Q

My raspberry bushes are gigantic and are not producing berries. How do I prune them to avoid this? Can they be pruned right now or do I wait for Fall?

Answer(s)

A

I don't know what variety of raspberries you have, but generally, you'll need to do some thinning and pruning back for better fruit production.  The pruning timing depends on if it is a June-bearing or ever bearing raspberry.

Fertilizer addition has to be timed properly, otherwise the plant will push energy into vegetative (leaf) growth and less into fruit production.  The excess growth you refer to I believe is due to over fertilization.  Because these raspberries have been in for awhile, the soil conditions may not be ideal for good fruit production.  High organic matter, good drainage, and weed free.  Sometimes raised beds are preferred to have the good drainage and high organic matter suitable for raspberries.

Here is a link to a fact sheet on  Red Raspberry production that may help you with produce better berries.
