Tulip Tree Yellowing with Black Spots: Soil and Tissue Testing Needed

20-year-old tulip tree never blooms. Late June: leaves yellow, black spots, fall off. Fertilizing helped marginally. Watering no effect. No parasites seen. Soil deficiency?

Action: Test Soil AND Leaves

Send soil sample + leaf tissue sample to Extension lab. Identifies nutrient deficiencies/toxicities, pH issues.

Possible Fungal Leaf Spot

Black spots could be fungal, but test first to rule out nutrition.
