict
Crawford County is in USDA hardiness zone 6a, a moderate climate zone. where winter lows can reach -10°F. Freeze-thaw cycles are moderate; soil biology slows in winter but recovers reliably in spring, supporting a broad range of plants.
Planting Guidance
A wide plant palette is possible: deciduous trees, most shrubs, cool-season vegetables, and many perennials thrive here. Winter protection (mulch, burlap wraps) helps push the zone boundary for desired species. Always match plant selections to the specific microclimate of your property — low spots, slopes, and wind exposure can shift effective hardiness by half a zone.
Soil Implications
Moderate freeze-thaw cycles naturally aerate the soil but can also cause compaction in clay-heavy areas; annual core aeration is beneficial. Organic matter amendments decompose at a moderate pace — aim for 3-5% organic content for optimal fertility. When soil temperatures drop below freezing, microbial nitrogen cycling stops; spring fertilization is more effective than late-fall application.
Regional Context
Crawford County closely matches the Pennsylvania average hardiness conditions.
