How old are your plants and did any or all of the varieties sucker earlier this year?

Hi....most of my plants are planted this year, Floricane ( Coho ) is in a 3 gallon pot that i got from Lowes, about a 1 inch sucker popping up now, my other Floricane ( Taylor ) has a little sucker coming up now about 1 1/2 high, it suckered about 1 sucker new early this spring, now my Anne Raspberry suckered this spring as well as my Heritage which has a small sucker just popping up now about 1/2 inch tall, so i'd expect suckering in spring but this late in summer ?....only 1 Raspberry is in a pot the rest are established in the ground....me no SWD as far as i know

These are new, recently transplanted canes; give them a year or two to behave normally. Applying composted manure in the late fall will help next year's growth cycle.
