Wash and trim okra. Fill pint jars firmly with whole okra, leaving 1/2-inch headspace.
Place 1 garlic clove in each jar.
Combine salt, hot peppers, dill seed, water, and vinegar in a large saucepan and bring to a boil.
Pour hot pickling solution over okra, leaving 1/2-inch headspace. Remove air bubbles, adjust headspace, wipe rims, and apply lids.
Process pints in a boiling-water canner for 10 minutes at 0–1,000 ft, 15 minutes at 1,001–6,000 ft, or 20 minutes above 6,000 ft.
