I'm curious -- were you instructed to prune the plants are just to to pinch blossoms the first year so that the plants don't set fruit? Who's giving the advice (i.e. is this a local or a mail order nursery)?

If you want a crop the first year, everbearing raspberries are the way to go. You can plant them in April, and have fruit to harvest in August. They will continue to bear fruit into October. Blueberries do best if the flowers and fruit are knocked off the shrub when they are transplanted.

shazaam- the advice was given by the owner/operator at a nursery that sells only blueberry plants. Advice was to prune. Alternative given advice was to buy container blueberry plants already contained to get berries for this year. Unfortunately this place is too far to drive and pick those up, and locally nothing like that available.

ericwi- Great advice on the raspberries. I always thought it was two years for them too. That won't help with our toddler. She won't eat them. "sour" she says. If I trasnplant the 3 year old plants and knock off flowers, can I leave any new flower growth on the plant after transplant..meaning get some fruit at least?

linzelu,
I'd leave some flowers. Brady

The reason to prune or not let the plant flower is to increase production in future years.

If you are more concerned about this years production then by all means leave half of the flowers on or leave flowers on half the plants.
You will get berries this year and next year-though maybe not as many next year.
