Summary
Eighteen agricultural planning tools backed by 5,000+ crop calendar entries, 1,004 companion relationships, and 506 pest associations. You get frost-anchored planting windows by USDA zone, succession schedules, crop rotation families, and growing degree day models for harvest prediction. The pest intelligence layer is especially thorough: symptom diagnostics, OMRI-listed organic controls, and 200 beneficial insects with prey cross-references. All data runs offline via stdio transport. Reach for this when you're building garden planning features, agronomic advice systems, or need Claude to answer "what should I plant in zone 8b this month" or "which beneficials target tomato hornworm" without hallucinating dates or compatibility charts.

Data
| Asset | Count | Notes |
|---|---|---|
| Crop calendar | 5,006 entries | 14 categories (vegetable, herb, fruit, flower, cover-crop, root, legume, grain, mushroom, native, medicinal, fiber, forage, sprout). Frost-anchored windows; 120 entries carry climate modifiers across 6 climate types |
| Companion relationships | 1,004 | 510 beneficial, 95 antagonist, 12 mechanism categories |
| Growing degree days | 120 models | Cultivar-specific GDD ranges, base temperatures, NOAA Climate Normals harvest prediction |
| Rotation families | 12 | Nightshades, brassicas, cucurbits, alliums, legumes, umbellifers, grasses, amaranthaceae, composites, mints, malvaceae, miscellaneous. Every calendar slug mapped. |
| Succession chains | 33 | Greens, roots, legumes, brassicas, cucurbits, herbs, flowers, cover crops. Frost-anchored phases with per-climate notes. |
| Pest/disease associations | 506 | Crop-to-pest edges with diagnostic symptoms, organic management, prevention, and regions. OMRI-listed management only. |
