Americans pronounce hedges as HEH-juhz (/ˈhɛdʒəz/). Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "He mowed the lawn and trimmed the hedges over the weekend".
Record yourself saying "hedges" and play it back. The mic stays on your device — nothing's uploaded.

The textbook way isn't wrong — it's just not how anyone actually says it.
Stress falls on the first syllable, not the others. Stretch HEH — keep everything else short and quick.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
