So every time I open up my pruning book to the raspberry page, I get deep unhappy furrows in my brow. Raspberries are a simple plant. Why do they have to make it so complicated?
There’s the summer-fruiting kind (with a short fruiting season), which fruit best on one year old wood. Ideally with these, you should prune out the canes that have fruited right after they finish (late summer/early fall) and leave the current year’s canes (the brand new fleshy green ones) to fruit the following year.
Then there are autumn-fruiting raspberries (with a longer fruiting season) , which fruit on the current season’s growth. You aren’t supposed to prune out the fruited canes right away like with the summer-fruiting ones. Instead you cut every cane down in late winter when the plants are fully dormant, and allow all new canes to come up in spring.
The problem is, most people have no clue which type they have.
So I was pleased to read recently that there’s a simple rule that works for both varieties: In winter, just remove any canes that gave you fruit, and you are good to go. The stems that once held fruit will still be clinging to the canes, making it easy to tell.
If the vast majority of canes fruited last year, it’s likely you have an autumn-bearing variety. Don’t be alarmed if you basically cut the lot of it to the ground.
If only some of them fruited last year and the rest of the canes seem green and fresh, it’s likely you have a summer-bearer. Either way? The simpler rule of pruning works fine.
Hope that helps you feel confident to get out there and prune your raspberries!
(By the way, the same rule is good for Boysenberries, Blackberries, and Loganberries, which all fruit on one-year old canes – just prune out the canes that fruited for you, and tie the fresh new ones to your trellis! Simple, right?)

Pruning can be so intimidating, but you do a great job simplifying the information for the different plants. I enjoy all your pruning posts and videos.
The photo is great–makes me want to plant some raspberry canes right now, or maybe just go to the market and get some raspberries…

Hi Genevieve, that really is a help. I am new to the raspberry growing world and have not done any pruning yet. There are few canes anyway but I think they did bear, so down they will go. Next season I will try and pay better attention to when they flower and fruit. You have done a great service to us, thanks.

I got several raspberry plants from my dad in zone 5 and I live in zone 4. I planted them and have never done anything in 2 years. I didn’t know you had to prune. Some of the canes are 5-6 feet high, they didn’t bear fruit. The small one’s did bear fruit. They got about 3 feet high. They bear fruit in July. Do I prune in the spring? Or just leave it til fall?
So it is end of May (5/23) and i did not get around to pruning last fall, this past winter or this spring. I planted (about 4 feet apart) a white and a red raspberry plant and they bore well last year (when i could see through the canes and collect the berries. now they are just one giant mass of green–about 6 feet tall and footprint about 4 feet x 7 feet. I obviously need some radical surgery, but is it too late to cut them to the ground? Can’t imagine how to tell which ones gave fruit last year. Help please
Yeah, it’s too late. Leave em’ be – you’ll get berries, just not the super-best yield possible. Cheers, Gen
I’m new to raspberries but seem to have very happy second year plants with lots of fruit.
I also have a center stalk coming up from each of the main plants that seems to be getting taller by the day and bigger in diameter. No fruit and no big canes either but a foot or two taller. Just curious to know if I should cut them off or leave them?
The rest of the plants look great and are heavy with fruit.
Looking forward to your response.

Leave ‘em be. I bet those are going to be some good fruiters next year.
Please help me, I can not understand this.
I have just moved to a home with rows of raspberrys. There are canes with fruit with thorns, and many tall canes without fruit and without thorns,[ Green smooth shoots ]. Should I be pruning out those without thorns? It’s July 1st and I’m in the pacific N.W.
Thank You,
Marilyn
You don’t prune at all until winter, Marilyn. Then you prune out anything that fruited. So leave it be until the end of the year. Hope that helps!
I tie some colorful yarn around the canes that produce fruit, so when I have help pruning, they cut off the right canes. Also I have been looking for white raspberry bushes, and have found nothing. any suppliers would be a great help
