Raspberries are ripe when the fruit is fully colored. Also, ripe berries slip easily from the receptacles, which remain on the plant. Raspberries are very perishable. They should be harvested every two or three days, handled carefully, and refrigerated or frozen immediately. Raspberries can be stored for only three to five days in the refrigerator.
Strawberries are fully ripe when uniformly red.
Pick the berries with the cap and stem attached to retain firmness and quality. Don't pull them off. Strawberries can be stored in the refrigerator at 32 to 40 F. Use within 2 to 5 days. Strawberries should be picked about every other day in warm weather, every 3 to 4 days in cool weather. The harvest period for some June-bearing varieties may last three to four weeks.
