How to check if trees are healthy ?
| Area | Healthy Signs (✅ Good) | Unhealthy Signs (❌ Warning) | Possible Reason |
|---|---|---|---|
| Roots | White, firm roots; deep penetration; no foul smell | Black/brown, rotten roots; hollow/chewed roots; foul smell; shallow roots | Root rot (fungus), termites, poor drainage |
| Stem / Trunk | Smooth bark, straight growth, no cracks or holes | Holes with frass (borers), bark peeling, canker lesions, cracks | Stem borers, fungal canker, mechanical injury |
| Leaves | Green, shiny, uniform growth, no distortion | Yellowing, drying from base, spots, curling, powdery coating | Nutrient deficiency, fungal rust/leaf spot, sucking pests |
| Canopy Growth | Dense, balanced branches, regular new flush | Sparse canopy, premature leaf drop, uneven growth | Stress from drought, pests, nutrient imbalance |
| Water Signs | Moist but well-drained soil; no standing water | Standing water at base (waterlogging) OR cracks from drought | Waterlogging → root rot; drought stress |
| Soil Fertility | Dark, crumbly soil; earthworms present | Hard, compacted soil; no organic matter | Low fertility, soil compaction |
| Nutrients | Uniform green growth, steady height gain | Stunted growth, interveinal chlorosis (yellow veins), small leaves | N, Zn, Fe, or Mg deficiency |
| Pests | No chewing marks, no webs, no abnormal swelling | Chewed leaves, rolled leaves, swellings (galls), visible insects | Caterpillars, gall wasp, leaf rollers |
| Diseases | No lesions, smooth bark, healthy flush | Leaf rust (orange spots), powdery mildew (white coating), black canker | Fungal/bacterial attack |
| Climate Effects | Steady seasonal growth, tolerates rain | Frost burn, sun scorch, hot wind drying, storm breakage | Frost injury, heat waves, storms |
| Management Signs | Correct spacing, good airflow, pruned regularly | Overcrowded, tangled branches, no pruning | Poor plantation management, disease spread risk |
🌿 How Farmers Can Use This:
- Check plants weekly for symptoms in each area (roots, stem, leaves, water, soil).
- Mark unhealthy trees early (tie a ribbon/flag) for treatment.
- Take 2–3 sample plants to dig roots or inspect closely.
- Record observations (how many affected) to track spread.
