How to ensure a "new" raspberry plant

I am trying to match the advicd that raspberry plants last about 10 years with the fact that they put forth canes very year from roots and are propegated from root canes.  How do you start a new "young" plant?  I am wanting to start a new raspberry crop in a flood free zone. (as we have very bad water table flooding at times that sits for months)

i suspect letting tips of living canes root/layer is the easiest way to get ‘new’ plants. just dig up once they’ve rooted.

I agree with Greg.

Usually when a cane touches the ground the cane roots easily.

A little dirt over the cane might hasten the roots though I don't know since I have not done rooting this way.

I know it's not right, but I am brutal. I have raspberries that have spread to areas that they have no business being. I don't even use a shovel. I do water before i assault them though. I just run my fingers along the offending escapee's stock and find the way the root goes and pull it up. I carry a box with dampened newspaper to layer the plants into keep them moist before replanting them. I do this every spring and through out the season on cool days. Over the last ten years I've shared the overstock with at least twenty folks that now have raspberry patches.

Robert's method is how we got our raspberries, vigorous healthy plants of who-knows-what type, that also self-seed, given to us by someone in our town who had waaaay too many!
Meanwhile, the very expensive named varieties I bought bore a heavy crop of big luscious berries for one season then all died!

Thanks for these quick replies.  So basically if it is a runner from an older plant that has not put out canes at is base before, it is a new plant?    Could you grow raspberries by every few years putting down beside the old plant two one metre rows of weed matt with a gap between the two, and letting the rows make a new row of raspberries in the gap, and slowing ""Walking" them across the garden bed over the decades?

I've had success with taking cuttings of first year canes.  My raspberry is Royalty, which is half red, half black. It grows very tall canes that need to be cut down to 6' in the fall. It is planted in the wrong spot.

Last year I took all my prunings in the fall and stuck then in the ground at entirely the wrong time of year, right before frost. I planted at least 20. My dog pulled out a bunch. Some were upside down. A random wild critter stole some. I ran over some with a snowblower.

Anyway, this year I had 3 new raspberry plants where I'd put cuttings, and half a dozen baby plants that had come out at the roots of the original plant. All FREE.

This year, slightly less too late in the year, I took cuttings of the original plant, dipped them in rooting hormone, neglected then in wet sand for a months, and stuck them in the ground entirely too late, again. We will see what the success rate is this spring.

That's an interesting idea, Annie. I'm not sure how well it would work, as a metre might be too far for the older plants to send shoots. My new shoots tend to only come up a foot or so from the existing plants. But it would be interesting to try!

We had one raspberry plant at the high end of our front yard.
Now we have a yard full of them, born from neglect.
I recently began tending to them.
I tie all the canes of a given plant to a single stake.
Any cane that sprouts up too far from the stake to be tied up is dug up, and transplanted.
Any green branch that is removed is liable to be stuck into a sub-irrigated  barrel planter and ignored until it either gets big or shrivels up.
I never noticed any tip layering, but I have propagated the blackberries by tip layering them directly into buckets .
I'm new to black cap raspberries, but they are  aggressive in how they spread from cuttings or or tip layering on their own.
As far as I can tell they spread and grow over the winter as well as during the warm months.
Mind you their taste is divine.
Because of this, plus their thorns, I moved mine to my second property , where they can grow wild.

Hello all,
here is my first forum post. I'm posting this here for subsequent readers because I've already had great frustration on this topic. Here are my experiences to propagate
autumn raspberries ( fruits already on the one-year shoots).

Although the raspberries and blackberries are strongly related, the propagation of raspberries via cuttings or by tying down has not worked for me.
Only the propagation via root cuttings or naturally sprouting roots has worked.

For propagation via root cuttings, I dug up a plant about 2 months before the last frost and carefully removed the strongest root. After that, I put the plant back in normally. I cut the root cuttings into 4 to 5 cm lengths and put them in compost, watering occasionally. After the last frost, I put the plants, which were about 5 cm tall, where they should go. These almost all survived. However, there were not yet fruits on the young plants.

For the propagation via shoots I let the shoots grow over the summer and transplanted them in the fall. These will be bigger in the first year than the self propagated plants. These have also grown very well.

In conclusion, after the first year, the sprouting plants look stronger than the root cuttings. However, if you want to propagate the plants very quickly, I can also highly recommend the root cuttings.

One possibility, which I have not yet tried, is to cut the roots near the raspberry, for example, with a spade. The roots remaining in the ground should then also sprout and lost even less fine roots. If someone has experience with this, happy to share once.

Cheers Nils

What works great is rootcuttings, i moved thèm into shade ans sun. Hot or cold season, always a harvest.
Separating happens just by mowing around thé edge, mowing the grass in my case. They do keep creeping forward through the soil underneath. Into my veggiebeds. Where i just leave them mature a year. To be moved in november. Where i am, freezes are mild.
They're great gifts! Who doesn't love raspberries? Low maintenance when you have the right variety. Plant them together in patches. Seperated they seem to struggle.
Why? I guess because they like to move in the forest and on the edges of forest forward. They make shallow matrix/web like connected rootsystems in nature. I guess that makes them stronger. Separated they van take quietly sôme years before starting to spread.

Raspberries will do it on their own.  I had a neighbor across the road who planted a "fancy" golden raspberry. His dog dug it up and shredded it. The next summer I had golden raspberries showing up in my back garden where the grey squirrels like to dig. I gave him about half the young plants to plant somewhere the dog wouldn't find so offensive.

Layering raspberries sounds like way to much work. Raspberries have a Napoleon complex and are out for world dominion. We've always just dug up the spreading shoots that came up in the yard and have them away to whoever would take them. It was the only way to keep them out of the yard. This year I'm experimenting with digging up the roots over the winter and planting them still dormant. It's definitely easier to do since my raspberries now are grown under a lot of wood chips.
Raspberries are definitely a wonderful, low maintenance fruit.
