Raspberries are ripe when the fruit are fully colored. Ripe berries easily come off the receptacle that remains on the plant. Raspberries are very perishable. They should be harvested every 2 or 3 days, handled carefully, and immediately refrigerated or frozen. Raspberries can be stored in the refrigerator for only 3 to 5 days.
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 40oF. 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.
