If thy were all cut down last year, then you have autumn fruiting primocanes. If you tip them, they will probably produce a crop early next year, and new canes produce a later crop. My Terri louise do this. Polka , I cut completely to the ground in the winter, and they start fruiting before the autumn crop Terri Louise.
Summer fruiters, like Glen ample, will only have produced a cane this year to fruit next year if they were cut to the ground last year. Hope that helps.
