Wear long, protective clothing. While wild serviceberries do not have thorns, branches can still scratch and thorny plants can grow alongside serviceberries. Look for serviceberry plants along the bottoms of boggy areas and along the sunny edges of woods and forests.
Wrap your hand around a bunch of ripe, purple serviceberries and pull gently, popping the berries off the bush and into a pail positioned beneath the berries. Small pieces of stem may remain attached to the berries.
Remove all stems from berries once you have returned home and wash the berries under running water. Fill a bowl with water and place the berries in the bowl, discarding any that float.
Set the berries on paper towels to dry. Berries can be eaten raw, or may be cooked in water to extract juice for jam, syrup, pies or other uses. Cooked seeds are harmless to eat -- raw seeds contain minuscule amounts of cyanide and should not be eaten in quantity.
