I bought 2 raspberry bushes and 1 blackberry bush. And planted them this spring (Monrovia grown). Should I prune them? When after a frost? How much should I prune them? Should I go back to about 1/3? The blackberry flowered slightly, and the raspberry very very slightly. I can't remember which stalks flowered.
Also what to prune if anything and when for honeysuckle and trumpet vines (Monrovia grown) .
thanks.

You can prune the blackberry canes that have produced fruit down to the ground immediately after harvest. In the very early spring select the thickest remaining canes and cut them back to about 7'. Remove the spindly canes completely, and prune back the side branches to direct growth into new, flowering stems near the tops of the remaining canes. Following this pattern should provide healthy, productive canes year after year.

Raspberry pruning depends upon whether yours produce a single crop or are everbearing. Prune in spring when starting to leaf out. Remove all weak canes and leave the strongest and most vigorous. Ideally canes that are ?" diameter at 18" above ground level. Cut back tips of all remaining canes. Remove any old fruiting canes left and dispose of them. Do second pruning immediately after harvest. Remove old or dying fruiting canes and dispose of them. Fall bearing varieties can be pruned by cutting back all canes to ground in spring. This results in only a fall crop with good yield.

Your honeysuckle and trumpet vines won't need to be pruned until spring, when new growth begins.

Best wishes with your landscape!
