I have ‘Heritage’ raspberries. I cut all canes back to the ground on that first March day when the sun is shining and I NEED TO DO SOMETHING IN THE GARDEN.
My reason being: Yes, Heritage bloom on old and new canes, but I want just ONE crop, late in the season (I have raspberries to pick right now) because by then the Japanese Beetles and the ‘Picnic Bugs’ (also a small beetle) are dead and gone and won’t bother my fruit.
As R.S. is a dwarf cane, I would probably leave all canes for now but when they all start to leaf out next spring, cull out any dead or damaged canes.
I read up on it - sounds pretty carefree, actually.
Thanks! I have only one; Its in a gardening bag inside a 10 gallon black trade pot so I can move it around. I never saw any June bugs on it. They seem to prefer my 2 plum trees more than anything else! (If they bloom in the spring I have bags to cover them and keep the Japanese beetles out.)
I did have problem with grasshoppers. They probably ate about 25% of the berries. They seem to like rhubarb leaves peppers and tomatoes too.
