The season for them is generally a short one. Begins in early July and last for 2 to 3 weeks. Black raspberries tend to ripen before most red raspberries varieties expect for the early ripening summer ones.
Find out what type of raspberries you have (summer-bearing or ever-bearing) before pruning. See our pruning advice on this page. For best growing conditions it is recommended for rows to be 1Â½ to 2 feet wide and to have about 3 canes per linear foot. Wait until early spring to prune and to remove suckers. have raspberry plants that 4 or 5 yrs old. they grow beautifully and produce lots of fruit but the fruit are little and when picked fall apart in my hand while picking. They also have lots of tiny little seed type things that are hard to separate from fruit when I wash them.
