Raspberries are promiscuous.
They are self-fertile and reproduce prolifically if left to their own devices they will spread very quickly. Pruning is simple and necessary to maintain order. Autumn-bearing raspberries or primocanes are the simplest to prune. All canes should be cut down to ground level in late fall after fruiting or very early spring before growth begins as the plants fruit on the new growth.
When pruning floricanes, you only need to remove the spent second year canes. They can be trimmed in the fall after harvest or in early spring when the dead and damaged canes are easy to identify among the new season’s growth. Never cut the new canes. Plantings can also be thinned out at this time if needed. Everbearing raspberries produce fruit on the top onethird of the plant, trim this off after fruiting, leaving the bottom two-thirds of the plant.
If you don’t want to share with your local wildlife you may want to cover your plants with netting. Otherwise plant a few extra and make the birds and critters happy. Raspberries are ready to harvest when they easily come off the plant when gently pulled. Pick and enjoy!
