Things You'll Need
Instructions
Choose the area where you plan to pick wild berries. If you are planning a hiking trip, find out which area you will be hiking through.
List the wild berries you are likely to find in that area. Buy a local field guide on the area's plants and study the characteristics of both edible and toxic wild berries. Experience in the field is the best teacher for these type of skills. So if you are new to an area, go with an experienced berry-picker until you are familiar with the local plants.
Look for wild varieties of berries you are familiar with. This will reduce your chances of picking a poisonous variety. The wild varieties look just like the ones we buy in the supermarket only smaller.
Pick seedy-aggregate berries, those that are made of little clusters like raspberries, as no aggregate berry is known to be poisonous. In North America, there are many species of aggregate berries, such as blackberries, raspberries and bay berries, all of which are edible.
