Raspberries (Rubus idaeus) are believed to be native to regions in Europe and Asia. They have been cultivated since ancient times for their sweet, tangy fruit and were brought to North America by European settlers. Today, raspberries are grown in many temperate regions around the world.
Prune raspberry plants in late winter or early spring. For summer-bearing varieties, prune out old canes that have finished fruiting and thin out weak or crowded canes to encourage new growth. For everbearing or fall-bearing varieties, prune all canes back to the ground after the fall harvest. Maintaining a tidy, well-pruned raspberry patch improves air circulation and reduces the risk of disease.
Harvest raspberries when they are fully ripe, usually indicated by their rich color and ease of detachment from the plant. Gently pull the berries off the cane, being careful not to squish them. The best time to harvest raspberries is in the morning when they are cool and firm. Store harvested raspberries in a cool, dry place and refrigerate them as soon as possible to maintain freshness.
General Prevention: To prevent pest and disease problems, ensure raspberry plants are well-spaced for good air circulation and sunlight exposure. Mulching can help retain soil moisture and suppress weeds. Regularly inspect plants for signs of pests or disease and treat any issues promptly. Avoid overhead watering to reduce the risk of fungal diseases, and keep the garden area clean and free of debris that may harbor pests. Rotate raspberry plantings every 5-10 years to prevent soil-borne diseases and pests from becoming established.
