I guess it’s part of my personal philosophy. I work hard, but I don’t see the point of doing a job a certain way when there’s an easier alternative. So, I don’t dry dishes, because they’ll dry themselves in the dish drainer. And I take the easy way out when it comes to growing raspberries.
Raspberries, and other thorny bushes like blackberries, are brambles in the Rubus genus. They are perennials, but their branches (or canes) live for only two years. First year canes are known as primocanes, and second year are called floricanes.
Types of Raspberries
There are basically two types of raspberries you can grow – summer bearing, and fall bearing, also known as everbearing.
Summer bearing – these raspberries produce one crop of fruit in the summer on the floricane. Remember, that’s the second year cane.
Fall or Everbearing – these are the type of raspberries we grow, and they produce fruit on the tip of the primocane (first year cane) in the early fall, and then again during the next summer on the lower part of the same cane, so that 2 crops are possible per year. The easy way to grow them, which I’ll get to, is to manage them in a way that they produce only one crop per year, beginning in late summer and into the fall.
Pruning Raspberries
All raspberries need annual pruning, which generally requires being able to tell the difference between primacane and floricane branches. It’s really not all that difficult during the growing season. Primacanes are green and floricane are brown. But if you plan to prune during the winter, they are impossible to distinguish.
Summer bearing raspberries are pruned after they finish producing for the summer, and all floricanes are then removed.
How and when you prune will depend on whether you want one or two crops of everbearing raspberries. For two crops, pruning is done in the spring. Primacanes are trimmed, and floricanes are completely removed.
Keep in mind that everbearers actually produce the best crop by not allowing them to produce that early summer crop.
If you’ve ever worked around raspberry bushes, you know that they have thorns. They aren’t anywhere as wicked as blackberries, but still, they are enough to make you want to avoid getting in there to remove some canes, while leaving others.
The Easy Way to Grow Raspberries
Here’s where we get to the easy way to grow raspberries. We grow everbearing raspberries, and opt for a fall crop only. To accomplish this, all of the canes are cut down to 1″. No need to take the time to distinguish between primacane and floricane. Yes, we still have to face those thorns, but less time spent being picky means less thorns, right?
We generally prune in mid-winter, although pruning this way can be done anytime after the harvest is complete, but before new growth begins in the spring.
Growing fall bearing raspberries is generally best for zones 4 – 7. In areas with an early fall frost, there may not be enough time for fruit to mature. We have extended our fall season here in NE PA by several weeks, by covering our raspberry patch with a floating row cover.
Here is the raspberry bed in the middle of a snowless winter. The canes have been pruned and the bed mulched with wood chips.
How We Grow Raspberries
We grow Caroline raspberries, an everbearing variety, in our home garden (for zones 4 – 7). These are easy to grow, requiring little attention, and our 15′ x 4′ patch produces gallons of large, delicious berries.
We chose a spot in our yard that gets full sun and has good air circulation and good drainage. Raspberries hate wet feet. We began with just 5 plants, which we purchased from Nourse Farms. After just a few years these have spread to fill in the entire patch. As we mow the surrounding grass, any plants that try to spread are kept in check.
Our patch was prepared by creating a lasagna garden, a method of gardening that creates very fertile soil, rich in organic matter. The bed was prepared in the fall allowing the layers to decompose over the winter.
And then in the spring, the raspberry plants were planted about 2 feet apart down the center of the bed. We kept them well watered, especially that first year.
Each year we generally start getting raspberries near the end of August, depending on the weather. This past summer was particularly cool, and they didn’t start producing until mid-September or so. And they keep bearing right through to October.
As I mentioned above, we cover them with a floating row cover before the first frost to extend the season a few weeks.
After the canes are cut down to 1″, the patch is lightly covered with mulch; as this decomposes, it nourishes the soil. We use either hay or wood chips to mulch.
In the spring, we top dress with about an inch of compost. It’s best not to fertilize in the fall because this may cause new growth right before the plant goes dormant.
Because our conditions are perfect for raspberries, they are incredibly easy to grow organically. We’ve never had problems with disease, or even pests. And they attract lots of bees to our garden.
Staking Raspberries
We planted our raspberry bushes in 2012. While it’s highly recommended that all raspberry bushes be staked, regardless of the type you grow, ours have only recently been getting to the point where it’s becoming necessary.
Sooo, that means that at this point ours are not staked. That’s in the plan for the upcoming season, so I’ll update this post when we get that done. In the meantime, this post from Nourse Farms has information on staking raspberries.

I had a problem with Japanese Beatles that ate everything in site including the leaves on my raspberries I picked them off but there was to many of them
Susan Vinskofski says
We were able to get Japanese beetles under control by using beneficial nematodes to control the grubs in the lawn.
Anna says
I usually cut mine down in late fall to an inch too. I have never staked my raspberries and let them do what they do. I probably should but I haven’t seen an issue with them. However, I do try and keep them in a line and about 5 canes per plant. I started with 6 and now have 70 (or more but who is counting…) They do like to be watered and don’t mind a little afternoon shade. I am in zone 6.
Wasp love the berries so be careful when you pick.
Susan Vinskofski says
I do think that this way of pruning keeps them from getting too tall. We haven’t seen wasps, but lots and lots of bees, and ants, too.
Lisa Nyland says
I have a tried & true method for controlling Japanese beetles every year all season long. The key is to observe when you find the first group of beetles- in our CT garden around 1st week of July. These are the scouts. Gather all you can find and put them in a shallow plastic container filled with soapy dish liquid. Then (this is gross but it works) squish their guts out using any garden tool and leave the container out. Their scent will deter the swarm of beetles that follow the scouts and your yard will be free of pests all season!
Susan Vinskofski says
You’ll think I’m gross, but I’ve actually gotten to the point where I squish them with my bare hands and just leave them on the plant! We haven’t had as many beetles that past few years, so I guess it’s working!
rachel didlake says
I’ve had trouble with disease. My whole patch is infected with some sort of disease that produces black spots on the leaves then turns them yellow and they fall off. I cut back almost 3/4 of the patch in late spring and used an organic fungicide, which seemed to work until mid August. It’s back and I hate to keep using fungicide even if it’s organic.
Susan Vinskofski says
Hi Rachel, keeping good air circulation in your patch is essential. Try cutting them back to about 1″ above the ground this winter. Then in the spring when they begin to grow you may want to remove some of the canes to open things up a bit. You may need to use the organic fungicide again, but hopefully things will clear up.

I have a CSA farm with 1/2 acre in production. We have 5-50′ rows/beds of raspberries. 2 kinds. Heritage is the largest and Killarney comes in second. It is a spring bearer. Very heavy but we lose a good half of them due to black sap suckers. So we get two crops from our Heritage because our members (25 families) love getting them. We cut off the top that produced in the fall and as you said they will produce down the rest of the cane in the spring. Those then get taken out if we have the time. We don’t have the problems with the sap suckers in them as much till late in the fall. We used to have terrible problems with Japanese beetles but found the grubs, not in our lawn, but in the woodchips that were deep next to our greenhouses! Thousands of them. We used to let the chickens out for the winter but they made such a mess with the woodchips it wasn’t worth the extra work.
Patricia says
I meant to say we allow the new canes to grow up and they become the fall crop. The Killarney are terribly thorny and snake all over the place. Hate them despite them being much bigger and tastier!
Susan Vinskofski says
Those members are certainly blessed to have you!!!
