Zinnias Thrive on One Side of Walk, Fail on Other: Microclimate Detective Work

Large zinnias grow beautifully on one side of 4-ft walk; same conditions, same soil, but poor on other side.

Investigation Checklist

Sun: After leaf-out, does other side get 6+ hrs direct including noon? Zinnias need heat.
Drainage: Is one side wetter? More organic matter? Nearby tree/shrub roots?
pH: Test both sides. Cement leaching, lime applications affect pH.
Soil compaction: Traffic, bed age, tilling depth differences.
Gravel/rocks/irrigation: Hidden barriers or uneven watering.

Something differs. Keep asking "what's different?" until you find it.
