Let them all grow for now for the simple reason you will not be able to tell which ones are going to be the strongest at this time.

Then later in the year do as you have described and thin out the weak and badly placed canes.

What did it look like last year ? May be the answer is to keep it small...im not an expert but i find that most plants that are allowed to grow alot of green dont produce alot of flowers... ? ) my granddad used to say the knack was to have more going on under the soil then over it....how true this is i couldnt really say ..sorry ! You could try finding other members through searching raspberry cane because not everyone looks at the Q. Section or may be try hywel ..he seems quite to know alot and is very helpful :-) sorry not much help i know ...good luck x

Cacti raspberries are a 'cane' plant they need to grow a cane of approx 1.5 metres to flower and fruit. Lawley follow Teegee's advice and let them all grow pruning out any very thin or awkwardly positioned canes. Don't expect a huge crop this year and prune back all the cane that have fruited as soon as they finish doing so and trim the new growing canes or they will, like a bramble, just keep on growing.

Thank you so much for all your advice, Moon Growe I will follow Teegee's and your advice. I will not expect any fruit this year but just happy that I will be able to save them and hopefully produce a great crop next year!

Teegee.... The gardenersalmanac.co.uk which I saw on your profile page is great a webgsite I will use in the future, very useful. Thanks

Moon Growe... I also had a look at your profile page and saw your Moon website... Great another website I will find very useful..Thanks

Sorry MG, what do you mean by "its now an archive"?

Thanks. Learning all the time! I hope you meant to put "it" on the end of that sentence MG?

Yup I did :-)
