Locate an area where blueberries grow wild. This must be public land; do not pick blueberries on private property. Check with local authorities in Trumbull to make sure that picking blueberries in the state park is legal.
Choose several baskets or other containers in which to place your blueberries. Trumbull's monthly flea market downtown is a wonderful place to purchase these. Line your containers with wax paper or paper towels to absorb the juices of the blueberries.
Drive to the Trumbull, Connecticut, location you've chosen. If you have blueberry bushes growing in your own yard, then it will be a short trip. If you are driving to Trumbull's Pequonnock River Valley State Park, be sure to pull your car completely off the roadway and park in a safe location.
Search on high and low blueberry bushes in wooded areas. Most rural areas of Trumbull, Connecticut, contain small and large pockets where blueberries grow profusely.
Pick the blueberries. Wear gloves when picking any type of berry to keep from staining your hands. A thin garden glove works best.
Place the berries in a colander, and rinse them in cold water before eating them. Trumbull's sandy soil accumulates easily on berries growing outdoors. Let the blueberries drain on several paper towels before baking or cooking with them.
