Raspberry riddle...
No, not a new sort of ice-cream.
Earlier this year, in an effort to regain some control over the very seriously overgrown veggie patch in our new house, we trimmed all of the raspberry canes down to about a foot high. Various people threw up their hands in horror, saying that if they were a summer fruiting variety, we wouldn't get any raspberries this year. Now it's summer however, we *do* have fruit. I recall too how at our previous house we were delivered a number of bare-root raspberry canes trimmed to a similar height late one winter and planted them out, getting fruit in the summer of that year. Why's that then? Is this summer fruit on old wood/autumn fruit on new wood thing all a bit of a generalisation? James |

I would expect that your fruit is on off shoots from the foot high canes, not on canes that have newly sprung from the base. The flowering/fruiting pattern of many of the rosaceae (which includes raspberries) is Year 1: - throw out long new canes/branches to get as high as possible Year 2: - (as well as throwing out yet more long new canes) producing flowering side branches from last year's canes Year 3: - throw out new canes, produce flowering side branches from last years canes, continue flowering from the side branches of the first year's canes - but since the plant has grown in vigour since then, these won't e quite as fruitful as the ones from the second year ... .... and therefore the pruning regime is - cut out completely (down to the ground) the canes that fruited last year, to concentrate all the energy on the more vigorous canes from last year which are branching and fruiting this year, and allow to grow the new canes which will bear next year's crop. Of course, of you tell me that this year's new canes are fruting (as opposed from branches from the foot long stumps) then I have to re-think my whole understanding! -- Kay "Do not insult the crocodile until you have crossed the river" |

We are just coming to the last of a big crop from those shortened canes. At the same time huge new canes have grown and are already budding up flower trusses for autumn cropping. The summer crop have been good sized fruits and from last year, the autumn ones will be huge berries. Later on we will cut the new canes as before, they will also need some thinning out. -- Alan & Joan Gould - North Lincs. |

I also have an overgrown mass of raspberry canes which I know to be
part summer, part autumn fruiting. At the beginning of last year I cut them all to the ground and they all fruited well in the autumn, over quite a long period, up to the frosts. I shall certainly try cutting some to 1 foot which sounds an excellent two-bites-at-the-cherry! Pam in Bristol |
